Proper drive function movement is essential to
safe machine operation. The drive function should
respond quickly and smoothly to operator control.
Drive performance should also be free of
hesitation, jerking and unusual noise over the
entire proportionally controlled speed range.
Note: Select a test area that is firm, level and free
of obstructions.

lines on the ground 40 feet / 12.2 m apart.
2 Start the engine from the platform controls.
3 Move the engine idle control switch to
foot switch activated high idle (rabbit and foot
switch symbol), then lower the boom into the
stowed position.

patch of a tire, as a visual reference for use
when crossing the start and finish lines.

reaching the start line. Begin timing when your
reference point on the machine crosses the
