Unpacking Open carton and check for shipping damage. Report any damage immediately to your distributor and shipping agent. Do not discard any shipping material until the Lever Hoist is assembled and running properly. Read this entire instruction manual thoroughly for set-up, maintenance and safety instructions. Contents of the Carton 1 1 1 Lever Hoist Owner's Manual Warranty Card Installation Support for the hoist may be hook, clevis pin, trolley, or beam clamp.
The load chain supplied with your JET lever hoist is designed, manufactured, and tested for proper fit and durability. If chain should ever need replacing, for your own safety use factory replacement chain only. Use of other than factory replacement chain may cause serious injury and/or damage to the lever hoist. Never extend load chain by welding a second piece to the original. Inspecting Hooks It is important to check top and bottom hooks for proper opening and other signs of deformation or damage.
Operation The JLH Mini Lever Hoist may be used either in vertical position as a hoist; or in angled or horizontal position as a puller. Below is the general procedure for operating the hoist: 1. Set the top hook securely. 2. Correctly center the load on the bottom hook (Figure 4). Incorrect loading is dangerous to the operator, the lever hoist, and the load. Figure 4 • Never load the hook in front of the safety latch (A, Figure 5). • Never load the hook tip (B, Figure 5).
Precautions • During lifting operations, do not stand under the load. • Do not use any extension on the lever handle. Do not use your foot to apply pressure to the lever handle. • Prevent the chain from dragging over sharp edges or corners. This will cause links to weaken, bend, or break. • When connecting to a wire rope sling, the lever hoist must be applied along a straight line parallel to the surface on which it is resting. See Figure 6. • When lifting loads, hook the load with slings.
Maintenance The lever hoist should be stored in a clean, dry environment. Clean and oil the hoist before storage. Hoists that are installed out-of-doors should be covered or brought inside when not in use. Periodically apply a light coat of 30W oil to the load chain. Also lubricate the safety latches and the bearings in the hooks. Allowable Limits for Load Chain and Hooks Hoist Capacity 5 Links Normal (mm) 5 Links Limit 0.25 ton 0.5 ton 45 60 46.3 61.
