Lubrication
It is essential to clean components before lubricating
them because dust and chips build up on these
components and make them hard to move. Simply adding
more grease to them will not yield smooth moving
components.
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!
Use mineral spirits, shop rags, and a stiff brush when
cleaning these components, then let them thoroughly dry
before applying the lubrication.
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 83).
Worm Gear, Bull Gear & Leadscrew
Clean away any built up grime and debris from the
worm gear, bull gear, and leadscrew (see Figures 84–85)
with a wire brush, rags, and mineral spirits. Allow the
components to dry, then apply a thin coat of white
lithium grease to them.
