LUBRICATION
To ensure continued satisfactory operation of the hoist, all points requiring lubrication must be serviced with the correct lubricant at the proper time intervals indicated for each assembly. Correct lubrication is one of the most important factors in maintaining efficient operation.
The lubrication intervals recommended in Table 6 are based on intermittent operation of the hoist eight hours each day, five days per week. If the hoist is operated almost continuously, or for more than eight hours each day, or under severe conditions, more frequent lubrication will be required.

|
| LUBRICATION Frequency by usage level | ||
Component | Severe | Heavy | Normal |
Load chain | Daily | Weekly | At usage |
Hook | Daily | Weekly | At usage |
Gear case | Yearly | Every 3 years | Unnecessary |
Lubricant types and change intervals are based on operation in an environment relatively free of dust, moisture and corrosive fumes. Use only those lubricants recommended. Other lubricants may affect performance of the hoist. Approval for the use of other lubricants must be obtained from your
Whenever a hoist is disassembled for overhaul or replacement of parts, lubricate as follows:
Brake and Gear Assemblies
The gear and brake assemblies share a common oil bath. On larger capacity hoists, the output shaft from the motor is offset and utilizes a pinion gear to drive the sun gear. These gears operate in the motor casing oil bath.

LCA030S and Larger Hoists Oil Fill Level Positions
Fill to the level of the plug on the side of the motor housing and on the gear end in the center of the brake end cover.
Replace the oil in the brake and gear housing in accordance with Table 6 recommendations. Refer to Table 8 for recommended oil type. If hoist use is at normal frequency, the oil in the reduction housing is suitable for one year's operation without changing.
However, when hoist use is at greater frequency, or under severe conditions, the oil may need to be changed more often. To ensure correct performance, highest efficiency and long life, it is essential that the lubricating oil be maintained at the correct level. The recommended grade of
oil must be used at all times since the use of unsuitable oil may result in excessive temperature rise, loss of efficiency and possible damage to the gears.
Liftchain hoists are shipped from the factory with oil in the brake and reduction gear assembly.

Hook Assemblies
Hoist top and bottom hooks are supported by thrust bearings. These bearings must be packed with Ingersoll- Rand No. 68 Grease or a standard No. 2
1.Lubricate the hook and latch pivot points. Hook and latch should swivel/pivot freely.
2.Use
3.Lubricate hook bearings by applying several shots of grease from a grease gun to the grease fittings provided on the hook blocks.
Air Line Lubricator
If an air line lubricator is used, it should be replenished daily with ISO VG 100 (30W) lubricant (minimum viscosity 135 Cst at 104° F (40° C)).

1.Lubricate each link of the load chain weekly. Apply new lubricant over existing layer.
2.In severe applications or corrosive environments, lubricate more frequently than normal.
3.Lubricate hook and hook latch pivot points with same lubricant used on the load chain.
4.If required, clean chain with acid free solvent to remove rust or abrasive dust buildup and lubricate the chain.
5.Use
