face or the planer blade. While planing, the park rest 29 is tilt-
ed upwards thus enabling full contact of the rear part of the
planer base plate 8.
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, press the On/Off switch 5 and keep it
pressed.
To lock the pressed On/Off switch 5, press the lock-on button
4.
To switch off the machine, release the On/Off switch 5 or
when it is locked with the lock-on button 4, briefly press the
On/Off switch 5 and then release it.
Working Advice
 Before any work on the machine itself, pull the mains
plug.
Planing (see figure N)
Set the required planing depth and place the front part of the
planer base plate 8 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.
The integrated park rest 29 also allows for continued planing
at any given location on the workpiece after an interruption:
– With the park rest folded down, place the machine on the
location of the workpiece where the planing is to be contin-
ued.
– Switch on the machine.
– Apply the supporting pressure onto the front part of the
planer base plate and slowly push the machine forward
(). This tilts the park rest upward () so that the rear
part of the planer base plate faces on the workpiece again.
– Guide the machine over the surface to be planed () with
even feed.
Beveling Edges (see figure O)
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 figures K – M)
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.

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.
Ensure easy operation of the park rest 29 and clean it regular-
ly.
When the carbon brushes wear below acceptable service tol-
erances, the machine will automatically cut out. The machine
must be sent to customer service for maintenance (for ad-
dress, see the "After-sales Service and Application Service"
section).
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.
Replacing the Drive Belt (see figures P – Q)
Unscrew screw 6 and take off the belt cover 7. Remove the
worn drive belt 30.
Before assembling a new drive belt 30, clean both pulleys 31
and 32.
Place the new drive belt 30 on the small pulley 32 first and
then work the drive belt 30 onto the large pulley 31 by hand
while rotating it.
