purging the Hydraulic ram

NOTe: Before first using this tool, the hydraulic ram must be purged.

1.  To purge the Ram, first raise the Jack to its uppermost position, with no load. 

2.  When the Jack has been raised, remove the Filler Bolt  from the Hydraulic 

Cylinder. Keeping your hands and tools clear, press the Foot Pedal down to 
attempt to raise the jack even higher. 

3.  When it is clear the Jack will not raise any higher, release the Foot Pedal.

4.  Add good quality hydraulic oil into the opening in the Cylinder where the 

Filler Bolt has been removed. Fill until the Cylinder will hold no more oil. 

5.  Replace the Filler Bolt and its Seal Washer into the Cylinder, tighten firmly. 

Lower the Jack by pressing the ReLeASe portion of the Foot Pedal.

6.  Check the condition of the Hydraulic Lift Table before each use. Raise and 

lower it several times before adding any load. Be sure that all controls work 
properly, and that it raises and lowers smoothly.

Operating the rolling bridge jack

 

nOtice: this jack is not to be used for any aircraft purpose.

1.  Observing all safety precautions, drive the work vehicle over the Rolling Bridge 

Jack. Shut off the engine, put the vehicle in gear or park, and set the parking 
brake.

2.  Connect your air hose to the male air quick-release adapter. Check that your 

air pressure regulator is set between 90 and 120 PSI.

3.  Roll the Jack along its rails until it is positioned properly under the vehicle.

4.  Pull out each Adjustable Arm Assembly (4) to position the Lift Pad (1) where 

desired under the vehicle. 

cAutiOn:

 Check with the vehicle manufacturer to 

determine approved lift points for each vehicle. Never attempt to lift a vehicle 
using unapproved lift points, or if the lift points are damaged or weakened by 
rust. Damaged or improper lift points may cause the vehicle to suddenly fall 
off the jack potentially causing serious personal or property injury.
