Troubleshooting
TO PREVENT SERIOUS INJURY: Use caution when
troubleshooting a malfunctioning jack. Stay well clear of the
supported load. Completely resolve all problems before use.
If the solutions presented in the Troubleshooting guide do not solve the problem, have a qualified
technician inspect and repair the jack before use.
After the jack is repaired: Test it carefully
without a load by raising it and lowering it fully, checking for proper operation, BEFORE
RETURNING THE JACK TO OPERATION.
DO NOT USE A DAMAGED OR MALFUNCTIONING JACK!
