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 and lowering it fully,
checking for proper operation, BEFORE RETURNING THE JACK TO OPERATION.
DO NOT USE A DAMAGED OR MALFUNCTIONING JACK!
