Visual inspection should be made before each use of the jack, checking for leaking hydraulic fl uid and 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 manu-
facturer’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 specifi ed parts.
A list of authorized repair facilities is available from
the manufacturer.

Description
Model 6603 service jack is a self-contained device designed for lifting, but not sustaining, a partial vehicular
load. It consists of a frame with wheels and swivel casters supporting a mechanism that actuates a pivoting
lift arm equipped with a saddle. It is designed for use by professional auto mechanics.
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 oil passages during transit.
3. Close release valve by rotating handle clockwise and pump handle.
4. If lift arm raises to full height, jack is ready for use. If not, repeat this procedure or follow the
troubleshooting instructions provided.
