HOIST SAFETY IS UP TO YOU...
–DO NOT APPLY MORE THAN RATED LOAD.
1 CHOOSE THE RIGHT HOIST FOR THE JOB...
Choose a Yale Lever Hoist with a capacity
or the job. Know the capacities of your
f hoists and the weight of your loads. Then
atch them.
m
2 INSPECT
All hoists should be visually inspected
efore use, in addition to regular, periodic
b maintenance inspections.
Inspect hoists for operational warning notices and legibility.
Deficiencies should be noted and brought to the attention of supervisors. Be sure defective hoists are tagged and taken out of service until repairs are made.
The application, the size and type of load,
he attachments to be used and the period
t of use must also be taken into consideration
n selecting the right hoist for the job.
i
– DO NOT OPERATE DAMAGED OR MALFUNCTIONING UNIT. – DO NOT OPERATE WITH TWISTED, KINKED OR DAMAGED
CHAIN.
nder no circumstances should you operate
U a malfunctioning hoist.
Check chain for gouged, twisted, distorted links and foreign material. Do not operate hoists with twisted, kinked or damaged chain links.
– DO NOT PULL AT AN ANGLE. BE SURE LEVER HOIST AND
LOAD ARE IN A STRAIGHT LINE.
– DO NOT USE UNLESS FRAME AND CHAIN FORM A
STRAIGHT LINE BETWEEN HOOKS. – DO NOT USE IF FRAME IS IN CONTACT WITH ANY OBJECT. – DO NOT USE LOAD CHAIN AS A SLING. – DO NOT USE AN EXTENSION ON THE LEVER.
Remember the hoist was designed to ease
ur burden and carelessness not only
o endangers the operator, but in many cases,
valuable load.
a
Load chain should be properly lubricated.
Hooks that are bent, worn or whose
penings are enlarged beyond normal
o throat opening should not be used. If latch does not engage throat opening of hook, hoist should be taken out service.
Chains should be checked for deposits of foreign material which may be carried into the hoist mechanism.
Check brake for evidence of slippage under load.
3 USE HOIST PROPERLY
Be sure the hoist is solidly held in the uppermost part of the support hook arc.
Be sure the hoist and load are in a straight line. Do not use unless frame and chain form a straight line between hooks.
4 PRACTICE CAUTION ALWAYS
Do not lift co-workers with a Yale Lever Hoist.
Make sure everyone is clear of the load when you apply tension.
Do not remove or obscure operational warning notices.
VIOLATION OF ANY OF THESE WARNINGS LISTED MAY RESULT SERIOUS PERSONAL INJURY TO THE
iii
OPERATOR OR NEARBY PERSONNEL BY RELEASED LOAD OR BROKEN HOIST COMPONENTS.
Be sure load is hooked securely. Do not tip load the hook. Do not load hook latch. Hook latch is to prevent detachment of load under slack chain conditions only.
– DO NOT LIFT PEOPLE OR LOADS OVER PEOPLE.
Do not operate with hoist frame resting against any object. Apply the load gently. Do not jerk it.
5 OPERATOR SERVICE
CLEANING: Lever Hoists should be kept clean and free of dust, dirt, moisture, etc., which will in any way affect the operation or safety of the equipment. LUBRICATION: Chain should be properly lubricated. AFTER REPAIRS: Carefully operate the hoist before returning it to full service.
Never use an extension on the lever! You’re dangerously overloading the hoist if you exceed the rated lever pull or if you have to use a lever extension to lift or pull a load.

load chain for long and dependable service.
Latchlok®Hooks
Latchlok hooks are available to replace the standard latch type hooks. The unique design of the Latchlok hook assures that it will stay locked until the operator releases it by depressing the release button. It will not open accidentally­even if the load chain goes slack. Once opened, it can be shut with one hand or by the weight of the load when it is lifted. Latchlok hooks can be supplied with the hoist or it can be provided in kit form for lever hoists already in service.
We reserve the right to change materials or design if, in our opinion, such changes will improve our product. Abuse, repair by an unauthorized person, or use of non-Yale replacement parts voids the guarantee and could lead to dangerous operation. For full Terms of Sale, see Sales Order Acknowledgment. Also, refer to the back cover for Limitations of Warranties, Remedies and Damages, and Indemnification and Safe Operation.
