Maintenance - Ryobi RY09465 Operator's Manual

WARNING:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1, 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 machine,
shut off engine, wait for all moving parts to stop, and
disconnect spark plug wire and move it away from spark
plug. Failure to follow these instructions can result in
serious personal injury or property damage.
GENERAL MAINTENANCE
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.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricants, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury.
You can often make adjustments and repairs described here.
For other repairs, have the blower serviced by an authorized
service center.
CLEANING THE AIR FILTER
See Figure 10 - 11.
For proper performance and long life, keep air filter clean.
 Remove the air filter cover by turning the dial counter
clockwise while gently pulling on the cover.
 Rinse filter with clean water.
 Gently squeeze filter until excess water is removed.
Replace filter.
 Place the air filter cover back on the unit. Turn dial clock-
wise until cover is secure.

MAINTENANCE

FUEL CAP , TANK, AND LINES
Check for fuel leaks. A leaking fuel cap, tank, or lines
are a fire hazard and must be replaced immediately. If
you find any leaks, correct the problem before using the
product. Failure to do so could result in a fire that could
cause serious personal injury.
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.
SPARK PLUG REPLACEMENT
This engine uses a Champion RY4C or equivalent spark plug
with .025 in. electrode gap. Use an exact replacement and
replace annually.
Be careful not to cross-thread the spark plug. Cross-
threading will seriously damage the product.
CHANGING ENGINE LUBRICANT
See Figures 12 -13.
Do not change engine lubricant while it is hot. Accidental
contact with hot engine lubricant could result in serious
burns.
For best performance, engine lubricant should be changed
after every 25 hours of operation.
To change the engine lubricant:
 Stop the engine. Allow the engine to cool completely
before proceeding.
 Remove the screw from the top engine cover and set
aside.
 Remove the screws from engine cover. Remove the cover
and set aside.
 Disconnect the spark plug wire.
 Remove the oil fill cap/dipstick.
 Tip blower on its side and allow lubricant to drain from
the oil fill hole into an approved container.
NOTE: Drain the lubricant while the engine is still warm
but not hot. Warm lubricant will drain quickly and more
completely.
