Additional Safety Instructions for Grinders
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 wear
-
ing gloves as they may get caught in the
grinding wheel and cause even more seri
-
ous 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.
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 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 mounting a new
wheel, be sure the wheel RPM rating is
equal to 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, allow it to gain full speed and wait for
at least 1 minute 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.
