(2) Recommended Lubricants
Always use recommended lubricants shown in Table 11.
Table 11 Recommended lubricants (Equivalent to SP type industrial extreme-pressure gear oil or JIS K2219
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.
Min. allowable viscosity
Max. allowable viscosity
15 mm

/s or more at operating oil temperature
Viscosity that ensures oil film strengh adequate for load transmission
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.

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.
