Place the travel speed control switch in HIGH position.
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.
