BEFORE USE
Air may become trapped in the hydraulic system during transit.
To purge air:
1. Open release valve by turning release valve control knob
counterclockwise.
2. Pump handle rapidly 6 full strokes. This will expel air that
may have entered hydraulic fluid passages during transit.
3. Close release valve by turning the release valve control
knob clockwise and pump handle.
4. If lift arm raised, jack is ready for use. If not, repeat this
procedure.
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, is 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.
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 release
valve control 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 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!
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 release valve control 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
IMPORTANT: When adding or replacing hydraulic fluid,
always use a quality hydraulic fluid. 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 filler plug. Hydraulic fluid should be filled
to level of hydraulic fluid filler plug hole. 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.
LUBRICATION
All moving joints require lubrication often. Using a grease
gun, grease the lift arm pivot shaft grease fitting until grease
appears at the end of the shaft. Oil all lift arm linkages, front
wheels and rear casters.
