supplying Air pressure to the rolling jack

Pressurized air supplied  to the Foot Pedal / Hydraulic Pump Assembly (26) 
is converted to hydraulic pressure. The hydraulic pressure passes through the 
Hydraulic Hose (33) and activates the Hydraulic Ram (12). The Hydraulic Ram 
activates the Scissor Assembly (15 and 16) which in turn lifts the Top Strut (10) 
with its Saddles (3). This operation will lift your vehicle or other work item.

1.  The Foot Pedal / Hydraulic Pump 

Assembly  (26)  is  supplied  with  a 
male quick-release air adapter, as 
shown in the photo. 

2.  Attach your air hose with a suitable 

female  quick-release  air  adapter 
to  this  male  adapter.  Adjust  your 
air supply pressure to 90-120 PSI. 

cAutiOn:

 Do not exceed 120 PSI, 

as this may damage the jack.

3.  To operate the Rolling Bridge Jack, 

press down on the lower portion of 
the pedal marked “PUMP”. The jack 
will begin to rise. To lower the jack, press on the portion of the pedal marked 
“ReLeASe”. The jack will begin to lower. 

 

wArning: Keep feet, hands any part of your body, any other person or 

animal or any equipment away from the scissor Assembly (15 and 16) 
when raising or lowering this jack. severe personal or property injury 
may result from items being pinched in the scissors assembly or related 
components during operation of this jack.

4.  The air hose used should be of good quality, and in good condition. The air hose 

should be routed to the jack in a way that will not cause a tripping hazard. The 
air hose should not be allowed to be near the scissor assembly. The air hose
