Ryobi RY802900 Operator's Manual page 19

 If the filter element is dirty, clean with warm, soapy water.
Rinse and let dry.
 Apply a light coat of engine lubricant to the element, then
squeeze it out.
 Replace the element in the air filter unit.
 Replace the air filter cover and latch to secure.
NOTE: Do not run the pressure washer without the air filter.
Rapid engine wear will result.
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 .028 in.-.032 in.
(0.7- 0.8 mm). Adjust the gap, if necessary, by carefully
bending the ground electrode.
 Reinstall spark plug. Tighten securely.
CHANGING ENGINE LUBRICANT
See Figure 23.
 Shut off the engine.
 Clean the area around the oil fill cap/dipstick, then remove
the oil fill cap/dipstick.
NOTE: Remove the dipstick to allow lubricant to drain
easier and more quickly.
 Tilt the pressure washer on its side as shown. Drain lu-
bricant 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.
 After the crankcase is completely drained, return the
pressure washer to an upright position.
 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.
MAINTENANCE
NOTE: Consult hazardous waste management guidelines in
your area for the proper way to dispose of used lubricant.
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
notice 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 damage
the pressure washer and void your product warranty.
STORING THE PRESSURE WASHER
See Figure 24.
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 fuel valve is in the CLOSED position.
 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.
