COMBINATION OF APPLICATIONS AND
ACCESSORIES
Optional accessory
CAUTION:
Using the tool with incorrect guards can cause risks as follows.
• When using a cut-off wheel guard for facial grinding, the wheel guard may interfere with the work-
piece causing poor control.
• When using a grinding wheel guard for cutting-off operations with bonded abrasive wheels and dia-
mond wheels, there is an increased risk of exposure to rotating wheels, emitted sparks and particles,
as well as exposure to wheel fragments in the event of wheel burst.
• When using a cut-off wheel guard or grinding wheel guard for facial operations with cup-type dia-
mond wheels, the wheel guard may interfere with the workpiece causing poor control.
When using a cut-off wheel guard or grinding wheel guard with a wheel-type wire brush with a thick-
•
ness greater than the maximum thickness as specified in "SPECIFICATIONS", the wires may catch on
the guard leading to breaking of wires.
Use of dust collecting wheel guards for cutting-off and facial operations in concrete or masonry
•
reduces a risk of exposure to dust.
• When using dual purpose (combined grinding and cutting-off abrasive) flange mounted wheels, only
use a cut-off wheel guard.
