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.
