Put the work in a vise or clamp it securely. Use a face mask
over the nose and mouth if the operation raises dust. Treat
the wheel with respect. Do not jam the wheel into the work or

start-up can cause injury.
WARNING: To reduce the risk of serious personal injury,

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
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 sure the wheel
has come to a complete stop be fore laying the tool down.
