SAFETY
Additional Safety Instructions for Grinders
1. EYE PROTECTION. Grinding causes small particles to become airborne at a high rate of speed.
ALWAYS wear safety glasses when using this machine.
2. MOUNTING TO BENCH/STAND. An unsecured grinder may become dangerously out of control dur
-
ing operation. Make sure grinder is FIRMLY secured to a bench/stand before use.
3. WHEEL SPEED RATING. Wheels operated at a faster speed than rated for may break or fly apart.
Before mounting a new wheel, be sure the wheel RPM rating is equal or higher than the speed of
the grinder.
4. WHEEL FLANGES. Only use the flanges included with the grinder when mounting wheels. Other
flanges may not properly secure the wheel and cause an accident.
5. RING TEST. Perform a “ring test” on grinding wheels before installation to ensure that they are
safe to use. A wheel that does not pass the ring test may break or fly apart during operation.
6. STARTING GRINDER. If a wheel IS damaged, it will usually fly apart shortly after start-up. To
protect yourself, always stand to the side of the grinder when turning it
ON, allow it to gain full
speed and wait for at least 1 minute before standing in front of it.
7. LUNG PROTECTION. Grinding produces hazardous dust, which may cause long-term respiratory
problems if breathed. Always wear a NIOSH approved dust mask or respirator when grinding.
8. SIDE GRINDING. Grinding on the side of wheels can cause them to break and fly apart—unless the
wheel is rated for side grinding.
9. TOP GRINDING. Grinding on the top of wheels greatly increases the risk of workpiece kickback.
Always grind on the downward part of the wheel.
10. HAND/WHEEL CONTACT. Grinding wheels have the capability of removing a lot of skin fast. Keep
a firm grip on the workpiece and position your hands a safe distance away when grinding. Avoid
wearing gloves as they may get caught in the grinding wheel and cause even more serious entan
-
glement injuries.
11. TOOL REST POSITION. If the tool rest is too far away from the wheel, the workpiece may be
pulled down, causing loss of control and pulling your hand into the grinding wheel. Keep the tool
rest within
1
⁄8" from the wheel when operating.
USE this and other machinery with caution
and respect. Always consider safety first,
as it applies to your individual working
conditions. No list of safety guidelines can
be complete—every shop environment is
different. Failure to follow guidelines could
result in serious personal injury, damage
to equipment or poor work results.
