All Columbus McKinnon (CM®) Lodestar Electric Chain Hoists are thoroughly inspected and performance tested prior to shipment. If any properly maintained hoist develops a performance problem due to a material or workmanship defect, as verified by CM, repair or replacement of the unit will be made to the original purchaser without charge. This repair/replacement policy applies only to Lodestar Hoists installed, maintained and operated as outlined in this manual, and specifically excludes parts subject to normal wear, abuse, improper installation, improper or inadequate mainte­nance, hostile environmental effects and unauthorized repairs/modifications.
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-CM replacement parts voids the guarantee and could lead to dangerous operation. For full Terms of Sale, see Sales Order Acknowledgement. Also, refer to the back cover for Limitations of Warranties, Remedies and Damages, and Indemnification and Safe Operation.

SERVICE STATIONS
1. NOT lift people.
2. NOT allow people on unsecured load without fall protection.
3. NOT exceed rated capacity of hoist.
4. NOT remove or obscure any capacity or warning label.
5. Check the supporting structure. The connection between the load hook and structure. The load itself and the connection between the hoist support and the load for their ability to withstand the loads imposed with an adequate design factor.
6. Tie off the load with auxiliary chains or cables before access to the area beneath the load is permitted. As an alternative, the system may be designed such that malfunction or failure of one hoist’s load bearing components does not cause load loss and/or overloading of any other hoists in the system. Note that in such a system, hoist performance and function must be monitored visually or with use of load cells.
7. Read hoist manual and special instructions before installing and operating the hoist.
Successful Theatrical Hoist Operation Requires the following actions:
At the loose end, maintain a minimum of 24 inches of chain freely hanging over the side of hoist.
Keep load chain well lubricated using Lubriplate® 10R Bar and Chain oil.
Do make sure hoist is phased properly and chain travel limits function properly.
If a chain container is used, inspect before each use for damaged, loose hardware and water drainage provisions. Make certain container attachment hardware has an adequate design factor of a minimum of 5 to 1. Also, make sure chain container is of sufficient capacity: chain chain in fully loaded container shall not exceed 75% of container height.
1. Maintain a firm footing or be otherwise secured when operating the hoist.
2. Check brake function by tensioning the hoist prior to each lift operation.
3. Use hook latches. Latches are to retain slings, chains, etc. under slack conditions only.
4. Make sure the hook latches are closed and not supporting any parts of the load.
5. Make sure the load is free to move and will clear all obstructions.
6. Avoid swinging the load or hook.
7. Make sure hook travel is in the same direction as shown on the controls.
8. Inspect the hoist regularly, replace damaged or worn parts, and keep appropriate records of maintenance.
9. Use CM parts when repairing the unit.
10. Lubricate load chain per instructions in this manual.
11. NOT
use the hoist load limiting or warning device to measure load.
12. NOT use limit switches as routine operating stops. They are emergency devices only.
13. NOT allow your attention to be diverted when operating hoist.
14. NOT allow the hoist to be subjected to sharp contact with other hoists, structures, or objects through misuse.
15. NOT adjust or repair the hoist unless qualified to perform such adjustments or repairs.
SAFETY PRECAUTIONS
Each Entertainment-Lodestar Electric Hoist is built in accordance with the specifications contained herein and at the time of manufacture complied with our interpretation of applicable sections of the *American Society of Mechanical Engineers Code B30.16 “Overhead Hoists”, the National Electrical Code (ANSI/NFP A70), the Occupational Safety and Health Act, British Health Safety Executives, TUV and CE Directive. Since OSHA states the National Electrical Code applies to all electric hoists, installers are required to provide current overload protection and grounding on the branch circuit section in keeping with the code. Check each installation for compliance with the application, operation and maintenance sections of these articles.
The safety laws for elevators, lifting of people and for dumbwaiters specify construction details that are not incorporated in CM industrial hoists. For such applications, refer to the requirements of applicable state and local codes, and the American National Safety Code for elevators, dumbwaiters, escalators and moving walks (ASME A17.1). Columbus McKinnon Corporation cannot be responsible for applications other than those for which CM equipment is intended.
*Copies of this Standard can be obtained from ASME Order Department, 22 Law Drive, Box 2300, Fairfield, NJ 07007-2300, U.S.A.
THIS SYMBOL POINTS OUT IMPORTANT SAFETY INSTRUCTIONS WHICH IF NOT FOL­LOWED COULD ENDANGER THE PERSONAL SAFETY AND/OR PROPERTY OF YOUR­SELF AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL AND ANY PROVIDED WITH THE EQUIPMENT BEFORE ATTEMPTING TO OPERATE YOUR LODESTAR HOIST.

