Additional Safety For Shapers - Grizzly G0900 Owner's Manual

Additional Safety for Shapers

Serious cuts, amputation, entanglement, or death can occur from contact with rotating cutter.
Cutters or other parts improperly secured to spindle can fly off and strike nearby operators with
great force. Flying debris can cause eye injuries or blindness. To minimize risk of getting hurt
or killed, anyone operating shaper MUST completely heed hazards and warnings below.
AVOIDING CUTTER CONTACT: Keep unused
portion of cutter below table. Use smallest table
insert possible. Adjust fences and guards as close
as practical to cutter, or use a zero-clearance
fence or box guard. Always keep some type of
guard or other protective device between your
hands and cutter at all times!
PROTECT HANDS/FINGERS: While feeding
workpiece, avoid awkward hand positions. Never
pass hands directly over, or in front of, cutter. As
one hand approaches a 6-inch radius point from
cutter, move it in an arc motion away from cutter,
and reposition it on the outfeed side.
FEEDING WORKPIECE: To reduce risk of acci-
dental cutterhead contact, always use push
blocks or some type of fixture, jig, or hold-down
device to safely feed workpiece while cutting.
Use an outfeed support table if shaping long
workpieces to ensure proper support throughout
entire cutting procedure. ALWAYS feed workpiece
AGAINST rotation of cutter. NEVER start shaper
with workpiece contacting cutter!
CUTTING DEPTH: Never attempt to remove too
much material in one pass. Doing this increases
risk of workpiece kickback. Instead, make sev-
eral light passes—this is a safer way to cut and it
leaves a cleaner finish.
WORKPIECE CONDITION: Shaping a workpiece
with knots, holes, or foreign objects increases
risk of kickback and cutter damage/breakage.
Thoroughly inspect and prepare workpiece before
shaping. Always "square up" a workpiece before
shaping or flatten workpiece edges with a jointer
or planer. Rough, warped, or wet workpieces
increase risk of kickback.
CUTTER POSITIONING: Whenever possible,
make shaping cuts with cutter on underside of
workpiece to reduce operator exposure to cutter.
-10-
SMALL WORKPIECES: There is a high risk of
accidental cutter contact with small workpieces,
because they are closer to cutter and more diffi-
cult to control. To reduce your risk, only feed small
workpieces using jigs or holding fixtures that allow
your hands to stay safely away from cutter. When
possible, shape longer stock and cut to size.
SAFE CUTTER CLEARANCES: Operator or
bystanders may be hit by flying debris if cut-
ter contacts fence, guard, or table insert upon
startup. Always ensure any new cutter setup has
proper cutter rotational clearance before startup.
SAFE CUTTER INSTALLATION: Improperly
secured knives/inserts, cutters, or rub collars may
become dangerous projectiles if they come loose.
Always ensure keyed washer is directly under cap
screw and that cap screw is very secure. If spindle
does not use a keyed washer, always tighten two
spindle nuts together, and ensure BOTH are very
secure. Never use cutters/bits rated for an RPM
lower than spindle speed.
AVOIDING CLIMB CUTS: Feeding workpiece in
same direction of cutter rotation is a "climb cut."
Climb cutting can aggressively pull workpiece—
and hands—into cutter. Always first verify direc-
tion of cutter rotation before starting, and always
feed workpiece AGAINST cutter rotation.
SAFETY GUARDS. To reduce risk of unintention-
al contact with cutter, always ensure included cut-
ter guard, or a properly dimensioned box guard, or
some other type of guard is installed and correctly
positioned before operation.
CONTOUR SHAPING: To reduce risk of unin-
tentional cutter contact while freehand shaping
or using a rub collar as a guide, always use an
overhead or "ring" type guard. To reduce kickback
risk, always use starting pin or pivot board when
starting the cut. NEVER start shaping at a corner!
