SAFETY INFORMATION

1. Keep the load within the rated capacity marked on the hoist’s lever. An excess load may

lead to an accident. The lever hoist is overloaded when the handle effort indicated in the
standard specifications is exceeded (See Table 1).

2. Before operating, lift and lower the load about 4" and test the brake system. Ineffective

braking may lead to an accident.

3. Loads must be lifted as slowly as possible. Load swinging and abrupt shocks will impose

on the lever hoist excessive burdens that may more than double the weight of the load.

4. Extreme temperatures will affect the durability of the lever hoist. In subzero

temperatures loads must be lifted and lowered very slowly and carefully.

5. When hooking, the load must be applied squarely to the center of the hook and the

hook must not come loose during operation. NEVER USE THE HOOK DIRECTLY ON A
LOAD (See Figure 4). Use the attachments as shown in Figure 5.

Figures 6 through 9 show improper hooking methods, which may cause the hook to
elongate or bend. These hooking methods may also obstruct the load chain flow to the load
sheave and prevent the lever hoist from operating properly.

6. Never run the chain out too far. When the lever hoist is run out beyond the range of lift, a

dangerous excessive load will be imposed on the load chain, stop grip and gearing.

7. The selector lever must be set to the “UP” position when the lever hoist is under a load

during hoisting or pulling.

8. Lifting a load with two lever hoists is not recommended. If the job is unavoidable, keep the

load well within the total rated capacity of each lever hoist to avoid overloading one or
both of the hoists; lift with exceptional care while maintaining proper balance, angle and
lifting speed.

In applications similar to Figures 6 through 9, be sure
to use the correct slings and attachments to ensure
safe operation and long life of the lever hoist.