HOOK SUSPENSIONS
Swivel and rigid type hook suspensions (see Figure 1) are available for all Lodestar Electric Hoists. However, swivel type hook suspensions are normally recommended for most applications.
UNPACKING INFORMATION
When received, the hoist should be carefully inspected for damage which may have occurred during shipment or han­dling. Check the hoist frame for dents or cracks, the external cords for damaged or cut insulation, the control station for cut or damaged enclosure, and inspect the load chain for nicks and gouges. If shipping damage has occurred, refer to the packing list envelope on the carton for claim procedure.
Before using the hoist, make sure the voltage change board (Key# 627-1013) is connected for the intended power supply the hoist is to be operated.
NOTE: To assure long life and top performance, be sure to follow the load chain lubricating instructions on page
11.
INSTALLING THE SUSPENSION
A. Single Reeved Units:
Remove the hook suspension from its carton and the two suspension screws. Place the suspension assembly into the recess on top of the hoist so that the adapter body follows the contour of the hoist. Insert the suspension screws through the holes in the adapter and hand thread these into the self locking nuts enclosed in the hoist. The screws will turn freely into the nuts until the last 1/4” (6.35 mm) of travel, during which the resistance of the nut locking collar will be encoun­tered. Securely tighten the screws to the recommended seat­ing torque (see Table 2) using a 12 point socket (½” (13mm) socket) which fits the head of the screw.
LATCHLOK®HOOKS
CM’s Latchlok hooks (see Figure 2) are available to replace the standard upper and lower hooks used on the Lodestar Electric Hoists.
B. Double Reeved Units:
Remove the hook suspension from its carton and the two suspension screws, dead end pin, washer and cotter pin. It should be noted that the suspension includes a dead end bolt and block for supporting the dead end of the load chain as shown in Figure 7.
Place the suspension assembly into the recess on top of the hoist. The dead end block should project through the bottom of the hoist with the pin hole and slot aligned to the under­side of the hoist as shown in Figure 7. If these are not aligned as shown, lift the head of the bolt from the hex recess in the adapter and turn the bolt and block assembly and reseat the bolt head to obtain the proper alignment. Do not change the position of the dead end block on the bolt to attain this alignment.
Check the position of the pin hole in the dead end block to make sure it has not been disturbed from its factory setting. The distance from the top of the pin hole to the bottom of the hoist should not exceed 7/16” (1 1.11 mm) for the Models R and RR. If the distance is not correct, adjust the position of the dead end block to obtain the proper distance (see Page 21).

Now, insert the suspension screws through the holes in the adapter and hand thread these into the self locking nuts enclosed in the hoist frame. The screws will turn freely into the nut until the last 1/4” (6.35mm) of travel during which the resistance of the nut locking collar will be encountered. Securely tighten the screws to the recommended seating torque (see Table 2) using a 12 point socket which fits the head of the screw.
The dead end of the load chain is temporarily positioned (a few links from the end) by a wire tie. Do not remove this tie before attaching the chain to the dead end block. (See Fig.7).

