Frame Tilt Control Valve
Description
Fig. 7-2: Frame Tilt Control Valve
The frame tilt control lever is located immediately to the right of the driver’s
seat on the control panel. It is used to level the machine laterally (side-to-
side) up to 10°, left or right. The lateral angle of the machine, relative to
level ground, is shown on the frame level indicator (See “Frame Level
Indicator” on page 7-16). The control is functional only while the engine is
running.
The control lever is equipped with a safety lock to prevent unintentional
operation. Lifting the lock ring to unlock the lever allows it to be moved left
or right tilting the frame accordingly. Returning the control lever to center
position and releasing the lock ring secures the lever.
To level the frame, move the lever in the direction you want the ball in the
frame level indicator to move. Control is proportional: a small amount of
movement causes the frame to tilt slowly, while full movement of the
control causes faster frame movement.
