General Safety Information (Continued) 13. Do not allow weight of load to rest on hook latch or the tip of the hook. 14. When lifting do not exceed the maximum rated load limit of the hoist. Structural s and load attaching devices must have a load rating equal to or greater than that of the hoist.
15. When moving a load be certain that the pathway is free of any obstructions. 16. Make certain that all persons are warned of an approaching load and that all persons remain clear of a suspended load. Never lift loads over people or leave a load unattended when suspended.
17. When operating hoists always maintain a firm footing and keep your attention focused.
22. Always make repairs or adjustments to damaged or malfunctioning hoists before using. 23. Allow qualified persons only to make repairs or adjustments. 24. Make regular inspections, and keep maintenance records. NOTE: Any damage, malfunction, or unusual change in performance should be reported promptly.
Before beginning a work shift an operator should test the pushbutton station, limit switches and brake control. If not operating properly, they should be replaced or repaired before putting hoist in service.
INSTALLATION OF CHAIN CONTAINER ASSEMBLY See Figures 2A, 2B. 1. Remove screw, nut and washer from the suspension frame (see Fig. 2A).
Installation 1. ing structure and load attaching devices should have a load rating at least equal to that of the selected hoist.
2. Place chain container bracket flush against the suspension frame. Replace washer, nut and screw. Tighten securely (see Fig. 2B).
Hoists must be installed in locations which provide safe operating conditions. Do not use in areas that contain explosive dust, gases, or vapors. Do not use in or near wet areas or outdoors. Make certain that the operator and other persons have room to stand clear of the load at all times.
3. Run load hook down to its lowest position. Place the slack end of the chain in chain container. Feed the remainder of chain into container by operating hoist in the "UP" direction to the top limit. This will permit chain to pile freely and eliminate possibility of jamming which may occur if chain is placed in container by hand.
18. Keep load centered under hoist to avoid any swinging of load.
Avoid use of hoist in areas or applications where slack chain hanging from hoist may create hazardous conditions.
19. If slack occurs, take up carefully. Check load balance and lift a few inches. Then check for load holding action before continuing to lift.
2. The power supply to the hoist should be 115V, single phase, 60 Hz. The voltage can range from plus or minus 10% of 115V.
20. Limit switches should only be used as an emergency device. Do not use for routine stops unless recommended.
3. The hoist is equipped with a 3-prong, grounding plug. Make sure that it is plugged into a properly grounded and installed receptacle.
21. Do not use the loading limiting device to measure a load.
4. After hanging the hoist make sure that the hook latch closes.

General Safety Information (Continued) LIMIT SWITCH OPERATION It is important to check for the proper operation of the limit switches before using the hoist. 1. Press UP button. 2. While hook moves up, raise the limit switch paddle where the chain enters the hoist. 3. Hook should immediately stop. 4. Check DOWN limit switch in similar manner. Do NOT use hoist when brake is not properly working. If hook does not stop within 1 or 2 inches after pushbutton is released, the brake assembly may need to be replaced.
Operation The hoist should be used on an intermittent basis only. Total usage per hour should not exceed fifteen minutes. A thermal cut-off protects the motor from overheating and will also automatically reset it once the motor has sufficiently cooled, so that its operation can be resumed. 1. The hoist should be positioned directly over load. Do NOT attempt to side pull. 2. Hoist chain should not be wrapped around load. Use proper slings. 3. Engage hook with load. Before lifting load make sure load is seated properly.
4. After lifting load clear of its s, stop to check braking action. 5. Avoid jogging the controls or making quick reversals when lifting or lowering a load. 6. Do not use the limit switch for routine stops during normal operation. It should be used as an emergency device. 7. Stand away from load at all times.
Maintenance
any significant repairs or any operating occurrence leading one to suspect that the hoist's capacity may have been impaired. Make certain load is removed from hoist before attempting to service. Also, before attempting to service or remove any components, make certain power supply is disconnected. If power disconnect point is out of sight, lock it in the open position and tag to prevent any unexpected application of power. Only a qualified electrician or service person should perform any electrical troubleshooting or maintenance.
