Remove any dirt accumulation and spray with a general purpose lubricant.

Hook Bearing

Apply a few drops of SAE 30 gear or motor oil around the edge of the bearing.

Idler Sheave Bearing (Bushing)

Disassemble load block and apply a light coat of NLGI #2 grease, or equivalent, inside of bearing.

HOIST REPAIRS

NOTE: If you do not have an experienced mechanic to do your repair work, we recommend that you send your hoist to an approved service station for repairs. Use authorized repair parts only.

1.For major repairs or when the hoist is to be sectioned in the suspension area, it will be necessary to move the hoist to a workbench or table.

Remove load and disconnect hoist from power supply before starting to do any repairs or to take any sections apart.

2.For repairs which can be done by removing the electrical cover only, the hoist need not be moved. Lowering the hoist to a convenient working level is desirable.

The following repair instructions will help you in understanding repair procedures, when related to the Replacement Parts List starting on page 16. For clarity these are broken down into areas.

Electrical Parts and Brake

Refer to Figures 9A, 9B & 16.

1.Remove the cover to access the controls. Single-phase models also have a starting switch and capacitor mounted on the motor as shown in Figure 13. The terminal blocks and end clamps snap off of the rails on the plate using a small screwdriver. DO NOT SLIDE THE END CLAMPS.

The reversing contactor can be slid off the rail, but it must be snapped on. Where the contactor fits the rail, one side has springs or pads that apply pressure against the edge of the rail. By pressing against that side at the base of the contactor, you can snap the part on or off using a rotating action. Note the numbers that label the terminals on the contactor and orient the part as shown in Figures 9A & 9B. Single-phase contactors have a small jumper that is not present on the 3-phase (note the 3 and 5 terminals on the reversing contactor in Figure 9A).

2.Remove the electrical panel by removing the stand-off screws (See Figure 16). The limit switch and brake are now accessible as shown in Figure 7.

3.Remove the transformer bolted to the back of the panel plate if it requires replacement.

4.Refer to Figure 15 to disassemble the brake. See BRAKE ADJUSTMENT on page 9 to properly set the brake.

5.Refer to Figure 17 to disassemble the limit switch.

See LIMIT SWITCH ADJUSTMENT on page 8 to properly set the upper and lower limits of travel.

6.Refer to Figure 18 for repairs on the pushbutton station. Also refer to the wiring diagram inside the electrical cover or Figures 9A and 9B for wiring instructions.

Figure 7 - Electrical Panel Removed

Motor

Refer to Figures 12, 13 and 14

The hoist motor is located on the opposite end to that of the electrical parts, but the two are tied together with electrical leads running through the housing.

1.If it is necessary to replace or repair the motor,

DISCONNECT THE HOIST FROM THE POWER SUPPLY and remove the electrical cover.

2.Loosen the screw clamps on the terminal blocks and reversing contactor to disconnect the motor leads (See Figure 16).

3.Remove the four motor mounting bolts attaching the motor to the housing. It will come loose at the motor coupling.

4.Inspect the motor coupling, motor shaft and all the bearings. Replace as necessary.

5.Install new or repaired motor according to the wiring diagram located inside the electrical cover or Figures 9A and 9B.

Gearing

Use the Replacement Parts List for Basic Hoist and Transmission Parts to help in repairs on gearing (See Figures 12 and 19). As disassembly is extensive for gearing, disconnect hoist and move to a workbench.

1.Remove electrical cover.

2.Remove electrical panel.

3.Remove brake assembly and limit switch assembly.

4.Drain oil from transmission.

Do not disassemble or readjust clutch, or replace with a clutch assembly from another hoist. Doing so will void the warranty and may create an unsafe condition. If replacement is needed due to wear or loss of adjustment, always use a new clutch assembly.
