Lubrication
It is essential to clean components before lubri-
cating them because dust and chips build up on
lubricated components and make them hard to
move. Simply adding more grease to them will not
yield smooth moving components.
Clean the components in this section with min-
eral spirits or other oil/grease solvent cleaner and
shop rags.
If you thoroughly clean the components in this
section before lubricating them, the result will
be silky smooth movement when turning the
handwheels, which will result in much higher
enjoyment on your part!
The following are the main components that
need to be lubricated:
• Trunnion Slides and Orientation Gears
• Worm Gears, Trunnion, and Bearing Housing
Teeth
Trunnion Slides
Clean out the front and rear trunnion slides with
mineral spirits and a rag, then apply lithium
grease into each groove. Move the blade tilt back-
and-forth to spread the grease (see Figure 109).

Leadscrew
Clean away any built up grime and debris from the
worm gear, bull gear, and leadscrew (see Figures

its. Allow the components to dry, then apply a thin
coat of white lithium grease.
