3. If the batteries and circuit board appear in order, no air leak is found and no fault is
found with the wiring
•
Proceed to check that the lift motor is functioning by removing the motor and battery
leads and running jumper cables from the motor leads to the battery leads. (Reversing
polarity causes the motors run in reverse)
4. If the batteries and circuit boards appear in order, no air leak is found and no fault is
found with the wiring or with the motor
•
The most likely cause of failure is a blown fuse on the circuit board. To confirm, check
the fuse on the board and verify that it is operable. If a fuse is blown replace it with
another fuse 25 amp fuse and test the lift. Under no circumstances should a fuse with a
fuse rating other than the specified amperage be used. Using such a fuse can result in
damage to the lift and /or personal injury. If the problem persists after testing, replace
the circuit board. If the problem still persists contact
your local Vancare distributor.
•
The other likely cause of failure is a circuit board failure that is not readily visible. To
confirm, connect the non-functioning lift to a board from service parts or from another
lift. (There is no need for a complete board installation: the replacement board used for
confirmation can be hooked up provisionally outside the lift.)
2. If the Up/Down buttons on the hand control and/or lift; or the lift emergency lowering
do not work
•
Check the Emergency Shut-Off Switch. If it has been activated during an emergency,
call customer service. If it has been activated accidentally turn the switch to the “ON”
position. This will allow you to operate the lift again. If the lift still fails to operate
examine the Emergency Shut-Off switch to make sure it is not obstructed and activates
and deactivates the lift. If the problem persists, replace the Emergency Shut-Off switch.
