various dust extractors at the end of these operating instruc-
tions.
The dust extractor must be suitable for the material being
worked.
When extracting dry dust or dust that is especially detri-
mental to health or carcinogenic, use a special dust ex-
tractor.
Self-Generated Dust Extraction (see figure G)
A chip/dust bag (20) can be used for smaller jobs. Insert the
dust bag nozzle of the chip/dust bag firmly into the chip
ejector (3). Empty the chip/dust bag (20) at regular inter-
vals to maintain optimum dust collection.
Selectable chip ejector
Using the changeover lever (8), the chip ejector can be (3)
adjusted to the right or left. Push the changeover lever (8) all
the way towards the end position until it clicks into place.
The selected chip ejector direction is indicated by an arrow
symbol on the changeover lever (8).
Operation
Start-up
Setting the cutting depth
Using the knob (2), the cutting depth can be adjusted in
stages between 0–2.6 mm with the aid of the cutting depth
scale (1) (scale division = 0.1 mm).
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 (4),
then press and hold the on/off switch (5).
To switch off the power tool, release the on/off switch (5).
Note: For safety reasons, the on/off switch (5) cannot be
locked; it must remain pressed during the entire operation.
Practical advice
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.
Parking rest (see figure H)
The parking rest (23) makes it possible to put down the
power tool directly after working, without any danger of
damaging the workpiece or planer blade. During the work
process, the parking rest (23) is highly pivoted and the rear
section of the planer base plate (9) is released.
Note: The parking rest (23) must not be removed.
Planing Procedure (see figure H)
Set the required cutting depth and position the power tool
with the front section of the planer base plate (9) on the
workpiece.

When positioning the power tool on a workpiece, only apply
weight at the front and do not tilt the planer backwards. Oth-
erwise this could result in damage to the workpiece. If the
end of the workpiece is reached, shift the holding weight
backwards so that the planer does not tilt forwards and dam-
age the workpiece. It is best to test planing on sample
pieces.
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.
The integrated parking rest (23) also enables a continuation
of the planing procedure following interruption at any point
on the workpiece:
– Place the power tool – with parking rest folded down –
onto the area of the workpiece that you will continue to
work on.
– Switch the power tool on.
– Shift the contact pressure onto the front of the planer
base plate and slowly slide the power tool forward (➊). In
doing so, the parking rest will swivel upwards and out of
the way (➋), meaning that the rear section of the planer
base plate is in contact with the workpiece again.
– Guide the power tool over the surface of the workpiece,
applying uniform feed (➌).
Chamfering edges (see figure I)
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 Guide (see figures D–F)
Fit the parallel guide (16) to the power tool using the fasten-
ing screw (18). Depending on the application, attach the re-
bate depth guide (22) (accessory) to the power tool with the
fastening screw (21).
Loosen the fastening screw (17) and set the required rebate
width. Retighten the fastening screw (17).
