1.
FEATURES & MODELS
The Borum Air Actuated Hydraulic Bottle Jack is designed to operate either manually or pneumatically
for lifting and lowering, but not sustaining load. This 50,000kg 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 (See Below).
