Nozzle Maintenance; Pump Lubrication - Ryobi RY803111 Manuel D'utilisation

NOZZLE MAINTENANCE

See Figure 24.
Excessive pump pressure (a pulsing sensation felt while
squeezing the trigger) may be the result of a clogged or dirty
nozzle.
 Turn off the pressure washer and shut off the water supply.
Pull trigger to release water pressure.
 Remove the nozzle from the spray wand.
WARNING:
NEVER remove nozzles without first turning off the engine,
relieving the water pressure in the trigger handle, and lock-
ing the lock out on the trigger handle. NEVER point the
nozzle at your face or at others. The quick-connect feature
contains small springs that could eject the nozzle with some
force. Failure to follow these instructions could result in an
eye injury or other serious personal injury.
 To free any foreign materials clogging or restricting the
nozzle, blow out or remove debris with a straightened
paper clip or fine needle.
 Using a garden hose, flush debris out of nozzle by back
flushing (running the water through the nozzle backwards
or from the outside to the inside).
 Reconnect the nozzle to the spray wand.
 Turn on the water supply and start the engine.
CLEANING THE AIR FILTER
See Figure 25.
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.
 Push the tab on the air filter cover to open, then remove
the air filter cover.
 Lift the edge of the air filter carefully and pull it out.
 Brush the air filter lightly to clean.
 Reinstall the air filter.
NOTE: Make sure the filter is seated properly inside the
cover. Installing the filter incorrectly will allow dirt to enter
the engine, causing rapid engine wear.
 Reinstall the air filter cover.
MAINTENANCE
CHECKING SPARK PLUG
See Figure 26.
 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.
 Check electrode gap. The gap should be .028 in. - .032 in.
(0.7 mm - 0.8 mm). Adjust the gap, if necessary, by
carefully bending the ground electrode.
 Reinstall spark plug. Tighten securely.
CHANGING ENGINE LUBRICANT
See Figure 27.
 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.
 Tilt the pressure washer on its side as shown. 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.
 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
Specifications earlier in this manual or the accompanying
engine manual, if applicable.
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.
