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 battery pack
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can cause injury.

WARNING:
• Ensure all materials to be ground or cut are secured
in place.
• Secure and support the workpiece. 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 movement of the
workpiece and loss of control. Movement of the
workpiece or loss of control may create a hazard and
cause personal injury.
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.
• Apply only a gentle pressure to the tool. Do not exert
side pressure on the disc.
• Always wear regular working gloves while operating
this tool.
• The gear case becomes very hot during use.
• 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.
