OPERATION - JACK
Before using your jack:
1.Turn release valve counter-clockwise to open. Pump jack handle
about 6 full strokes to assure complete distribution of hydraulic fluid.
(See Figure 1)
To raise:
Place pump handle over release
valve and turn clockwise to close.
Make certain that load is on
center of saddle. Insert handle into handle sleeve and pump to raise
load to desired height. Transfer load to jack stands or other
appropriate supports before working under load. (See figure 2)
To lower:
Raise load enough to remove jack
stands. Slowly turn release valve
counter-clockwise just enough to
allow controlled descent.
(Never turn counter-clockwise
more than 3 full turns)
1. When jack is not in use, lifting arm and handle sleeve should be in
fully down position to keep their machined surfaces free from
corrosion.
2. Keep jack clean and well lubricated at points illustrated in figure 3.
3. For best results, use only hydraulic fluid with a rating of SAE 10 for
refills. Check fluid level with jack in fully down position. Fluid level
should be up to bottom of oil fill plug. (See figure 5)
4. Regularly check for loose, worn
or damaged parts and repair
or replace as necessary.
5. Replace worn or damaged
parts with Performance Tool
replacement parts. Be sure
that only qualified personnel
perform repairs.
