Do not use your foot to applypressure to the lever handle.• Prevent the chain from dragging over sharpedges or corners. This will cause links toweaken, bend, or break.• When connecting to a wire rope sling, thelever hoist must be applied along a straightline parallel to the surface on which it isresting. See Figure 7.• When lifting loads, hook the load with slings.Do not use the lever hoist chain as asling (Figure 8).• Both ends of a sling or rope must becompletely on the inside of the safety latchbefore pulling or lifting the load. Do not putone end on the inside of the latch and leavethe other end on the hook end outside thelatch.Point HooksPoint or “shipyard” hooks are available for yourJET lever hoist, in 1.6 ton and 3.2 ton loadsizes. They are available in both upper andlower hook styles.Point hooks are used in the metal and shipbuilding industries, and are designed forpositioning steel plate and fixtures beforewelding.Overload ProtectionSome models of the JLH Lever Hoist haveoverload protection in the form of a slip clutch(these are identified by “WO” in the modelnumber). The slip clutch is effective between1.25 to 1.55 times the rated hoist capacity.The slip clutch will allow the lever handle torotate without lifting the load, if the load is tooheavy for the hoist. The slip clutch has beenpre-adjusted at the factory and should notrequire any adjustment by the user. If futureadjustment or repair to the slip clutch shouldever be needed, this must be done by qualifiedpersonnel.Figure 7Figure 8
