Additional Safety For Jointers - Grizzly G0834 Owner's Manual

Additional Safety for Jointers

Serious cuts, amputation, entanglement, or death can occur from contact with rotating cutterhead
or other moving components! Flying chips from cutting operations can cause blindness or eye
injuries. Workpieces or inserts/knives thrown by cutterhead (kickback) can strike nearby operator
or bystanders with deadly force. To reduce the risk of serious personal injury from these hazards,
operator and bystanders MUST completely heed the hazards and warnings below.
KICKBACK. Occurs when workpiece is ejected
from machine at a high rate of speed. Kickback
injuries occur from getting struck by workpiece or
hands being pulled into cutterhead. To reduce the
risk of kickback, only use proper workpieces, safe
feeding techniques, and proper machine setup or
maintenance.
GUARD REMOVAL. Operating jointer without
guards unnecessarily exposes operator to knives/
inserts and other hazardous moving parts. Except
when rabbeting, never operate jointer or allow it to
be connected to power if any guards are removed.
Turn jointer OFF and disconnect power before
clearing any shavings or sawdust from around cut-
terhead. After rabbeting or maintenance is com-
plete, immediately replace all guards and ensure
they are properly installed/adjusted before resum-
ing regular operations.
DULL OR DAMAGED KNIVES/INSERTS. Dull or
damaged knives/inserts increase risk of kickback
and cause poor workpiece finish. Only use sharp,
undamaged knives/inserts.
OUTFEED TABLE ALIGNMENT. Setting outfeed
table too high can cause workpiece to hit table or
get stuck while feeding. Setting outfeed table too
low may cause workpiece to rock or shift while
feeding. Both of these results will increase risk
of kickback. Always keep outfeed table even with
knives/inserts at highest point during rotation.
INSPECTING STOCK. Impact injuries or kick-
back may result from using improper workpieces.
Thoroughly inspect and prepare workpiece before
cutting. Verify workpiece is free of nails, staples,
loose knots or other foreign material. Warped
workpieces must be surface planed first with
cupped side facing down.
MAXIMUM CUTTING DEPTH. To reduce risk of
kickback, never cut deeper than
-10-
GRAIN DIRECTION. Jointing against the grain
or end grain can increase risk of kickback. It also
requires more cutting force, which produces chat-
ter or excessive chip out. Always joint or surface
plane WITH the grain.
CUTTING LIMITATIONS. Cutting workpieces that
do not meet minimum dimension requirements can
result in kickback or accidental contact with cutter-
head. Never perform jointing, planing, or rabbeting
cuts on pieces smaller than 14" long,
⁄ " thick.

PUSH BLOCKS. Push blocks reduce risk of acci-
dental cutterhead contact with hands. Always use
push blocks when planing materials less than 3"
high or wide. Never pass your hands directly over
cutterhead without a push block.
WORKPIECE SUPPORT. Poor workpiece sup-
port or loss of workpiece control while feeding will
increase risk of kickback or accidental contact
with cutterhead. Support workpiece with fence
continuously during operation. Support long stock
with auxiliary tables if necessary.
FEED WORKPIECE PROPERLY. Kickback or
accidental cutterhead contact may result if work-
piece is fed into cutterhead the wrong way. Allow
cutterhead to reach full speed before feeding.
Never start jointer with workpiece touching cutter-
head. Always feed workpiece from infeed side to
outfeed side without stopping until cut is complete.
Never move workpiece backwards while feeding.
SECURE KNIVES/INSERTS. Loose knives or
improperly set inserts can be thrown from cutter-
head with dangerous force. Always verify knives/
inserts are secure and properly adjusted before
operation. Straight knives should never project
more than
⁄ " per pass.
