Transport (see figure X)
Before transporting the power tool, the following steps must
be carried out:
– Loosen the locking screw 6 if tightened. Pull the tool arm
completely to the front and tighten the locking screw

backward and that the adjusting screw 40 fits through the
recess without touching the depth stop when moving the
tool arm.
– Bring the machine into the transport position.
– Remove all accessories that cannot be mounted firmly to
the power tool.
If possible, place unused saw blades in an enclosed con-
tainer for transport.
– Wind up the mains cable and tie it together with Velcro
strap 67.
– Carry the machine by the transport handle 10 or hold it by
the recessed handles 29 on the sides of the saw table.
 The power tool should always be carried by two per-
sons in order to avoid back injuries.
 When transporting the power tool, use only the trans-
port devices and never use the protective devices.

Maintenance and Service

Maintenance and Cleaning

 Before any work on the machine itself, pull the mains
plug.
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.
Cleaning
For safe and proper working, always keep the power tool and
its ventilation slots clean.
The retracting blade guard must always be able to move freely
and retract automatically. Therefore, always keep the area
around the retracting blade guard clean.
Remove dust and chips after each working procedure by
blowing out with compressed air or with a brush.
Clean the roller 16 regularly.
