Nozzle Maintenance; Pump Lubrication - Ryobi RY803111 Manual Del Operador

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.
