Additional Safety Instructions for Grinders
7. LUNG PROTECTION. Grinding produces
hazardous dust, which may cause long-
term respiratory problems. Always wear a
NIOSH approved dust mask or respirator
when grinding.
8. SIDE GRINDING. Grinding on the side of
wheels can cause the 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 can remove 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 entanglement
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 con-
trol and pulling your hand into the grinding
wheel. Keep the tool rest within
1 ⁄
8
" from the
wheel when operating.
12. CRACKED WHEEL. Cracked wheels
may break and fly apart during operation.
Replace cracked wheels immediately!
1. EYE PROTECTION. Grinding ejects small
particles at a high rate of speed. ALWAYS
wear safety glasses when using this
machine.
2. MOUNTING TO BENCH/STAND. An unse-
cured grinder may become dangerously
out of control during operation. Make sure
grinder is FIRMLY secured to a bench/
stand before use.
3. WHEEL SPEED RATING. Wheels oper-
ated at a faster speed than rated for
may break or fly apart. Before mount-
ing 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 grind-
ing 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 dam-
aged, it will usually fly apart shortly after
start-up. To protect yourself, always stand
to the side of the grinder when turning it
ON and allow it to gain full speed before
standing in front of it.
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Like all machinery there is potential danger
when operating this machine. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to lessen the pos-
sibility of operator injury. If normal safety
precautions are overlooked or ignored, seri-
ous personal injury may occur.
