NOTE: Do the BLEEDING HYDRAULIC

SYSTEM procedure in this manual

with the following step.

 POWER DOWN LIFTGATES: Raise the platform to bed height. Disconnect both

bottom POWER DOWN RETURN HOSES at the “T” connector between pump

box and bottom of each cylinder. (Refer to POWER DOWN HYDRAULIC LINES

IDENTIFICATION in this manual. Place a large container to catch ﬂ uid from both

hoses. Set control box toggle switch to UP position to raise platform. Check if ﬂ uid

is streaming from the hoses. A few drops of hydraulic ﬂ uid is okay; however, if ﬂ uid

streams steadily from a hose, replace piston seals in the cylinder connected to that

hose.

 GRAVITY DOWN LIFTGATES: Lower the platform to the ground. Disconnect the

RETURN HOSE at the bottom of each column. Place a large container under

cylinder to catch ﬂ uid. Set control box toggle switch to UP position to raise platform.

Check if ﬂ uid is streaming from the ﬁ tting. A few drops of hydraulic ﬂ uid is okay;

however, if ﬂ uid streams steadily from the ﬁ tting, replace piston seals.
