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 4.
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
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.

OPERATION
Before using your jack:
Insert lower bar section into handle sleeve.
(See Fig. 1) Secure bar to handle sleeve with

about 6 full strokes to assure complete distri-
bution of hydraulic fluid. (See Fig. 2)
To raise:
Turn bar clockwise to close release valve.
Make certain that load is on center of saddle.
Pump to raise load to desired height. Transfer
load to jack stands or other appropriate supports
before working under load. (See Fig. 3)
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)
