GearboxLubrication

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.

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.
