Pump Lubrication; Pump Maintenance - Ryobi 2 900 PSI RY802925 Manuel D'utilisation

CHANGING ENGINE LUBRICANT
See Figure 24.
 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 an approved
container, then reinstall drain plug and tighten securely.
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 Specifi-
cations 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.
CHECKING SPARK PLUG
See Figure 25.
 Clean the area around the base of the spark plug before
removing to keep dirt and debris out of the engine. Re-
move 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.
MAINTENANCE

PUMP LUBRICATION

The pump on this product was lubricated with a sufficient
amount of high grade lubricant for the life of the unit under
normal operating conditions. Therefore, no further lubrica-
tion is required.

PUMP MAINTENANCE

Routinely make a visual inspection of the pump. If you no-
tice any leaking of lubricant around the pump seals, take
the pressure washer to a qualified service center for repair.
There are no user serviceable parts to the pressure washer
pump. Any attempt to service or alter the pump may dam-
age the pressure washer and void your product warranty.
STORING THE PRESSURE WASHER
See Figure 26.
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 cre-
ated 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 and the pump 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.
 Make sure the on/off switch is OFF and fuel valve is
CLOSED.
 Disconnect both the high pressure hose and the garden
hose from the pump.
 Empty the pump by pulling on the starter grip and rope
about 6 times. This should remove most of the liquid from
the pump.
NOTICE:
If the location where your pressure washer is stored will
fall below 32°F, the use of a pump protector is required
before storing to prevent freeze damage. Freeze damage
will void your warranty.
 Drain the lubricant and replace with fresh, clean lubricant
as described in Adding/Checking Engine Lubricant in
the Operation section of this manual.
