- Draw a 25 m (82 ft) straight line on travel test ground as a reference line.
- Start the engine.
- Place the machine controls at the following settings: Engine speed dial "10" and AEC switch OFF.
- Increase the hydraulic oil temperature to 55° ± 5°C (131° ± 9°F).
- Position the machine so that one track is parallel with the reference line. Position the machine for the travel test. Refer to Illustration 1.
- Move the machine by operating both travel levers at the same time.
- The first 5 m (16.4 ft) are for a preliminary run. Measure the travel time that is required to travel the remaining 20 m (65.6 ft). Measure the time that is required in each direction.
