ADjUSTMENTS
3. When the chip breaker contacts the gauge block, tighten
both lock nuts (A, Figure 27).
Chip Deflector
The chip The chip deflector (C, Figure 27) keeps wood chips
from falling into the outfeed roller. The deflector should be set
approximately 1/16" to 1/8" from the tip of the knives. Make
sure the deflector is oriented so the bevel on its front edge
matches the shape of the cutterhead.
Feed Speed Control
Your machine is equipped with a spiral, serrated infeed roller
and a solid steel outfeed roller. When the feed rollers are
engaged, they turn to feed the stock. The feed rollers slow
automatically when the machine is under heavy load for best
planing in all conditions. The feed rollers are driven by chains
and sprockets (see Figure 28) which take power directly from
the cutterhead through the oil bath gear box. The drive chain
does not need tensioning, as a tension device (Figure 28)
maintains proper tension at all times.
Tensioner
To gain access to the chain and sprockets (for example, when
performing maintenance) proceed as follows:
1. You may find it easier to remove the sprocket guard by first
removing the handwheel from the machine, though this is
not mandatory.
2. Remove the socket head cap screw from the center of the
cover using a 6mm hex wrench. Remove the left triangular
back plate (2 screws) using a 10mm wrench. See
Figure 29.
3. Pull the sprocket guard off the machine.
NOTE: Always re-install cover before operating planer.
The gear box has two feed speeds. These are set by pulling
out or pushing in the shift lever (Figure 30). Always change
feed speed while the machine is running. A label showing
the lever positions is affixed just above the lever. It is also
shown in Figure 30.

Stock Return Rollers
The two rollers on top the machine serve as a convenient rest
for stock. They save time and motion for the operator as
the stock is returned to the infeed side.

Do not attempt to change feed speed while
stock is passing through the machine.
Damage to the gearbox may result.
