Q: How to correctly reattach the tension roller and tension arm after removing them?

When you reattach the tension roller and tension arm on your ELU MHB90E, the following issues may cause something to "catch": Common problems during reassembly The tension roller is misaligned - The roller's shafts must be completely symmetrical in both mounts. Ensure it is fully inserted at both ends before using the tension arm. The sanding belt is mispositioned - Make sure the sanding belt (100 x 560 mm) is already correctly mounted on the roller before attaching the tension arm. The belt must be centered on the roller. The tension arm collides with the centering button - Your machine has a centering button that adjusts the belt's position. Ensure this is in the neutral position and not in the way when lowering the tension arm. The spring or retention mechanism is mispositioned - If you have removed a return spring or elastic element, check that it is correctly reinstalled before assembly. What you can do: First, attach the tension roller without the tension arm and turn it manually to ensure everything moves freely. Then, slowly attach the tension arm and feel where it exactly catches. Check the assembly sequence in the printed manual (especially pages 2-3 for this model).

Question 1

The tension lever of the belt won't go in, something is blocking it - how to unblock?

Accepted Answer

If the tension lever of the belt (part no. 12) won't go in or seems stuck when pressed, it usually indicates improper insertion or overlapping of the sanding belt on the rollers.

How to unblock:

Check the positioning: Place the sander on its side with the lever facing up. Ensure that the sanding belt is properly centered on both rollers and does not overlap the edges.
Release the tension: Pull the tension lever firmly upwards and to the right to completely loosen the belt. A poorly installed belt creates resistance when reinserting the lever.
Reinstall the belt: Rethread the sanding belt ensuring its alignment, then gently push the lever down to reapply the tension.
Check for damage: Inspect the lever and rollers for any deformation or debris that may have accumulated.

If the lever remains stuck after these steps, the tension mechanism may be damaged and require repair.

Question 2

Where to order a new tension arm for the MHB90E?

Accepted Answer

The tension arm is a wear part of your ELU MHB90E slip machine. If it is damaged or worn, it can be ordered as a spare part from the manufacturer ELU or its authorized dealers.

To obtain this part, we recommend:

Contacting ELU customer service with the full reference of your device (MHB90E) and the specific part number of the tension arm;
Consulting your user manual which contains the contact details for ELU technical support;
Checking with authorized ELU dealers in your area, who can order spare parts;
Ensuring that the new tension arm is compatible with your model (MHB90E, sanding surface 100 x 110 mm).

Wear parts like the tension arm should be replaced regularly according to your frequency of use.

Question 3

What to do if the tension roller does not tighten properly and something is snagging on one side?

Accepted Answer

If the tension roller (spännrulle) cannot tighten properly and you feel resistance or snagging on one side, it is usually due to a misalignment of the abrasive belt.

Solutions to try:

Check the belt alignment - Before tightening, ensure that the abrasive belt 100 × 560 mm is centered on both rollers. A misaligned belt will block the tension.
Use the centering button - Your model MHB90E has a centering button (centeringsknapp). Press it lightly to adjust the lateral position of the belt until it is perfectly centered and free.
Check the tension lever - The tension lever should move freely. If it snags on one side, it is often a sign that the belt is misaligned or that a grain of dust is blocking a roller. Clean the inside with a soft brush.
Check for debris - Carefully inspect both sides of the tension roller (part 11 of the diagram). If something is visibly snagging, clear any obstacles or residue.

If after these checks the roller remains stuck, it is likely an internal mechanical issue that requires servicing.

Question 5

How to buy a compatible stand for the ELU PS274E saw?

Accepted Answer

For your ELU PS274E saw, the official compatible stand is the foot support (reference 31), which is listed among the accessories recommended by the manufacturer. It is an essential item if you wish to use your saw in a fixed position, especially for working on long pieces of wood.

The foot support (31) is sold with its assembly instructions. It generally comes with short support bars that can be replaced by non-standard rails depending on your work setup. This stand is designed to be sturdy and stable, allowing your saw to operate optimally on a dedicated work table.

Where to buy this stand: Contact your specialized ELU dealer directly, as they can advise you on the accessories that best suit your use. You can also visit DIY stores that offer ELU spare parts (Leroy Merlin, Castorama, Bricorama) or specialized sites in power tools. Ask for the reference 31 to ensure you order the correct model compatible with your PS274E.

The advantage of the foot support (31) is that it integrates into a coherent set of accessories recommended by ELU: you can then add guide rails (26), adjustable supports of 760 mm (30), a roller table (33), or other elements according to your needs. This modularity allows you to gradually configure your setup.

Important: The manual emphasizes that only accessories recommended by ELU should be used to ensure the safety and performance of your machine. Using unapproved accessories could pose a risk of injury. Therefore, prioritize original or officially compatible parts.