ATTACHING LOAD CHAIN
The Model R & RR are shipped with the dead end of the load chain temporarily connected to the bottom of the hoist by a wire tie (1) as shown in Figure 7. The clip is located a few links from the end of the chain, and it should not be removed until the chain is to be attached to the dead end block (2). To attach the chain to the dead end block, proceed as follows:
1. Suspend the hoist from an adequate support.
2. The hoist is shipped with the dead end of the load chain temporarily positioned a few links from the end by a light wire clip (1) as shown in Figure 7. Do not remove this clip until the chain is secured.
3. Remove the clip (1) by inserting a screw driver blade through a chain link and levering against the bottom of the hoist. Slide the contact block up the chain until it is against the bottom of the hoist and the dead end block is projecting through the square opening in the bottom of the block. Insert the last link of the load chain, making sure there are no twists between the hook block and the dead end block, into the dead end block. Push the contact block up slightly and secure the load chain to the dead end block using the dead end pin, washer and cotter pin furnished with the suspension. The dead end pin also supports the contact block (See Figure 8).
4. Do not remove the wire ties from the load chain at this time.

WWAARRNNIINNGG
Using other than CM supplied high strength suspension screws to attach the suspension adapter to the hoist may cause the screws to break and allow the hoist and load to fall.
TO AVOID INJURY:
Use only the CM supplied suspension screws to attach the suspension to the hoist and hand torque these screws to the recommended seating torque as specified above.
DO NOT apply any type of lubricant to the threads of these screws. Lubricating the threads will reduce the effort to seat the screws and as a result, tightening the screws to the above recommended torque may break the screw, damage the sus­pension adapter, strip the nuts and/or damage the hoist frame.

POWER SUPPLY AND ELECTRICAL CONNECTIONS
The hoist should be connected to a branch circuit which com­plies with the requirements of the National Electrical Code and applicable local codes.
It is recommended, especially for a single phase hoist with a one horsepower motor (.746 Kilowatts), that a line of ade­quate capacity be run directly from the power supply to the hoist to prevent having problems with low voltage and circuit overloads.
For grounding of the hoist, the power cord includes a ground­ing conductor (green yellow, G-Y). Before connecting the hoist to the power supply, check that the power to be used agrees with the position of voltage change plug on the volt­age change board. The nominal hoist voltage rating corre­sponding to the voltage range given on hoist identification plate is:
THREE PHASE HOIST
Unless ordered on a special basis, all single speed dual volt­age (230/460-3-60, 220/380-3-50 and 220/415-3-50) hoists are factory arranged to operate on 460-3-60 (or 380-3-50 or 415-3-50). However, a voltage change board is provided to easily and quickly change from 460 to 230 (or 380 to 220 or 415 to 220) volt operation. The voltage change board shown in Figure 12 is located in the hoist as shown in Figure 13.
Voltage change board is located under back frame cover (1) for Models B, C & F and under motor housing cover (2) for Models J, L, R, LL and RR.
The voltage change board is color coded to indicate high and low volt connections. Connecting the 9 and 12 pin plugs into the “Red” voltage change board recepticles will connect the hoist for high voltage (380-3-50, 415-3-50 or 460-3-60). To change the hoist voltage to low voltage (208-3-60, 220-3-50 or 230-3-60) simply remove the 9 and 12 pin plugs from the “Red” recepticles and insert same into the “White” recepticles located on the voltage change board. Be sure to make a notation of the new hoist voltage on the tag attached to the power cord.
PROPER PHASING
Since the motor in a three phase hoist can rotate in either direction, depending on the manner in which it is connected to the power supply, the direction of hook movement must be checked prior to each usage.
NOTE: Serious damage can result if the hook is run to the upper or lower limit of travel with the hook operating in a direction opposite to that indicated by the control sta­tion. Therefore, proceed as follows:
1. Make temporary connections at the power supply.
2. Operate
(UP) control momentarily. If hook raises,
connections are correct and can be made permanent.
3. If hook lowers, it is necessary to change direction by inter changing the Blue lead and the Black lead of hoist power cord at power supply. Under no circumstances should the internal wiring of the control device or hoist be changed to reverse hook direction. The wiring is inspected and tested before leaving the factory.

