Precautions
Before operating the lever hoist, please take note of the following precautions:

• Read and understand the entire owner’s manual before attempting operation.
• This lever hoist is designed for use by properly trained and experienced personnel only. Do not use until proper training and knowledge have been obtained.

Introduction

This manual is provided by WMH Tool Group covering the safe operation and maintenance procedures for the JET Model JPNX Series Lever Hoists (also called “Pullers”). This manual contains instructions on safety precautions, general operating procedures, maintenance instructions, and parts breakdown. This tool has been designed and constructed to provide years of trouble free operation if used in accordance with instructions set forth in this manual. If there are any questions or comments, please contact either your local supplier or WMH Tool Group. WMH Tool Group can also be reached at our web site: www.wmhtoolgroup.com.

Specifications

The above specifications were current at the time this manual was published, but because of our policy of continuous improvement, WMH Tool Group reserves the right to change specifications at any time and without prior notice, without incurring obligations.

Dimensions

Prior to Operation

1. Support for the hoist may be hook, clevis pin, trolley, or beam clamp. Whatever method of suspension is chosen, the support components must be rated equal to, or greater than the capacity of the lever hoist.

2. With the lever in the up position, check for a clicking sound when the handle is rotated in a clockwise direction. If this sound is not present, do not use the hoist.

3. With the lever in the up position, check free play in handle rotation. Free play is measured by the distance the handle travels before resistance or gearing is felt. If free play has reached 3/4 of a turn, the friction discs are worn and should be replaced by a WMH Tool Group authorized repair station.

4. If the lever hoist has not been used for an extended period of time, check for proper operation before putting into service.

5. The brake mechanism must be kept clean and free from dirt, water, and oil. Never allow oil to penetrate the braking mechanism. Always keep your lever hoist clean and store in a clean, dry location.

6. Periodically apply a light coat of 30W oil to the chain. This will create easier operation and prolong the life of the chain.

7. Check the chain for damage and elongation. Use the chain gauge on the bottom end of the chain as a guide. If the chain links do not fit inside the chain gauge, as shown in Figure 1, then the links have become elongated and the chain must be replaced.
   WARNING The load chain supplied with your JET lever hoist is designed, manufactured, and tested for proper fit and durability. Over a period of time, the chain may need to be replaced. 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.

8. The top and bottom hooks on your JET lever hoist are designed to open to warn of an overload. It is important to check top and bottom hooks for proper opening. If the safety latch no longer contacts the hook opening, replace the hook. Another way to check the opening is by using the chain gauge. Position the gauge as in Figure 2.

9. If the gauge does not contact both sides of the hook, replace the hook. Never side load the top or bottom hook; this practice is dangerous and could lead to serious injury.
10. If the vertical angle at the neck of the bottom or top hook reaches 10°, replace the hook (see Figure 3).

Operation

1. Set the top hook securely.
2. Center load on bottom hook correctly (Figure 4). Incorrect loading is dangerous to the operator, the lever hoist, and the load. Never load the hook in front of the safety latch (A, Figure 5). Never load the hook tip (B, Figure 5). Never load the hook off the centerline (C, Figure 5). Never load the hook sideways (D, Figure 5).

3. Place the selector lever on the handle in the center neutral position (Figure 6) so that the chain free-wheels. Note: Chain will only free-wheel when there is no load. Take up slack by pulling on loose or free end, or by turning handwheel.
4. Move selector lever to the up position (see Figure 6). Ratchet handle to raise or pull load. Do not overload the lever hoist.
5. To release or lower load, turn selector lever on handle to the down position (see Figure 6) and ratchet the handle.

Precautions

• During pulling operations, the operator should stand near the side of the top hook on the opposite side of the lever. If the hand should slip off the lever, the lever will spring back away from the operator (Figure 7).
• During lifting operations, do not stand under the load.
• Do not use an extension on the lever (A, Figure 8). Do not use a foot to apply pressure to the lever (B, Figure 8).

• Prevent the chain from dragging over sharp edges or corners. This will cause links to weaken, bend, or break (Figure 9).
• When using a wire rope sling, the lever hoist must be applied along a straight line parallel to the surface on which it is resting (Figure 10).

• When lifting loads, hook the load with slings. Do not use the lever hoist chain as a sling (Figure 11).
• Both ends of a sling or rope must be completely on the inside of the safety latch before pulling or lifting the load. Do not put one end on the inside of the latch and leave the other end on the hook end outside the latch.

Allowable Limits for Load

Chain and Hooks Load Chain

• Carefully inspect the entire load chain. As illustrated in Figure 12, measure five consecutive links with calipers to find the length, Compare the results with the table in Figure 12. Check every three feet and especially where excessive wear is indicated. Any load chain that shows noticeable deformation or heat influence must be replaced with a new one.
• Never extend load chain by welding a second piece to the original.

Hooks (Top and Bottom)
Replace the hook when “A” in Figure 13 is wider than Limit A in the table. Never heat treat the hook or attach anything to the hook by welding.
