I-Prix Cutting Wheels (4"x3) Type 42

Always handle and store wheels in a careful manner.

Always visually inspect all wheels before mounting for possible damage in transit. Vitrified wheels can be rung and should emit a clear bell-like tone if not cracked. Resinoid and rubber bonded wheels can only be checked visually.

Always check maximum operating speed established for wheel against machine speed.

Always check mounting flanges for equal and correct diameter. (Should be at least 1/3 diameter of the wheel and relieved around hole.)

Always use mounting blotters supplied with wheels.

Always be sure work rest for floor stand grinder is properly adjusted. (Center of wheel or above; no more than 1/8” away from wheel.)

Always use a machine guard covering at least one-half of the grinding wheel.

Always allow newly mounted wheels to run at operating speed, with guard in place, for at least one minute before grinding. When setting up automatic machines, make a test run with the wheel stopped.

Always wear protective goggles or other protective eye-wear when grinding.

Always turn off coolant before stopping wheel to avoid creating an out-of-balance condition.

Don’t use a wheel that has been dropped. The impact may result in breakage.

Don’t force a wheel onto the machine or alter the size of the arbor hole. Don’t use a wheel that fits the arbor too loosely. If the wheel doesn’t fit the machine, get one that does.

Don’t exceed maximum operating speed established for the wheel.

Don’t use mounting flanges which are warped, nicked, sprung, or which are not clean.

Don’t tighten the mounting nut excessively. On multiple screw mountings, 15-foot pounds per screw is usually enough.

Don’t grind on the side of the wheel unless wheel is specifically designed for that purpose.

Don’t start the machine unless the machine guard is in place.

Don’t jam work into the wheel.

Don’t stand directly in front of a grinding wheel when a grinder is started.

Don’t grind material for which the wheel is not designed.
