Note: The maximum drift represents the travel deviation (distance) from the reference line.
Note: The engine speed and/or the machine configuration that is used during this test can affect the results of this test. Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for the engine speed that was used for this test. Refer to Testing and Adjusting, "Operational Checks" for the machine configurations that were used for this test.
Note: The relief valve pressure settings must be set to the relief valve pressure specification before performing this operational check. Refer to Testing and Adjusting, "Specifications".

- Travel distance must be at least
20 m (65.6 ft) long. Travel test ground must be hard and as level as possible. - Draw a
30 m (98.4 ft) straight line on travel test ground as a reference line.

(A) Preliminary run (B) Travel distance |
- Start the engine.
- Place the engine speed dial in the HIGH IDLE position.
- Increase the hydraulic oil temperature to
55° ± 5°C (131° ± 9°F) . - The bucket should be empty.
- Position the machine so that one track is parallel with the reference line. Position the machine for the travel test. Refer to Illustration 1.
- Place the travel speed control switch on the HIGH position.
- Move the machine by operating both travel levers at the same time.
- The first
10 m (32.8 ft) are for a preliminary run. Measure the travel time that is required to travel the remaining20 m (65.6 ft) . Measure the time that is required in each direction. - Measure the travel deviation from the reference line.
- Place the travel speed control switch on the LOW position and repeat Steps 7 through 9.
