An essential part of lubrication is cleaning the com-
ponents before lubricating them. This step is critical
because dust and chips build up on lubricated compo-
nents, which makes them hard to move. Simply adding
more grease to built-up grime will not result in smooth
moving parts. Motor bearings need no lubrication.

LUBRICATION!
Pillow.Block.Bearings
Lubricate every 20 hours of operation. Open the top
cover, and use a grease gun to pump one or two shots of
a high-quality white lithium grease into each grease fitting
(see
Figure.16
), located on the top of each pillow block
bearing.
These should be lubricated with lithium grease every six
months. Use mineral spirits and a stiff brush to clean the
lift screw (see Figure 17), then paint lithium grease onto
the threads. Move the table up or down to spread the
grease thoroughly over the threads.
Lift.Screws
Helical.Gears
Lubricate every six months. Remove the dust cover to
access the gears. Use mineral spirits and a stiff brush to
clean these gears (see Figure 18). Paint lithium grease
onto the threads.
Drive.Chain
Inspect and lubricate monthly. Remove the front chain
cover to access. Check the sprockets, the chain (see
Figure
17
), and the master links during inspection. Clean
the chain with mineral spirits and a brush or rag, then
apply light machine oil to the chain. Turn the hand crank
to move the conveyor up or down to distribute the oil. Do
not apply too much oil, as it will attract dirt and sawdust
that will clog the chain mechanism.
