Engine Lubricant:
Drain the lubricant and replace with fresh, clean lubricant.
Spark Plug:

Disconnect spark plug wire and remove the spark plug.
Pour about a teaspoon of clean, air-cooled, four-cycle
lubricant 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 neces-
sary.
 Reinstall the spark plug, but leave the spark plug wire
disconnected.
Air Filter:
Clean the air filter.
Recoil Starter Rope:
Extend the recoil starter rope to check its condition. If the
rope is frayed, have it replaced immediately by an authorized
service center.
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.
For winterizing and long-term storage:

Disconnect the water connection, if necessary.
 Disconnect the spark plug wire from the engine.
 Pull recoil rope and jump engine several times to eliminate
any water remaining in the pump.
 Coil the hoses and place in the hook-and loop strap on the
unit’s handle. Do not allow the hose to become kinked.
 Store the unit and accessories in an area that does not
reach freezing temperatures. Do not store near furnace
or other sources of heat that could dry out the pump
seals.
CAUTION:
The use of a pump protector is recommended to prevent
cold weather damage during storage over the winter
months.
PREPARING FOR USE AFTER STORAGE
 Pull the recoil starter grip three or four times to clean
lubricant from the combustion chamber.
 Remove spark plug from the cylinder. Wipe lubricant 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.