Do not force the Lodestar Protector to compensate for improperly adjusted limit switches or reverse voltagephasing.
CHECKING FOR TWIST IN LOAD CHAIN Models R, RR
The best way to check for this condition is to run the lower hook, without a load, up to within about 2 feet (.61 Meters) of hoist. If the dead end of the chain has been properly installed, a twist can occur only if the lower hook block has been cap­sized between the strands of chain. Reverse capsize to remove twist.
CHECKING FOR ADEQUATE VOLTAGE AT HOIST
The hoist must be supplied with adequate electrical power in order to operate properly. For proper operation, the voltage, (measured at the hoist end of the standard power cord with the hoist operating in the , up direction with full load) must be as indicated in the table below.
SIGNS OF INADEQUATE ELECTRICAL POWER (LOW VOLTAGE) ARE:
Noisy hoist operations due to brake and/or contactor
chattering.
Dimming of lights or slowing of motors connected to
the same circuit.
Heating of the hoist motor and other internal compo-
nents as well as heating of the wires and connectors in the circuit feeding the hoists.
Failure of the hoist to lift the load due to motor stalling.
Blowing of fuses or tripping of circuit breakers.
To avoid these low voltage problems, the hoist must be con­nected to an electrical power supply system that complies with the National Electrical Code and applicable local codes. This system must also provide (slow blow fuses or inverse­time type circuit breakers) and provisions for grounding the hoist.
Low voltage may also be caused by using an undersized cord and/or connectors to supply power to the hoist. The fol­lowing chart should be used to determine the size wires in the extension cord in order to minimize the voltage drop between the power source and the hoist.
Remember, operation with low voltage can void the CM repair/replacement policy. When in doubt about any of the electrical requirements, consult a qualified electrician.
WWAARRNNIINNGG
Allowing the hook block to run into the bottom of the hoist when raising a load or allowing the chain to become taut between the loose end screw and the frame when lowering a load may break the chain and allow the load to drop.

