OPERATING INSTRUCTIONS
IMPORTANT:
Before attempting to raise a vehicle, check vehicle service manual for
recommended lifting surfaces.
1. To raise load: Close release valve tightly (by turning handle knob clockwise).
DO NOT
OVERTIGHTEN.
Position jack under load so that saddle will contact load firmly and load is
centered so it cannot slip. Operate the air valve until saddle approaches the load. Once again
check to see that saddle is correctly positioned. Raise load to desired height. Place jack stands of
appropriate capacity under the vehicle.
DO NOT CRAWL UNDER VEHICLE WHILE
LIFTING VEHICLE OR PLACING OR REMOVING JACK STANDS!
Place jack stands at
vehicle manufacturer’s recommended lift areas that provide stable support for the raised vehicle.
2. To lower load: Open release valve VERY SLOWLY (by turning handle knob
counterclockwise). When release valve is opened, saddle and load will be lowered. Lower the
vehicle slowly so as not to shock load the jack stands. Once repairs are completed, raise vehicle
enough to remove jack stands. Lower vehicle very slowly.
CAUTION:
Keep hands or feet away from the hinge mechanism of the jack.
MAINTENANCE INSTRUCTIONS
IMPORTANT!
Use only a good grade hydraulic jack oil. Avoid mixing types of oil. Do
not use brake fluid, alcohol, glycerin, detergent motor oil, or dirty oil. Improper fluid
can cause serious internal damage to the jack, rendering it inoperative.
To Add Oil:
With saddle fully lowered and ram depressed, set jack in an upright
position and remove oil filler plug. Fill until oil is level with filler plug hole.
To Change Oil:
For best performance and longest life, replace the complete oil supply
at least once a year. To drain the oil, remove the filler plug. Lay the jack on its side
and allow the oil to run out into suitable drain pan. The oil will run slowly because air
must enter as oil drains out. Be careful to prevent dirt or foreign matter from entering
the system. Replace with proper oil.
LUBRICATION
All moving joints require lubrication often. Remove handle and grease the lower end of
handle where the release mechanism rotates in the handle socket.
