Assembly
 Before any work on the machine itself, pull the mains
plug.
– Use suitable screws to fix the power tool to the workbench /
worktop at the 4 holes 7 provided.
Mounting the Spark Guard/Workpiece Support
(see figures A–D)
 Use the machine only with the spark guard 10. Sparks
being expelled can injure your eyes or set objects in the vi-
cinity on fire.
– Mount the holder for the spark guard 9 with the two
screws.
– Screw the spark guard 10 to the holder of the spark guard
9.
– Mount the workpiece support 11 as shown in the figure.
 Do not interchange the right and left workpiece sup-
port 11. Otherwise, the clearance between workpiece
support 11 and grinding wheel will be too large. When the
clearance is larger, you are not sufficiently protected
against sparking. The workpiece can be drawn in by the ro-
tational motion of the grinding wheel and lead to injuries.
 Regularly check the clearance between the workpiece
support 11 as well as the holder of the spark guard 9 to
the grinding wheel, and readjust as required. The clear-
ance to the grinding wheel may not exceed 2 mm. When
the clearance is larger, you are not sufficiently protected

against sparking. The workpiece can be drawn in by the ro-
tational motion of the grinding wheel and lead to injuries.
Replace the grinding wheel when the holder of the spark
guard 9 can no longer be adjusted to the required clearance of
2 mm (max.) to the grinding wheel.
Changing a Grinding Wheel
 Before any work on the machine itself, pull the mains
plug.
 The rated speed of the accessory must be at least equal
to the maximum speed marked on the power tool. Ac-
cessories running faster than their rated speed can break
and fly apart.
Replace the grinding wheel as soon as its residual material
reaches a thickness of 10 mm.
– Loosen the 3 screws of cover 1 and remove cover 1. Hold
the grinding wheel wearing protective gloves and un-
screw the clamping nut 2 from the grinder spindle 5.
Note: The grinder spindle 5 on the left side of the machine has
a left-hand thread.
– Remove the clamping flange 3 and the grinding wheel from
the grinder spindle 5.
– The new grinding wheel is mounted in reverse order. Place
the cover 1 firmly onto the housing and tighten with the 3
screws.
Dress used and out-of-centre grinding wheels with a whet-
stone (accessory) before continuing to use them.
