BEFORE USE
Air may become trapped in the hydraulic system during transit.
To purge air:
1. Open release valve by turning knob counterclockwise.
2. Pump pedal rapidly 4 full strokes. This will expel air that may
have entered hydraulic fluid passages during transit.
3. Close release valve by rotating knob clockwise and pump
foot pedal.
4. If hydraulic arm raised, jack is ready for use. If not, repeat
this procedure.
INSPECTION
Visual inspection should be made before each use
of the transmission 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
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 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
IMPORTANT: When adding or replacing hydraulic fluid,
always use a quality hydraulic fluid. DO NOT use brake fluid,
alcohol, glycerine, detergent motor oil, or dirty oil as improper
fluid can cause serious internal damage to jack.
Regularly lubricate all moving parts with SAE 30 oil or light
grease, paying close attention to the tilt screws and related
linkages.
Regularly check the oil level in ram. With saddle fully lowered
and jack on level ground, remove filler plug. Hydraulic fluid
should be filled to level of hydraulic fluid filler plug 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.
