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
become blocked with carbon deposits. If you notice a power
loss with your petrol 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 product.
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:
To avoid a fire hazard, never run the blower/vacuum
without the spark arrestor in place.
VACUUM BAG
A dirty bag will reduce performance. To clean the bag, turn it
inside out and shake. Wash the bag in soapy water at least
once a year. To obtain a replacement bag, see your local
Ryobi dealer. Visit our website for your nearest location or
call Ryobi Customer Service on 1300 361 505.
FUEL CAP
WARNING:
A leaking fuel cap is a fire hazard and must be replaced
immediately.
The fuel cap contains a sealing gasket and a check valve
to ventilate built up fuel gasses. A clogged check valve will
cause poor engine performance. If performance improves
when the fuel cap is loosened, the check valve may be faulty.
Replace fuel cap if required.
The fuel supplied to the engine is passed through a filter
to remove any contaminants from entering the engine.
Contaminants in the fuel can cause poor performance and
damage to the engine.
The fuel filter is a non-serviceable item and if needed should
be replaced by a authorised service centre.
SPARK PLUG REPLACEMENT
See Figure 14.
This engine uses a Champion RCJ-6Y or NGK BPMR7A
spark plug with .025 in. electrode gap. Use an exact
replacement and replace annually.
Follow these steps to replace the spark plug:
1. Remove the spark plug boot.
2. Loosen the spark plug by turning it counterclockwise
with a 16 mm socket.
3. Remove the spark plug.
4. Hand thread the new spark plug, turning it clockwise.
NOTE:
A small amount of anti seize compound on the thread
of the new plug will ensure easy removal on the next service.
5. Tighten with a socket. Do not overtighten.
WARNING:
Be careful not to cross-thread the spark plug. Cross-threading
will seriously damage the product.
