How to Replace the Lägler FLIP® V-Belt

November 29, 2017/in Lägler /by webmaster

Have you noticed your Lägler FLIP^® acting a bit different lately? Maybe you’re having a tough time starting it or the working speed has decreased.
Maybe it feels like it isn’t running as smoothly as usual or the noise has gotten louder. The FLIP might be losing its steam to suck dust. It’s maintenance
time.

All machines need a hug from time to time, and parts need to be replaced. It’s no different than routinely changing the oil on your truck. New oil, smooth
ride.

New V-belt, new edger.

</p> <p>

Over time, residue accumulates in the pulleys and in the attachment. The issues mentioned above start happening and you know it’s time to take a look under
the hood and replace the V-belt. While you’re there, check whether the fan housing and blades to see if there is buildup there that needs to be dealt
with too.

The V-belt must be replaced, at the latest, when it cannot be retightened because the screws for connecting the attachment are at the end of the holes.

Special note: The V-belt should run without touching the ground of the pulley. The belt’s left and right edges should rest against the inner edges
of the pulley.

Step-by-step instructions for removing and installing the V-belt for the Lägler FLIP edger are listed below. They also are shown in the video above, using
the illustrations from the Lägler FLIP Operations Manual.

How to Remove the V-Belt on the Lägler FLIP

Assuming you’ve already turned off and unplugged the FLIP:

1. Lay the machine on its side or with the motor housing on a table. Avoid damages to the floor or table and the machine.

2. Undo the screw of the belt tightening plate (at the back of the attachment) with the universal spanner, the special T-grip driver (P1230 | 000.91.40.001) that comes with the purchase of a new FLIP.

3. Turn the belt tightening plate away from the attachment and re-tighten the screw of the belt tightening plate.

4. Use the universal spanner to remove the two screws that connect the attachment, along with the washers and the guide angles. Place these parts to the
side.

5. Remove the attachment from the machine and put down the attachment with the sanding disc facing upward.

6. Use the universal spanner to undo the fixing screws of the attachment cover and remove this from the attachment.

7. Turn the attachment over.

8. Use the universal spanner to undo the four fixing screws of the complete sanding disc.

9. Remove the attachment from the complete sanding disc.

10. Dispose of the worn-out V-belt.

11. Check whether the sanding plate pulley or the motor pulley are worn-out. Replace these parts if necessary. If one pulley appears to be worn out, then
both will be. Here are two signs of a worn out pulley:

The edges of the belt slip down into the groove of the pulley.
The pulley groove is polished from the belt running directly on it.

12. Clean the two pulleys and the attachment. Wear a respiratory protective mask if necessary.

How to Install the V-Belt on the Lägler FLIP

1. Place the new V-belt on the complete sanding plate pulley.

2. Insert the complete sanding plate with V-belt in the attachment. Ensure that the holes of the complete sanding plate are aligned with the holes in the
attachment.

3. Make sure the sanding plate can be turned by hand and the V-belt is correctly placed in the attachment.

4. Turn the attachment over and tighten the four screws for attaching the complete sanding plate using the universal spanner.

5. Push the attachment over the motor pulley and insert the V-belt into the motor pulley.

6. Put on the attachment cover.

7. Tighten the two screws for connecting the attachment, placing a washer and guide angle in the respective threads of the fan housing. Do not tighten the screws all the way yet.

Make sure the belt tightening plate is not located between the attachment and the fan housing. Otherwise, a significant amount of dust will escape
from this area during sanding.

8. Tighten the V-belt. (See the “How to Tighten the Lägler FLIP V-Belt” section below.)

After a few days’ use to break-in the new belt, check the belt tension. Tighten again as necessary.

How to Tighten the Lägler FLIP V-Belt

1. Lay the machine on its side or with the motor housing on a table. Avoid damages to the floor or table and the machine.

2. Use the universal spanner to loosen the two screws that connect the attachment to the fan housing.

3. Use the universal spanner to loosen the screw that attaches the belt tightening plate.

4. Hold the FLIP^® by the fan housing and press the belt tightening plate forward toward the attachment at the same time with your thumb. Use
your other hand and the universal spanner to retighten the three screws.

