Introduction

This manual is provided by Walter Meier (Manufacturing) Inc., covering the safe operation and maintenance procedures for a JET Model L-100 Series Chain Hoist. This manual contains instructions on installation, 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 Walter Meier. Walter Meier can also be reached at our web site: www.waltermeier.com.

Warning

1. Read and understand the entire owners manual before attempting assembly or operation.

2. Read and understand the warnings posted on the tool and in this manual. Failure to comply with all of

these warnings may cause serious injury and/or damage to property.

3. Replace the warning labels if they become obscured or are missing.

4. Keep visitors a safe distance from the work area. Keep children away.

5. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are

careless acts that can result in serious injury.

6. This chain hoist is designed and intended for use by properly trained and experienced personnel only.

If you are not familiar with the proper and safe operation of a chain hoist, do not use until proper training and knowledge have been obtained.

7. Do not use this chain hoist for other than its intended use. If used for other purposes, Walter Meier

(Manufacturing) Inc., disclaims any real or implied warranty and holds itself harmless from any injury that may result from that use.

8. Do not use to lift people or loads over people.

9. Do not exceed the rated capacity of the chain hoist.

10. Do not use more than hand power to pull the hand chain.

11. Do not use the load chain as a sling; this may cause damage to the chain.

12. Always inspect the chain hoist for damage prior to use. If the chain hoist is damaged, do not use until

it has been repaired or replaced.

13. Do not use more than one chain hoist to lift or move a load. If this is unavoidable, each chain hoist

must have the same capacity as the load to be moved.

14. Never allow the load chain to “set” over sharp edges. All lifts must be made with straight chain that is

free of obstacles.

15. If the hand chain is difficult to operate, then the load exceeds the capacity of the chain hoist. Select a

chain hoist of larger capacity.

16. Do not use a chain hoist unless load is centered between top and bottom hooks.

17. Always take time to study the job to be performed and choose the safest method. Do not place

yourself or other people in an unsafe position.

18. Leave all internal maintenance to a qualified Walter Meier repair station.

19. Replace the chain with factory replacement chain only. Do not use any other type of chain.

20. Never use the chain hoist if either hook is stretched, deformed, or has a broken or missing safety

latch. Always replace the safety latch and/or the hook before placing the chain hoist back into service.

21. Understand and follow all procedures as set forth in American National Standards titled “Performance

Standard for Hand Chain Manually Operated Chain Hoists.” ANSI/ASME HST-2M. This standard is available through the American Society of Mechanical Engineers, 345 East 47

St., NY, NY 10017.

This means that if precautions are not heeded, it may result in minor injury and/or

possible tool damage.

This means that if precautions are not heeded, it may result in serious injury or possibly

even death.

Specifications

Using the Chain Hoist

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 chain hoist.

2. If the chain hoist has not been used for an

extended period of time, check for proper operation before putting into service.

3. The brake mechanism must be kept clean and

free from dirt, water, and oil. Never allow oil to penetrate the brake mechanism. Always keep your chain hoist clean and store in a clean, dry location.

4. Although oiling the chain is not mandatory, a

light coat of 30-weight oil applied periodically to the chain will create easier operation and prolong the life of the chain.

5. Check the chain for damage and elongation.

Replace damaged chain before using the chain hoist.

The load chain supplied with your JET chain 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 hoist.

6. The top and bottom hooks on your JET chain

hoist are designed to open to warn of an overload. Both top and bottom hooks for 0.5 to 5 ton hoists have two indicator points (A, Figure

1) cast into the hook for measurement. Refer to Table 2 (page 13) to determine if a hook needs to be replaced.

Hooks for 10- and 20-ton hoists do not have indicator points. Measurements are made at the jaw opening (B, Figure 1).

7. 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.

Never side load the top or bottom hook; this practice is dangerous and could lead to serious injury.

8. If the vertical angle at the neck of the bottom or

top hook reaches 10°, replace the hook (see Figure 2).

Figure 1

Figure 2

Hooking the Load

1. Secure the upper hook.

2. Place the bottom hook securely into the object

to be lifted.

3. Place ropes or chain in the center of the bottom

hook, making sure the safety latch is secure. Never load the hook in front of the safety latch. See Figure 3.

4. Avoid lifting one load with two hoists. If this is

unavoidable, apply equal weight to both hoists and use hoists with the proper lift capacity.

Capacity of each hoist must be equal to the total load to be lifted.

