*: If the traveling time accounts for a high ratio of the total operating time, replace the gear oil
ahead of the specified periods.
**: Use running water (soft water). Do not use well water or river water. If the outside temperature is
<0℃, add coolant (antifreeze). Determine the mixture ratio as per the coolant manufacturer's
instructions.
***: The replacement period of hydraulic oil depends on the type of hydraulic oil in use. The new
machine is filled with Ken stone genuine hydraulic oil 46 at the time of delivery and the
hydraulic oil replacement periods described in this manual are based on the use of Ken stone
genuine hydraulic oil 46. When common anti-wear hydraulic oil is used, replace the hydraulic oil
once every 2,000h.