WARNING
ALTERATIONS OR MODIFICATIONS OF EQUIPMENT AND USE OF NON-YALE REPAIR PARTS CAN LEAD TO DANGEROUS OPERATION AND INJURY.
TO AVOID INJURY:
• DO NOT ALTER OR MODIFY EQUIPMENT.
• DO USE ONLY YALE PROVIDED REPLACEMENT PARTS.
OPTIONS Load Limiter
The Load Limited is a friction device that is designed and factory calibrated to prevent lifting excessive overloads. An excessive overload is indicated by lever movement without corresponding movement of the lower hook or load when the hoist is operated in the up direction. Should this occur, operate the lever in the down direction to remove the overload. Reducing the load to rated capacity or less will automatically restore normal operation. The Load Limiter can be ordered as part of a new lever hoist or in kit form that can be added to units now in service.
®
Anchor Sling (for 3/4 and 1-1/2 ton units only)
Anchor Sling is an upper hook extender that simplifies attachment when application or space limitation makes it impossible to pull in a straight line from hook to hook. A swiveling hook block is securely anchored to the housing and the upper hook swivels through a full 360°. Anchor Sling may be ordered as a feature of your new hoist or in kit form for simple installation on units now in use.
INSTALLATION
UNPACKING
After removing the hoist from the carton, check it for damage that may have occurred during shipment. If there is damage, refer to the packing slip envelope for claims procedure.
INSTALLATION
The RS2 Lever Hoist is designed for operation at ambient temperatures of 0° to 100° F (-17° to 38° C). It can be used in any position for pulling a load at an angle, horizontal pulling or vertical lifting, provided it is rigged to pull in a straight line from hook to hook and the frame is free to swivel on the upper hook.

WARNING
IF THE UNIT IS NOT RIGGED IN A STRAIGHT LINE, HOOK TO HOOK MANNER, AND IF THE FRAME IS NOT FREE TO SWIVEL, LEVER PULL MAY BREAK FRAME AND CAUSE PHYSICAL INJURY AND LOSS OF LOAD.
TO AVOID INJURY:
RIG THE UNIT IN A STRAIGHT LINE HOOK TO HOOK MANNER AND KEEP FRAME FREE TO SWIVEL - SEE FIGURE ON PAGE 3.
Regardless of how the hoist is used, make sure that the upper hook is firmly attached to a support or anchor that has sufficient strength to hold several times the rated load of the hoist.
H.Never operate the hoist when flammable materials or
vapors are present. Contact between metal parts may produce sparks that can cause a fire or explosion.
I. STAY ALERT! Watch what you are doing and use
common sense. Do not use the hoist when you are tired, distracted or under the influence of drugs, alcohol or medication causing diminished control.
WARNING
MALFUNCTION OF UNIT, RIGGING SLIP OR LOSS OF FOOTING MAY CAUSE USER TO SLIP RESULTING IN INJURY.
TO AVOID INJURY:
ALWAYS HAVE A FIRM AND SECURE FOOTING WHEN USING THE RS2 LEVER HOIST.
Using the upper hook, attach the hoist to support.
Be sure hoist is solidly held in the uppermost part of the hook arc and the latch is tightly against the hook tip.
WARNING
ATTACHING THE HOIST FROM AN INADEQUATE SUPPORT MAY ALLOW THE HOIST AND LOAD TO FALL AND CAUSE INJURY AND/OR PROPERTY DAMAGE.
TO AVOID INJURY:
MAKE SURE THE STRUCTURE HAS SUFFICIENT STRENGTH TO HOLD SEVERAL TIMES THE HOIST AND ITS RATED LOAD.
OPERATION
WARNING
IF NOT USED AS DIRECTED, HOIST MAY CAUSE INJURY.
TO AVOID INJURY:
USE ONLY AS DIRECTED BELOW. READ ALL INSTRUCTIONS BEFORE OPERATING THE RS2 LEVER HOIST.
GENERAL
A. The hoist must be kept clean to assure proper operation.
Before use, check to be sure the load chain is clean, that there is no foreign material in the liftwheel area and that the lever operates freely.
B. Do not load beyond the rated capacity. Overload can
cause immediate failure or cause damage resulting in future failure, even at less than rated capacity.
C.Do not use this hoist or any other material handling
equipment for lifting or moving people, or lifting loads over people.
