Assembly Instructions:
This jack comes pre-assembled, except for the handle. The handle is
a two piece handle. Align the thru hole of the upper and lower
piece, and insert (2) M6 allen bolts. Align through hole on the three
position lock lever and insert Phillip screw.
Inspection:
Visual inspection should be made before each use of the service
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 accidentally 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:
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.
IMPORTANT!
Use only a good grade hydraulic fluid. Avoid
mixing types of oil. Do not use brake fluid, alcohol, glycerin,
transmission fluid, or dirty oil. Improper fluid can cause serious
internal damage to the jack, rendering it inoperative.
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 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 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.
