A-FRAME RAISE Bridge Build: Refer to Figure 3. 14. When illuminated this indicates the
function is active. For this function to operate correctly the A-frame pins need to be
removed. Movement of the joystick forward causes the A-frame raise cylinders to extend
raising the A-frame to the upper position. The A-frame should be raised to a point where
the A-frame pins can be re-inserted and then the A-frame is lowered onto the pins. With
the pins removed, movement of the joystick rearward causes the A-frame raise cylinders
to retract and lower the A-frame. The A-frame should be lowered until it sits on the lower
captive pins at which point the A-frame pins can be reinserted.
PUSH TO STOP - TWIST TO RESET
In this mode, forward or rearward movement of the joystick on the chest pack results in no
physical effect on the hydraulic system.
