MODEL 520-3003

PRIOR TO OPERATION

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 by rotating handle 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
product, checking for leaking hydraulic fluid and damaged,
loose or missing parts. Each jack must be inspected by
a manufacturer's repair facility immediately, if acciden-
tally 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 recom-
mended that an annual inspection of the jack be made by
a manufacturer's authorized repair facility and that only
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 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,
and with jack in the upright position, remove oil filler plug.
Fill until oil is just below 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 en-
tering the system. Replace with proper oil.

3 Ton Speedy Lift Service Jack
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 correctly positioned. Raise
load to desired height. Place jack stands of appropri-
ate capacity under the vehicle. DO NOT CRAWL UN-
DER VEHICLE WHILE LIFTING VEHICLE OR PLAC-
ING OR REMOVING JACK STANDS! Place jack
stands at vehicle manufacturer's recommended lift ar-
eas 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 mecha-
nism of the jack.
LUBRICATION
All moving joints require lubrication often. Remove
handle and grease the bottom and of handle where it
connects to the release valve.
