IMPORTANT: Too much lubricant may cause excessive
leakage. Too little lubricant will cause gear and/or bearing
damage. Proper oil level must be maintained for
operation.
Gear cases are filled to the correct level at the factory.
Unless there is evidence of leakage, no additional
lubricant should be required. Check for evidence of
leakage every 25 hours of operation.
To ensure adequate lube level:
1. Remove filler plug. Lubricant must be at least up to
bottom of lube filler hole with unit resting on a level-
surface.
