ASSEMBLY, OPERATION & PREVENTATIVE MAINTENANCE
1.
FEATURES
The TradeQuip Air Actuated Hydraulic Bottle Jack is designed to operate either manually or pneumatically for lifting and
lowering, but not sustaining load. This 12,000kg Heavy-Duty Air/Hydraulic Bottle Jack is the perfect choice for a wide variety
of uses. The power of air makes it easy to lift farm vehicles, trucks, lawn mowers, heavy equipment and other large loads. The
manual function allows for normal operation anywhere, even without an air supply.

BEFORE USE
Conduct a thorough visual inspection checking for any abnormal conditions, such as cracked welds, and damaged, loose, or
missing parts. Bleed any trapped air from the hydraulic system by performing the air bleeding procedure below.
Bleed Air from Hydraulic System:
During transit the unit may become "air-bound", causing a spongy ram action. To bleed the hydraulic system;
1.
Remove the Oil Filler Bung and if required, refill with *32 Grade hydraulic oil until the
oil is lapping the bottom of the Oil Filler Hole then replace the Oil Filler Bung.
2.
Start with the Pump Socket Assembly in the horizontal position and turn the
Release Valve ‘clockwise’ to the lifting position.
3.
With the Jack on its base, pull the Pump Socket upwards to the raised position.
4.
Invert the Jack and push the Pump Socket back to the horizontal position.
5.
Place the Jack back on its base to test the Pump Socket for firmness.
6.
Repeat steps 4 to 6 until the Pump Socket feels firm and the Lift Ram is extending
consistently.
7.
At this point the Pump Assembly should be bled of air.
8.
Follow steps 8 to 9 to bleed the Lift Ram.
9.
Ensure the Jack is back on its base and make sure the Release Valve is in the ‘clockwise’
raise mode, then pump the Pump Socket until the Lift Ram is fully extended.
10.
Invert the Jack and then turn the Release Valve ‘anti-clockwise’ to the lowering position.
Carefully hold the Jack in the inverted position until the Lift Ram is fully retracted. If
necessary apply force to the bottom of the Jack to return the Lift Ram back to fully
retracted position.
At this point both the Manual Pump and Lift Ram should now be free of air and the Jack ready for Air Motor bleeding
