WARNING:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1, along with hearing protection.
Failure to do so could result in objects being thrown into
your eyes and other possible serious injuries.
WARNING:
Before inspecting, cleaning, or servicing the machine,
shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from spark
plug. Failure to follow these instructions can result in
serious personal injury or property damage.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury.
You can often make adjustments and repairs described here.
For other repairs, have the blower/vacuum serviced by an
authorized service center.

MAINTENANCE
CLEANING THE EXHAUST PORT, MUFFLER
AND 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 recom-
mend 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 the spark arrestor in place.
Failure to do so could result in a fire that could cause
serious personal injury.
FUEL CAP
WARNING:
Check for fuel leaks. A leaking fuel cap 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
performance. If performance improves when the fuel cap
is loosened, check valve may be faulty or filter clogged.
Replace fuel cap if required.
SPARK PLUG REPLACEMENT
This engine uses a Champion RY4C spark plug with .025 in.
electrode gap. Use an exact replacement and replace
annually.