D.Stand clear of all loads and warn other people of your
intention to move a load in their area. E. Do not leave a load on the unit unattended. F. Read warnings and instructions on the lever before each
use. G. Do not hold the load chain while operating the hoist.
Should the hoist not operate properly, serious injury
may occur.

FREE-CHAINING
WARNING
FAILURE TO PROPERLY USE THE FREE-CHAIN MECHANISM MAY CAUSE INJURY AND/OR PROPERTY DAMAGE.
TO AVOID INJURY:
USE THE FREE-CHAIN MECHANISMAS DIRECTED BELOW.
In this mode of operation, the gearing is disengaged to allow the chain to be easily pulled through the hoist by hand, for quick attachment to the load.
To free-chain the RS2 Lever Hoist:
1. Make sure there is no load on the lower hook.
2. Turn the lever trigger 1/4 turn from “UP” or “DN”.
3. Rotate the cam knob 1/4 turn clockwise (to right) from “OPERATE” to “FREE-CHAIN”. A “click” will be heard or felt and the cam cannot be rotated further in the clockwise position.
ATTACHING TO LOAD
Attach the lower hook to the load so that it is seated in the bowl of the hook and is not bearing against the tip of the hook, and the latch is tight against the hook tip.
4. Pull on hook side and loose end side of load chain to make sure chain feeds freely into and out of the hoist.
5. Grasp unit by frame or upper hook and pull on end ring or lower hook to pull the chain through hoist to the length required to attach lower hook to load. Pull on end ring to take-up slack in chain and THEN LET GO OF END RING.
6. Rotate the cam counterclockwise (to left) until the arrow points to “operate”.
WARNING
ALLOWING THE LOAD TO BEAR AGAINST THE HOOK LATCH AND/OR HOOK TIP CAN RESULT IN LOSS OF LOAD.
TO AVOID INJURY:
DO NOT ALLOW THE LOAD TO BEAR AGAINST THE HOOK LATCH AND/OR HOOK TIP. APPLY LOAD TO HOOK BOWL OR SADDLE ONLY.
Do not wrap the load chain around the load and hook onto itself as a choker chain sling or bring the load in contact with the hoist. Doing this will result in the loss of the swivel effect of the hook which could cause twisted chain and a jammed liftwheel. Also, the chain may be damaged at the hook. Make sure the upper and lower hooks are in a straight line and the frame is free to swivel on the upper hook. If the proposed use prevents straight line attachment, use an Anchor Sling (see page 1) or a chain sling to obtain a straight line pull.
WARNING
IF THE UNIT IS NOT RIGGED IN A STRAIGHT LINE HOOK TO HOOK MANNER, AND IF THE FRAME IS NOT FREE TO SWIVEL, LEVER PULL MAY BREAK FRAME AND CAUSE PHYSICAL INJURY AND LOSS OF LOAD.
7. Pull sharply on the loose end of chain and THEN LET GO OF CHAIN. Pull sharply on the lower hook side of chain, to make sure gearing is fully engaged.
WARNING
FAILURE TO FULLY ENGAGE THE GEARING WILL ALLOW LOAD TO RELEASE AND THUS CAUSE INJURY
TO AVOID INJURY:
AFTER ROTATING CAM KNOB TO “OPERATE”, PULL EACH CHAIN SHARPLY TO RE-ENGAGE GEARING AS DIRECTED ABOVE.
8. The hoist is now ready for operation. Move trigger to “UP” position and operate lever in and up and down motion to shorten the distance between hooks and thus pull or lift load. Only move the load enough to slightly load the hoist.
Check free-play of cam knob. The arrow tip should not move more than 3/16 inch (4.7mm). If movement is greater than this, move trigger to “DN” position and operate the lever to remove the load. Repeat step 7 and if the free-play is still more than 3/16 inch (4.7mm), the hoist should be disassembled to check for damaged or worn
parts. Do not take up the load chain to the point where the end ring or lower hook block becomes jammed against the frame.
TO AVOID INJURY:
RIG THE UNIT IN A STRAIGHT LINE HOOK TO HOOK MANNER AND KEEP FRAME FREE TO SWIVEL - SEE BELOW.

The hoist has been designed for hand powered operation only. Do not use an extension on the lever. Lever pulls of 45 pounds (21kg.) on the 3/4 ton unit, 55 pounds (25kg.) on the 1-1/2 ton unit and 62 pounds (28kg.) on the 3 ton unit will result in rated capacity on the unit. Any greater pull is an indication of either an overload or an incorrectly maintained unit.
