Frame Tilt Disabled

Under certain conditions the frame tilt system is disabled by the frame tilt
lockout valve. The lockout valve prevents or allows pilot flow to be routed to
ports A6 and B6 on the frame tilt section of the multi-spool valve. The
frame tilt lockout valve is a component of the rear oscillation lock system
and its function is explained under “Rear Oscillation Lock System” on
page 7-18.

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 12.5°, 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 7-17). 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.
