Even with suitable carburettor jetting, engine horsepower will decrease approximately 3.5% for
each 300m (1,000 feet) increase in altitude. The effect of altitude on the horsepower will be
greater than this if no carburettor modification is made.
Operation of the generator at an altitude lower than the carburetor is jetted
for may result in reduced performance, overheating, and serious engine
damage caused by an excessively lean air/fuel mixture.
11 MAINTENANCE/CLEANING
11.1 The importance of maintenance.
Good maintenance is essential for safe, economical and trouble-free operation. It will also help
reduce air pollution.
NOTE: Before cleaning or maintenance of the generator, you must switch off the motor and
allow the equipment to cool down!
CLEANING: For cleaning the housing, please use only a lint-free cloth dampened with a
solution of soapy water (solution of washing-up liquid). During cleaning, no water should
penetrate the inside of the generator.
