Controller Replacement

When experiencing problems with the hydraulic functions, the controller may not be at fault. ALWAYS troubleshoot to verify the component(s) at fault before replacing the controller. Refer to the section ZAPITM Controllers 2200YRM1064, ZAPITM Controllers 2200YRM1006, or ZAPITM Controllers 2200YRM1067 for your lift truck for additional information on the ZAPITM display and for information on troubleshooting fault codes, adjusting parameters, and testing the ZAPITM motor controller.

Remove:

1. Move lift truck to a safe, level area.

NOTE: Some new controllers may have software upgrades which will not allow previous controller parameters and settings to be transferred.

2. If possible, prior to replacing the controller, note all special customer parameters and settings.

3. Turn the key switch to the OFF position.

4. Disconnect and separate the battery connectors.

5. Block drive tire to prevent movement. See the section Periodic Maintenance 8000YRM1048, Periodic Maintenance 8000YRM1009, or Periodic Maintenance 8000YRM1379 for your lift truck.

NOTE: If removing the entire control panel assembly to include the electrical panel plate, it will be necessary to perform Step 6. If only removing the controller, contactor, horn, fuses, or wires, it is not necessary to perform Step 6. See Figure 6 or Figure 7.

Electrical System Checks

NOTE: On some models, the dash indicator will display the code: EP 107 (or a higher number) for 1 to 2 seconds every time the key switch is turned to the ON position. This code represents the EEPROM software version and DOES NOT INDICATE A FAULT CODE.

NOTE: These checks require a volt-ohmmeter. Specific checks require additional equipment.

NOTE: The correct meter polarity is necessary for the checks. The voltage checks are made between the individual points and battery negative. Connect the meter negative to battery negative.

Block lift truck so the drive wheels are off the floor. See the section Periodic Maintenance 8000YRM1048, Periodic Maintenance 8000YRM1009, or Periodic Maintenance 8000YRM1379 lift trucks. Refer to How to Put a Lift Truck on Blocks.

Turn the key switch to the OFF position.

Disconnect and separate the battery connectors.

Remove the upper drive unit compartment cover.

Remove the lower drive unit compartment cover.

Discharge the capacitor. See Special Precautions.

Turn the key switch to the OFF position.

Remove the upper drive unit compartment cover.

Remove the lower drive unit compartment cover.

Remove the four capscrews from the two-piece shield over the MDU and remove the shields.

Caster Wheels Replacement

WARNING: Put blocks under both forks and on both sides of the drive tire. The blocks must prevent the lift truck from falling and causing personal injury or property damage.

NOTE: The caster wheel does not have to be removed from the lift truck frame to replace the wheel or the wheel axle.

Raise the drive wheel off the floor. Block the lift truck. See How to Put a Lift Truck on Blocks.

Remove the lock nut retaining the wheel on the wheel axle. Drive the wheel axle out of the arms and remove the wheel.

Align the wheel between both arms and install the wheel axle. Install the nut on the wheel axle. Tighten the nuts to 34 to 47 N•m (25 to 35 lbf ft).

Remove the blocks from under the lift truck and lower the truck to the floor.

Test the operation of the truck prior to returning the truck to service.