TO LOOSEN OR LOWER LOAD
WARNING
POWER OPERATION MAY CAUSE STRUCTURAL
DAMAGE OR PREMATURE WEAR THAT IN TURN
MAY CAUSE A PART TO BREAK AND ALLOW THE
LOAD TO FALL.
TO AVOID INJURY:
OPERATE THE RS2 LEVER HOIST USING
HAND POWER ONLY!
As a result, the lever will move but, there will be no corresponding movement of the lower hook or load, when the unit is operated in the “up” direction. Should this occur, immediately move the trigger to the “DN” position and operate the lever until the overload is set down and removed from the unit. Reducing the load to rated capacity or less will automatically return the hoist to normal operation.
CAUTION: THE LOAD LIMITER IS SUBJECT TO OVERHEATING AND WEAR WHEN EXCESSIVELY OPERATED. FOR THIS REASON, WHEN AN OVERLOAD IS DETECTED, THE EXCESS LOAD MUST BE REMOVED AS QUICKLY AS POSSIBLE WITHOUT CONTINUED OPERATION OF THE LEVER.
Under certain conditions, such as applying an overload and removing it by external means, the brake may become “locked”. This results in not being able to operate the unit in the “down” direction. Should this occur, move the trigger to the “DN” position and give the lever a sharp pull and then additional strokes to lower the load and remove tension from the unit.
Move lever trigger to “DN” position. Again, operate lever in an up and down motion to increase the distance between hooks and thus loosen or lower the load.
Note that the cam is NOT changed when changing from “up” to “down” or from “down” to “up” operation.
WARNING
TURNING THE CAM WITH A LOAD ATTACHED WILL
ALLOW THE LOAD TO RELEASE AND MAY CAUSE
INJURY.
TO AVOID INJURY:
NEVER TURN THE CAM WHEN THE HOIST IS
UNDER LOAD.
INSPECT THE RS2 LEVER HOIST
Inspect the RS2 before each use and at specified intervals as directed in the inspection section (see next column).
LOAD LIMITER
The operation of a RS2 Lever Hoist equipped with a Load Limiter is the same as described above. In fact, as long as you are pulling or lifting loads that are within the rated capacity of the hoist, the Load Limiter will not function and you will not notice any difference in operation. However, if attempting to pull or lift load that is approximately 20% greater than rated capacity, the Load Limiter will function.
®
WARNING -
Use as directed above. Failure to do so may cause injury to you or others.
1. Do not exceed capacity shown on frame or lower hook block.
2. Do not use to lift people or loads over people.
3. Do not use unless the hoist’s frame and chain form a straight line between hooks.
4. Do not use if the frame is in contact with any object.
5. Do not use if the unit is damaged or malfunctions.
6. Do not use extension on lever. Use hand power only.
7. Do not use if chain is twisted, kinked or damaged.
TO AVOID INJURY:
MAINTENANCE
INSPECTION
To maintain continuous and satisfactory operation, a regular periodic inspection procedure must be initiated so that worn, damaged and missing parts can be replaced before the unit becomes unsafe. The frequency of inspection must be determined by the individual application.
The following list gives an inspection procedure for normal usage under normal conditions.
When the unit is subjected to heavy usage or dusty, gritty, moist or corrosive atmospheric conditions, shorter time periods must be assigned. Inspection must be made of all parts for unusual wear, corrosion or damage, in addition to those specifically mentioned in the schedule on page 5. Make certain that the unit is complete and contains all parts including hook latches and end ring.
Any parts that are deemed unserviceable must be replaced with new parts before the unit is returned to service. It is very important that the unserviceable parts be destroyed and properly disposed of to prevent their possible future use as a repair item. Use only Yale Hoist supplied repair parts as other parts may look the same but may not be to proper specifications.
4
Inspection of hoists is divided into two general classifications designated as “frequent” and “periodic”.
Frequent Inspections
Any hook that is twisted or has excessive throat opening indicates abuse or overloading of the unit. Other load­sustaining components of the hoist should be inspected for damage.
These inspections are by the operator or other designated personnel. Frequent inspections are to be performed daily or prior to each use and they are to include the following: A. Check for free movement of the lever, trigger and cam. B. Operate hoist with no load and check for visual signs or
abnormal noises that could indicate a potential problem. C. Check brake for evidence of slippage. D. Check chain for lubrication, wear damaged links or
foreign material (see page 6). E. Check hooks for damage, cracks, twist, latch
engagement and latch operation (see below). F. Check lever for bends, cracks and damage. G. Check support or anchor for damage.
