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 Turret 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. The Driving Mode choosing Switch should be
selected Run Mode and Drive Speed Controller pulled to limit. 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. Driving Mode
choosing Switch should be selected Creep Mode and Drive Speed Controller pulled to limit. 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.
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.
Test Notes
1. Stop watch should be started with the function, not with the controller or switch.
2. Drive test results reflect 315/55 D20 tires.
3. All speed tests are run from the platform. These speeds do not reflect the ground control
operation.
4. The platform speed Toggle Switch control must be at full speed
5. Function speeds may vary due to cold, thick hydraulic oil. Test should be run with the oil
temperature above 100° F (38° C).
6. Some flow control functions may not work with the speed knob clicked into the creep position.
