MAINTENANCE
Discharge Fuel:
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.
Engine Oil:
Drain the oil and replace with fresh, clean oil.
Spark Plug:
 Disconnect spark plug wire and remove the spark plug.
Pour about a teaspoon of clean, air-cooled, four-cycle
oil through the spark plug hole into the combustion
chamber.
 Leaving the spark plug out, pull the starter cord two or
three times to coat the inside of the cylinder wall.
 Inspect the spark plug and clean or replace, as necessary.
 Reinstall the spark plug, but leave the spark plug wire
disconnected.
Air Filter:
Clean the air filter.
Fuel Tank Inlet Screen:
For best performance, clean the tank's inlet screen yearly or
after every 100 hours of use. If the screen is damaged, call
customer service to order a replacement screen.
WARNING:
This product and the engine exhaust from this product may contain chemicals, including lead, known to the State
of California to cause cancer, birth defects, or other reproductive harm. Wash hands after handling.
 Remove fuel tank inlet screen.
 Flush with warm soapy water.
 Rinse and re-install screen in tank filler neck.
Fuel Tank Outlet Filter:
Dirty tank fuel filters will cause starting difficulty, loss of per-
formance, and shorten the life span of the engine. Contact an
authorized service dealer to check and clean the tank outlet
filter yearly. For best performance, have the filter replaced
after 200 hours of use.
Hoses and Pump:
Flush the injection hose with clean water for 1-2 minutes.
Remove all hoses. Empty the pump by pulling on the recoil
starter about 6 times. This should remove most of the liquid
from the pump.
PREPARING FOR USE AFTER STORAGE
 Pull the recoil starter grip three or four times to clean oil
from the combustion chamber.
 Remove spark plug from the cylinder. Wipe oil from the
spark plug and return it to the cylinder.
 Reconnect the spark plug wire.
 Refuel the machine as described earlier in the operator's
manual.
