1.4 FUNCTION SPEEDS

Machine Orientation When Doing Speed
Tests
Lift: Telescope Retracted. Lift Up, Record Time, Lift Down,
Record Time.
Swing: Boom at Full Elevation. Telescope Retracted.
Swing the Turntable off center and stop. Swing the oppo-
site direction and start the test when the turntable is cen-
tered up. This eliminates ramp up and down on the
controller affecting times.
Telescope: Boom at Full Elevation; Telescope Retracted;
Telescope Out, Record Time. Telescope In, Record Time.
Drive (Forward/Reverse): Test should be done on a
smooth level surface. Drive Select Switch should be set to
High Engine. Start approximately 25 ft. (7.62 m) from the
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. Drive Select Switch should be set to
Low Engine. The boom should be raised above horizon-
tal. Results should be recorded for a 50 ft. (15.24 m)
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 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.
