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 fluids, 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.
■ You can make adjustments and repairs described in
this user manual. For other repairs, have the blower/
vacuum serviced by an authorised service dealer.
■ Check all nuts, bolts, and screws at frequent intervals
for proper tightness to ensure the product is in safe
working condition. Any part that is damaged should be
properly repaired or replaced by an authorised service
centre.
CLEANING THE AIR FILTER
See figure 15.
A wet or dirty air filter causes starting difficulty, loss of
performance, and shorten the life span of the engine. The
air filter 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 filter 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 filter is seated properly inside the
cover. Installing the filter 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, muffler, 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 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 the Ryobi website for your nearest
location or call Ryobi customer service.
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.
When refitting 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 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 16.
The product’s engine uses a Champion RCJ6Y spark plug.
Replace with a recommended every 25 hours or annually.
1. Remove the spark plug boot.
2. Loosen the spark plug by turning it counter-clockwise
