BEFORE ATTEMPTING TO RAISE ANY VEHICLE,
CHECK VEHICLE SERVICE MANUAL FOR
RECOMMENDED LIFTING POINTS.
OPERATION:
1. To Raise Load:
Close release valve tightly by
twisting Handle clockwise.
DO NOT OVERTIGHTEN.
Position jack under load so that saddle will contact
load firmly and load is centered so it cannot slip.
Operate jack handle 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!
1. Place jack stands at vehicle manufacturer’s
recommended lift areas that provide stable support
for the raised Vehicle. Once jack stands are
positioned, open the release valve VERY SLOWLY
(by twisting the Handle counter clockwise.)
Lower the load to rest on the jack stands. Then,
make sure that the release valve on the jack is
closed tightly (twist the Handle clockwise).
2. To lower load:
Re-check to make sure release
valve is tightly closed (twist the Handle clockwise).
Then, operate the jack handle until the load is raised
enough to remove the jack stands.
Once jack stands are removed, open release valve very
slowly to lower the vehicle (twist the Handle counter
clockwise). Lower jack completely so that the vehicle is
securely resting on the ground and that jack no longer
makes contact with vehicle.
Keep hands or feet away from the hinge mechanism
of the jack.
MAINTENANCE
When adding or replacing hydraulic fluid, always use a
quality hydraulic fluid. DO NOT use brake fluid, alcohol,
detergent motor oil, dirty oil or any fluid other than quality
hydraulic fluid. Improper fluids can cause internal
damage to the jack and improper or unsafe operation.
ADDING HYDRAULIC FLUID
With the saddle fully lowered and the jack on level
ground, remove the filler screw. Hydraulic fluid should be
filled to the level of the filler screw hole. If the level is
below this hole, add hydraulic fluid as needed.
LUBRICATION
All moving joints require lubrication often. Lightly grease
saddle post and saddle bottom. Remove handle and
grease the lower end of handle where it rotates in the
handle socket. Oil all lift arm linkages, front wheels and
rear casters.
PROBLEM ACTION
