 Do not reach into the saw dust ejector with your hands.
They could be injured by rotating parts.
To ensure optimum extraction of dust/chips, always work
with external dust extraction or a chip/dust bag.
External Dust Extraction (see figure E)
An extraction hose (Ø 35 mm) 19 (accessory), can be at-
tached on either side of the chip ejector.
Connect the vacuum hose 19 to a vacuum cleaner (accesso-
ry). An overview for connecting to various vacuum cleaners
can be found at the end of this manual.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Integrated Dust Extraction (see figure E)
A chip/dust bag (accessory) 20 can be used for smaller jobs.
Insert the sleeve of the chip/dust bag firmly into the chip ejec-
tor 1. Empty the chip/dust bag 20 at regulary intervals to
maintain optimum dust collection.
Choice of Chip Ejector Side
With the selector lever 4, the chip ejector 1 can be switched
to right or left. Always press the selector lever 4 until it engag-
es in the end position. The selected ejection direction is indi-
cated by an arrow symbol on the selector lever 4.
Operation

Operating Modes

Adjusting the Planing Depth
With the adjustment knob 2, the planing depth can be adjust-
ed variably from 0–1.6 mm using the planing depth scale 3.

Starting Operation

Inserting the battery
Insert the charged battery 7 into the battery port until it can
be felt to engage and is seated flush.
Switching On and Off
To start the machine, first push the lock-off button for the
On/Off switch 5 and then press the On/Off switch 6 and keep
it pressed.
To switch off the machine, 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.
To save energy, only switch the power tool on when using it.
Run-on Brake
An integrated run-on brake reduces after-running of the blade
shaft after switching off the machine.
Protection Against Deep Discharging
The lithium-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.

Working Advice
Planing
Set the required planing depth and place the front part of the
planer base plate 10 against the workpiece.
 Apply the machine to the workpiece only when
switched on. Otherwise there is danger of kickback when
the cutting tool jams in the workpiece.
Switch the machine on and guide the machine with even feed
over the surface to be planed.
To achieve high-grade surfaces, work only with low feed and
apply pressure on the centre of the planer base plate.
When machining hard materials (e.g. hardwood) as well as
when utilising the maximum planer width, set only low planing
depths and reduce planer feed, as required.
Excessive feed reduces the surface quality and can lead to
rapid clogging of the chip ejector.
Only sharp blades achieve good cutting capacity and give the
machine longer life.
Beveling Edges (see figure F)
The V-grooves in the front planer base plate allow quick and
easy beveling of workpiece edges. Depending on required
bevel width, use the corresponding V-groove. For this, place
the planer with the V-groove onto the edge of the workpiece
and guide it along the edge.

Planing with Parallel/Beveling Guide (see figure G–I)
Mount the parallel guide 21 or beveling guide 25 to the ma-
chine using the corresponding fastening bolt 24. Depending
on the application, mount the rebating depth stop 28 with fas-
tening bolt 27 to the machine.
Loosen the locking nut 23 and adjust the requested rebating
width on the scale 22. Tighten the locking nut 23 again.
Adjust the requested rebating depth accordingly with the re-
bating depth stop 28.
Carry out the planing procedure several times until the re-
quested rebating depth is reached. Guide the planer applying
sideward supporting pressure.
Beveling with the Beveling Guide
When beveling rebates and
surfaces, adjust the required
slope angle with the angle ad-
justment 26.
