Additional Safety for Jointers
KICKBACK. Occurs when workpiece is ejected
from machine at a high rate of speed. To reduce
the risk of kickback-related injuries, use quality
workpieces, safe feeding techniques, and proper
machine setup or maintenance.
GUARD REMOVAL. Operating jointer without
guard exposes operator to knives/inserts. Except
when rabbeting, never remove guards for regular
operations or while connected to power. Turn joint-
er
OFF and disconnect power before clearing any
shavings or sawdust from around cutterhead. After
rabbeting or maintenance is complete, immediate-
ly replace all guards and ensure they are properly
adjusted before resuming regular operations.
DULL/DAMAGED KNIVES/INSERTS. Dull
knives/inserts can 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
and get stuck, increasing risk of kickback. Setting
outfeed table too low may cause workpiece to
become tapered from front to back. Always keep
outfeed table even with knives/inserts at top dead
center (highest point during rotation).
INSPECTING STOCK. Impact injuries or fire may
result from using poor workpieces. Thoroughly
inspect and prepare workpiece before cutting.
Verify workpiece is free of nails, staples, loose
knots or other foreign material. Workpieces with
minor warping should be surface planed first with
cupped side facing infeed table.
GRAIN DIRECTION. Jointing against the grain or
end grain can increase the 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.
MAXIMUM CUTTING DEPTH. To reduce risk of
kickback, never cut deeper than
1
⁄
8
" per pass.
CUTTING LIMITATIONS. Cutting a workpiece that
does not meet the minimum dimension require-
ments can result in breakup, kickback, or acciden-
tal contact with cutterhead during operation. Never
perform jointing, planing, or rabbeting cuts on
pieces smaller than 8" long,
3
⁄
4
" wide, or
1
⁄
4
" thick.
PUSH BLOCKS. Not using push blocks when sur-
face planing may result in accidental cutterhead
contact. 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. Loss of workpiece con-
trol while feeding can increase risk of kickback or
accidental contact with cutterhead. Support work-
piece continuously during operation. Position and
guide workpiece with fence. Support long or wide
stock with auxiliary stands.
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 back work toward infeed table.
SECURE KNIVES/INSERTS. Loose knives or
improperly set inserts can become dangerous pro-
jectiles or cause machine damage. Always verify
knives/inserts are secure and properly adjusted
before operation. Straight knives should never
project more than
1
⁄
8
" (0.125") from cutterhead
body.
Serious cuts, amputation, entanglement, or death can occur from contact with rotating cutterhead
or other moving components! Flying chips can cause blindness or eye injuries. Workpieces or
inserts/knives thrown by cutterhead can strike nearby operator or bystanders with deadly force.
To reduce the risk of these hazards, operator and bystanders MUST completely heed the hazards
and warnings below.
