- Establish a
30.5 m (100 ft) straight speed test course. Make sure that the course provides sufficient distance for the machine to reach full speed before the machine passes the starting line. The course must also provide sufficient distance for the machine to be stopped after the finish line is passed. The course should have no slope. The course should be over a hard or firm surface. - Drive the machine to the test area.

Illustration 2 g06108976 - Operate the engine at low idle for a few minutes. Use throttle control switch (3) to operate the engine in high idle.
Note: Two things indicate when the engine is at high idle. First, "High Idle" will appear on the display. Second, the third LED next to throttle control switch (3) will be illuminated.
- Monitor the hydraulic oil temperature with Tool (A). Operate the machine until the oil temperature reaches
49 ± 6 °C (120 ± 10 °F) .Show/hide table
Illustration 3 g06113569 - Use propel mode switch (4) to shift the propel motors into the HIGH SPEED position.
Note: Two things indicate when the propel motors are in the HIGH SPEED position. First, "Propel Mode High" will appear on the display. Second, two LEDs next to propel mode switch (4) will be illuminated.
- Use increase speed switch (5) to set the propel speed to 100 percent.
Note: Two things indicate when the propel speed is set to 100 percent. First, "Speed Control % 100" will appear on the display. Second, seven LEDs next to increase speed switch (5) will be illuminated.
- Move parking brake switch (2) to the OFF position.
- Back up the machine far enough to reach full speed before the start line.
- Time the machine through the
30.5 m (100 ft) course. Acceptable travel time is 10 ± 1 sec. - Repeat the test in reverse. The forward and reverse times should be within 1 second of each other.

Illustration 4 g06113573 - Use propel mode switch (4) to shift the propel motors into the LOW SPEED position.
Note: Two things indicate when the propel motors are in the LOW SPEED position. First, "Propel Mode Low" will appear on the display. Second, one LED next to propel mode switch (4) will be illuminated.
- Repeat the test in forward and reverse. Acceptable travel time in forward is 23 ± 1 second. The forward and reverse travel times should be within 1 second of each other.
- Drive the machine to a smooth, horizontal surface.
- Move propel lever (1) to the NEUTRAL position.
- Move parking brake switch (2) to the ON position.
- Use throttle control switch (3) to operate the engine in ECO mode or in low idle.
Note: Two things indicate when the engine is in ECO mode. First, "ECO" will appear on the display. Second, the second LED next to throttle control switch (3) will be illuminated. Two things indicate when the engine is at low idle. First, "Low Idle" will appear on the display. Second, the first LED next to the throttle control switch will be illuminated.
- Move engine start switch (4) to the OFF position.
