Lubrication
The bearings on the cutterhead
are
factory lubricated and
sealed. They require
no lubrication.
Lubricate the two table elevation screws (A,
Figure 24) as needed. Raise the table and
remove the two screws holding the top of
the accordion cover (B, Figure 24) in place.
Pull the cover down and lightly grease the
elevating screws, see Figure 24.
Use an oiled cloth to wipe the ways (C,
Figure 24) weekly.
The gear box oil should be changed at least
once a year. Remove the drain plug (D,
Figure 25) to drain the oil into an appropriate
container. Replace the drain plug and fill the
gear box with 60 to 90 weight gear oil
through the fill hole (E, Figure 25). Capacity
is 0.494 gallon (1.87L). The sight glass (F,
Figure 25) should be checked periodically
and oil topped off as necessary.
The recommended lubrication for roller
chains used in medium to slow speed
operation is to simply wipe the chain clean.
When there is an appreciable buildup of dust,
dirt or wood shavings, use an oil cloth but
never pour the oil directly on the chain. Over-
oiling defeats the purpose of the lubrication,
since it tends to invite the collection of dust,
shavings, etc. and works into members of the
chain. This hastens wear and leads to
premature replacement.
Weekly oil the bearings on the infeed and
outfeed rollers, through the oil cups located
on the bearing blocks (Figure 26).
Recommended oil type is SAE 30.
