Additional Safety for Grinders
Serious injury or death can occur from impact injuries if grinding wheel breaks apart during
use. Rotating grinding wheels can easily remove skin, or entanglement/amputation injuries can
occur from being caught in moving parts or in-running pinch points. Flying sparks can ignite
explosive or flammable materials. To minimize risk of getting hurt or killed, anyone operating
machine MUST completely heed hazards and warnings below.
SAFE MOUNTING & WORK AREA. An unse-
cured grinder may become dangerously out of
control during operation. Before use, verify grinder
is FIRMLY secured in a location free of explosive
or flammable materials.
STARTING GRINDER. If a wheel is damaged,
it will usually fly apart shortly after start-up. To
protect yourself, always stand to side of grinder
when turning it
ON and allow it to run for at least
one minute before standing in front of it.
VISUAL INSPECTION. Verify that grinding wheels
are free of cracks, chips, or dents in wheel surface
before installing. Do not use wheel if it has any
of these problems or it could break apart during
operation.
RING TEST. Perform a "ring test" on grinding
wheels before installation to ensure they are safe
to use. A wheel that does NOT pass ring test may
break or fly apart during operation.
WHEEL SPEED RATING. Wheels operated at a
faster speed than rated for may break apart dur-
ing operation. Before mounting a new wheel, be
sure wheel RPM rating is equal or higher than
speed of grinder. Never use unmarked wheels.
VIBRATING WHEEL. Never use a wheel that
vibrates. Replace wheel or shaft bearings
immediately.
SPARK DEFLECTOR GAP. Keep gap between
end of spark deflector and grinding wheel
between
1
⁄
8
" and
1
⁄
4
". If the gap is larger, exces-
sive sparks and abrasives can be expelled toward
the operator.
SPINDLE NUT. Only tighten wheel spindle nut
enough to drive wheel and prevent slippage.
EYE SHIELDS. Place eye shields close to grind-
ing wheel and re-adjust as wheel wears down.
TOOL REST POSITION. If tool rest is too far
away from wheel, workpiece may be pulled down,
causing loss of control and pulling your hand into
grinding wheel. Keep tool rest within
1
⁄
8
" from
wheel when operating. Replace grinding wheel
when tool rest gap is wider than
1
⁄
8
" and no addi-
tional adjustment can be made.
HAND & WHEEL CONTACT. Keep a firm grip
on workpiece and position your hands a safe dis-
tance away when grinding. Anticipate when work-
piece will heat up, and cool it before it becomes
too hot to hold, or use an appropriate clamp.
Avoid wearing gloves as they may get caught
in grinding wheel and cause even more serious
entanglement injuries.
WHEEL FLANGES. Only use flanges included
with grinder when mounting wheels. Other flang-
es may not properly secure wheel and cause an
accident. Do not use warped or damaged flanges,
and always use paper discs (blotters) between
wheels and flanges to reduce risk of flanges
cracking wheel when tightened.
EYE, FACE, & LUNG PROTECTION. Grinding
ejects small particles at a high rate of speed.
These particles can cause blindness, skin injuries
or respiratory damage. ALWAYS wear approved
clothing, safety goggles, face shield, and a respi-
rator for type of grinding to be done.
SIDE & TOP GRINDING. Grinding on side of
wheels can cause them to crack and burst—
unless wheel is rated for side grinding. Grinding
on top of wheels greatly increases risk of work-
piece kickback. Always grind on downward part
of wheel.
