When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Integrated Dust Extraction (see figure C)
A chip/dust bag (accessory) 16 can be used for smaller jobs.
Insert the sleeve of the chip/dust bag firmly into the chip ejec-
tor 3. Empty the chip/dust bag 16 at regulary intervals to
maintain optimum dust collection.
Operation
Operating Modes
Adjusting the Planing Depth
With the adjustment knob 2, the planing depth can be adjust-
ed variably from 1–1,5 mm using the planing depth scale 1
(scale graduation = 0.25 mm).
Park Position
After the working procedure, set the depth adjustment knob
2 to position P (park position). This retracts the planer blade,
allowing the power tool to be placed down without the danger
of causing damage to the workpiece or the planer blade.
Starting Operation
 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Switching On and Off
 To save energy, only switch the power tool on when
using it.
To start the machine, first push the lock-off button for the
On/Off switch 5 and then press the On/Off switch 4 and keep
it pressed.
To switch off the machine, release the On/Off switch 4.
Note: For safety reasons, the On/Off switch 4 cannot be
locked; it must remain pressed during the entire operation.
Working Advice
Planing
Set the required planing depth and place the front part of the
planer base plate 6 against the workpiece.
 Before any work on the machine itself, pull the mains
plug from the socket outlet.
 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 G)
The V-groove 7 in the front planer base plate allows quick and
easy beveling of workpiece edges. 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 figures D–F)
Mount the parallel guide 17 or beveling guide 21 to the ma-
chine using the corresponding fastening bolt 20. Depending
on the application, mount the rebating depth stop 24 with fas-
tening bolt 23 to the machine.
Loosen the locking nut 19 and adjust the requested rebating
width on the scale 18. Tighten the locking nut 19 again.
Adjust the requested rebating depth accordingly with the re-
bating depth stop 24.
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 22.

Maintenance and Service

Maintenance and Cleaning
 Before any work on the machine itself, pull the mains
plug.
 For safe and proper working, always keep the machine
and ventilation slots clean.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
