Bosch Professional GKF 12V-8 Original Instructions Manual page 10

10 | English
Push and hold the routing depth coarse adjustment but-
ton (8). Move the drive unit up or down and adjust the rout-
ing depth to approximately the required position. Release
the (8) button.
Use the thumbwheel (10) to set the exact routing depth re-
quired. Each revolution of the thumbwheel alters the routing
depth by 1 mm.
Turn the locking wheel (14) clockwise approximately half a
revolution to lock the depth-of-cut adjuster.
Check the routing depth you have set by carrying out a prac-
tical test and correct it if required.
If you want to keep the tool at the routing depth you have
set, you can screw the fixing screw (11) into the routing
depth fine adjustment thumbwheel (10).
Starting Operation
Inserting the Battery
Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Insert the charged battery (1) into the battery holder until it
is flush and you feel it engage.
Switching On and Off
To switch on the power tool, slide the on/off switch (5)
downwards so that I appears on the switch.
To switch off the power tool, slide the on/off switch (5) up-
wards so that 0 appears on the switch.
Working Advice
Protect router bits against shock and impact.
u
Routing direction and routing process (see figures F–G)
Routing must always be carried out with the work-
u
piece being moved against the direction in which the
router bit (17) is turning (up cut). If the workpiece is
moved in the same direction as the router bit is turning
(down cut), the power tool may be pulled out of your
hands.
Note: Be aware that the router bit (17) always protrudes
slightly from the base plate (12). Do not damage the tem-
plate or the workpiece.
Set the routing depth you want.
Switch on the power tool and guide it to the point you want
to machine.
Carry out the routing process with a uniform feed.
Switch off the power tool after routing.
Do not put the power tool down before the router bit
u
has come to a complete stop. Application tools that are
still running can cause injuries.
Edge or profile routing (see figure H)
For edge and profile routing without a parallel guide, the
router bit must be fitted with a pilot pin or a ball bearing.
While it is switched on, guide the power tool towards the
workpiece from the side until the pilot pin or the ball bearing
of the router bit is touching the side of the workpiece edge
that you want to machine.

Guide the power tool along the workpiece edge. Pay atten-
tion that the router is positioned perpendicularly. Too much
pressure can damage the edge of the workpiece.
The following maximum workpiece dimensions apply for
edge and profile milling operations:
Material
Hardwood
Softwood
Plastic
MDF sheets
Plywood sheets
Temperature monitoring/overload protection indicator
The red LED indicator (3) helps you to protect the battery
against overheating and the motor against overload.
If the LED indicator (3) is lit up permanently in red, the
temperature of the battery is too high and the power tool
switches off automatically.
– Switch the power tool off.
– Allow the battery to cool down before you carry on work-
ing.
If the LED indicator (3) is flashing red, then the power tool
is blocked and will switch off automatically.
Pull the power tool out of the workpiece.
The power tool will continue to work as soon as the blockage
is rectified.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
Maintenance and Service
Maintenance and Cleaning
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
Clean the power tool with a vacuum cleaner, paint brush or
hand brush after use. Ensure that the guide columns are free
of wood dust. Apply a drop of lubricant to the smooth guide
column (19) (see figure I).
