Replacing the Planer Cutter
Blade (Figure A)
Before all work on the machine itself,
pull the mains plug.
Wear protective gloves for inserting
and changing the planer cutter
blades.
Removing the Planer Cutter Blades
– For reversing or inserting the planer cutter blades,
bring the cutter head 16 to the appropriate posi-
tion (see Figure).
– Loosen the screws 13 with the Allen key provided
with the machine.
– Fold away the rebate protector 11.
– Turn the cutter head 16 somewhat and slide the
cutter blade holder 14 to the side out of the cutter
head with a piece of wood.
– Pull the cuter blade 10 from the cutter blade hol-
der 14.
– It is best to clean heavily gummed cutter blades
with alcohol or paraffin.
Always replace both planer cutter blades.
Inserting the Planer Cutter Blades
Before reinserting a new or a reversed planer cutter
blade 10, remove dirt from it as well as from the cut-
ter blade seat.
Care is to be taken when mounting that the cutter
blade holder 14 is seated properly in the holder
guide of the cutter head 16.
Note: To be able to rebate flawlessly, it is important
that the planer cutter blades are aligned with the
side edge of the rear planer base plate. This can be
checked with a straight piece of wood (ruler), for ex-
ample (see Figure).
Align the cutter blade 10/cutter blade holder 14
accordingly and firmly tighten the screws 13.
Before returning to operation, the cutter
blades are to be checked for firm seating
and flawless running.
Adjusting the Planer Blades
Before starting operation for the first time or in case
of irregular material removal, the height of the pla-
ner blades must be adjusted.
– Set the planing depth to 0 mm.
– Turn the blade shaft until the planer blade is at the
highest position.
– Position a large-surface, straight piece of wood
onto the rear of the base plate and the edge of the
blade.
– Turn both adjusting screws 15 until the planer
blade 10 faces flush against the surface of the
wood piece.
Turn the blade shaft and repeat the procedure for
the second planer blade.

Initial operation

Always use the correct supply voltage: The power
supply voltage must match the information quoted
on the tool identification plate.
