1. Create start and finish lines by marking two lines on the ground 40 ft /12.2 m apart.
2. Turn the key switch to platform control and turn the red Emergency Stop button clock-
wise to the on position at both the ground and platform controls.
3. Press the lift function select button.
4. Press and hold the function enable switch on the joystick.
5. Raise the platform approximately 10 ft /3 m from the ground.
6. Press the drive function select button.
7. 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.
8. 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.
9. Continue at full speed and note the time when your reference point on the machine
passes over the finish line. The time should be 54-62 seconds.

Replacement or testing of the hydraulic oil is essential for good machine performance
and service life. Dirty oil may cause the machine to perform poorly and continued use
may cause component damage. Extremely dirty conditions may require oil changes to
be performed more often.
Before replacing the hydraulic oil, the oil may be tested by an oil distributor for specific
levels of contamination to verify that changing the oil is necessary.
Hydraulic oil should be tested yearly and replaced if it fails. If the hydraulic oil is not
replaced at the Annual Inspection, test the oil quarterly. Replace the oil when it fails the
test.

A free-breathing hydraulic tank cap is essential for good machine performance and
service life. A dirty or clogged cap may cause the machine to perform poorly. Extremely
dirty conditions may require that the cap be inspected more often.
1. Remove the breather cap from the hydraulic tank.
2. Check for proper venting.
• Result: Air passes through the breather cap.
• Result: If air does not pass through the cap, clean or replace the cap. Proceed to step 3.
NOTE: When checking for positive tank cap venting, air should pass freely through the cap.
3. Using a mild solvent, carefully wash the cap venting system. Dry using low pressure
compressed air. Repeat step 2.
4. Install the breather cap onto the hydraulic tank.
