* : If the ratio of traveling time to total operating time is high, replace the gear oil earlier than
the specified time.
** : For water, use tap water (soft). Do not use well or river water. When the ambient
temperature drops below 0°C (32°F), add coolant (antifreeze). Follow the coolant
manufacturer’s instructions to determine the mixture ratio.
