Set the threshold:
Note: The drive joystick adjustments are not final
adjustments. Final adjustments will need to be
made to meet drive speed specifications. Refer to
Section 2, Specifications.
7 Press down the foot switch. Move the drive
joystick off center in either direction just until a
current reading appears on the mulitmeter
display.
8 Hold the drive joystick in position and adjust
the threshold potentiometer until the
multimeter displays approximately 600 mA.
Set the high range:
9 Press down the foot switch. Move and hold the
drive joystick full stroke in either direction.
10 Hold the drive joystick in position and adjust
the hi range potentiometer until the multimeter
displays slightly higher than 1100 mA.
Set the low range:
11 Start the engine from the platform controls and
raise the primary boom approximately 3 feet /
1 m. Turn the engine off.
12 Press down the foot switch. Move and hold the
drive joystick full stroke in either direction.
13 Hold the drive joystick in position and adjust
the lo range potentiometer until the multimeter
displays approximately 700 mA.
14 Push in the red Emergency Stop button to the
off position at the platform controls.
15 Disconnect the multimeter.
16 Connect the wire that was disconnected in
step 3 to terminal "A" of the drive joystick.
Set the stowed drive speed:
Note: Select a test area that is firm, level and free
of obstructions.
17 Pull out the red Emergency Stop button out to
the on position at both the ground and
platform controls.
18 Create start and finish lines by marking two
lines on the ground 40 feet / 12.2 m apart.
19 Start the engine from the platform controls and
move the engine idle select switch to foot
switch activated high idle (rabbit and foot
switch symbol).
20 Choose a point on the machine; i.e., contact
patch of a tire, as a visual reference for use
when crossing the start and finish lines.
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 machine reference point passes over the
finish line. Refer to Section 2, Specifications.
Result: The stowed drive speed does not meet
specification. Adjust the hi range
potentiometer on the drive joystick clockwise
to increase the speed or counterclockwise to
decrease the stowed drive speed. Continue to
perform steps 20 through 22 until the stowed
drive speed meets specification.
