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 an oil/
grease soluble cleaner, such as shown on
page
22 of this manual.
if you thoroughly clean the components in this sec-
tion before lubricating them, the result will be silky
smooth movement when turning the handwheels,
which will result in much higher enjoyment on your
part and a longer lasting machine!
The following are the main components that
need to be lubricated:
•
trunnion slides and tilt leadscrew
•
Bevel gears, Elevation leadscrew, and
rails
Trunnion Slides & Tilt Leadscrew
Check every month. they are simply the grooved
portions of the trunnions where the cast iron com-
ponents slide against each other as the blade is
tilted (see
Figure 106).
Bevel Gears, Elevation Leadscrew
and Rails
Check every month. the bevel gears are shown
below in
Figure 107. When the blade height
handwheel is rotated, the bevel gears turn the ele-
vation leadscrew to raise/lower the motor housing
assembly, using the elevation rails as rigid guides.
in consideration of these mechanics, it is best to
start the lubrication process with the blade com-
pletely lowered.
Clean the trunnion slides out with mineral spir-
its and apply a dab of lithium grease into each
groove, and around the leadscrew next to where
it goes into the housing. Move the blade tilt back
and forth to spread the grease.

Clean all the components in
Figure 107 with min-
eral spirits before lubricating.
lubricate the bevel gears and elevation leadscrew
with lithium grease. apply a dab into the bevel
gear teeth and around the elevation leadscrew
right next to where it goes into the housing.
Brush a small amount of grease (or oil) onto the
elevation rails and wipe them down with a rag.
the goal is to spread a thin film over the rails to
mostly protect them from rust.
