Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine.
Switching On and Off
Before starting the machine, place the pow-
er tool in such a manner on both rear chaser
rollers 3 that the diamond cutting discs do
not touch the workpiece. Otherwise, the
diamond cutting discs can touch the work-
piece, resulting in possible loss of control
over the power tool when switching on.
To start the power tool, press the On/Off switch
1 forward and then down.
To lock-on the pressed On/Off switch 1, push
the On/Off switch 1 further forward.
To switch off the power tool, release the On/Off
switch 1, or when it is locked, briefly press the
On/Off switch 1 and then release it.
Switch Version without Lock-on
(country-specific):
To start the power tool, press the On/Off switch
1 forward and then down.
To switch off the machine, release the On/Off
switch 1.
Never set down a coasting machine on the
chaser rollers 3, but always aside, so that
the diamond cutting discs can rotate freely
and do not face toward your body.
Check the diamond cutting discs before
use. The diamond cutting disc(s) must be
mounted properly and be able to rotate
freely. Carry out a test run for at least one
minute without any load. Do not use dia-
mond cutting discs that are damaged, out-
of-balance, or vibrate. Damaged diamond
cutting discs can rupture and lead to injuries.
Bosch Power Tools
Reduced starting current
The electronic reduced starting current limits
the power consumption when switching the tool
on and enables operation from a 13 ampere
fuse.
Overload Protection
When overloaded, the motor comes to a stop.
Relieve the load on the machine immediately
and allow to cool down for approx. 30 seconds
at the highest no-load speed.
Restarting Protection
The restarting protection feature prevents un-
controlled restarting of the machine after an in-
terruption in the power supply.
To restart the operation, switch the On/Off
switch 1 to the Off position and start the ma-
chine again.
Note: Check the function of the restarting pro-
tection feature regularly by having the mains
plug pulled during operation and plugged in
again afterwards.

Working Advice

Exercise caution when cutting slots in
structural walls; see Section "Information
on Structures ".
Do not strain the machine so heavily that it
comes to a standstill.
Clamp the workpiece if it does not remain
stationary due to its own weight.
The machine may only be used for dry cut-
ting.
Always guide the machine with both han-
dles. Do not guide or carry the machine by
the elbow.
– Adjust the cutting depth, see section "Pre-se-
lecting the Cutting Depth". To compensate
inaccuracies that occur when breaking away
the fin, the cutting depth must be set approx.
3 mm deeper than the requested slot depth.