HUMMEL. The Icon Builders.

January 17, 2017/in Lägler /by webmaster

This ain’t Vegas. What happens at the Lägler factory in Germany does not stay in the Lägler factory in Germany. It gets shipped near and far to floor guys
in 142 countries.

Take the HUMMEL. The icon in floor sanding. The HUMMEL didn’t become the most-recognized “big machine” in the industry overnight. It launched in 1969,
the world’s first belt sander. Many tens of thousands of them are the heart of flooring businesses worldwide today, whether the guy running it gets
paid in dollars, euros, pesos or pounds.

The HUMMEL is the heart of Lägler company, too, which has more than 60 years as a privately owned family business. Founded by Eugen Lägler, the legacy
continues in the hands of his son, Karleugen Lägler.

That explains a lot about the consistent quality of the machines. Steady vision, keeping the HUMMEL on-point with its past while being adaptable for the
future. Got a 40-year-old machine in need of parts? No problem. New parts fit.

Another key to this consistent quality comes from the men on the factory floor. They have a few years to a few decades of experience in the guts of that
one machine. Each man has had a part in sending thousands to tens of thousands of HUMMELs out the door and onto floors.

Start to finish, it’s these Lägler craftsmen that make HUMMEL happen. Fabricating, welding, powder coating, hand assembling, and testing the more than
100 parts assemblies for each machine.

Few parts come from outside the factory and outside the hands of Lägler employees. But those that do are made by partners nearby, following Lägler designs
and using custom tools made in the Lägler tool shop.

This is why the Lägler HUMMEL is recognized by flooring guys worldwide. This is how it earned its rep as an icon of floor sanding. This is why we say,
“Hand Built in Germany. Hand Approved Worldwide.”

Watch the three-minute behind-the-scenes story of these men who make of the HUMMEL.

How (and Why) to Level the Wheels of the Lägler HUMMEL®

January 3, 2017/in Lägler /by webmaster

How to Level the Wheels of the Lägler HUMMEL^®

OK, so you’re on your way into the house, carrying your HUMMEL. It gets dropped. It takes a lot to throw out of whack the wheel setting on your Lägler
HUMMEL^® but it can happen in a moment like this. Seeing and fixing the misalignment is super-easy once you’re in the house and ready to
fire up.

Top Two Things You Need to Know

1. How to know your Lägler HUMMEL wheels are not level with each other

2. How to realign the wheels of the Lägler HUMMEL for best sanding

How to Know If Your HUMMEL Wheels Are Aligned

If the wheels are not set at the same height, the machine will lean slightly. That will cause uneven wear on the abrasive that will be obviously visible
on the belt. And an off-center mark will be obvious if you tap a footprint on the floor to test the cut. An uneven machine will leave an uneven mark
on the floor.

When the wheels are set properly, the center of the drum is where the cutting happens, so you will see a symmetrical sanding footprint on the floor and
even wear on the sanding belt. [Note: This is why you should not dress a Lägler drum. It is designed for cutting from the high spot of the drum to
improve sand paper tracking. It also prevents the edges of the paper making contact with the floor and leaving lines.]

The short video above shows the difference between an uneven sanding mark and one that is nicely balanced at the center of the drum.

/_photos/WheelLeveling-drawing.JPG

How to Adjust HUMMEL Wheels for Best Sanding

Like basic maintenance with all Lägler machines, there is a simple Lägler tool for the job. And, if you bought your HUMMEL new, the tool for leveling the
wheels came with the machine. Don’t have the tool? Check with your area Lägler dealer or on our website using these part numbers: P233 (Lägler N.A.) and 100.00.50.100 (manufacturer). You also will need a 13mm wrench for loosening the tension screw of the adjustable wheel (one comes
with buying a new HUMMEL).

