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 to cool the
accessory. Do not touch accessories
before they have cooled. The discs
become very hot during use.
• Do not use separate reducing
bushings or adapters to adapt large
hole abrasive wheels.
• Never use the tool without the guard
in place.
• The tool is not designed to be used
with a grinding cup.
• 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.
