Checking/adjusting/replacing the V-Belt
The belt tension is set correctly for new machines ex factory. By stretching the belts over the
running time, retensioning of the belt is necessary.
To check/adjust or replace the belt, remove the belt/chain cover. Loosen the screws and remove
the cover.
Increase belt tension:
Loosen nut (S1) and unscrew slightly. With the
nut (S2) the motor can now be shifted in the
direction (+) of more belt tension.
When correct tension is reached. Tighten the
nut (S1) firmly again.
For changing the V-belt, completely de-tension the belts and pull them over the tension pulleys
and insert new belts. Then establish correct belt tension again.
After completion, remount the cover and fix it with the screws.
18.4 Lubricate height adjustment (thicknesser)
Remove chips and dust from the machine.
Remove the belt/chain cover (loosen the screws and remove the cover).
Set the thickness table all to the top.
Clean spindle/height adjustment unit and then grease with machine grease.
Move the thickness planing table 1x up and down to distribute the grease.
Mount the cover again (hang in the cover and tighten the screws).

Check/clean anti-kick-back device
Check: Lift up Anti-kick back device, it must fall back on your own.
Cleaning: Remove dust and chips or resin residues.
18.6
Check/replace friction wheel (feed)
The friction surfaces of the wheel become worn over time. If the wear is too worn or damaged, the
wheel must be replaced.
1.
Remove V-Belt
2. Put the lever for the thicknesser planer feed to the lower position (deactiated)
3. Remove the screw for the belt-pulley and replace the wheel and fix it again.
4. Insert V-Belt and re-establish the correct belt tension.
18.7
Check/lubricate chain-drive (feed)
Check the chain for any damage (cracks, break-outs). The chain can be moved by turning the
friction wheel to view all parts. Lubricate chains with normal machine grease.

CLEANING, MAINTENANCE, STORAGE, DISPOSAL
Check for damage/wear, lubricate, replace if necessary
Check for damage/wear and replace if necessary.
Decrease belt-tension:
Loosen nut (S2) and unscrew slightly. With the
nut (S1) the motor can now be shifted in the di-
rection (-) of less belt tension.
When correct tension is reached. Tighten the
nut (S2) firmly again.
N O T E
Do not over-tension the V-belt!
Tension the V-belt only until
sufficient power transmission is
ensured.