The wheel on the belt-guard side is fixed in position with a screw. The wheel on the other side is adjustable, and the tension screw for that is marked
on the machine with a black arrow. Your goal is to move the adjustable wheel up or down as needed to set it at the same height as the position of the
fixed wheel.

The video above is a quick how-to demonstration for setting your HUMMEL wheels at the same height.

2 Tips for Leveling the Wheels of Your HUMMEL

If you are cutting more heavily to the left, the adjustable wheel will need to be lowered toward the floor, taking it a little further down out of the
“wheel well.” (See A and B in drawing below.)

If you are cutting more heavily to the right, or belt-guard, side, the adjustable wheel will need to be raised, sliding it a bit further up into the wheel
well of the machine housing. (See C and D in drawing below.)

Why You Should Sand Wood Floors at an Angle + Left to Right

We’ve refined our thinking on sanding at an angle. For example, we used to recommend cutting at an angle for the first pass, and then with the direction
of a straight-laid floor for finer grits.

Now, we recommend using at least a slight angle for each pass. It’s all about getting the flattest results.

We also explain why to sand left to right as you move across the field of a room, and why you should not sand right to left, if you want to achieve the
best results.

Lägler TRIO: How to Change the Tooth Belt

November 2, 2016/in Lägler /by webmaster

Good condition of the tooth belt, or the belt that turns the three sanding plates (discs) of the Lägler TRIO fine sanding machine, is critical. No belt,
no sanding. It’s that simple.

In this post, and the video below, we give step-by-step instructions for removing the current belt and replacing it with a new belt.

How to Know When the Tooth Belt Needs to Be Changed

It can be difficult to know when to change the belt, unless it’s the most obvious situation: a three- or four-year-old belt that has dried and become brittle,
and then breaks. In that case, the sanding discs will not turn.

Otherwise, a common way to recognize when the tooth belt needs to be changed is to notice decreased RPMs and less dust filling the dust bag.

How to Remove the Tooth Belt

Starting with the machine turned off and unplugged from power:

1. Lock the handle into its forward position, using the clamping lever at the front of the handle.

2. Lean the TRIO backward to rest safely on the two protective cushions at the back-bottom of the machine’s frame, and on the guide tube.

3. Remove the sanding plates by grabbing the edges and pulling the plates away from the machine, disengaging the TRIO’s three prongs from their rubber
jigs. Caution: Do not use a screwdriver or other tool to pry the plates away from the machine; prying with tools can cause damage.

4. Remove the eight screws of the cover and remove the cover. Recommended: Check the sealing felt on the inside of the cover and replace as needed.

5. Loosen the counter nut of the belt tensioner, using a 17mm wrench, by turning the nut all the way back against the casing wall.

6. Expand the spring by turning the second nut back to the counter nut.

7. Push the belt tensioner back and remove the belt.

8. Use a vacuum to remove dust and dirt inside and around the pulley mechanism.

How to Insert a New Tooth Belt

1. Push the belt tensioner all the way back to the casing wall.

2. Insert the new belt with the geared side facing and engaging the pinion gearing, with the flat side of the belt skirting the gear bearings.
Caution: Incorrectly inserting the belt can cause damage to the machine.

3. Tighten the spring using the nuts to adjust the spring to the proper length:

a. Orange spring: 55 millimeters (approx. 2 1/8”)

b. Blue spring: 52 millimeters (approx. 2”)

4. Replace the cover, fastening it with the eight screws previously removed

5. Mount each sanding plate by first inserting one of its three prongs (locking bolts) into one of the rubber jigs, then fitting the other two into their
respective positions. Press the plate into position as far as it will go.

6. The belt replacement is complete. Stand up the TRIO, readjust the handle to your preference for use. You’re ready to sand again.

How To Remove the Lägler HUMMEL Motor

September 7, 2016/in Lägler /by webmaster

The Lägler HUMMEL weighs about 175 pounds. That weight is important for sanding wood floors with the HUMMEL, but it’s no doubt tough on your back when
carrying the machine for long.

Any of you who have worked a multi-story job alone and have lifted it up a flight or two of stairs without taking off the motor know what I’m talking about.

