Replace Rubber Rollers
Preparation:
•
Provide 2 pcs. support blocks to support the front sheet metal covering.
•
Plane a piece of squared timber with min. 150 mm on the right side of the thicknessing table (length ap-
prox. 1.5 m). Then stop the feed; the workpiece must rest under the infeed and outfeed roller as support.
•
Switch off the machine, turn off the main switch and lock it!
Switch off the machine during maintenance and repair work and secure it against being
switched on again unexpectedly! Lock the main switch with a padlock!
Step 1
Supplementary to Step 1
Remove the front sheet metal cover and place it
sideways on the 2 support blocks.

Step 4
Pull out the rubber segments from the main shaft to the front. Let segments 2 - 5 (by hand and preferably
with the help of a second person) be pushed above the thicknessing table. For this purpose the prepared
squared timber with min. 150 mm thickness serves. Now push the new segments onto the shaft.
Step 5
Place the sleeve and the shim washer and push them in. Important: The black sealing ring must be fitted
properly. Use a press-in tube or a piece of wood and a rubber mallet to carefully tap the pendulum bearing
inwards. Then tighten with the M8 screw (SW 13) and washer.
