without the use of the spacer and threaded flange.
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.
