Operation
Start-up
Inserting the battery
Insert the charged battery (7) into the battery holder until it
is flush and you feel it engage.
Switching on/off
Make sure that you are able to press the On/Off switch
u
without releasing the handle.
To start the power tool, first press the lock-off switch (5),
then press and hold the on/off switch (6).
To switch off the power tool, release the on/off switch (6).
Note: For safety reasons, the on/off switch (6) cannot be
locked; it must remain pressed during the entire operation.
Run-out brake
An integrated run-out brake shortens the time the cutter
shafts keep running for after the power tool has been
switched off.
Setting the cutting depth
Using the knob (2), the cutting depth can be continuously
adjusted between 0–1.6 mm with the aid of the cutting
depth scale (3).
Practical advice
Planing Procedure
Set the required cutting depth and position the power tool
with the front section of the planer base plate (10) on the
workpiece.
Only bring the power tool into contact with the work-
u
piece when switched on. Otherwise there is danger of
kickback if the cutting tool jams in the workpiece.
Switch on the power tool and guide it over the surface of the
workpiece, applying uniform feed.
To achieve high-quality surfaces, apply only a low feed rate
and exert pressure on the middle of the planer base plate.
For the processing of hard materials, such as hardwood, and
also when utilising the maximum planing width, set only a
low cutting depth and reduce the planer feed as appropriate.
Excessive feed reduces the quality of the surface finish and
can lead to the chip ejector quickly becoming blocked.
Only sharp planer blades achieve good cutting performance
and make the power tool last longer.
Chamfering edges (see figure E)
The V-grooves in the front of the planer base plate enable
quick and easy chamfering of workpiece edges. Select the V-
groove that corresponds to your chamfering width. Then po-
sition the planer with the V-groove onto the edge of the
workpiece and guide it along.

Planing with the Parallel/Angle Guide (see figures F–H)
Attach the parallel guide (19) or the angle guide (23) to the
power tool with the fastening screw (22). Depending on the
application, attach the rebate depth guide (26) to the power
tool with the fastening screw (25).
Loosen the locking nut (21) and set the desired rebate width
on the scale (20). Retighten the locking nut (21).
Set the desired rebate depth accordingly using the rebate
depth guide (26).
Carry out the planing procedure several times until the de-
sired rebate depth has been achieved. Guide the planer with
sideways contact pressure.
Chamfering with angle guide
Use the angle setting (24) to
set the necessary helix angle
when chamfering grooves
and surfaces.
Maintenance and Service
Maintenance and Cleaning
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
