100HX+10 (110HXER).
1. Length Indicator Adjustment.
a. Fully retract the boom and place it in the 0 (+3/-
0) degrees horizontal position.
b. With the engine running, check test point 10
(TP10).
c. Set TP1 on the load radius circuit card to 1.8
Volts by adjusting P1.
d. Loosen the Allen screws which anchor the tim-
ing belt pulley (1st generation) or timing gear
(2nd generation) to the shaft of the 5K pot. On
3rd generation sensor boxes, loosen the three
screws holding the pot in place. This enables
the pot/pot shaft to move freely.
e. Turn the ignition switch on. Adjust the 5K pot/pot
shaft until the proper voltage appears at TP2 on
the load radius circuit card and also at the green
wire on the 5K pot. (See Table 2-5 for proper
voltage.)
f. Tighten the Allen screws on the timing belt pul-
ley/timing gear or tighten the three screws, as
applicable.

2. Boom Angle Sensor Adjustment.
a. With the boom completely retracted and in the 0
(+3/-0) degrees horizontal position, measure
the voltage at TP3 on the load radius circuit card
and at the yellow wire on the boom angle sen-
sor.
b. Adjust the spring-loaded screw on the boom
angle sensor mounting plate (1st generation) or
the trim pot on the boom angle sensor (2nd gen-
eration) until the voltage at TP3 on the load
radius circuit card and the yellow wire on the
boom angle sensor reaches the proper voltage.
For the 3rd generation sensor boxes, loosen the
three screws securing the sensor to the box and
rotate the sensor until the proper voltage read-
ing is obtained, then retighten the screws. (See
Table 2-5 for proper voltage.)
