Adjusting Wheel Guard
Note: Before any work on
the machine itself, remove
the battery pack. For work
with grinding or cutting
discs, the protection guard
must be mounted. Use
the correct type of disc
for your application. If the
power tool is intended
to perform cutting off
operations, a guard specific
for this operation must be
fitted.
The coded projection on the
wheel guard ensures that only
a guard that fits the machine
type can be mounted.
Open the clamping lever (13).
Place the wheel guard with
coded projection into the
coded groove on the spindle of
the machine head and rotate to
the required position (working
position).
To fasten the wheel guard,
close the clamping lever (13).
The closed side of the
wheel guard must always
point to the operator.

WORKING HINTS FOR YOUR
ANGLE GRINDER
1. Always start at no load to achieve maximum
speed then start working.
2. Do not force the disc to work faster, reducing the
Disc's moving speed means longer working time.
3. Always work with a 15-30 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.
4. When using a cutting disc never change the
cutting angle otherwise you will stall the disc
