Feed Speed Control
Your machine is equipped with a spiral, serrated
infeed roller and a solid 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 (A, Fig. 28) and sprockets (B, Fig. 28)
which take power directly from the cutterhead
through the oil bath gear box (C, Fig. 28).
The gear box has two feed speeds. These are
set by pulling out or pushing in the shift lever (D,
Fig. 28) while the machine is running. The feed
speed range is shown in Fig. 29.
Changing Accessories for Lowest
Feed Speed
The lowest feed speed for your planer (16.2 fpm
& 20.7 fpm) can be obtained by replacing the
lower (gear shaft) sprocket and the chain. See
Fig. 29. To change the sprocket and the chain
on your machine, proceed as follows:
1. Disconnect machine from power source.
2. Remove the three hex cap screws and
washers (E, Fig. 28).
3. Remove the three sprockets (B, Fig. 28)
from the infeed roller, outfeed roller and the
gear shaft at the same time.
4. When the sprockets (B, Fig. 28) are
removed, replace the lower sprocket which
will be assembled on the gear shaft.
5. Assemble the three sprockets and chains to
the shafts, and tighten the hex cap screws
(E, Fig. 28).
Return Rollers
The two return rollers on the top of 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.
