Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool's
operation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools. Inspect tool cords and plugs
periodically and, if damaged, have them repaired by a
qualiied person.
f) Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc., in
accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations diferent
from those intended could result in a hazardous situation.
5) SERVICE
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.

USE
• Mounting of spark guard 7
- loosen screw B1 (do not remove it)
! regularly check the distance between spark
guard A and the grinding wheel (max. 2 mm) and
re-adjust, if necessary
- replace the grinding wheel, if it is worn down to the
point where spark guard A can no longer be adjusted
to the maximum distance of 2 mm
• Mounting of tool rest 8
! regularly check the distance between tool rest C
and the grinding wheel (max. 2 mm) and
re-adjust, if necessary
• Mounting tool on working surface 9
! for safe handling always mount tool on a flat and
stable working surface (e.g. workbench)
- use 4 mounting holes D for attaching the tool with
suitable screws to the working surface
- you may also clamp the tool to the working surface
with commercially available screw clamps
! remove 4 rubber supports E before mounting tool
on working surface
• On/of
