ASSEMBLY AND ADJUSTMENTS
WARNING: To reduce the risk of
injury, turn unit off and disconnect
machine from power source before
installing and removing accessories,
before adjusting or changing
set-ups or when making repairs.

WARNING: Accessories must be rated
at least equal to the maximum speed
marked on the tool. Accessories running
faster than their rated speed can break
and fly apart.
WARNING: Accessories must be within
the capacity rating marked on the tool.
Incorrectly sized accessories cannot be
adequately controlled.
WARNING: Do not use accessories
with a mandrel length exceeding 40
mm. Ensure that the exposed mandrel
length is no more than 10 mm after
inserting accessory into collet.
WARNING: Never tighten the collet nut
without an accessory in the collet.
1. Hold the spindle (b) using the 13mm wrench (f)
provided.
2. Loosen the collet nut (c) with the 17mm
wrench(g) by turning it counterclockwise.
3. Insert the shank of the accessory (minimum
20mm) into the collet.
4. Securely tighten the collet nut (c) using the
spanner provided.
NOTE: The shank overhang, amount that sticks

10mm. Refer to figure 4.
OPERATION
Instructions for Use
WARNING: Always observe the safety
instructions and applicable regulations.
WARNING: To reduce the risk of
injury, turn unit off and disconnect
machine from power source before
installing and removing accessories,
before adjusting or changing
set-ups or when making repairs.
Before reconnecting the tool, depress
and release the trigger switch to ensure
that the tool is off. An accidental start-
up can cause injury.
WARNING:
• Ensure all materials to be ground or
cut are secured in place.
• Use clamps or a vice to hold
and support the workpiece to a
stable platform. It is important to
clamp and support the workpiece
securely to prevent the movement
of the workpiece and loss of control.
Movement of the workpiece or loss
of control may create a hazard and
cause personal injury.
• Secure the workpiece. A workpiece
clamped with clamping devices or in
a vice is held more secure than by
hand.
• Support panels or any oversized
workpiece to minimize the risk of
wheel pinching and kickback. Large
workpieces tend to sag under their
own weight. Supports must be
placed under the workpiece near the
line of cut and near the edge of the
workpiece on both sides of the wheel.
• Always wear regular working gloves
while operating this tool.
• The gear case becomes very hot
during use.
• Apply only a gentle pressure to the
tool. Do not exert side pressure on the
disc.
• Avoid overloading. Should the tool
become hot, let it run a few minutes
under no load condition.
• The best grinding results are achieved
when setting the machine at an angle
of 90°. 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: Grasp tool firmly with both
hands to maintain control of the tool at
start up and during use and until the
wheel or accessory stops rotating. Make
