1.4 FUNCTION SPEEDS
Machine Orientation When Doing Speed
Tests
Lift: Boom Retracted. 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: Test to be done on a smooth level surface. Drive
Select Switch should be set to High Speed. Start approxi-
mately 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.
Lower Lift: Upper boom horizontal, telescoped in, Lower
Lift up, Record Time. Lower Lift Down, Record Time.
Lower Telescope: Lower Lift fully elevated, Upper Boom
horizontal, telescoped in. Lower Tele Out, Record Time.
Lower Tele In, 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).
