■Hold the engine higher than the inlet end of the vacuum
tube.
■Always point the vacuum tube downhill when working
on a hillside.
■To avoid serious injury to the operator or damage to the
product, do not try to vacuum up rocks, broken glass,
bottles, or other similar objects.
■Avoid situations that could cause fire in the vacuum
bag. Do not operate the product near an open flame. Do
not vacuum up warm ash from fireplaces and barbecue
pits. Do not vacuum up discarded cigars or cigarettes
unless the cinders are completely cool.
RESIDUAL RISKS
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 or
vacuum exhaust if the bag is not fitted or damaged.
Wear adequate 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 ngers, 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 doctor about
these symptoms.
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.
MAINTENANCE
WARNING
When servicing, use only identical parts. Use of any other
parts may create a hazard or cause product damage.

9
WARNING
Always wear eye protection with side shields marked to
comply with standards, 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 product,
shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from the
spark plug. Failure to follow these instructions can result
in serious personal injury or property damage.
WARNING
Do not at any time let brake uids, petrol, petroleum-
based products, penetrating lubricants, etc., come in
contact with plastic parts. Chemicals can damage,
weaken, or destroy plastic, which can result in serious
personal injury.
■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.

working condition. Any part that is damaged should be
properly repaired or replaced by an authorised service
centre.
CLEANING THE AIR FILTER
See gure 15.
A wet or dirty air lter causes starting difculty, loss of
performance, and shorten the life span of the engine. The
air lter should be checked and cleaned after 5 hours of
operation. Inspect and clean more frequently if used in
dusty dirty conditions.
For best performance, the air lter should be replaced every
25 hours or yearly.
To clean the air filter:
1. Press the air filter cover tab to open the air filter cover.
2. Remove the cover.
3. Lift the edge of the air filter carefully and peel it out.
4. Wash the air filter with warm, soapy water.
5. Rinse and squeeze to dry.
6. To reinstall the air filter cover, insert the tabs into the
notches and lock into place.
NOTE: Make sure the lter is seated properly inside the
cover. Installing the lter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
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, mufer, and/or spark arrestor screen may
become blocked with carbon deposits. If you notice a power
loss with your petrol-powered product, you may need to
remove these deposits to restore performance. We highly
recommend that only qualied 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 re 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 the Ryobi website for your nearest
location or call Ryobi customer service.
FUEL CAP
WARNING
A leaking fuel cap is a re 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.
When retting the fuel cap ensure it is not cross-threaded,
otherwise it will leak.
FUEL FILTER
The fuel supplied to the engine is passed through a lter
to remove any contaminants from entering the engine.
Contaminants in the fuel can cause poor performance and
damage to the engine.
The fuel lter is a non-serviceable item and, if needed,
should be replaced by an authorised service centre.

■Check your equipment before operation, especially the
muffler, air intakes, and air filters.
■Use rakes and brooms to loosen debris before blowing.
WARNING
Never run the product without the blower tubes installed
or with the vacuum door not securely closed. Failure
to follow these steps could result in possible serious
injuries.
WARNING
Always wear eye protection with side shields marked to
comply with standards, along with hearing protection.
Failure to do so could result in objects being thrown into
your eyes and other possible serious injuries.
1. Start the blower. Refer to “Starting and stopping” in this
manual. Hold the blower with the upper handle in your
right hand.
WARNING
Always hold the blower away from your body with the
handle in your right hand when operating as a blower,
keeping clearance between your body and the product.
The mufer side of the blower should be away from your
body. Any contact with the housing can result in burns
and/or other serious personal injury.
WARNING
Do not place blower on top of or near loose debris or
gravel. Debris may be sucked into blower intake vent
resulting in possible damage to the product and could
result in serious personal injury.
2. To keep from scattering debris, blow around the outer
edges of a debris pile. Never blow directly into the
centre of a pile.
NOTE: Operate power equipment at reasonable hours
only; not early in the morning or late at night when people
might be disturbed. Comply with the times listed in local
ordinances.
NOTE: To reduce sound levels, limit the number of pieces
of equipment used at any one time.

do the job.
NOTE: In dusty conditions, slightly dampen surfaces
when water is available.
WARNING
Watch out for children, pets, open windows, or freshly
washed cars, and blow debris safely away.
4. Use the sweeper nozzle so the air stream can work
close to the ground.
5. After using blowers or other equipment, clean up.
Dispose of debris properly.
6. Use the sweeper nozzle for everyday blowing operation.
The nozzle allows for more area to be covered during
the blowing operation.
