Machine Orientation When Doing Function
Tests
1. LIFT:
Boom retracted, telescope retracted. Lift up, record
time. Lift down, record time.
2. SWING:
Boom at full elevation, telescope retracted.
Swing the turntable to the end stop. Swing the
opposite direction. Record time. Swing the other
direction, record time.
3. TELESCOPE:
Boom at full elevation, telescope retracted. Tele-
scope out, record time. Telescope in, record time.
4. DRIVE:
Test should be done on a smooth, level surface.
Start approximately 25 feet from starting point so
that the unit is at a maximum speed when starting
the test. Results should be recorded for a 200 foot
course. Drive forward, record time. Drive reverse,
record time.
5. DRIVE (ABOVE HORIZONTAL):
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 ft. course. Drive
forward, record time. Drive reverse, record time.
6. PLATFORM ROTATE:
Platform level and completely rotated one direction.
Rotate the opposite direction, record time. Rotate
the other direction, record time.
7. JIB:
Platform level and centered with the boom. Start
with the jib down. Jib up, record time. Jib down,
record time.
8. LOWER LIFT:
Upper boom horizontal, telescoped in. Lower lift up,
record time. Lower lift down, record time.
9. JIB SWING:
Platform level and centered with the boom. Start
with the jib horizontal. Begin with jib swing fully to
left. Swing fully to right. Record time. Swing to the
left, record time.
NOTE:
Stop watch should be started with the function, not
with the controller or switch.
All speed tests are run from the platform.
The platform speed control knob must be at full
speed. (turned clockwise completely)
The function speeds may vary due to cold thick
hydraulic oil. Tests should be run with oil tempera-
ture above 100
o
F. (38
o
C)
Some flow control functions may not work with the
speed control knob in the creep position.
