Bleeding the Hydraulic Cylinders
Bleeding the Hydraulic Cylinders removes air from the Hydraulic System. Air in the Hydraulic System
will cause the Lift to operate erratically. It may cause one frame to rise faster than the other, you may
experience noises, shaking, or jerking while raising and lowering. This does not damage the QuickJack
or the Hydraulic Cylinders, but it is not the normal smooth operation you should experience.
Important: Read and understand this entire Bleeding Procedure before you begin.
⚠
WARNING You must always wear OSHA-approved (publication 3151) Personal Protective
Equipment when handling hydraulic components and fluid: eye protection and
gloves are mandatory.
Important: The frames may rise while performing this operation. Never raise the
frames above 6 inches / 152 mm without weight on the frames!
To bleed the Hydraulic Cylinders, you will need:
• One
3/16 " hex key (Allen ® key) to loosen and tighten the Bleed Screws
• Rags or a catch container for the hydraulic fluid expelled around the Bleed Screws.
•
While this procedure may be accomplished by one person, an assistant may minimize hydraulic
fluid waste by closing the bleeding screws while you operate the QuickJack control.
Do not put a Vehicle on the QuickJack Frames when bleeding the Hydraulic Cylinders.
To bleed the QuickJack’s Hydraulic Cylinders
