11 - Test the Drive Speed - Stowed Position
Tools will be required to perform this procedure.
This procedure is to be performed every 3 months or every 250 hours, whichever comes first.
Proper drive functions are 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.
Perform this procedure with the machine on a firm, level surface that is free of obstructions.
Create start and finish lines by marking two lines on the ground 40 ft / 12.2 m apart.
Turn the key switch to platform control and pull out the red Emergency Stop button to the ON
position at both the ground and platform controls.
Lower the platform to the stowed position.
Press the drive function select button.
Choose a point on the machine; i.e., contact patch of a tire, as a visual reference for use when
crossing the start and finish lines.
Bring the machine to top drive speed before reaching the start line. Begin timing when your
reference point on the machine crosses the start line.
Continue at full speed and note the time when your reference point on the machine passes over
the finish line. Refer to chart on next page.