TTOO AAVVOOIIDD IINNJJUURRYY::
Always disconnect the power cord from the power supply system and lockout/tagout disconnecting means before servicing the hoist. Working in or near exposed energized electrical equipment presents the the danger of electric shock.
CHECKING LIMIT SWITCH OPERATION IF HOIST IS EQUIPPED
Operate hoist over the entire length of its rated lift, checking upper and lower limit switches for correct operation as follows:
1. Press (UP) control and raise the lower hook until top of hook block is about one foot (.30 M) below the hoist.
2. Cautiously continue raising the hook until the upper limit switch stops the upward motion. The upper limit switch is set at the factory to stop the hook block 6 inches (152 mm) from the bottom of all hoists.
3. If adjustment is necessary, see page 12.
4. Press (DOWN) control and cautiously lower hook until lower limit switch stops the downward motion. Maintain a minimum of 24” (610 mm) of chain freely hanging over the side of the hoist.
5. If adjustment is necessary, see page 12.
NOTE: If the hoist is equipped with a chain container/bag, reset the upper and lower limit switches as indicated on page 12.
Under no condition should the hook block or load be permitted to come in contact with the chain container/bag. If contact is made, the function of the chain container can be interfered with and its fasterners imperiled. NOTE:
When chain bag is filled to capacity the bag must be no more than 75% filled.
GENERAL
1. The Protector is designed to allow the intermediate gear to slip on an excessive overload. An overload is indicated when the hoist will not raise the load. Also, some clutching noise may be heard if the hoist is loaded beyond rated capacity. Should this occur, immediately release the (UP) control to stop the operation of the hoist. At this point, the load should be reduced to the rated hoist capacity or the hoist should be replaced with one of the proper capacity. When the excessive load is removed, normal hoist operation is automatically restored.
CAUTION: The Protector is susceptible to overheating and wear when slipped for extended periods. Under no circumstance should the clutch be allowed to slip for more than a few seconds.
Due to the above, a hoist equipped with a Protector is not rec­ommended for use in any application where there is a possi­bility of adding to an already suspended load to the point of overload. This includes dumbwaiter (*see below) installa­tions, containers that are loaded in mid-air, etc.
(*) Refer to limitations on Page ii concerning dumbwaiter applications.
Also, if a Lodestar Hoist with a Protector is used at unusual extremes of ambient temperatures, above 66°C (150
0
F), or below -9°C (15°F), changes in lubricant properties may per­mit the hoist to raise larger loads than under normal operat­ing conditions and presents possibility of damage or injury.
2. With hoists that are equipped with an adjustable screw
limit switch, the limit switch will automatically stop the hook at any predetermined point when either hoisting or lowering.
OPERATING INSTRUCTIONS HOIST
1. Check to ensure that the load point is in line with the hoist
head.
2. WHEN APPLYING A LOAD, IT MUST BE DIRECTLY
IN LINE WITH HOIST. AVOID OFF-CENTER LOADING OF ANY KIND.
3. Take up a slack load chain carefully and start load easily
to avoid shock and jerking of hoist load chain. If there is any evidence of overloading, immediately lower the load and remove the excess load.
4. Do not allow the load to swing or twist while hoisting.
5. Do not allow the load and/or attachments to bear against
the hook latch.
SAFETY PROCEDURES
For safety precautions and a list of Do’s and Do Not’s for safe operation of hoists, refer to page i.
1. When preparing to lift a load, be sure that the attachments
to the hook are firmly seated in hook saddle. Avoid off center loading of any kind, especially loading on the point of hook.
2. When lifting, raise the load only enough to clear the floor
or support and check to be sure that the attachments to the hook and load are firmly seated. Continue lift only after you are assured the load is free of all obstructions.
3. Do not load hoist beyond the rated capacity shown on
hoist identification plate or on the hoist motor housing cover, Models B, C & F and on hoist back frame cover, Models J, L, R, LL & RR. Overload can cause immediate failure of some load-carrying part or create a defect causing subsequent failure at less than rated capacity. When in doubt, use the next larger capacity of CM
Lodestar Hoist.
4. Do not use this or any other overhead materials handling
equipment for lifting persons.
5. Warn personnel of your intention to lift a load in the area.
Tie off the load with auxiliary chains or cables before access to the area beneath the load is permitted.
6. Permit only competent personnel to operate unit.
7. Do not wrap the load chain around the load and hook onto
itself as a choker chain.
Doing this will result in:
a. The loss of the swivel effect of the hook which could
result in twisted chain and a jammed lift wheel.
b. The upper limit switch, if so equipped, is by-passed
and the load could hit the hoist.
c. The chain could be damaged at the hook.
8. Before lifting load, check for twists in the load chain. Atwist
can occur if the lower hook block has been capsized between the strands of chain. Reverse the capsize to
remove twist.
WWAARRNNIINNGG
Allowing the hook block to run into the bottom of the hoist when raising a load or allowing the chain to become taut between the loose end screw and the frame when lowering a load may break the chain and allow the load to drop.

