Chip Deflector

The chip deflector (B, Fig. 28) 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 29) 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 29) maintains proper tension at all times.

To gain access to the chain and sprockets:

1.Remove the handwheel from the machine.

2.Remove the socket head cap screw from the center of the cover, and remove the left triangular back plate. See Figure 30.

3.Pull the cover off the machine.

Always re-install cover over the chain and sprockets before operating planer.

The gear box has two feed speeds. These are set by pulling out or pushing in the shift lever (Figure 31). 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 32.

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

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.
