Engine Oil; Transmission Oil - Wittke STARLIGHT Maintenance Manual

32 Lubrication
Following stringent maintenance schedules and performing routine oil analysis are effective methods
of obtaining information to determine the cleanliness of the hydraulic oil. Labrie Enviroquip Group
recommends that the hydraulic oil be replaced at least once a year or when contaminated. Failure to
maintain hydraulic cleanliness to recommended guidelines may result in failure of hydraulic
components and void your warranty.
Oil Recommendations
All Labrie hydraulic systems are filled at the factory with a high-quality anti-wear hydraulic fluid
meeting an ISO 32 specification. On vehicles that are used in high ambient temperatures or that
sustain high duty cycles, it may be desirable to change the fluid to an ISO 46 specification which has
higher viscosity. For vehicles working in colder climates or performing light duty cycles, an ISO 22
might be more appropriate. The International Standards Organization (ISO) assigns specification
numbers in order that a consumer receives the same product from different suppliers.
Other important points to note:
 The oil must contain anti-wear and anti-foam additives, rust and oxidation neutralizers and self-
protecting agents.
 It must also meet MIL-H-5606 or SAE IOW "MS" standards.
 The oil must be absolutely clean and free of contaminants.
Any hydraulic oil that possesses such properties may be used on a W
It is the customer's responsibility to use oil that is appropriate to the climate.
