• Turn the fuel valve to the “OFF” position.
• Remove the fuel line from both sides of the filter by squeezing the ends of the retaining clip with pliers.
• Slide the fuel line off.
• Replace with new fuel filter.
• Reinstall fuel lines to new fuel filter.
• Turn the fuel valve to the “ON” position.
Replacing Fuel Filter (See Fig 25 If Applicable)
Occasionally the fuel filter may become clogged and need replacing. To purchase a replacement fuel filter contact PULSAR
customer service or your local small Engine repair shop.
Fuel tank must be empty before replacing fuel filter. Run unit until tank is empty, if needed,
or inspect filter prior to fill-up.
CAUTION!
Draining Fuel Tank and Carburetor
To help prevent gum deposits in the fuel system, drain the fuel from the tank and carburetor before storing the unit for long
periods of time. This will help prevent starting problems in the future. If the unit is stored with fuel and the fuel becomes
stale or turns gummy or to varnish the warranty does not cover this repair or service.
Fig 25Fig 24
Draining the fuel tank
• Turn the engine OFF.
• Turn the fuel valve to the OFF position.
•
When the fuel has drained from the tank, close the fuel valve and reinstall fuel line securely on petcock.
• Remove the fuel line that leads to the carburetor from the petcock by squeezing the ends of the hose clamps and
sliding the fuel line off.
• If needed, install a fuel hose that will extend to a suitable fuel container large enough to catch the fuel being drained
from the tank.
•
Turn the fuel valve to the ON position.
High Altitude OperationHi
At high altitude, the standard carburetor air/fuel mixture will be too rich. Performance will decrease, and fuel consumption will
increase. A very rich mixture will also foul the spark plug and cause hard starting. Operation at an altitude that differs from
that at which this engine was certified, for extended periods of time, may increase emissions. High altitude performance can
be improved by specific
modifications to the carburetor. If you always operate your generator at altitudes above 5,000 feet
(1,500 meters), have your dealer perform this carburetor modification. This engine, when operated at high altitude with the
carburetor modifications for high altitude use, will meet each emission standard throughout its useful life. Even with
carburetor modification, engine horsepower will decrease about 3.5% for each 1,000-foot (300-meter) increase in altitude.
The effect of altitude on horsepower will be greater than this if no carburetor modification is made.
