( 1 ) These oils are special oils with synthetic base stocks that do not contain polymer viscosity index improvers. The high viscosity index of the synthetic oils provides natural multiviscosity properties.
( 2 ) For BIO HYDO oil, continuous heavy-duty operation is limited to 32°C (90°F) outside ambient temperature. Operation at outside ambient temperatures above 32°C (90°F) should be limited to light duty cycles and short periods of time. Do not use BIO HYDO oil in hydraulic systems with clutches or brakes. Do not use BIO HYDO oil in hydraulic systems with jacket water coolant systems such as large track-type tractors or off-highway trucks.