9. On single reeved chain hoist used in conjuction with head blocks and ground support systems. Check for twists between the hoist and head block. Twisted load can result in a jammed liftwheel.
10.Do not allow the load to bear against the hook latch. The latch is to help maintain the hook in position while the chain is slack before taking up slack chain.
1 1.T ake up a slack load chain carefully and st art load easily to
avoid shock and jerking of hoist load chain. If there is any evidence of overloading, immediately lower the load and remove the excess load.
12. Do not allow the load to swing or twist while hoisting.
13. Never operate the hoist when flammable materials or vapors are present. Electrical devices produce arcs or sparks that can cause a fire or explosion.
14.STAYALERT! 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.
To maintain continuous and satisfactory operation, a regular inspection procedure must be initiated to replace worn or damaged parts before they become unsafe. Inspection inter­vals must be determined by the individual application and are based on the type of service to which the hoist will be subject­ed and the degree of exposure to wear, deterioration or mal­function of the critical components.
The type of service to which the hoist is subjected can be clas­sified as “Normal”, Heavy”, or “Severe”.
Normal Service: Involves operation with randomly distributed loads within the rated load limit, or uniform loads less than 65 percent of rated load for not more than 25 percent of the time.
Heavy Service: Involves operating the hoist within the rated load limit which exceeds normal service.
Severe Service: Normal or heavy service with abnormal operating conditions.
Two classes of inspection - frequent and periodic - must be performed.
Frequent Inspections: These inspections are visual exami­nations by the operator or other designated personnel. Records of such inspections are not required. The frequent inspections are to be performed monthly for normal service, weekly to monthly for heavy service, and daily to weekly for severe service, and they should include those items listed in Table 4.
Periodic Inspections: These inspections are visual inspections of external conditions by an appointed person. Records of periodic inspections are to be kept for continuing evaluation of the condition of the hoist.
Periodic inspections are to be performed yearly for normal service, semi-annually for heavy service and quarterly for severe service, and they are to include those items listed in Table 5.
CAUTION: Any deficiencies are to be corrected before the hoist is returned to service. Also, the external condi­tions may show the need for disassembly to permit a more detailed inspection, which, in turn, may require the use of nondestructive type testing.
PREVENTIVE MAINTENANCE
In addition to the above inspection procedure, a preventive 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 the periodic and fre­quent inspections with particular attention being paid to the lubri­cation of the various components using the recommended lubricants (see page 11).
HOOK INSPECTION
Hooks damaged from chemicals, deformations or cracks, or that have more than a 10
o
twist from the hook’s unbent plane, excessive opening or seat wear must be replaced. Also, hooks that are opened and allow the latch to not engage the tip must be replaced. Any hook that is twisted or has excessive throat opening indicates abuse or overloading of the unit. Inspect other load sustaining parts, hook block screws, load pins and hook block bodies for damage.
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 should be replaced. See Figure 14 to determine when the hook must be replaced.
WWAARRNNIINNGG
Allowing the load to bear against the hook latch and/or hook tip can result in loss of load.
TTOO AAVVOOIIDD IINNJJUURRYY::
Do not allow the load and/or attachments to bear against the hook latch and/or hook tip. Apply load to hook bowl or saddle only.

LOAD CHAIN
Chain should feed smoothly into and away from the hoist or hook block. 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 splatter, 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 if the chain that normally passes over the lift­wheel. Examine the interlink area for the point of maximum wear (polishing, see Figure 15). Measure and record the stock diameter at this point of the link. Then measure stock diameter in the same area on a link that does not pass over the liftwheel (use the link adjacent to the loose end link for this purpose). compare these two measurements. If the stock diameter of the worn link is 0.010 inches (0.254 mm), or more, less than the stock diameter of the unworn link, the chain must be replace.
On double reeved units, repeat this examination of the chain that passes through the hook block.
Also check chain for stretch using a vernier caliper as shown in Figure 16. Select an unused, unstretched section of chain (usually at the lose end) and measure and record the length over 11 chain links (pitches). Measure and record the same length on a worn section of the chain. Obtain the amount of stretch and wear by subtracting the measurement of the worn section. If the result (amount of stretch and wear) is greater than 0.145 inch (3.7mm), the chain must be replaced.
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 chain guide, hook block and liftwheel should be examined for wear and replaced as necessary when replacing worn chain.
Also, these chains are specially heat treated and hardened and should never be repaired.

IMPORT ANT:
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.

