G0550/G0551 15" Planer -25-
The gearbox is located just behind the handwheel
on the right side of the planer. The gearbox trans-
fers power from the belt-driven cutterhead to the
power feed rollers. The two-speed transmission
is controlled by a push/pull lever on the right side
of the planer. When engaged, the power feed
rollers will move lumber through the planer at
either 16 or 20 feet-per-minute. The center lever
position is neutral.
To inspect the gearbox:
1. Loosen the socket head cap screw on the
gearbox cover, and gently pull the cover off
the roll pins that hold it in place.
2. Check the bolts that hold the sprockets in
place. Inspect the drive chains to ensure that
the retaining clips are in place. Replace the
clips if necessary. See Figure 21.
Figure 21. Gearbox.
Since all bearings are sealed and permanently
lubricated, simply leave them alone until they
need to be replaced. DO NOT lubricate them.
The following is a list of features and parts
that need lubrication:
Columns/Lead Screws—The four columns
should be lubricated with light machine oil once a
week. The four lead screws should be lubricated
with general purpose grease once a month. See
Figure 22.