Here are simple instructions, as shown in the short how-to video below and on our Lägler North America YouTube channel, to separate the HUMMEL motor from its chassis to make much lighter
work of carrying the machine.

Tools Needed to Remove the HUMMEL Motor

The tools you might need are:

Box wrench (LNA #P232 | Mfr. #100.00.45.105) or channel lock pliers
6 mm hex wrench
17 mm crescent wrench

Easy Step-by-Step Instructions for Removing the HUMMEL Motor

Step 1: Make sure the sanding drum of the HUMMEL is raised off the floor and that the machine is turned off and unplugged.

Step 2: Open the belt guard by loosening its screw, using a 6 mm hex wrench, if needed, and swinging the guard out of the way.

Step 3: Release the tension in the drive V-belts by loosening the eye bolt. Use a 17 mm wrench, if needed, to initially loosen the bolt.

Step 4: Remove the drive belts from both pulleys.

Step 5: Disconnect the kill-switch cord.

Step 6: Loosen the two motor nuts enough to allow you to pull the motor off the HUMMEL chassis. Do not completely remove the motor nuts.

To re-attach the motor to the HUMMEL, perform the steps listed above in reverse order.

When replacing and re-tensioning the drive belts, the trick is to tighten the eye bolt until there is one-quarter inch of flex in the belts. Don’t just
screw the eye bolt down to the exact same spot it was in prior to removing the motor.

How to Clean the Lägler TRIO Filter

July 13, 2016/in Lägler /by webmaster

Have you seen our tag #MaintenanceMatters? We use it on Instagram, Facebook and Twitter. Because it’s true, maintenance matters to your machines and your business’ success. Plus, we like to talk about the matters of maintenance.

So here’s another one that should be happening every day when you use your Lägler TRIO fine wood floor sanding machine.

Three things to know about cleaning the TRIO fine sanding machine filter unit:

The filter should be cleaned after each dust bag change; it only takes a few moments.
Do not blow compressed air into the dust bag container or the neck of the suction hose; it can damage the pressure control sensor.
Failing to clean the filter unit will decrease dust suction, make the TRIO perform less efficiently, and dust emission into the environment will increase.

Three Steps to Basic Cleaning of the TRIO Filter

There are only three steps to knock the dust out of the filter and into the dust bag, assuming you already have turned off and unplugged the machine. These steps only take five seconds:

Grab the wing screw on top of the filter unit on top of the TRIO, then gently pull it upward. That moves the cleaning rod and brushes located inside
the filter unit. Watch the video above to see how the TRIO’s internal filter cleaning system works.
Slowly turn the wing screw side to side, back and forth; then move it up and down a few times, knocking dust into the dust bag.
When finished with step two, push the wing screw/slide all the way down, or the machine’s suction will be decreased.

If these simple steps do not sufficiently clean the filter or if it seems like you are needing to repeat this cleaning process too often, the filter likely
is clogged.

In that case, you need to dismantle the filter unit for more thorough cleaning. Read “How to Dismantle and Reassemble the Lägler TRIO Filter Unit.”

How to Replace a Lägler HUMMEL Sanding Drum

June 29, 2016/in Lägler /by webmaster

Two important things you need to know about the Lägler HUMMEL sanding drum:

Do not dress the drum
Drum replacement is easy

The HUMMEL sanding drum has a slight “football” shape to it. Dressing it ruins that design, affecting wood floor sanding results. Dressing a HUMMEL sanding drum causes poor sand paper tracking and chatter, among other problems.

Replacing the drum takes only one to two minutes, whether at your shop or on the jobsite. Instructions for “Replacement of the Sanding Drum” are in the
operating instructions manual that comes with the purchase of each new HUMMEL.

Here are the highlights for how to replace the Lägler HUMMEL sanding drum, as shown using a 1983 HUMMEL and new parts in the short video above. We’re assuming
you’ve already unplugged the machine, have removed the side cover, and have tilted the machine back to rest on its handles and the safety guards at
the bottom.

