4. Using oil funnel, slowly pour contents of provided oil bottle into oil fill opening until oil reaches
upper limit "H" mark on the dipstick. Be careful not to overfill. Overfilling could cause engine
starting problems or engine damage.
5.Replace oil fill cap/dipstick and fully tighten.
6.Oil level should be checked prior to each use or at least every 8 hours of operation. Keep oil
level maintained.
The portable generator is equipped with a low oil shutdown. If the oil level drops below the
minimum required level, a sensor will activate an internal switch stopping the engine. If the
engine shuts off and the oil level is within specifications, check to see if generator is sitting at an
angle. Place portable generator on an even surface to correct this. If engine fails to start, the oil
level may not be high enough to deactivate the internal low oil level switch. Make sure the sump is
completely full of oil to the upper limit (H). Do not operate engine until oil level issue is corrected.

Operation at High Altitude
At altitudes over 5,000 feet(1524 meters), a minimum 85 octane gasoline is acceptable.
Engine power and generator output will be reduced approximately 3.5% for every 1000 feet (305 m)
of elevation above sea level. High altitude may cause hard starting, increased fuel consumption
and sparkplug fouling. To operate at high altitudes FIRMAN can provide a high altitude carburetor
main jet. The alternative main jet and installation instructions can be obtained by contacting
customer service.
NOTICE Operation using an alternative main jet at elevations lower than the recommended
minimum altitude can damage the engine. For operation at lower elevations, the standard main
jet supplied must be used. Operating the engine with the wrong main jet may increase exhaust
emissions, fuel consumption and reduce performance.
