befOre Use
iMpOrtant! befOre Using this JacK:
The breather located below hole in cross plate must be opened. Insert
slotted screw driver through hole and turn breather screw counter clockwise until it stops
turning. Do not force screw past stopping point.
Air may become trapped in the hydraulic system during transit. To purge air:
1. Open release valve by turning handle counterclockwise.
2. Pump handle rapidly 4 full strokes. This will expel air that may have entered
hydraulic fluid passages during transit.
3. Close release valve
pump handle.
4. If lift arm raises to full height, jack is ready for use. If not, repeat this procedure or
follow trouble shooting instructions provided.
inspectiOn
Visual inspection should be made before each use of the jack, checking for leaking
hydraulic fluid and damaged, loose or missing parts. Each jack must be inspected
by a manufacturer's repair facility immediately, if subjected to an abnormal load or
shock. Any jack which appears to be damaged in any way, found to be badly worn,
or operates abnormally MUst be reMOved frOM service
until necessary repairs are made by a manufacturer's authorized repair facility. It is
recommended that an annual inspection of the jack be made by a manufacturer's
authorized repair facility and that any defective parts, decals or warning labels be
replaced with manufacturer's specified parts.
A list of authorized repair facilities is available from the manufacturer.
Maintenance
IMPORTANT: When adding or replacing hydraulic fluid, always use a quality hydraulic
fluid (NAPA 765-1541 or equivalent). DO NOT use brake fluid, alcohol, glycerine,
detergent motor oil, or dirty oil as improper fluid can cause serious internal damage
to jack.
To add hydraulic fluid: With saddle fully lowered and jack on level ground,
remove breather. The hydraulic fluid should just cover the surface of the
internal cylinder visible through the hole. Do not overfill. Replace breather. If
low, add hydraulic fluid as needed.
Maintenance and Inspection: The owner and/or user must maintain and inspect the
jack in accordance with the manufacturer's instructions.

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 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/ 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
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.
and
lUbricatiOn
All moving joints require lubrication on a regular maintance schedule. Remove handle
and grease the lower end of handle where it rotates in the handle socket. Using a
grease gun, lubricate the lift arm pivot shaft grease fitting until grease appears at the
end of the shaft. Grease all lift arm linkages, front wheels and rear casters.
