-34- G1021Z 15" Planer
Lubrication
The Model G1021Z features factory-sealed bear-
ings. A sealed bearing requires no lubrication
during its lifetime. Should a bearing fail, your
planer will probably develop a noticeable rumble,
which will increase when the machine is put
under load. If allowed to get worse, overheating of
the journal containing the bad bearing could
occur. If the bad bearing is not replaced, it will
eventually seize - possibly doing damage to other
parts of the machine. Bearings are standard sizes
and can be replaced through Grizzly.
Proper lubrication of other components of the
Model G1021Z are essential for long life and trou-
ble-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.
Columns/Lead Screws - The four columns
should be lubricated weekly with light oil.
Unfasten dust covers to gain access. The four
lead screws should be lubricated with general
purpose grease once a month.
Worm Gear - The worn gear should be inspected
monthly and lubricated 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 when need-
ed. A good quality bicycle chain lubricant works
well for periodic lubrication.
Gear Box - Gear box oil should be drained after
the first 20 hours of operation. See Figure 40.
Replace with 80W-90 gear oil. Inspect levels peri-
odically 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.
Drive Chain - The drive chain should be inspect-
ed and lubricated monthly. Check sprocket, chain
and cotter pin during inspection. Use a general
purpose grease. Some chains will have master
links instead of cotter pins.
Feed Rollers - The infeed/outfeed pressure
setscrews double as lubrication ports for the
rollers. See Figure 41. Add 1-2 drops of light
machine oil to all ports before each use. Daily
lubrication of feed rollers is crucial to the opera-
tion of your planer. Lubricate before start-up.
Apply a light oil, making sure that the lubricant
penetrates the bearing.
