OPERATION
15
WARNING:
Any article that encounters jointer blades may be forcibly ejected from the joint-
er, creating risk of injury. Make sure the wood is free from foreign materials before attempting to
joint.
FEED A WORKPIECE
Feed rate refers to the rate at which wood is passed over the
blades. An even feed rate produces a uniform finish.
1. Hold the work piece firmly down on the feed table and against
the fence.
2. Feed the work piece at an even rate over the cutterhead. Any
hesitation or stopping will cause a “step” to be cut in the work
piece. See Figs. 21- 23 for different feeding methods.
3. As your trailing hand passes over the cutterhead, remove your
leading hand and place behind your trailing hand and repeat un-
til the entire length of the workpiece has been cut. Use a push
block (Fig. 23 - 1) and a push stick (Fig. 23 - 2) to hold and feed
the workpiece when jointing wood that is narrower than
3 inches or thinner than 3 inches
4. Cut with the grain whenever possible (Fig. 25). Do not feed
against the end grain (Fig. 24), otherwise the workpiece may
split and shatter. If the nature of the workpiece requires you to
joint against the grain, take extremely light cuts and feed slowly.
When using long work pieces, use extra supports at both ends
of the jointer.
AVOID DAMAGE TO BLADES
Jointers are a precision woodworking machine and should be used on quality lumber only. Do not join
dirty boards; dirt and small stones are abrasive and will wear out the blades.
For proper operation, it is preferable to use the jointer with a dust collecting system attached to the
exhaust port in the rear of the jointer. Attaching a dust collecting system is highly recommended when
taking deeper cuts to prevent clogging of wood chips.
Remove nails and staples. Only use the jointer to cut wood. Avoid knots. Heavily cross-grained wood
makes knots hard. Knots can come loose and jam blades.
Assess the value of badly warped boards. You may be tempted to take a deep cut to square the boards
quickly, when a better approach is to use several passes with a shallower cut.
