BOOM ANGLE INDICATOR
Boom Angle Indicator
The boom angle indicator shows the angle of the boom
relative to level ground. Use this indicator with the boom
extension indicator, transfer carriage extension
indicator, and vehicle load chart to determine correct
boom lifting capacities. See “Sample Load Chart” on
page 40.
BOOM EXTENSION INDICATOR
Boom Extension Indicator (typical)
The boom extension indicator shows the amount of
boom extension. The letters on the boom correspond to
the lettered zones on the load chart. Use this indicator
with the boom angle indicator, transfer carriage
extension indicator (if equipped), and vehicle load chart
to determine correct boom lifting capacities. See
“Sample Load Chart” on page 40.
TRANSFER CARRIAGE EXTENSION
INDICATOR
Transfer Carriage Extension Indicator
The transfer carriage extension indicator shows the
distance of the carriage from the fully retracted position.
Use this indicator with the boom angle indicator, boom
extension indicator, and vehicle load chart to determine
correct boom lifting capacities. See “Sample Load
Chart” on page 40.
FRAME LEVEL INDICATOR
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 vehicle is laterally level. The frame tilt feature
may be used to correct vehicle angles up to 10° to the
left or right. See “Frame Tilt Control” on page 24.
