Table 1-8. Machine Orientation When Performing Speed Test
Drive;
(Max Speed)
Test should be done on a smooth, level surface. Start approximately 7.6m (25 ft) from starting point so the unit is at a maximum speed when
starting the test.
Results should be recorded for a 61m (200ft) course.
Drive forward, "High Speed", record time
Drive Reverse, "High Speed", record time
Drive;
(Max Torque)
(Above Horizontal)
Test should be done on a smooth, level surface. The Drive Select Switch should be in the "Max Speed" position, the boom should be > 10° above
horizontal to ensure the drive is operating in Max Torque mode.
Results should be recorded for a 15.25m (50ft) course.
Drive forward, record time
Drive Reverse, record time
Turn Platform Speed Control Knob fully counterclockwise to enter Creep mode; Creep light on Panel must be energized. Verify that machine will
drive forward and reverse. Return Knob to fully clockwise.
Swing Boom at full elevation, Telescope retracted. Swing the turntable left or right to the end stop.
Swing in the opposite direction until the turn table stops, record time.
Swing in the other direction until the turn table stops, record time.
Turn Platform Speed Control Knob fully counterclockwise to enter Creep mode; Creep light on Panel must be energized. Verify that machine will
swing left and right. Return Knob to fully clockwise.
Main Lift Main Lift retracted, Telescope Retracted.
Main Lift up to full height, record time.
Main Lift Down to stowed position, record time.
Turn Platform Speed Control Knob fully counterclockwise to enter Creep mode; Creep light on Panel must be energized. Verify that machine will
lift up and down. Return Knob to fully clockwise.
Telescope Main Lift completely extended, Telescope Retracted.
Telescope out (full height), record time.
Telescope in (stowed position), record time.
Turn Platform Speed Control Knob fully counterclockwise to enter Creep mode; Creep light on Panel must be energized. Verify that machine will
telescope in and out. Return Knob to fully clockwise.
Platform
Rotate
Main Lift retracted, Telescope Retracted. Rotate the platform left or right until the platform stops
Rotate the platform in the opposite direction until the platform stops, record time.
Rotate the platform in the other direction until the platform stops, record time.
Turn Platform Speed Control Knob fully counterclockwise to enter Creep mode; Creep light on Panel must be energized. Verify that machine plat-
form will rotate left and right.
Note: When the platform speed control knob is turned fully counterclockwise. The platform rotate may not work, this is acceptable. Return Knob
to fully clockwise.
