How to Replace a Lägler HUMMEL Sanding Drum

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.

  1. Remove the sanding belt from the tensioning roller and the sanding drum.
  2. 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.
  3. Turn the sanding drum so that the key way is at the top of the drum, pointing toward the ceiling.
  4. 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.
  5. Clean the shaft. Mild lubrication is helpful.
  6. Slide the new drum onto the shaft, making sure to align the key way as needed.
  7. 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.
  8. 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.

Lägler Certification: What is Lägler PST®?

Lägler’s certification program – Premium Sanding Technology (PST) – is about two things: our relationships with contractors, and their success with sanding and finishing wood flooring.

Many sanding professionals across the world know Lägler machines, especially the HUMMEL, the TRIO and the FLIP. Those are the three sanders used during the one-day certification class. PST is about showing you how to maximize efficiency on the job while getting consistent, top-quality results with those machines.

In the 10 years since Lägler created PST and starting offering it at its headquarters in Güglingen-Frauenzimmern, Germany, employees of more than 2,500 companies have been PST certified.

What Is Lägler’s PST Method?

The Premium Sanding Technology method is about consistency on the job. It’s about maximizing efficiency. It’s about applying the same exacting process no matter the species or pattern of wood flooring, and getting the same, top-quality results every time.

Hint: It’s HUMMEL, FLIP, TRIO, FLIP, TRIO, FLIP, TRIO. With the proper uses and grit sequence taught during PST training.

What Is Covered in PST Training?

The one-day course starts with an hour of classroom time, covering:

  • History about treatment of wood floors
  • Types and uses of different machines
  • Ergonomics of handling the machines
  • Job safety (e.g. dust emissions)
  • Sanding techniques
  • Grit sequences

The rest of the class is hands-on training, using the HUMMEL, TRIO and FLIP with the PST grit sequence. The PST trainer will use a stopwatch to time each step in the sequence, showing how time is saved throughout the process. You also learn tips for use and care of the machines.

How Much Does Lägler Certification Cost?

Straight out, the price of attending PST is cheap. Class sizes are kept small to maximize each participant’s opportunity to be hands-on and get questions answered. At $275 total for up to five attendees per company, it is not a money-maker for Lägler.

The pre-paid registration for PST is about receiving the commitment of those who signup, and it goes toward covering some of our training expenses. For example: flooring supplies, training materials and your lunch.

 

Why Does Lägler Offer PST Training?

Relationships. Serving customer needs. The more face-to-face time we get with customers, the better it is for all of us. We don’t just teach, we learn.

We also take the long view. For example, a HUMMEL is built to last for more than 30 years, if properly used and maintained. So PST helps you know how best to use and care for your machines.

Of course, we don’t sell as many machines, because they are built to last. But when you understand how to get the most out of them, how to trust your machines day in and day out, you know you can trust us too. When you do need something, like parts or information, we’re here.

Our goal is to help you succeed in business for the long-term. That helps us to have a strong business future, too.

PST training is offered in three locations:

  • Lägler North America in Denver
  • KHR Floor Sanding Supplies in Southampton, U.K.
  • Lägler GmbH in Germany

Schedule PST training for an available date that suits your needs: email [email protected] or call 800-8-HUMMEL.
