PLATFORM CONTROLS
6 Connect the red (+) lead from a volt meter to
the "D" terminal on the drive controller printed
circuit board. Connect the black (-) lead to
ground.
7 Turn the key switch to platform control and pull
the Emergency Stop button to the
ON
position
at both the ground and platform controls.
8 Set the brake threshold on the circuit board:
Press down the foot switch, then slowly move
the control handle off center until you hear the
pump motor turn on. Adjust the amps to 0.16
amps. Turn the threshold trimpot adjustment
screw clockwise to increase the amps or
counterclockwise to decrease the amps.
9 Set the brake max-out on the circuit board:
Press down the foot switch, then slowly move
the control handle off center until you hear the
pump motor turn off. Adjust the amps to 0.91
amps. Turn the max-out trimpot adjustment
screw clockwise to increase the amps or
counterclockwise to decrease the amps.
10 Set the drive threshold on the circuit board:
Press down the foot switch, then slowly move
the control handle off center until you see 0.28
to 0.30 amps on the amp meter. Hold the
joystick in this position then adjust the drive
threshold trimpot on the circuit board to 0.80 to
0.90V DC. Turn the threshold trimpot
adjustment screw clockwise to increase the
volts or counterclockwise to decrease the volts.
11 Set the drive high range on the circuit board:
Press down the foot switch, then slowly move
the control handle all the way to the
FORWARD
position. Adjust the high range trimpot on the
circuit board to 5.00 to 5.20V DC. Turn the high
range trimpot adjustment screw clockwise to
increase the voltage or counterclockwise to
decrease the voltage.
12 Raise the primary boom or the secondary boom
approximately 5 feet (1.5 m) to activate the
drive limit switch.
13 Set the drive lo range on the circuit board:
Press down the foot switch, then move the
control handle all the way to the
FORWARD
position. Adjust the drive lo range trimpot on
the circuit board to 1.9 to 2.0V DC. Turn the lo
range trimpot adjustment screw clockwise to
increase the voltage or counterclockwise to
decrease the voltage.
14 Lower the boom to the stowed position and
remove the lifting jacks from under the drive
chassis.
15 Raise the primary boom off the drive limit
switch.
16 Create start and finish lines by marking two
lines on the ground 40 feet (12.2 m) apart.
Choose a reference point on the machine, as a
reference for use when crossing the start and
finish lines.
17 Bring the machine to top drive speed before
reaching the start line. Begin timing when your
reference point on the machine crosses the
start line.
18 Continue at full speed and note the time when
the reference point crosses the finish line.
19 Adjust drive lo range trimpot on the circuit
board to achieve a 40 second drive speed time.
Turn the trimpot clockwise to increase the time
or counterclockwise to decrease the time.
20 Lower the primary boom to the stowed position.
21 Bring the machine to top drive speed before
reaching the start line. Begin timing when your
reference point on the machine crosses the
start line.
22 Continue at full speed and note the time when
the reference point crosses the finish line.
