Switching On and Off
To switch on the machine, push the On/Off switch 2 forward
and press it down at the front to lock on.
To switch off the machine, press down the On/Off switch 2 at
the rear so that the switch springs back to the off position.
To save energy, only switch the power tool on when using it.

Working Advice

 When working with the machine, always hold it firmly
with both hands and provide for a secure stance. The
power tool is guided more secure with both hands.
 Keep your hands away from the cutting area and the
cutting disc.
While working, hold handle 1 with one hand and auxiliary han-
dle 15 with the other hand.
 Apply the machine to the workpiece only when
switched on. Otherwise there is danger of kickback when
the cutting tool jams in the workpiece.
Carry out the routing process applying uniform feed.
Establishing the Cutting Position
The vertical centre mark of cut 11 on the angle and height
stop indicates the centre of the cut (vertical to the cutting
disc). The maximum width of the cut is indicated by the two
marks 10 on the adjustable height stop 9.
For positioning of the height, the horizontal centre mark of cut
6 on the base plate, which indicates the horizontal centre of
the cutting disc, is helpful.
The direction-of-rotation arrow 13 on the housing of the pow-
er tool indicates the rotation direction of the cutting disc.
Cutting Groove Joints
Examples for the following groove joints are shown on the
graphic pages:
– Corner joints: With the angle stop, see figure C; with the
adjustable height stop, see figure D
– Mitre joints: With the angle stop, see figure E; with the ad-
justable height stop, see figure F
– Longitudinal and lateral joints: With the angle stop, see
figure G; with the adjustable height stop, see figure H
– Frame joints: See figure I
– Centre wall joints: See figure J

Use the largest possible biscuit for a solid wood joint. Bosch
offers appropriate biscuits in the accessories program (see
accessories page at the end of the operating instructions).
Cutting Thin Workpieces (see figure K)
For cutting workpieces with a thickness below 16 mm, place
the attachment plate 16 on the angle stop 17. This ensures
that the groove is not cut too close to the upper surface of the
workpiece. When calculating the horizontal cutting position,
consider the 4 mm thickness of the attachment plate.
Also use the attachment plate 16 for mitre joints in thin work-
pieces so that the groove is not cut too deep.
Cutting Narrow Workpieces
If possible, use the adjustable height stop 9 when cutting nar-
row workpieces. Pay attention that the marks for the maxi-
mum cutting disc width 10 on the height stop are within the
workpiece.

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.
Clean and grease the guides as necessary. Use exclusively
non-gumming oil for this (e.g., sewing machine oil).
Re-tensioning Clamping Levers
The tensioning force of the clamping levers 3 and 12 can be
readjusted, if required. For this, loosen and then screw off the
clamping lever. Screw on the clamping lever again displaced
by at least 30° in anticlockwise direction.
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.
