FUNCTION SPEEDS
DRIVE (Below Elevation),
test should perform on a smooth,
level surface. The Drive Select Switch should be in the "Max
Speed" position. Start approximately 7.6 m (25 ft.) from start-
ing point so the unit is at a maximum speed when starting the
test.
Results should be recorded for a 61 m (200 ft.) course. Drive
forward, "High Speed", record time.
DRIVE (Above Elevation),
test should perform on a smooth,
level surface. The Drive Select Switch should be in the "Max
Speed" position, the boom should be > 10 degrees above hor-
izontal to ensure the drive is working in Max Torque mode.
Results should be recorded for a 15.2 m (50 ft.) 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,

Verify that machine will Jib Lift Up and Down. Return Knob to
fully clockwise.
JIB LIFT,
platform level and centered with the boom, jib lift
down until stop.
Jib Lift Up, record time. Jib Lift Down, record time.
Turn Platform Speed Control Knob fully counterclockwise to
enter Creep mode; Creep light on Panel must be energized.
Verify that machine will Jib Lift Up and Down. Return Knob to
fully clockwise.
PLATFORM ROTATE,
platform level, rotate platform right until
stop.
Platform Left, record time. Platform Right, record time.
Turn Platform Speed Control Knob fully counterclockwise to
enter Creep mode; Creep light on Panel must be energized.
Verify that machine will Platform Rotate Left and Right. Return
Knob to fully clockwise.
NOTE:
When the platform speed control knob turned fully coun-
terclockwise. The platform rotate may not work, this is
acceptable.