Any deficiencies noted during the frequent inspections must be corrected before using the hoist.
Periodic Inspections
These are visual inspections by an appointed person who records conditions to provide a basis for a continuing evaluation of the hoist. Periodic inspections are to be performed semi-annually and they should include the following: A. All items listed under frequent inspections. B. Evidence of loose screws. C. Evidence of worn, corroded, cracked or distorted upper
and lower hook blocks, frame, end ring, hook block screws, covers, lever, suspension bolt, gears, bearings, pawls, pawl springs, cam, cam pins, lever cover, free­chaining spring, ratchet hub, stripper, Load Limiter (if equipped with same), ratchet and hoist hanger.
D. Evidence of worn, glazed or oil contaminated friction
discs. Friction discs should be replaced if their thickness is less than .075 inch (2 mm).
E. Warning label for legibility.
NOTE: To perform some of the periodic inspections, it is
necessary to partially disassemble the hoist. Refer to Disassembly-Assembly starting on page 7. Also, the external conditions may show the need for more detailed inspection which, in turn, may require the use of non-destructive type testing.
Any deficiencies noted during the periodic inspection must be corrected before using the hoist.
Hook Inspection
On latch type hooks, check to make sure that the latch is not damaged or bent and that it operates properly with sufficient spring pressure to keep the latch tightly against the tip of the hook and allow the latch to spring back to the tip when released. If the latch does not operate properly, it must be replaced. See previous illustration to determine when the hook must be replaced.
Replace Hook If Opening Is Greater Than 1-1/8” (28.5 mm) on 3/4 and 1-1/2 ton units or 1­15/16”(49.2mm) on 3 ton unit.
Replace Hook If Seat Is Less Than 21/32” (16.7 mm) on 3/4 and 1-1/2 ton units or 1-1/8” (28.5mm) on 3 ton unit.
On Latchlok type hooks, measure seat wear and throat opening as shown above and replace hook if measurements indicate the need to do same.
LOAD CHAIN
Chain should feed smoothly into and away from the hoist. If chain binds, jumps or is noisy, first clean and lubricate it (see below). If trouble persists, inspect chain and mating parts for wear, distortion or other damage.
Chain Inspection
First clean chain with a non-caustic/non-acid type solvent and make a link by link inspection for nicks, gouges, twisted links, weld spatter, corrosion pits, striations (minute parallel lines), cracks in weld areas, wear and stretching. Chain with any one of these defects must be replaced. Slack the portion of the chain that normally passes over the

Then measure stock diameter in the same area on a link that does not pass over the liftwheel (use the link adjacent to the end ring for this purpose). Compare these two measurements. If the stock diameter of the worn link is 0.010 inches (0.254mm), or more, less than the stock diameter of the unworn link, the chain must be replaced.

Vernier Caliper
When lubricating the chain, apply sufficient lubricant to obtain natural run-off and full coverage, especially in the interlink area.
LUBRICATION
Refer to Exploded View and Parts List pages 10 thru 13.
Measure
11 Pitches
Also check chain for stretch using a vernier caliper as shown above. Select an unused, unstretched section of chain (usually at the loose end) and measure and record the length over 11 chain links (pitches). Measure and record the same length on a worn section of chain. Obtain the amount of stretch and wear by subtracting the measurement of the unworn section from the measurement of the worn section. If the result (amount of stretch and wear) is greater than
0.145 inch (3.7 mm), the chain must be replaced.

WARNING
USING OTHER THAN YALE SUPPLIED LOAD CHAIN MAY CAUSE THE CHAIN TO JAM IN THE HOIST AND/OR ALLOW THE CHAIN TO BREAK AND THE LOAD TO DROP.
TO AVOID INJURY:
DUE TO SIZE REQUIREMENTS AND PHYSICAL PROPERTIES, USE ONLY HOISTALOY HOIST.
Use only a “Knife-Edge” caliper to eliminate possibility of false reading by not measuring full pitch length. Note that worn chain can be an indication of worn hoist components. For this reason, the hoist’s frame, stripper, and liftwheel should be examined for wear and replaced as necessary when replacing worn chain.
