Pump Maintenance - Ryobi RY80544 Manuel D'utilisation

CLEANING/REPLACING THE AIR FILTER
See Figure 20.
A dirty air filter will cause starting difficulty, loss of
performance, and shorten the life span of the engine. Check
the air filter monthly. For best performance, replace the air
filter at least once a year.
The filter cover pivots up and lifts off.
 Using a damp cloth, wipe the air filter cover and
inner surface. Take care not to allow dust to enter the
carburetor.
 Remove the air filter.
 Rinse filter with clean water.
 Gently squeeze filter until excess water is removed.
 Apply a light coat of engine lubricant to the filter, then
squeeze it out.
 Reinstall the foam filter.
NOTE: Make sure the filter is seated properly inside the
compartment. Installing the filter incorrectly will allow dirt
to enter the engine, causing rapid engine wear.
 Reinstall the filter cover.
CHANGING ENGINE LUBRICANT
See Figure 21.
 Shut off the engine.
 Clean the area around the oil cap/dipstick, then remove
the oil cap/dipstick.
NOTE: Remove the dipstick to allow lubricant to drain
easier and more quickly.
 Disconnect the spark plug wire from the engine.
 To drain the lubricant, remove the drain plug from the
bottom of the engine. Drain lubricant into approved
container.
NOTE: Drain the lubricant while the engine is still warm
but not hot. Warm lubricant will drain quickly and more
completely.
WARNING:
Do not change engine lubricant while it is hot. Accidental
contact with hot engine lubricant could result in serious
burns.
 Fill with lubricant following the instructions in Adding/
Checking Engine Lubricant earlier in this manual.
For amount of lubricant needed to refill, see Product
Specifications earlier in this manual or the accompanying
engine manual, if applicable.
 Before using the pressure washer, check to ensure that
no lubricant is leaking from the engine.
NOTE: Consult hazardous waste management guidelines in
your area for the proper way to dispose of used lubricant.
MAINTENANCE
CHECKING SPARK PLUG
See Figure 22.
 Clean the area around the base of the spark plug before
removing to keep dirt and debris out of the engine.
Remove spark plug.
 Clean off carbon deposits on the spark plug electrode
using a plug cleaner or wire brush. Replace the plug if
worn or reuse is questionable. For replacement spark
plug, see Product Specifications earlier in this manual
or the accompanying engine manual, if applicable.
 Check electrode gap. The gap should be 0.7 - 0.8 mm.
Adjust the gap, if necessary, by carefully bending the
ground electrode.
 Check the condition of the spark plug gasket.
 Reinstall spark plug. Start the spark plug in its threads
by hand and finger-tighten.
 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.

PUMP MAINTENANCE

Routinely make a visual inspection of the pump. If you notice
any leaking of lubricant around the pump seals, take the
pressure washer to an authorized service center for repair.
There are no user serviceable parts to the pressure washer
pump. Any attempt to service or alter the pump may damage
the pressure washer and void your product warranty.
STORING THE PRESSURE WASHER
See Figure 23.
NOTE: Regular use of fuel stabilizer and pump protector
will give you better performance of the unit and increase
the life of the pump.
WARNING:
While storing, keep at least 3 feet of clearance on all sides
of this product, including overhead. Allow a minimum
of 30 minutes of "cool down" time before storage. Heat
created by muffler and exhaust gases could be hot
enough to ignite combustible objects.
Store in a dry, covered area where the weather can't damage it.
It is important to store this product in a frost-free area. Always
empty water from all hoses, the pump, and the soap tank
before storing.
 Drain the fuel tank completely by running the pressure
washer until the gas runs out. Stored gas can go stale in
30 days.
NOTE: Make sure the water supply is connected and
turned on when allowing the pressure washer engine to
run.
