Prior to Operation

• Install the guard and appropriate disc or wheel.
Do not use excessively worn discs or wheels.
• Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for
cracks, tear or excess wear, wire brush for loose
or cracked wires. If power tool or accessory
is dropped, inspect for damage or install an
undamaged accessory. After inspecting and
installing an accessory, position yourself and
bystanders away from the plane of the rotating
accessory and run the power tool at maximum
no-load speed for one minute. Damaged
accessories will normally break apart during this
test time.
• Be sure the inner and outer flange are mounted
correctly. Follow the instructions given in the
Grinding and Cutting Accessory Chart.
• Make sure the disc or wheel rotates in the
direction of the arrows on the accessory and
the tool.
OPERATION
Instructions for Use
WARNING: Always observe the safety
instructions and applicable regulations.
WARNING: To reduce the risk
of serious personal injury, turn
tool off and disconnect tool from
power source before making any
adjustments or removing/installing
attachments or accessories. Before
reconnecting the tool, depress and
release the trigger switch to ensure that
the tool is off.
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.
