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 becomes very hot during use.
• Apply only a gentle pressure to the tool. Do not exert
side pressure on the disc.
• Always install the guard and appropriate disc or
wheel. Do not use excessively worn disc or wheel.
• Be sure the inner and outer flange are
mounted correctly.
• Make sure the disc or wheel rotates in the direction of
the arrows on the accessory and the tool.
• Avoid overloading. Should the tool become hot, let it
run a few minutes under no load condition to cool the
accessory. Do not touch accessories before they have
cooled. The discs become very hot during use.
• Never work with the grinding cup without a suitable
protection guard in place.
• Do not use the power tool with a cut-off stand.
• Never use blotters together with bonded
abrasive products.
• Be aware, the wheel continues to rotate after the tools
is switched off.
Proper Hand Position (Fig. G)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a

Proper hand position requires one hand on the side handle
with the other hand on the body of the tool, as shown in
Figure G.
Paddle Switch (Fig. A)

CAUTION: Hold the side handle and body of the tool
firmly to maintain control of the tool at start up and
during use and until the wheel or accessory stops rotating.
Make sure the wheel has come to a complete stop be fore
laying the tool down.
nOTE: To reduce unexpected tool movement, do not switch
the tool on or off while under load conditions. Allow the grinder
to run up to full speed before touching the work surface. Lift the
tool from the surface before turning the tool off. Allow the tool
to stop rotating before putting it down.
1. To turn the tool on, push the lock-off lever
back of the tool, then depress the paddle switch
will run while the switch is depressed.

rotating when installing or removing wheels. Operate the
spindle lock only when the tool is turned off, unplugged from
the power supply, and has come to a complete stop.
NOTICE: To reduce the risk of damage to the tool, do
not engage the spindle lock while the tool is operating.
Damage to the tool will result and attached accessory
may spin off possibly resulting in injury.
To engage the lock, depress the spindle lock button and rotate
the spindle until you are unable to rotate the spindle further.
Surface Grinding, Sanding and Wire
Brushing

CAUTION: Always use the correct guard per the
instructions in this manual.

WARNING: Metal dust build-up. Extensive use of flap
discs in metal applications can result in the increased potential for electric shock. To reduce this risk, insert an
RCD before use and clean the ventilation slots daily by
blowing dry compressed air into the ventilation slots
inaccordance with the below maintenance instructions.
To perform work on a the surface of a workpiece:
1. Allow the tool to reach full speed before touching the tool
to the work surface.
2. Apply minimum pressure to the work surface, allowing
the tool to operate at high speed. Material removal rate is
greatest when the tool operates at high speed.
3. Maintain an appropriate angle between the tool and work

surface. Refer to the chart according to particular function.
4. Maintain contact between the edge of the wheel and the
work surface.
- If grinding, sanding with flap discs or wire brushing
move the tool continuously in a forward and back
motion to avoid creating gouges in the work surface.
- If sanding with a backing pad, move the tool constantly
in a straight line to prevent burning and swirling of
