Lubrication

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.

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.

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.
