Another tip:
If you have achieved a level surface after several pro-
cessing operations, it is recommended to run several
more operations using a smaller infeed for a better sur-
face quality.

Repair and Maintenance

Always disconnect the mains plug for any adjustment
work! Risk of serious injuries or damage due to inadver-
tent starting up of the device, or hazard due to electric
shock!

Replacing or reversing the planing knife (Fig. 8):

The knife shaft of your planer is equipped with 2 reverse
knives for the best surface quality. Each of the utilised
planing knives has two cutting edges (reverse knife). If
the first becomes worn or damaged, you may simply
remove the knife, reverse it and use the other side. If this
is not sharp enough either, then please insert new
knives. Please remember to always use or replace the
knives in pairs! You will find replacement knives in spe-
cialist shops.
Use only the spare knives intended for the machine!
It is not permitted to resharpen used planing knives!
Please, always replace or reverse them! Immediately
replace damaged planing knives!
Please handle the knives with extreme caution as they
are extremely sharp! Risk of injury!
1. Set the receiving table 1 (Fig. 8a) to the lowest posi-
tion using knurled screw 2 in order to optimise the
accessibility to the knife shaft.
2. Turn the knife shaft 3 to a position to where the Allen
screws 6 can be easily accessed.
3. Use an Allen key to loosen the three screws 6 and
unscrew them (Fig. 8b).
4. Remove the knife holder 5 with knife 4
5. Replace or turn knife.

Adjusting the planing knives
Always disconnect the mains plug for any adjustment
work! Risk of serious injuries or damage due to inadver-
tent starting up of the device, or hazard due to electric
shock!
Decisive for a clean and even cut is the alignment of the
planing knives. This is adjusted by the Allen screw 7 in
the knife shaft.
The knives have been correctly adjusted in the factory
and normally do not need to be readjusted.
But if it becomes necessary whatever the reason (e.g.
due to previous, inadvertent misadjustment) to adjust
the position of the knives, please proceed as follows:
1. Set the receiving table 1 (Fig. 8a) to the maximum
planing depth using knurled screw 2 in order to opti-
mise the accessibility to the knife shaft.
2. Carefully turn the knife shaft 3 to a position to where
the hexagon screws 6 can be easily accessed.
3. Use an Allen key to slightly loosen the three screws 6.
4. Turn the Allen screw 7, as shown in Fig. 8c, to adjust
the position of the knives 4.
5. After successful adjustment, tighten screws 6 again
and repeat the procedure for the second knife if nec-
essary.

Lubrication

Additional lubrication for operation is normally not nec-
essary!
