G0633/G0634 Jointer/Planer Combo Machine
Additional Safety Instructions for Jointers
Like all machines there is danger associated
with this machine. Accidents are frequently
caused by lack of familiarity or failure to pay
attention. Use this machine with respect
and caution to lessen the possibility of
operator injury. If normal safety precautions
are overlooked or ignored, serious personal
injury may occur.
1. JOINTER KICKBACK. "Kickback" is when
the workpiece is thrown off the jointer table
by the force of the cutterhead. Always use
push blocks and safety glasses to reduce
the likelihood of injury from “kickback.” If
you do not understand what kickback is,
or how it occurs,
DO NOT operate this
machine.
2. CUTTERHEAD ALIGNMENT. Keep the top
edge of the outfeed table aligned with the
cutterhead knife or insert at top dead center
(TDC) to avoid kickback and personal inju-
ries.
3. PUSH BLOCKS. Always use push blocks
whenever surface planing. Never pass your
hands directly over the cutterhead without a
push block.
4. WORKPIECE SUPPORT. Supporting the
workpiece adequately at all times while
cutting is crucial for making safe cuts and
avoiding injury. Never attempt to make a cut
with an unstable workpiece.
5. KICKBACK ZONE. The "kickback zone"
is the path directly through the end of the
infeed table. Never stand or allow others to
stand in this area during operation.
6. MAXIMUM CUTTING DEPTH. The maxi-
mum cutting depth for one pass is 1 ⁄
8
".
Never attempt any single cut deeper than
this!
7. JOINTING WITH THE GRAIN. Jointing
against the grain or jointing end grain is
dangerous and could produce chatter or
excessive chip out. Always joint with the
grain.
8. KEEPING GUARDS IN PLACE. With the
exception of rabbeting, all operations must
be performed with the cutterhead guard in
place. After rabbeting, be sure to replace
the guard.
9. PROPER CUTTING. When cutting, always
keep the workpiece moving toward the
outfeed table until the workpiece has passed
completely over the cutterhead. Never back
the work toward the infeed table.
10. USING GOOD STOCK. Jointing safety
begins with your lumber. Inspect your
stock carefully before you feed it over the
cutterhead. Never joint a board that has
loose knots, nails, or staples. If you have
any doubts about the stability or structural
integrity of your stock, DO NOT joint it!
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
