Clean all bright and moving parts with a thin film of oil and grease.
Store the stacker in a dry, frost-free, dust-free environment.
Do not use plastic sheeting to cover the stacker. Condensation can occur.
Additional operations for vehicles with integral electrical systems
Disconnect the batteries from the stacker’s electrical system.
Charge the batteries.
Clean the top of the battery case and terminals.
Check the electrolyte level and top off as necessary. Not required for maintenance-free or gel batteries.
Recharge the batteries every 90 days and every 6 months for gel batteries.
Spray a suitable contact spray on unattached electrical contacts.
Return to service
Thoroughly clean and grease the stacker
Remove the film of protective grease
Check the hydraulic fluid tank and hydraulic fluid for condensation. If necessary, change the fluid.
Inspect hydraulic hose lines for brittleness.
Verify all the vehicle functions are performing as expected.
Troubleshooting
Before performing troubleshooting tasks, set the stacker on blocks so all the wheels clear the floor.
Problem
Possible Causes
Action
Unit will not

Charger
malfunction
Bad batteries
Verify output voltage on charger. There will be a voltage reading when
connected to the batteries. It should be approximately 28 volts.
Load test the batteries.

raise or motor
does not
run
Loose Wire
Bad solenoid

discharged
Verify 24 volts at the coil when raise button is depressed. If voltage is
not present, trace wiring back until a short or open is found.
If voltage is present at the solenoid and the unit does not rise, remove
the two wires to the coil and measure the coil’s resistance. It should be
about 19 ohms. Replace coil as needed.
Bypass the upper limit switch and see if the forks rise. DO NOT TAKE
THEM ALL THE WAY UP. If it does rise, verify the limit switch is
normally closed and will open when activated. If the limit switch is ok,
adjust the switch until the fork height is 7 to 8 inches.
Check fuses above the motor controller.
Charge the batteries.
