The coded projection (11) on the protection
guard (10) ensures that only a guard that fits the
B
machine type can be mounted.
Loosen the clamping screw (9), if necessary.
Place the protection guard (10) with coded
projection (11) into the coded groove on the
spindle collar of the machine head and rotate to
the required position (working position).
The closed side of the protection guard (10)
must always point to the operator.
Tighten clamping screw (9).

OPERATION

STARTING OPERATION

To start the power tool, push the on/off switch (3)
forward.
To lock the on/off switch (3), press the on/off
switch (3) down at the front until it engages.
To switch off the power tool, release the on/off
switch (3) or, if it is locked, briefly push down the
C2
back of the on/off switch (3) and then release it.

OPERATING INSTRUCTIONS
-
Clamp the workpiece if it does not remain
stationary due to its own weight.
-
Do not strain the machine so heavily that it
comes to a standstill.
-
Grinding and cutting discs become very hot
while working; do not touch until they have
E
cooled.
-
Pull the plug from the socket-outlet when
not using the machine. With the plug
inserted and mains voltage existing, the
power tool still has low power consumption
even when it switched off.
1. HAND GRIP AREAS
Always hold your angle grinder firmly with both
hands when operating (See E).
2. ROUGH GRINDING
The best roughing results are achieved when
C1
setting the machine at an angle of 30° to 40°.
Move the machine back and forth with moderate
pressure. In this manner, the workpiece will
not become too hot, does not discolour and no
grooves are formed.
WARNING: NEVER USE A CUTTING
DISC FOR ROUGHING.
3. CUTTING
WARNING! For cutting metal, always work
C2
with the wheel guard for cutting.
When cutting, do not press, tilt or oscillate the
machine. Work with moderate feed, adapted to
the material being cut.
1
Do not reduce the speed of running down cutting
discs by applying sideward pressure.
The direction in which the cutting is performed is
important.
The machine must always work in an up-grinding
motion. Therefore, never move the machine in
D
the other direction! Otherwise, the danger exists
of it being pushed uncontrolled out of the cut.

WORKING HINTS FOR
YOUR ANGLE GRINDER
If your power tool becomes too hot, run no load
for 2-3 minutes to cool the motor.
Never start your angle grinder with the disc/
accessory in contact with the workpiece.
Always start at no load to achieve maximum
speed then start working.
Do not force the disc to work faster, reducing the
Disc's moving speed means longer working time.
When grinding, always work with a 30° to 40°
angle between disc and workpiece. Larger
angles will cut ridges into the workpiece and
affect the surface finish. Move the angle grinder
across and back and forth over the workpiece.
When using a cutting disc, never change the
cutting angle otherwise you will stall the disc and
