NOTE: Change oil while the engine is still warm from
running, as described in the engine operator's manual.
notice
Any attempt to crank or start the engine before it has
been properly serviced with the recommended oil will
result in equipment failure.
• Refer to Maintenance and engine manual for oil fill
information.
• Damage to equipment resulting from failure to follow this
instruction will void engine and generator warranty.
4. When oil has drained, replace brass fitting on hose.
5. If all engine servicing is complete, replace 15 Amp fuse
in control panel and reset exercise timer. See Setting
Exercise Timer in Operation.
To fill your engine with oil:
Follow the oil grade recommendation and oil fill instructions
given in the engine operator's manual.
To make the task of adding oil more convenient, we
recommend use of a funnel attached to a length of tubing
long enough to reach from the Coolant Fill door to the oil fill
opening on the engine valve cover.
Engine Coolant System
With the engine cold, check the coolant level in the coolant
reservoir, seen inside the Control Panel door. Maintenance
instructions for engine coolant are found in the engine
operator's manual.