Also, the load chain is specially heat treated and hardened and should never be repaired.
IMPORTANT: Do not use replaced chain for other purposes such as lifting or pulling. Load chain may break suddenly without visual deformation. For this reason, cut replaced chain into short lengths to prevent use after disposal.

LOAD CHAIN IN THE RS2 LEVER
Chain Lubrication
A small amount of lubricant will greatly increase the life of load chain. Do not allow the chain to run dry. Keep it clean and lubricate at regular intervals with Lubriplate Chain Oil 10-R (Fiske Bros. Refining Co.) or equal lubricant. Normally, weekly cleaning and lubrication is satisfactory, but under hot and dirty conditions, it may be necessary to clean the chain at least once a day and lubricate it several times between cleanings.

WARNING
USING ANY GREASE OR LUBRICANT ON THE BRAKING SURFACES WILL CAUSE BRAKE SLIPPAGE AND LOSS OF LOAD CONTROL WHICH MAY RESULT IN INJURYAND/OR PROPERTY DAMAGE.
TO AVOID INJURY:
DO NOT USE ANY GREASE OR LUBRICANT ON BRAKING SURFACES. THE BRAKE IS DESIGNED
When lubricating parts adjacent to the brake, DO NOT use an excessive amount of lubricant which could seep onto the brake surfaces.
EXTERIOR FINISH
The exterior surface of the RS2 Lever Hoist has a durable, scratch resistant baked powder coating. Normally, the exterior surfaces can be cleaned by wiping with a cloth. However, if the finish is damaged, compatible touch-up paint can be purchased from Yale. Refer to page 13 for information on ordering paint.
PREVENTATIVE MAINTENANCE
A preventative maintenance program should be established to prolong the useful life of the hoist and maintain its reliability and continued safe use. The program should include frequent and periodic inspections (see page 5) with particular attention paid to lubrication of various components using the recommended lubricants (see Lubrication section for lubricating load chain and other parts).
RECOMMENDED SPARE PARTS
To insure continued operation, it is recommended that two friction discs (Key No. 673-13) be kept on hand at all times to replace friction discs that are worn, glazed or contaminated. Refer to page 12 for ordering information).
DISASSEMBLY

WARNING
CUTTING CHAIN CAN PRODUCE FLYING PARTICLES.
TO AVOID INJURY:
• WEAR EYE PROTECTION.
• PROVIDE A SHIELD, SUCH AS A HEAVY RAG, OVER THE CHAIN TO PREVENT FLYING PARTI­CLES.
TESTING
Prior to initial use, all altered or repaired hoists or hoists that have not been operated for the previous 12 months must be tested by the user for proper operation.
Test the unit first in the unloaded state and then with a light load of 50 pounds (23kg.) times the number of load supporting strands of load chain to be sure it operates properly and the brake holds the load when the lever is released; then test with a load of *125% of rated capacity. In addition, hoists in which load sustaining parts have been replaced shall be tested with *125% of rated capacity by or under the direction of an appointed person and a written report prepared for record purposes.
CUTTING CHAINS
Hoistaloy®load chain is hardened for wear resistance and is difficult to cut. However, the following methods are recommended when cutting a length of new chain from stock or cutting off a length of worn chain. (1) Use a grinder and nick the link on both sides, then
secure the link in a vise and break off with a hammer.
(2) Use a 7 inch(177.8mm) minimum diameter by 1/8 inch
(3.175mm) thick abrasive wheel (of type recommended by wheel supplier) that will clear adjacent links.
Cutting Chain by Nicking
(3) Chain may also be cut using a bolt cutter with special
jaws for cutting hardened chain (1 inch (25.4mm) long cutting edge).
*If unit is equipped with a Load Limiter, it may refuse to lift the 125% overload. Should this occur, reduce the test load to rated capacity. Also, on such units, the function of the Load Limiter should be checked. To do this attach the lower hook to a load of 180% of rated capacity and operate the unit in the “up” direction. When attempting to lift this load, the lever should slip. If it does not, the Load Limiter must be replaced. After this test, operate the unit in the “down” direction to remove tension in the chain.
NOTE: For additional information on inspection and testing, refer to the current issue of ASME B30.21 “Manually Lever Operated Hoists” obtainable from ASME Order Department, 22 Law Drive, Box 2300, Fairfield, NJ 07007-2300, U.S.A.
