Grinding Operations
Wheel Guard Installation
Warning:
The wheel guard must be attached when using disc-
grinding wheels. Always keep wheel guard between you
and your work while grinding.
• To attach the wheel guard, disconnect tool from power source. Be
sure that the wheel guard is in place for grinding. Place the
backing flange and grinding wheel on the spindle. Thread on the
lock nut and tighten nut using the supplied lock nut wrench.
• To secure wheels 1/8" thick or less, the hub on the lock nut should
face outward. To secure wheels thicker than 1/8", the hub on the
lock nut should face inward.
Selecting Grinding Wheels
Warning
: Before using a grinding wheel, be certain that its
maximum safe operating speed is equal or greater to that
of the grinder. Do not exceed the recommended wheel
diameter.
Disc Grinding Wheels
• Grinding wheels should be carefully selected in order to use the
grinder most efficiently. Wheels vary in type of abrasive, bond,
hardness, grit size and structure. The correct type of wheel to use
is determined by the job.
Grinding Operations
• Use disc grinding wheels for fast grinding of structural steel,
heavy weld beads, steel casting, stainless steel and other ferrous
metals.