INSPECTION Inspection procedures are listed under three general classifications based upon intervals at which inspection should be performed – daily, quarterly, and annually. Deficiencies should be carefully examined and corrected. The intervals between inspections can vary due to conditions. If the hoist is used under adverse conditions, it should be inspected more often. A planned inspection routine should be established for this hoist based upon frequency, severity of use, and environmental condition. (Reference ASME Standard B30.16). Some inspections should be made frequently (daily to monthly) and others periodically (monthly to yearly). It is strongly recommended that an inspection and Maintenance Check List and an Inspector's Report, similar to those shown in Fig. 6A and 6B, be used and filed for reference. All inspections should be performed or overseen by a designated inspector. Special inspections should be made following
DAILY INSPECTION 1. Inspect the following items every day before operating hoist: a. Check pushbutton station, brake, and limit switches for proper operation. b. Check hooks for deformities, cracks, or chemical damage. Hooks having more than 1-inch opening at throat (see Fig. 3) should be replaced. c. Inspect hook once daily for cracking, extreme wear or spreading. Replace hooks showing any of these signs. If the throat openings are spread wider than the maximum permissible 15% increase listed in Fig. 3, the hooks have been overstressed and must be replaced. Any hook that is bent or twisted more than 10 degrees from the plane of an unbent hook must also be replaced (see Fig. 3). d. Check for open, bent or damaged hook latches. ®

NOTE: Maximum permissible throat opening of hook with latch fully retracted. QUARTERLY INSPECTION
e. Check for worn brake disc by measuring the brake air gap with a feeler gauge. Brake gap larger than the allowable wear limit may cause chatter or failure to release (see Figure 4).
b. Check for loose nuts, bolts, and screws. c. Inspect for worn, corroded, cracked, or distorted parts. d. Check electrical parts, upper and lower limit switches, and pushbutton station. ANNUAL INSPECTION 3. Inspect the following items every year: a. Check items listed under daily and quarterly inspection. b. Check hooks for cracks by means of a magnetic particle test or other crack detecting test.
3. Check overall wear by selecting an unused length of chain and comparing it to a used length. a. Let unworn chain hang vertically with a light load (about 20 pounds) on it to remove slack. b. Measure outside length of a convenient number of links with large caliper.
NOTE: Do not use near flammable liquids or hazardous materials of any kind.
c. Measure same number of links in used section of chain and calculate difference in numbers.
BRAKE REPAIR
d. If length of worn chain is more than 1-1/2% longer than unused chain – chain should be replaced.
When brake does not operate properly as described in installation section, replace entire brake assembly.
2. Inspect the following every 90 days: a. Check items listed under daily inspection.
wear to the link diameter. If any are worn to less than 0.175", the chain must be replaced.
Keep brake surface and brake lining free of grease.
Check for worn brake disc by measuring the brake air gap with a feeler gauge (see Fig. 5). Brake gap larger than the allowable wear limit may cause chatter or failure to release. CHAIN INSPECTION Chain is to be kept clean and lubricated. Visually check chain every time hoist is used. Hoist must not be operated when chain is twisted or kinked. An important phase of hoist maintenance is chain inspection. Check individual link and check for elongation. 1. Check all links for gouges, nicks, weld spatter, and distortion. 2. Inspect and measure each link for
4
IMPORTANT: Chain is designed specially for use with hoist. Do not substitute any other make or type of chain. Never attempt to weld or splice hoist load chain.
TO REPLACE CHAIN 1. Remove lower hook block and chain and ball (Fig. 7, Ref. No. 17). 2. Line up end to end — new chain with old chain — so link welds match. (Welds toward outside of sheave). 3. Use a piece of string or small wire to tie chains together so ends are exactly 9/32" apart. This enables the chain to smoothly through hoist. 4. Operate enough to pull new chain into hoist. Refit springs (Ref. No. 6), lower hook (Ref. No. 86), and end ball (Ref. No. 59).
