Prior to Operation
•
Install the guard and appropriate disc or wheel. Do not
use excessively worn discs or wheels.
•
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.
•
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.
OPERATION
WARNING: Always observe the safety instructions
and applicable regulations.
WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source 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

and use a wrench on 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.
•
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 becomes very hot during use.

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.
