How to Remove the Lägler TRIO V-Belt

January 31, 2017/in Lägler /by webmaster

How to Remove the Lägler TRIO V-Belt

Our how-to blog posts like this one are all about helping you to solve your maintenance questions, especially when you’ve got a tight schedule and need
to keep running. But to do that, the first thing you need to know is how to tell when a part needs repair or replacement.

When to Replace the Lägler TRIO V-Belt

As much as we’d love to be able to put out a maintenance schedule that follows exact amounts of usage or length of time for certain parts, you know there
are too many variables for us to do that. Especially with rubber parts like the V-belt.

With the Lägler TRIO V-belt, if it shows signs of wear and tear, replace it. You don’t want to nitpick over squeezing out another job with a worn belt
and end up with lost time on a job site because you pushed too far. Our recommendation is to keep a spare V-belt on-hand, especially if you think the
amount of wear is questionable.

Now, on to our step-by-step instructions for how to remove the TRIO’s V-belt.

How to Remove the Lägler TRIO V-Belt

With the TRIO turned off and unplugged, follow these steps:

1. Remove the tooth belt. (Need help? Read our step-by-step instructions: “How to Change the Tooth Belt.”)

2. Bring the machine back into its upright position.

3. Loosen the cable plug of the sensor on the on/off switch by turning the ring nut counterclockwise, and pull off the cable plug off.

4. Remove the on/off switch from the chassis and hook it into the transport holder on motor switch box.

5. Pull the suction hose from the neck of the upper part of the separator.

6. Loosen the two cross-grip fasteners at the side by which the chassis is attached to machine housing and move the chassis backwards.

7. Remove the screw that fixes the V-belt guard to the fan insert.

8. Pull V-belt guard from its slot at the motor and put it aside.

9. Release the tension of the V-belt by carefully moving the V-belt tensioner using cranked closed-mouth wrench. The V-belt can now be disengaged from
the pulleys and the belt tensioner.

10. Release the tensioner to its regular position.

11. Remove the four screws that fix the motor to the machine housing and lift the motor off, keeping it in a vertical position. The V-belt now can be removed.

12. Use a vacuum to remove dust and dirt.

To get your TRIO back in action read, “How to Mount the Lägler TRIO V-Belt.”

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.

HUMMEL Manufacturing | Built by Hand in Germany

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.

Lägler HUMMEL. Hand Built in Germany. Hand Approved Worldwide

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.

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.)
