RESIDUAL RISK
Even when the product is used as prescribed, it is still
impossible to completely eliminate certain residual risk
factors. The following hazards may arise in use and the
operator should pay special attention to avoid the following:
Injury caused by vibration.
–
Always use the right tool for the job. Use designated
handles and restrict working time and exposure.
Hearing damage caused by exposure to noise.
–
Wear ear protection and limit exposure.
Injury from flying objects from the blow tube airflow
–
Wear eye protection at all times.
RISK REDUCTION
It has been reported that vibrations from handheld tools
may contribute to a condition called Raynaud’s Syndrome
in certain individuals. Symptoms may include tingling,
numbness, and blanching of the fingers, usually apparent
upon exposure to cold. Hereditary factors, exposure to
cold and dampness, diet, smoking and work practices
are all thought to contribute to the development of these
symptoms. There are measures that can be taken by the
operator to possibly reduce the effects of vibration:
Keep your body warm in cold weather. When operating
the product wear gloves to keep the hands and wrists
warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.
After each period of operation, exercise to increase blood
circulation.
Take frequent work breaks. Limit the amount of exposure
per day.
If you experience any of the symptoms of this condition,
immediately discontinue use and see your physician.
WARNING
Injuries may be caused, or aggravated, by prolonged use of
a tool. When using any tool for prolonged periods, ensure
you take regular breaks.

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.
NOTE:
Vacuum components are optional and sold separately.
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 allow air in. 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.
FUEL FILTER
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 an 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.
