FUNCTION SPEEDS
Test Notes
1.
Stop watch should be started with the function, not
with the controller or switch.
2.
Drive test results reflect 20"x 9" air filled tires.
3.
All speed tests are run from the platform. These speeds
do not reflect ground control operation.
4.
The platform speed control knob must be at full speed
(turned clockwise completely).
5.
Function speeds may vary due to cold, thick hydraulic
oil. Tests should be run with the oil temperature above
100° F (38° C).
6.
Some flow control functions may not work with the
speed knob clicked into the creep position.

Function
Machine Position
Main Lift
Boom retracted, telescope in. Main lift up, record time. Main
lift down, record time.
Swing
Boom at full elevation, telescope retracted. Swing the turnta-
ble to the end stop. Swing the opposite direction, record time.
Swing the other direction, record time.
Telescope
Boom at full elevation, telescope retracted. Telescope out,
record time. Telescope in, record time.
Drive
Test should be done on a smooth, level surface. Start approxi-
mately 25 feet from starting point so that the unit is at a max-
imum speed when starting the test. Results should be
recorded for a 200 foot course. Drive forward, record time.
Drive reverse, record time.
Drive (Above Hori-
zontal)
Test should be done on a smooth, level surface. The platform
speed control knob should be selected out of creep speed.
This verifies that the switches are working when the boom is
above horizontal. Results should be recorded for a 50 foot
course. Drive forward, record time. Drive reverse, record time.
Platform Rotate
Platform level and completely rotated one direction. Rotate
the opposite direction, record time. Rotate the other direc-
tion, record time.
Jib
Platform level and centered with the boom. Start with jib
down. Jib up, record time. Jib down, record time.
Lower Lift
Main boom horizontal, telescoped in. Lower lift up, record
time. Lower lift down, record time.
Jib Swing
Platform level and centered with the boom. Start with jib at
horizontal. Begin with jib swung fully to left. Swing fully to
right, record time. Swing to left, record time.
