common
Second change and thereafter
5000 hrs operation or 1 year, whichever comes first.
Indoor temperature is 0-35°C
2500 hrs operation or 6 months, whichever comes first. Location where temperature cannot be kept at 0-35°C
In the case where the ambient temperature is high, there is intense change in temperature, or the air contains corrosive gas consult the oil producter.
These situations may accelerate the deterioration of the oil.
(2) Recommended Lubricants
Always use recommended lubricants shown in Table 11.

1. Use lubricants with low viscosity for operation during winter or at relatively low ambient temperature.
2. Table 12 shows allowable viscosity of the lubricant. Use the lubricant with viscosity in this range.
Table 12 Allowable viscosities
Min. allowable viscosity
15 mm

/s or more at operating oil temperature
Viscosity that ensures oil film strengh adequate for load transmission
Max. allowable viscosity
Oil-bath lubrication
4300 mm

/s max.
Viscosity that permits start-up of Buddybox
3. Make sure that the pour point of the oil is lower than the ambient temperature, at least with 5˚C difference. This is for smooth
starting.
4. When the range of operating temperature is wide, use oil with high viscosity index. The oil should meet requirements above 2
and 3.
5. Consult us when operating the unit in ambient temperature other than 0-40˚C. Parts change and preheat or cooling of lubricant
is necessary for some models.
