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 centre.
NOTE: Edge grinding and cutting can be performed with Type
27 wheels designed and specified for this purpose; 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 guard must be used for any
wheel where surface grinding is forbidden. Cutting can also be
performed by using a Type41 wheel and a Type 1guard.
NOTE: See the Accessories Chart to select the proper guard /
accessory combination.

CAUTION: Turn unit off and unplug the tool before
making any adjustments or removing or installing
attachments or accessories.

CAUTION: BEFORE operating the tool, identify which
guard adjustment option your tool is set to.
Adjustment Options
For guard adjustment, the guard release lever
14
engages
one of the alignment holes
12
on the guard collar using a
ratcheting feature. Your grinder offers two options for this
adjustment.
• One-touch
TM
: In this position the engaging face is slanted
and will ride over to the next alignment hole when guard
is rotated in a clockwise direction (spindle facing user) but
self-locks in the anti-clockwise direction.
• Two-touch
TM
: In this position the engaging face is straight
and squared off. It will NOT ride over to the next alignment
hole unless guard release lever is pressed and held while
simultaneously rotating the guard in either a clockwise or
anti-clockwise direction (spindle facing user).
