INSPECTION
Visual inspection should be made before each use of the jack, checking for leaking hydraulic fluid and damaged, loose or missing
parts. 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.
SETUP
1.
Depress the upper handle lock in the upper handle while simultaneously inserting the end of the upper handle in the lower handle. Rotate
the upper handle back and forth until the handle lock seats in the hole in the lower handle lock hole
.
2. Grease the inside of the handle yoke so the handle will rotate freely inside the yoke. Remove the handle yoke screw. Insert the end of the lower
handle all the way in the handle yoke until it engages the release valve assembly. Secure the handle in the handle yoke by reinstalling the handle
yoke screw and tightening the screw. Rotate the handle to see if it is rotating the release valve assembly. Pull on the handle to make sure it is
secured in the handle yoke. If the release valve assembly is not rotating and/or the handle pulls out of the handle yoke, repeat step 2.
3.
IMPORTANT:
In most cases the jack should work normally right out of the box but it is not unusual for air to get trapped in the jack’s hydraulic
system during shipping and handling. There are several symptoms of an air trapped hydraulic system which include only partial incremental
pump stroke, jack will not lift load, jack will not sustain load or pumping feels spongy under load. The following procedure will purge air from the
hydraulic system and only needs to be done if experiencing the above mentioned conditions.
a) Close the release valve by turning the handle clockwise until it stops. Now turn the handle in a counterclockwise direction two full
revolutions. Pump the jack 10 full incremental pump strokes.
b) Rotate the handle in a clockwise direction until tight and pump the lift arm to maximum height without a load. If the pumping condition has
improved, repeat steps a) and b) until all the air has been purged from the system.
CAUTION:
In order to prevent seal damage and jack failure, never use alcohol, hydraulic brake fluid, or transmission oil in the jack. Use
hydraulic jack oil, a light turbine oil, Chevron Hydraulic Oil AW ISO 32 or Unocal Unax AW 150.
IMPORTANT: Before attempting to raise any vehicle, check vehicle service manual for recommended lifting surfaces.
