SLIDE ON-OFF SWITCH WITH LOCK
The tool is switched “ON” by the switch
button located at the side of the motor
housing. The switch can be locked in the
“ON” position, a convenience for long
grinding operations.
TO TURN THE TOOL “ON” without locking it,
slide the switch button forward by applying
pressure ONLY at the REAR portion of the
button. When pressure is released the switch
button will snap to “OFF” position.
TO LOCK THE SWITCH “ON”, slide the
switch button forward and press “IN” the
FRONT portion.
TO UNLOCK THE SWITCH, simply press
and release the REAR portion of the button.
Switch is spring loaded and will snap back
automatically.
Hold the tool with both hands
while starting the tool, since
torque from the motor can cause the tool to
twist.
Start the tool before applying to work and let
the tool come to full speed before contacting
the workpiece. Lift the tool from the work
before releasing the switch. DO NOT turn the
switch “ON” and “OFF” while the tool is
under load; this will greatly decrease the
switch life.
RESTART PROTECTION
The restart protection feature prevents
uncontrolled restarting of the tool after an
interruption in the power supply. To restart
the tool, turn the on/off switch to the off
position, then back to the on position.
Note: Check the function of the restart
protection feature regularly by removing the
plug from the electric outlet during operation
and then plugging it back into the outlet.
ELECTRONIC FEEDBACK CIRCUITRY
The electronic feedback system helps to
keep the no load speed virtually constant
between no-load and load conditions in order
to help maintain a uniform working
performance. The system also provides a
“soft start”, which will reduce the stresses
that occur from a high torque start.
OVERLOAD PROTECTION
Your tool is equipped with overload
protection to protect the motor. If the tool
stops during operation TURN OFF SWITCH
IMMEDIATELY and allow the motor to cool
for about 30 seconds by running at no-load.
If the overload protection stops the tool
repeatedly, excessive force is causing the
tool to overload. Don't press so hard and let
the tool do the work.
FLUSH GRINDING
For surface grinding close to the edge / wall,
slide the locking device on the dust shroud
forwards and swing the movable part of the
guard sideways (see figure 3). Lock the
locking device. To return to surface grinding
away from edges, unlock the locking device
and slide the movable part of the guard back
to the original position.
DUST EXTRACTION
This tool must only be used
with a dust extraction
system. In addition, always wear approved
dust mask.
Your tool is equipped with a dust port for
dust. To use this feature, Insert the nozzle of
a vacuum hose (accessory) into the dust port
on the tool, and then connect the opposite
end of the hose to a vacuum cleaner.
The Bosch vacuum hose comes with a
sleeve nozzle attached to a snap-in
