An essential step for lubrication is cleaning the compo- nents before lubricating them.

This step is critical because dust and chips build up on lubricated components, which makes them hard to move. Simply adding more grease to built-up grime will not result in smooth moving components.

Clean the components in this section with an oil/grease solvent cleaner.

The following are the main components that need to be lubricated:

•Trunnion Slides and Orientation Gears

•Worm Gears, Trunnion and Bearing Housing Teeth

Clean the trunnion slides with mineral spirits and a rag, and brush a dab of lithium grease into each groove. Move the blade tilt back and forth to spread the grease (see =`^li\0').

Also use a wire brush and mineral spirits to clean any debris or grime off the orientation gears, then apply lithium grease to the gears with a brush.

Clean away any built up grime and debris with a wire brush and mineral spirits from the worm gears and the teeth (see =@^li\91) on the bearing housing and trunnion. Then use a brush or rag to apply a thin coat of white lithium grease to the gears and teeth.
