Frame Level Indicator
The Frame Level Indicator shows the lateral
(side-to-side) angle of the frame relative to level ground.
Indicator range is from 0° to 10° left or right, in
increments of one degree. When the ball is centered
(0°), the machine is laterally level. The frame tilt feature
may be used to correct machine angles up to 12.5° to
the left or right. See “Frame Tilt Control” below.
FRAME TILT CONTROL
Frame Tilt Control
The frame tilt control 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” above). The control is functional only while
the engine is running.
The control lever (1) is equipped with a safety lock to
prevent unintentional operation. Lift the lock ring (2) to
unlock the lever and allow it to be moved left or right.
Return the control lever to center position and release
lock ring to secure lever.
The lever can be moved either left or right, tilting the
frame accordingly. To level the frame, move the lever in
the direction you want the ball in the frame level
indicator to move.
