the dipstick.
• Add oil only if the oil level is below the ADD mark
on the bottom of the cross-hatch pattern on the
dipstick.
• DO NOT OVERFILL the crankcase.
• Verify the fuel level.
• Verify the remote switch is also off and tagged if
the unit is connected to a remote start or transfer
switch.
NOTE: If the engine was run out of fuel, or the fuel tank
was drained, it may be necessary to purge the fuel lines.
See the engine operator’s manual supplied with the unit
