H2801 4" Jointer -17-
Figure 14. Push blocks.
Always use push blocks (Figure 14) when joint-
ing wood that is narrower than 3" or when jointing
a workpiece that cannot be held firmly while feed-
ing, or does not adequately protect your hands
from the moving cutterhead. To use the push
blocks:
1. Grasp the push blocks firmly, with one in
each hand.
2. Place the push blocks flat on top of the work-
piece, holding the workpiece with firm pres-
sure on the table and against the fence.
3. Use the hand-over-hand motion described in
the “Feeding Workpiece” instructions to
maintain control over the workpiece at all
times.
When jointing a workpiece that is narrower than
the push blocks, tilt the push blocks so they clear
the cutterhead guard while feeding.
Push Blocks
To feed the workpiece:
1. Hold the board firmly down on the infeed
table and against the fence. Use push blocks
if you are surface planing or your situation
requires it.
2. Feed the board toward/over the cutterhead
at a consistent and even rate of speed. Do
not force the board into the cut. Also, any
hesitation or stopping could cause uneven
cuts or cutting inconsistencies on your work-
piece.
3. Use a hand-over-hand action to “walk” the
workpiece over the cutterhead. Repeat this
hand-over-hand action until the entire length
of the board is cut.
4. Follow through with the cut until the work-
piece clears the cutterhead and the cutter
guard springs back into its original position
over the cutterhead.
If the nature of the workpiece forces you to feed
against the grain, make very light cuts and feed
slowly.
When cutting long workpieces, extra support is
needed to avoid injury or a kickback. Use an
extension table on the outfeed side or get help
from another person to support the workpiece.
