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:
Turn release valve clockwise to close.
Make certain that load is on center of
saddle. Pump the jack handle to raise
load to desired height. Never exceed the rated load value.
Transfer load to jack stands provided, use in pairs ONLY. Always
use appropriate supports before working under load. (See figure 2)
To lower:
Raise load slightly 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 precision machined surfaces free
from corrosion.
2. Keep jack clean and well lubricated. (See 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 5mm below filler hole. (See figure 5)
4. Regularly check for loose, worn or damaged parts and repair or
replace as necessary.
5. Replace worn or damaged parts
w i t h P e r f o r m a n c e To o l

only qualified personnel perform
repairs.
