NOTE: If you determine that a component failed as a result of hydraulic fluid contamination, replace the failed component and flush, fill, and bleed the hydraulic system.
Lift/Lower System No Lift - Motor Runs, No Codes Possible Cause
Action
Binding in lift mechanism or low system pressure
Check the lift pressure, if in bypass, inspect the mast, rollers, and rails. If lift pressure is low: 1. Measure the voltage to lift/lower solenoid. 2. Inspect the L/L solenoid for binding. 3. Replace the pressure relief. 4. Replace the lift pump.
No Lift - Motor Does Not Run, No Codes Possible Cause
Action
Open in cables to lift motor or bad motor
Test for B+ to the D terminal at the lift motor with the the lift contactor closed. Test for B- to the A terminal at the lift motor. If voltage is present, replace the motor. If voltage is not present, inspect cables and contactor tips.
Slow Lift or No Lift - Empty, Motor Runs Possible Cause
Action
Binding in lift mechanism or low system pressure
Check the lift pressure, if in bypass, inspect the mast, rollers, and rails. If lift pressure is low: 1. Measure voltage to lift/lower solenoid. 2. Inspect L/L solenoid for binding. 3. Replace the pressure relief. 4. Replace the lift pump.
