Clean the chip ejector 1 regularly. Use a suitable
tool (e.g., a piece of wood, compressed air,
etc.) to clean a clogged chip ejector.
Do not reach into the saw dust ejector with
your hands. They could be injured by rotat-
ing parts.
To ensure optimum extraction of dust/chips, al-
ways work with external dust extraction or a
chip/dust bag.
External Dust Extraction (see figure C)
An extraction hose (Ø 35 mm) 17 (accessory),
can be attached on either side of the chip ejec-
tor.
Connect the vacuum hose 17 to a vacuum clean-
er (accessory). 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 ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
Integrated Dust Extraction (see figure C)
A chip/dust bag (accessory) 18 can be used for
smaller jobs. Insert the sleeve of the chip/dust
bag firmly into the chip ejector 1. Empty the
chip/dust bag 18 at regulary intervals to main-
tain 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 se-
lector lever 4 until it engages in the end posi-
tion. The selected ejection direction is indicated
by an arrow symbol on the selector lever 4.

Starting Operation

Inserting the Battery
Use only original Bosch O-pack batteries
with the voltage given on the type plate of
your machine. The use of other batteries can
lead to injuries and danger of fire.
Insert the charged battery 7 into the handle until
it can be felt to engage and faces flush against
the handle.
Switching On and Off
To start the machine, first push the lock-off but-
ton 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.
Run-on Brake
An integrated run-on brake reduces after-run-
ning of the blade shaft after switching off the
machine.

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 dan-
ger 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. hard-
wood) as well as when utilising the maximum
planer width, set only low planing depths and
reduce planer feed, as required.
