Guards

CAUTION: Guards must be used with all grinding
wheels, cutting wheels, sanding flap discs, wire
brushes, and wire wheels. The tool may be used
without a guard only when sanding with conventional
sanding discs. Refer to Figure A to see guards provided
with the unit. Some applications may require
purchasing the correct guard from your local dealer or
authorized service center.
nOTE: Edge grinding and cutting can be performed with
Type 27 wheels designed and specified for this purpose; 1/4"
(6.35 mm) thick wheels are designed for surface grinding
while thinner Type 27 wheels need to be examined for
the manufacturer's label to see if they can be used for
surface grinding or only edge grinding/cutting. A Type 1/41
guard must be used for any wheel where surface grinding
is forbidden. Cutting can also be performed by using a
Type 1/41 wheel and a Type 1/41 guard.
nOTE: See the Accessories Chart to select the proper guard/
accessory combination.

power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start‑up can cause injury.

WARNING: Accessories must be rated for at least
the speed recom mended on the tool warning label.
Wheels and other accessories running over their
rated accessory speed may fly apart and cause injury.
Threaded accessories must have a 5/8"‑11 hub. Every
unthreaded accessory must have a 7/8" (22 mm) arbor
hole. If it does not, it may have been designed for a
circular saw and should not be used. Use only the
accessories shown in the Accessories Chart of this
manual. Accessory ratings must always be above tool
speed as shown on tool nameplate.

WARNING: Handle and store all abrasive wheels
carefully to prevent damage from thermal shock, heat,
mechanical damage, etc. Store in a dry protected area
free from high humidity, freezing temperatures or
extreme temperature changes.

nOTE: If the wheel spins after the clamp nut is tightened,
check the orientation of the threaded clamp nut. If a thin
wheel is installed with the pilot on the clamp nut against the
wheel, it will spin because the height of the pilot prevents
the clamp nut from holding the wheel.
