1.7 FUNCTION SPEEDS
Test Notes
1. Stop watch should be started with the function, not
with the controller or switch.
2. Drive test results reflect standard size tires.
3. All speed tests are run from the platform. These
speeds do not reflect the ground control operation.
4. The platform speed knob control must be at full
speed (turned clockwise completely).
5. Function speeds may vary due to cold, thick hydrau-
lic oil. Test should be run with the oil temperature
above 75° F (24° C).
6. Some flow control functions may not work with the
speed knob clicked into the creep position.
Machine Orientation When Doing Speed
Tests
NOTE: All tests are to be performed on a smooth, level sur-
face.
Lift: Boom Retracted. Telescope Retracted. Lift Up,
Record Time, Lift Down, Record Time.
Swing: Boom at Full Elevation. Telescope Retracted.
Swing the Turntable to the end stop. Swing the Opposite
Direction, Record Time.
Telescope: Boom at Full Elevation; Telescope Retracted;
Telescope Out, Record Time. Telescope In, Record Time.
Drive: Test to be done on a smooth level surface. Start
approximately 25 ft. (7.62 m) from starting point so that
the unit is at maximum speed when starting the test.
Results should be recorded for a 200 ft. (60.96 m) course.
Drive Forward, record time. Drive Reverse, Record Time.
Drive (Above Horizontal): Test should be done on a
smooth level surface. The Platform Speed Knob should be
selected out of the 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 For-
ward, Record Time. Drive Reverse, Record Time.
Platform Rotate: Platform level and completely rotated
one direction. Rotate the opposite direction, Record Time.
Rotate the other direction, Record Time.
Jib: Platform level and centered with the boom. Start with
the Jib down. Jib Up, Record Time. Jib Down, Record
Time.
Lower Lift: Upper 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 Swing fully to
Left. Swing fully to Right, Record Time. Swing fully to Left,
Record Time.
