Adjustment

7-16
(Ref. Fig. 7-9) 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
Valve" on page 7-3.
1. (Ref. Fig. 7-10) Park the machine on a firm, level surface. Place a
carpenter's level across the frame rails.
2. Loosen screws securing frame level indicator to its mounting bracket.
Start the engine and adjust frame tilt so the carpenter's level shows the
frame is level.
