In general, capacitive and inductive load, especially, motor-driven devices have a big
starting current when starting.
3. HIGH ALTITUDE OPERATION
At high altitude, the standard carburetor air-fuel mixture will be excessively rich. Output
power will decrease, and fuel consumption will increase. Engine performance can be
improved by installing a smaller diameter main fuel jet in the carburetor and readjusting the
pilot screw. If you always operate the engine at altitudes above sea level 1000 meters,
have our company authorized dealer perform this carburetor modification. If not, lower load
power in operating generator.
Even equipped with suitable carburetor, engine horsepower will decrease approximately
3.5% for each 300 meter increase in altitude. The effect of altitude on horsepower will be
lowered greater than this if no carburetor modification is made.
If a carburetor for high altitude is equipped with engine suitable to a lower altitude,
the lean air fuel mixture will cause the engine output power lowering, over-heat and
seriously damage.
PRE-OPERATION CHEK
1. ENGINE OIL
Engine oil is a major factor affecting engine performance and service life. Non-
detergent and 2-stroke engine oils will damage the engine and are not
recommended. Check the oil level before each use with the generator on a level
surface with the engine stopped.
Recommended oil
4-stroke gasoline oil
API service Classification's SF
or SAE10W-30 of equivalent SG class.
Method of check oil level:
Remove the oil filler cap and wipe the dipstick clean.
Check the oil level by inserting the dipstick into the filler neck without screwing it in.
If the level is low, add the recommended oil to the upper mark on the dipstick.
After adding, don’t forget
to reinsert and screw down the oil dipstick.