5. Check that the chain is not twisted at the

bottom hook. All welds should face the same direction (Figure 4).

6. For hoists with two or more falls of chain, make

sure the bottom hook is not turned over. This may cause the chain to twist.

Raising the Load

To raise the load, pull the right side of the hand chain (A, Figure 5) clockwise.

Figure 3

Figure 4

To lower the load, pull the left side of the hand chain (B, Figure 5) counterclockwise.

Important: Make sure the hoist has an adequate length of load chain to raise or lower the load in a safe manner. Do not attempt to lower the hoist beyond its limit.

Figure 5

Hand Chain – Cutting and Installing

To cut the hand chain in order to increase or shorten:

To change the length of the hand chain, the chain must be cut and links added to increase the overall length or links removed to decrease the length. This is done as follows:

1. Insert one link lengthwise into the vise (Figure

6). Be sure that the side opposite the weld lies completely below the surface of the vise jaw (about 1/3 of a link). This prevents nicking or cutting the lower part of the link.

2. Using a hack saw, cut through the upper part of

the link at the weld.

3. Loosen the link, reposition the link vertically at

the edge of the vise with the level of the cut above the vise jaw (Figure 7).

4. Tighten the vise jaw.

5. Using an adjustable wrench, twist the link

horizontally from front to back. (Figure 8) Open just far enough to insert (or remove) a second chain link.

Figure 6

Figure 7

Note: Chain length is now ready to lengthen or shorten.

6. Insert or remove the second end link at the

opening in the first end link.

7. Using an adjustable wrench, twist the link

horizontally until the link is in the original closed position. See Figure 9.

Do not push the link inward

from the curved ends. This will distort the link. Check that the link is closed and free of twist.

8. If installing entire new chain, insert the end of

the hand chain into the groove at the top of the hand chain wheel (see Figure 10). Rotate the hand chain wheel and pull the chain through.

9. Re-weld the link at the cut.

10. Grind off excess on the weld so that it is

smooth.

Load Chain and Bottom Hook

Load Chain Inspection (all models)

Over time, the load chain will wear or elongate. This can cause damage to the hoist, breakage, or non-engagement of the load sheave.

Do not operate the hoist with a

twisted, kinked or damaged load chain. Do not splice the load chain. Check the chain for excessive wear or stretch. Failure to comply may cause serious injury.

1. Test the hoist under load in both the lifting and

lowering directions, observing the operation of chain and sprockets. Chain should feed smoothly into and away from the sprockets.

2. If the chain binds, jumps, or is noisy, make sure

it is clean and properly lubricated. If the trouble persists, inspect the chain and mating parts for wear, distortion, or other damage.

3. Clean the chain before inspection. Examine for

gouges, nicks, weld splatter, corrosion, and distorted links. Slacken the chain and move adjacent links to one side, looking for wear at the contact points. If you see wear or suspect stretching, measure the chain as follows:

Attaching Load Chain to Load Chain Sprocket (all models)

Install the new load chain onto the load chain sprocket as follows , referring to Fig. 10:

1. Position the load chain sprocket by rotating the hand chain wheel so that the wide and narrow grooves show.

2. Insert the load chain into the sprocket grooves so that the chain will wind up and back over the sprocket. Welds must face away from the sprocket.

3. Rotate the hand chain wheel so that the load chain falls six to eight inches at the back of the sprocket.

• Select an unworn, unstretched length of

chain (i.e. at the slack end).

• Suspend the chain vertically under tension

and, using a caliper type gauge, measure the outside length of several links about 12 to 24 inches.

• Measure the same number of links in used

sections and calculate the percentage of the increase in length.

4. If the length of used chain exceeds 2-1/2 percent of the unused chain, replace the chain. (See “Load Limits” on page 13 for specific link measurements.)

Do not add to the load chain.

Replace the entire chain. Failure to comply may cause serious injury.

Load Chain Removal (all models)

Remove the old load chain as follows while referring to Figure 11:

1. Remove the cotter pin (A) and the chain anchor pin (C) on the chain anchor (D), allowing the end of the chain to fall free.

2. Pull the hand chain (Fig. 5) until the load chain is completely removed from the gear assembly.

Figure 10

Referring to Figure 11:

4. Insert one end of the chain link (B) into the chain anchor (D).

5. Insert the chain anchor pin (C) through the chain anchor (D) and chain link (B) and secure with the cotter pin (A).
