HYDRAULIC OIL
The following lists some features to look for in an oil. The hydraulic oil for the machine should feature:
- Rust resistant additives to prevent rust formation from moisture condensation.
- Anti-foaming agents to break up air bubbles and prevent "foaming" that may cause sluggish and erratic operation.
- High stability to resist oxidation and prevent varnish formation and deposits that foul systems.
- Anti-wear properties to prevent scuffing and exccesive wear at high speeds and high pressures.
- Good viscosity index for easy flow at low temperatures without thinning out at high temp's after hours of use.
ENGINE OIL
Refer to the specifications in the engine manufacturer's manuals that are supplied with every new machine.
FUEL SPECIFICATIONS
Use grade no. 2-D fuel above 40 degrees F.
Use grade no. 1-D fuel below 40 degrees F.
Use grade no. 1-D fuel for all air temperatures at altitudes.
NOTE: Change the engine oil at one half the normal interval if fuel sulfur content exceeds 0.5%. Use fuel with
less than 1.0% sulfur. Use fuel with less than 0.5% sulfur if possible. Sediment and water should not
exceed 0.10% for maximum filter life.
The Cetane number should be 40 minimum. A fuel with a higher Cetane number may be required if operating the
machine where air temperatures are normally low or where altitudes are high. In cold weather operation, the cloud
point should be 10 degrees F. below lowest normal air temperatures.
