G1021X 15" Extreme Series Planer
-23-
The Model G1021X features factory-sealed bear-
ings. Should a bearing fail, your planer will prob
-
ably develop a noticeable rumble/vibration, which
will increase when the machine is put under load.
Bearings are standard sizes and can be replaced
through Grizzly.
Proper lubrication of other planer components are
essential for long life and trouble-free operation.
Below is a list of components that require periodic
lubrication. Schedules are based on daily use.
Adjust accordingly for your level of use.
Lubrication
Figure 21. Gearbox oil drain/fill locations
(sprockets and chains removed for clarity).
Drive Chain: The drive chain should be inspected
and lubricated monthly. Check sprockets, chains
and cotter pins during inspection. Some chains
will have master links instead of cotter pins.
Feed Rollers
: Daily lubrication of feed rollers is
crucial to the operation of your planer. Lubricate
before start-up. Each end of each power feed roll
-
er has an oiling port located on the top of the head
casting (Figure 22). Apply a SAE 30W oil, making
sure that the lubricant penetrates the bearing.

Fill
Drain
Always disconnect power
to the machine before
lubricating! Failure to do
this may result in serious
personal injury.
Columns/Lead Screws: The four columns should
be lubricated weekly with SAE 30W oil. Unfasten
dust covers to gain access. The four lead screws
should be lubricated with general purpose grease
once a month.
Worm Gear: The worm gear should be inspected
monthly and lubricated with general purpose
grease when needed. Remove the worm gear box
to inspect. See parts diagram for location.
Chain: The table height adjustment chain should
be inspected monthly and lubricated with general
purpose grease when needed.
Gear Box
: Gear box oil should be changed after
the first 20 hours of operation (see Figure 21). It
is not necessary to remove the chain drive cover
to access the fill/drain plugs, but doing so will give
you easier access.
Replace with 80W-90W gear oil. Inspect levels
periodically and change yearly. Replace gear oil
more frequently under heavy use. Fill until oil
reaches the top of the filler plug port for correct
oil level.
