These lubrication instructions are for unit level maintenance personnel. Lube intervals (on-condition or
hard time) are based on normal operation. Lube more during constant use, and less during inactive
periods. Use correct grade of lubricant for seasonal temperature expected.
Always wipe clean oil filler components before starting your lube service. Use correct type
or grade of oil. Overfilling will cause spillage and harm engine components.