Use of commerical or other manufactures’ chain and parts to repair Lodestar Hoists may cause load loss.
TTOO AAVVOOIIDD IINNJJUURRYY::
Use only factory supplied replacement load chain and parts. Chain and parts may look alike, but factory original chain and parts are made of specific materials or processed to achieve specific properties. See Figure 17.

PROTECTOR
The Protector should operate for the normal life of the hoist without service. The device has been lubricated and calibrated at the factory for a specific model of hoist and is not adjustable or interchangeable with other models. For proper overload pro­tection, be sure before installing a Protector that it is correct for the unit. The spring washer of the Protector had been color coded at the factory as follows:
HOIST LUBRICATION GEARS
NOTE: To assure extra long life and top performance, be
sure to lubricate the various parts of the Lodestar Hoist using the lubricants specified below. If desired, these lubricants may be purchased from CM. Refer to page 29 for information on ordering the lubricants.
The Protector should operate for the normal life of the hoist without service. The device has been lubricated and calibrated at the factory for a specific model of Lodestar Hoist and is not adjustable or interchangeable with other models.
CAUTION: The Protector is to be used with “Century Lubricants HB-1 1 #3” grease. Do not use any other grease or the Protector will not operate properly and parts could be damaged.
The gears and Protector (627-327 and 627-328) are packed at assembly with grease and should not need to be renewed unless the gears have been removed from the housing and degreased.
CAUTION: Never degrease the Protector or attempt to disassemble this device. Degreasing the Protector may damage parts and using a device that has been degreased may cause erratic, inconsistent operation. If the Protector has been degreased, it must be replaced by a factory calibrated device.
If the gears are removed from the housing, wipe the excess grease off the outside surfaces of the Protector with a soft cloth and degrease the remaining gears and housings. Upon reassembly, add 7 oz. of the above grease to gears and hous­ing. Also, coat the spline on the end of the drive shaft (627-311) with a Molydisulphide lubricant such as “Super Herculon”.
For Models LL, and RR, see page 22 for special gearing align­ment instructions.
The limit switch gears are of molded nylon and require no lubrication.
Apply a light film of machine oil to the limit switch shaft threads (627-220, page 28) at least once a year.
BEARINGS
All bearings and bushings, except the lower hook thrust
bearing, are pre-lubricated and require no lubrication. The lower hook thrust bearing should be lubricated at least once a month.
CHAIN GUIDES, LIFTWHEELAND LOWER SHEAVE WHEEL
When the hoist is disassembled for inspection and/or
repair, the chain guides, lower sheave wheel (on double
chain units) and liftwheel must be lubricated with . . . .
Lubriplate Bar and Chain Oil 10-R (Fiske Bros. Refining Co. or equivalent) prior to reassembly. The lubricant must be applied in sufficient quantity to obtain natural runoff and full coverage of these parts.
LOAD CHAIN
Asmall 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 Bar and Chain Oil 10-4 (Fiske Bros. Refining Co.) or equal lubricant. Normally, weekly lubrication and cleaning 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.
When lubricating the chain, apply sufficient lubricant to obtain natural run-off and full coverage, especially in the interlink area.
ELECTRIC BRAKE ASSEMBLY
The correct air gap between armature and field, when brake is not energized, is 0.025 inch (.635mm) and need not be adjusted until the gap reaches 0.045 inch (1.143mm). When checking brake gap, always reset to .025 inch (.635 mm).
To adjust the brake, proceed as follows:
1. Disconnect hoist from power supply.
2. Remove back frame cover, see figure 13
3. Before adjusting the gap: a) back off the stud nuts
and examine friction linings and friction surfaces for excessive wear (min. thickness .188 inch, 4.78mm), scoring or scoring or warpage. b) Check shading coils to be sure they are in place and not broken. A missing or broken shading coil will cause the brake to be noisy when hoist is operated. Any of these symptoms indicate the need for replacement parts.
