Cleaning Air Filter; Changing Engine Oil; Spark Plug Maintenance - Ryobi RLM4614 Traduction Des Instructions Originales

■ Stop the engine and disconnect the spark plug wire.
Allow blade to come to a complete stop.
■ Turn the mower on its side (carburetor facing up).
■ Wedge a block of wood between the blade and mower
deck to prevent the blade from turning.
● Installing: See figure 9a.
● Removing: See figure 9b.
■ Using a 9/16-in. wrench or socket (not provided), loosen
the blade bolt by turning the bolt in a counterclockwise
direction as viewed from the bottom of the mower.
■ Remove the blade bolt, lock washer, flat washer, and
blade.
■ Place the new blade on the shaft. Make sure it is
installed with the curved ends pointing up toward the
mower deck and not down toward the ground.
■ Replace the flat washer, lock washer, and blade bolt
on the shaft. Finger tighten the bolt by turning in a
clockwise direction as viewed from the bottom of the
mower.
NOTE: Make certain all parts are replaced in the exact
order in which they were removed.
■ Torque the blade bolt down using a torque wrench (not
provided) to ensure the bolt is properly tightened.
■ The recommended torque for the blade bolt is 48–55
Nm (35–40 ft.lb.).
NOTE: Do not sharpen the blades, replace with new
item. Blades need to be properly balanced to avoid
damage and personal injury.

CLEANING AIR FILTER

See figure 10.
■ For proper performance and long life, keep the air filter
clean.
■ Remove the air filter cover by pushing in on the latch
with your thumb while gently pulling on the cover.
■ Remove the air filter and clean it in warm soapy water.
Rinse and let dry completely.
■ Apply a light coat of engine oil to the air filter, then
squeeze it out using an absorbent cloth or paper towel.
■ Reinstall the air filter into the air filter base.
■ Replace and secure the air filter cover.
NOTE: The fi lter should be replaced annually for best
performance.
FUEL CAP
WARNING
A leaking fuel cap is a fi re hazard and must be replaced
immediately.
The fuel cap contains a non-serviceable fi lter and a
check valve. A clogged fuel cap will cause poor engine
performance. If performance improves when the fuel cap
is loosened, check valve may be faulty or clogged. Replace
8
fuel cap if required.

CHANGING ENGINE OIL

See figure 11.
■ Ensure the fuel tank is completely empty before tipping
the unit over otherwise fuel will leak out.
■ Engine oil should be changed after every 25 hours of
use. Change the oil while the engine oil is still warm,
but not hot. This allows the oil to drain quickly and
completely.
■ Remove the oil fill cap/dipstick.
■ Tip mower onto its side and allow oil to drain from the oil
fill hole into an approved container.
■ Place mower upright and refill with oil following the
instructions in the Adding/Checking Oil section.
NOTE: Used oil should be disposed of at an approved
disposal site. See your local oil retailer for more information.

SPARK PLUG MAINTENANCE

See figure 12.
■ The spark plug must be properly gapped and free of
deposits in order to ensure proper engine operation. To
check:
■ Remove spark plug boot.
■ Clean any dirt from around base of spark plug.
■ Remove spark plug using a 13/16 in. spark plug socket
(not provided).
■ Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced.
NOTE: If replacing, use the following recommended
spark plugs or equivalent: LG F7RTC or LD F7RTC.
■ Measure plug gap. The correct gap is 0.71 mm −
0.79 mm. To widen gap, if necessary, carefully bend
the ground (top) electrode. To lessen gap, gently tap
ground electrode on a hard surface.
■ Seat spark plug in position; thread in by hand to prevent
cross-threading.
■ Tighten with wrench to compress washer. If spark plug
is new, use 1/2 turn to compress washer appropriate
amount. If reusing old spark plug, use 1/8 to 1/4 turn for
proper washer compression.
NOTE: An improperly tightened spark plug will become
very hot and could damage the engine.
■ Reinstall spark plug boot.
DRIVE GEAR MAINTENANCE
See figure 13.
To ensure smooth operation of wheels, the wheel assembly
should be cleaned before storage.
■ Remove the nut and wheel and set aside.
■ Remove dust cover, e-ring, washer, pins, and wheel
gear. Clean any dirt from these items and the end of
the drive shaft by wiping with a dry cloth. If necessary,
