Visual inspection should be made before each use of the
bottle jack, checking for abnormal conditions such as dam-
aged, 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 man-
ufacturer’s authorized repair facility. It is recom-
mended that an annual inspection of the bottle 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.

IMPORTANT:
When adding or replacing hydraulic fluid,
always use a quality hydraulic fluid (NAPA 765-1541) or
equivalent). DO NOT use brake fluid, alcohol, glycerin,
detergent motor oil, or dirty oil as improper fluid ccan
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 vent screw 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.

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 capac-
ity 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 mecha-
nism of the jack.
