Warning

1. Read and understand t he entir e owners manual bef ore attempti ng operation. Fail ure to comply with instructions and warnings may cause serious injury.

2. This lever hoist is designed and intended for use by properly trained and ex per ienced personnel only . If you are not familiar with the proper and safe operation of a lever hoist, do not use until proper training and knowledge have been obtained.

3. Do not use this lever hoist for other than its intended use. If used for other purposes, WMH Tool Group discl aims any real or implied warranty and holds itself harm less from any injury that may result from that use.

4. Do not use lever hoist to lift, support or transport people; or to lift or support loads over people.

5. Do not exceed the rated capacity of the hoist.

6. Do not use a “cheater pi pe” to extend the length of the handle.

7. Do not strike the handle with a hammer or any other object.

8. Do not use the chain as a sling. This may cause damage to the chain.

9. Always inspect t he lever hoist for damage prior to use. If hoi st is damaged, do not use until i t has been repaired or replaced.

10. Do not use m ore than one lever hoi st to lift or move a load. If this is unavoi dable, each hoist must have the same capacity as the load to be moved.

11. Never allow chain to “set” ov er sharp edges. All pull s or lifts must be made with strai ght chain that is free of obstacles.

12. If the lev er is difficult to operate, then the l oad exceeds the capacit y of the hoist. Select a hoist of larger capacit y.

13. Do not use a hoist if the chain is twisted, kinked or damaged.

14. Do not operate hoist unless load is centered between top and bottom hook s.

15. Always take time to study the job to be performed and choose the safest method. Do not place yourself or ot her people in an unsafe position.

16. Leave all internal mai ntenance and inspections to a qualif ied WMH Tool Group repair stati on.

17. Replace chain wit h factor y r eplac em ent chain only. Do not use any other type of chain.

18. Never use the hoi st if either hook i s stretched, def ormed, or has a broken or mi ssing safety l atch. Always replace the safety latch and/or the hook before placing the hoist back in servic e.

19. Be sure supporting structures and load-attaching devices used in conjunction with this lever hoist provide an adequate safety factor to handle the rated load plus the weight of the equipment. If in doubt, consult a qual ified structural engi neer .

20. Under stand and follow all pr oc edur es a s set forth in American National Standards ti tled “Performance Standard for Manually Lever Operated Chain Hoists.” ANSI/ASME HST-3M. This standard is available through the American Societ y of Mechanical Engineers, 345 East 47

St., NY, NY 10017.

21. K eep v isitors a safe distanc e from the work area. Keep children away.

K L M N O P Q R

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 component s must be rat ed equal to, or greater than the capacity of the lever hoist.

2. W ith the l ev er in the up posi ti on, c heck f or a clicking sound when the ha ndle i s rotated in a clockwise direction. If this sound is not present, do not use the hoi st.

3. With the lever in the up position, check fr ee 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 shoul d be replaced by a WMH Tool Group authori z ed r epair 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 i n a clean, dr y l oc ation.

6. Periodi cally apply a light coat of 30W oil to the chain. This will create easier operation and prolong the lif e of t he c hain.

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.

T h e lo ad c hai n su ppli ed wit h

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 th an 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 i s im portant to c heck t op 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.

Figure 1

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°, repl ace the hook (see Figure 3).

Operation

1. Set the top hook securel y .

2. Center load on bottom hook correctly (Figure 4). Incorrect loading is dangerous to

he 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. Pl ace t he select or lever on the handl e i n the center neutral posi tion (Figure 6) so that t he chain free-wheels. Note: Chain will only free-wheel when there i s no load. Take up slack by pulli ng on loose or free end, or by turning handwheel.

Figure 3

Figure 4

4. Move sel ector lever to the up positi on (see Figure 6). Ratchet handle to raise or pull load. Do not overload t he lev er hoist.

5. To release or lower load, turn selector lever on handle to the down position ( see Figure

6) and ratchet the handle.

Figure 5

Figure 6

Precautions

• During pulling operations, the operator should stand near t he side of the top hook on the opposite side of the lever. If the hand should sli p off the l ever, the lever will spring back away f rom the operator (Figure

7).

• During lif ting operati ons, 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 l ev er (B, Fi gur e 8).

• Prev ent the chain from dragging over sharp edges or corners. This will cause links to weaken, bend, or break (Figure 9).

Figure 7

Figure 8

• W hen usi ng a wire rope sli ng, the lever hoist must be applied al ong a strai ght line paral lel to the surf ace on which it is resting (Figur e

10).

Figure 9

Figure 10

•

hen lifting loads, hook the load wit h sl ings.

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 t he safety latch before pulli ng or lifting the load. Do not put one end on the i nside of the l atc h and leav e the other end on the hook end out side the latch.

Allowable Limits for Load Chain and Hooks

Load Chain

Carefully inspect the entire load chain. As illustrated in Figure 12, measure five consecutiv e li nks with cali pers to f ind t he length, Compare the resul ts with t he table i n Figure 12. Check every three feet and especially where excessiv e wear is indicated. Any load c hain that shows noticeabl e deformation or heat influence must be replaced wit h a new one.

Never extend load chain by welding a second piece to the original.

Hooks (Top and Bottom)

Replace the hook when “A” i n Fi gure 13 is wider than Limit A in the table. Never heat treat the hook or attach anything to the hook by welding.
