General Maintenance; Cleaning The Exhaust Port, Muf- Fler, And Spark Arrestor - Ryobi RBV254O Original Instructions Manual

GENERAL MAINTENANCE

CLEANING THE AIR FILTER
See page 33.
A wet or dirty air filter causes starting difficulty,
loss of performance, and shortens 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.
CLEANING THE EXHAUST PORT, MUF-
FLER, 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.
FUEL CAP
WARNING
A leaking fuel cap is a fire hazard and must
be replaced immediately.
The fuel cap contains a non-serviceable
filter and a check valve. A clogged fuel
filter will cause poor engine performance. If
performance improves when the fuel cap is
loosened, check valve may be faulty or filter
clogged. 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.
CLEANING THE VACUUM BAG
See page 35.
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.
REPLACING THE SPARK PLUG
See page 32.
The product's engine uses a Champion RCJ6Y
spark plug. Replace with the recommended
spark plug every 25 hours or annually.
