1-4 – JLG Lift – 3120840
Platform Rotate: Platform level and completely rotated
one direction. Rotate the opposite direction, Record Time.
Rotate the other direction, Record Time.
Articulating Jib: Platform level and centered with the
boom. Start with the Jib down. Jib Up, Record Time. Jib
Down, Record Time.
Test Notes
1. Stop watch should be started with the function, not
with the controller or switch.
2. All speed tests are run from the platform. These
speeds do not reflect the ground control operation.
3. The platform speed knob control must be at full
speed (turned clockwise completely).
4. Function speeds may vary due to cold, thick hydrau-
lic oil. Test should be run with the oil temperature
above 100° F (38° C).
5. Some flow control functions may not work with the
speed knob clicked into the creep position.