Remove the sanding belt from the tensioning roller and the sanding drum.
Loosen and remove the drum nut, using the box wrench that comes with purchase of a new HUMMEL, by turning it clockwise (that means
righty-loosey, not lefty-loosey). You will need to loosen the nut with a mallet tap on the wrench handle.
Turn the sanding drum so that the key way is at the top of the drum, pointing toward the ceiling.
If the drum does not move easily from its shaft, use the handle of your mallet or an appropriately sized piece of wood to gently pry it loose, starting
to move it off the shaft. Do not hit it with a hammer; that will damage the drum.
Clean the shaft. Mild lubrication is helpful.
Slide the new drum onto the shaft, making sure to align the key way as needed.
When putting the drum nut back onto the shaft make sure to put the side that has a few “missing” threads toward the drum. Otherwise, the drum will
not be secured in position; it will move on the shaft during use, which can cause chatter on the floor.
Put the side cover back on, stand the machine up, and get back to work.

We recommend you replace a HUMMEL sanding drum once per year to maintain quality sanding results. If you need to order a replacement drum
or other HUMMEL parts, talk with your local distributor, shop online at www.laglernorthamerica.com or call Lägler North America at 800-8-HUMMEL.

What is Lägler Certification?

FLIP: How To Replace Carbon Brushes

May 25, 2016/in Lägler /by webmaster

Do you know how many carbon brushes there are on the Lägler FLIP edger sanding machine?

If you aren’t sure, it’s probably worth a quick check to make sure they are in good working shape. Our one-minute video shows the one tool you need for the job, where the brushes are, what they look like when they are excessively worn, and when they are new.

Our video shows three easy steps for carbon brush replacement.

SIGNS OF EXCESSIVE WEAR

Carbon brushes should be replaced once per year to avoid damage to the FLIP motor. The brushes include safety contacts that automatically shut off the motor when the wear limit is reached.

If the power switch on your FLIP no longer stays turned on and you are needing to hold the switch in the on position, it’s a strong sign it is time to replace the brushes. Continuing to use the FLIP in this condition will lead to switch and motor damage.

Another key sign, if the auto shut off is ignored, occurs when the motor starts to burn. You also might see sparks. As you can guess, your repair costs increase significantly when this happens.

HOW TO REPLACE THE CARBON BRUSHES IN A LÄGLER FLIP

Step-by-step instructions are in the manual that accompanies each FLIP when bought new. Here are the key steps, which are shown in our how-to video:

Unfasten the four screws on top of the FLIP and remove the top cover (handles) from the motor housing.
For each carbon brush, detach the connectors, then gently push the brass, coiling pressure clamp to the side. Remove each worn carbon brush.
For each carbon brush, insert the new brush, holding the pressure clamp out of the way until the brush is in place. Attach the connector.
Re-install the handles/cover atop the motor housing.

MINIMIZE COSTS OF MAINTENANCE Back to the question I asked at the beginning of this post: How many carbon brushes are part of your Lägler FLIP? The answer is two. Don’t forget to check and replace both brushes. Preventive maintenance always is less costly for the bottom line of your business. Some simple math below highlights how much of a difference it will make if you replace your carbon brushes at the right time versus if you wait too long.

A new carbon brush will cost you a little more than $20. So you can plan to spend a relatively modest $45 for two, plus shipping, as applicable. (I also recommend keeping a spare pair of carbon brushes in your truck.)

Compare that to needing to buy a new switch and motor, on top needing a pair of brushes. Those will add about $800 to your bill.

Needless to say, that’s a huge difference. So watch our one-minute how-to video about replacing the carbon brushes in your FLIP. It will be well worth your time.

Where to Buy New Carbon Brushes

As with all Lägler parts, talk with your local distributor. If you are in the U.S. or Canada and you do not have a local distributor, Lägler parts are available online at laglernorthamerica.com.

The part number you need is P1228, if buying online from Lägler North America. Otherwise, use the manufacturer number that is globally recognized: 000.65.84.012.
