table height chain & Sprockets
the table leadscrews are synchronized by the
table height chain and sprockets located under-
neath the base of the planer. remove the front
and rear cabinet panels to access these parts
(see
figure 30). use shop rags and mineral spir-
its to clean away debris and grime, then brush on
a light coat of multi-purpose grease to the chain
and sprockets.

Drive chain & Sprockets
the infeed and outfeed rollers receive the trans-
ferred power from the cutterhead through the drive
chain system on the right side of the machine, as
shown in
figure 31.
remove the table height handwheel and the
safety covers attached to the inside of the drive
chain cover, then remove the cover to access
these parts.
use shop rags and mineral spirits to clean away
any debris and grime, then brush on a light coat of
multi-purpose grease to the chain and sprockets.

Gearbox Oil
the gearbox oil should be changed after the first
20 hours of operation to clear away any debris
inside the gearbox, then changed annually there-
after.
Although it is not necessary to remove the drive
chain cover to access the fill and drain plugs, it is
more convenient to do so (see
figures 32–33).
replace the gearbox oil with 80W–90W gear oil
until it just reaches the fill plug.
