TROUBLESHOOTING:
PROBLEM: The lift will not operate or operates slowly.
Possible Causes:
Bad Ground—Verify the ground end of the Vehicle Harness is touching the vehicle frame in an area that is free of
paint and corrosion. If the lift does not have a good ground, the motor will not run under full power and will affect the
lifting capacity and the speed in which it operates. This can be tested by attaching a test harness to a fully charged
shop battery that is not on a vehicle and running the lift.
Battery—Check to see if the battery needs to be replaced or if the terminals are corroded. Clean the terminals if any
corrosion is present. 12 volts should be present at the lifting or rotational motors from the vehicles battery. This can
be tested with a voltage meter.
PROBLEM: Intermittent power to the lift. The lift will operate for a short period of time and quit. At a later time it will
start working again.
Possible Causes:
Circuit Breaker—Although the breaker resets itself automatically, it may be malfunctioning and need to be replaced.
Check for power at the lift with a test lamp.
Bad Ground—Verify the ground end of the Vehicle Harness is touching the vehicle frame in an area that is free of
paint and corrosion. If the lift does not have a good ground, the motor will not run under full power and will affect the
lifting capacity and the speed in which it operates. An intermittent ground will cause the lift to lose power. This can
be tested by attaching a test harness to a fully charged shop battery that is not on a vehicle and running the lift.
Hand Control—Test by bypassing the hand control. Do this for only a second or two. The lift, vehicle, scooter or
chair may be damaged if continuous power is left supplied to the unit.
PROBLEM: Lifting arm is slow to swing in / out. (AL400 only)
Possible Causes:
Dirty Bushings—Clean and apply new grease to the white plastic bushing that is located in the Base.
Bad Ground—Verify the ground end of the Vehicle Harness is touching the vehicle frame in an area that is free of
paint and corrosion. If the lift does not have a good ground, the motor will not run under full power and will affect the
lifting capacity and the speed in which it operates. This can be tested by attaching a test harness to a fully charged
shop battery that is not on a vehicle and running the lift.
PROBLEM: The lifting strap operates in reverse.
Possible Causes:
The lifting strap was overextended. The lifting strap was lowered too far, causing the strap to wind around the spool
backwards. Lower the strap until it unravels from the spool. Then, raise the strap in the proper direction.
PROBLEM: AL400 rotates in wrong direction when installed on the passenger side of the vehicle.
Possible Causes:
The lift is shipped from the factory to be mounted on the drivers side of the vehicle. To change the rotation for the
passenger side remove the bolt located near the bottom of the post, rotate the motor 180 degrees and reinsert the
bolt. Next, change the rotation of the motor located in the base by switching the wires on the motor to reverse the po-
larity.
PROBLEM: The scooter or chair tips to the front or back while it is being lifted.
Possible Causes:
The scooter or chair is being lifted off center. The docking device should center the lifting strap over the center of
gravity which is generally around the center of the seat. Check to make sure the proper docking device is being used.
