Model SB1494 SAFETY
Additional Safety for Grinders
Spark Deflector Gap. Keep gap between end of
spark deflector and grinding wheel between
1⁄8"and 1⁄4". If gap is larger, pinch hazard
increases and excessive sparks/abrasives can
be expelled toward operator.
Wheel Attachment. Only use flanges included
with grinder when mounting wheels. Other
flanges 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. Only tighten wheel spindle nut
enough to drive wheel and prevent slippage.
Eye Shields. Place eye shields close to grinding
wheel and re-adjust as wheel wears down.
Tool Rest Position. If tool rest is too far away
from wheel, it forms an “in-running nip
point"gap which may cause workpiece to be
pulled down, leading to loss of control and
pulling your hand into grinding wheel. Keep
tool rest within 1⁄8"of wheel when operating
to minimize risk of pinching and crushing
injuries. Replace grinding wheel when tool
rest gap is wider than 1⁄8", and when no
additional adjustment can be made.
Handle & Wheel Contact. Keep a firm grip on
workpiece and position your hands a safe
distance away when grinding. Anticipate
when workpiece will heat up, and cool it
before it becomes too hot to hold, or use
appropriate clamp. Avoid wearing gloves as
they may get caught in grinding wheel and
cause more serious entanglement injuries.
Safe Mounting & Work Area. An unsecured
grinder may become dangerously out of
control during operation. Before use, verify
grinder is FIRMLY secured in location
free of explosive or flammable materials.
Frequently clean grinding dust from beneath
grinder and inside wheel cover.
Starting Grinder. If 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. Never grind with wheel that
vibrates.
Wheel Inspection. Verify 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. Replace wheel or shaft
bearings immediately. 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 during
operation. Before mounting new wheel, be
sure wheel RPM rating is equal to or higher
than speed of grinder. Never use unmarked
wheels or wheel rated for lower speed than
grinder.
Avoiding Entanglement. Becoming entangled
in moving parts can cause severe injury or
death. Keep all guards and covers in place;
DO NOT wear loose clothing, gloves, or
jewelry; and tie back long hair.
Eye, Face, & Lung Protection. Grinding ejects
small particles at high rate of speed. These
particles can cause blindness, skin injuries,
or respiratory damage. ALWAYS wear
approved clothing, safety goggles, face
shield, and respirator for type of grinding.
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 workpiece kickback. Always grind on
downward part of wheel.
Serious injury or death can occur from impact injuries if grinding wheel breaks apart during use.
Entanglement/amputation injuries can occur from being caught in moving parts or in-running
pinch points. Flying sparks can ignite explosive or flammable materials. Rotating grinding wheels
can easily remove skin. To minimize risk of getting hurt or killed, anyone operating machine MUST
completely heed hazards and warnings below.
