RESERVIORS
When filling or checking the oil level, the unit should
be parked on a level surface., shut OFF, and allow
sufficient time to cool to ambient temperature. Use
caution when removing the pressurized breather.
Do not place face over opening when removing

reservior should be filled to the top of the lower
sight glass on the side of the tank. Do not overfill.
The reservoir has been overfilled when oil is visible

excess may be expelled through the pressurized
breather.

gage: The reservior should be filled to the center
of the sight glass on the side of the tank. Do not
over-fill. If the tank has too much oil, the excess
may be expelled through the pressurized breather.
