Cleaning The Exhaust Port, Muffler, And Spark Arrestor - Ryobi RBV26B User Manual

CLEARING A BLOCKAGE
To reduce the risk of injury associated with contacting
rotating parts, always stop the engine, and make sure
all moving parts have come to a complete stop.
Remove the blower tubes to inspect for blockage.
Clear the tubes if required.
Remove the debris collector bag. Check that the bag
adaptor is free from obstruction.
Inspect the opening to the fan enclosure and the tube
to the debris bag for evidence of a blockage. Keep
fingers away from the fan or mulching blades at all
times.
Do not attempt to remove the fan or mulching blade. If
it is necessary to remove the fan or mulching blades,
bring the product to an authorised service centre.
Reinstall the tubes and the debris collector bag before
starting the product.
CLEANING THE AIR FILTER
See  gure 12 - 13.
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
yearly.
Remove the air filter cover by turning the dial counter
clockwise while gently pulling out the cover.
Rinse the filter with clean water.
Gently squeeze filter until excess water is removed.
Replace the filter.
Place the air filter cover back on the product. Turn dial
clockwise until the cover is secured.
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, 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
English (Original instructions)
the model purchased. Please contact your nearest service
dealer for the location of the spark arrestor for your model.
To avoid a  re hazard, never run the blower without the
spark arrestor in place.
FUEL CAP
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.
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.
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.
SPARK PLUG REPLACEMENT
This engine uses a Ryobi AC00160, Champion RCJ-6Y,
or NGK BPMR7A spark plug with a 0,63 mm (0,025 in.)
electrode gap. Use an exact replacement and replace
annually.

WARNING
WARNING
Remove the spark plug boot.
Loosen the spark plug by turning it counter-clockwise
with a socket.
Remove the spark plug.
Inspect the new spark plug. The spark plug must be
properly gapped and free of deposits in order to ensure
proper engine operation. The correct gap is 0,63 mm
(0,025 in.). To widen gap, if necessary, carefully bend
the ground (top) electrode. To lessen gap, gently tap
ground electrode on a hard surface.
