CLEANING THE EXHAUST PORT
NOTICE:
The spark arrestor on this product has not been evalu-
ated by the USDA Forest Service and cannot be used on
U.S. forest lands. In addition, product users must comply
with Federal, State, and local fire prevention regulations.
Check with appropriate authorities. Contact customer
service or a qualified service center to purchase a re-
placement spark arrestor.
NOTE: Depending on the type of fuel used, the type and
amount of lubricant used, and/or your operating conditions, the
exhaust port, muffler, and/or spark arrestor screen may be-
come blocked with carbon deposits. If you notice a power
loss with your gas powered tool, you may need to remove
these deposits to restore performance. We highly recommend
that only qualified service technicians perform this service.
The spark arrestor must be cleaned or replaced every 50
hours or yearly to ensure proper performance of your prod-
uct. Spark arrestors may be in different locations depending
on the model purchased. Please contact your nearest service
dealer for the location of the spark arrestor for your model.
WARNING:
Never run the blower without a muffler equipped with a
spark arrestor in place. Failure to do so could result in a
fire that could cause serious personal injury.
MAINTENANCE
FUEL CAP, TANK, AND LINES
WARNING:
Check for fuel leaks. A leaking fuel cap, tank, or line is a
fire hazard and must be replaced immediately. If you find
any leaks, correct the problem before using the product.
Failure to do so could result in a fire that could cause
serious personal injury.
The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel filter will cause poor engine per-
formance. If performance improves when the fuel cap is
loosened, the check valve may be faulty or filter clogged.
Replace the fuel cap if required.
STORING THE PRODUCT
 Clean all foreign material from the product. Store it in a
well-ventilated place that is inaccessible to children. Keep
away from corrosive agents such as garden chemicals
and de-icing salts.
 Abide by all Federal and local regulations for the safe
storage and handling of gasoline.
When storing 1 month or longer:
 Drain all fuel from tank into a container approved for
gasoline. Run engine until it stops.
HIGH ALTITUDE ENGINE OPERATION
Your engine is configured for operation below 2000 feet
altitude at the factory. Your engine must be reconfigured for
operation above 2000 feet altitude. Operating the engine
with the wrong engine configuration at a given altitude may
increase its emissions, decrease fuel efficiency, degrade
performance, and cause irreversible damage. Engines
configured for high altitude operation cannot be operated
in standard altitude conditions. A qualified service center
should ensure that your engine is properly configured for
your location.
