NOTE:
In some areas, local law requires using a resistor spark plug to
suppress ignition signals. If this engine was originally equipped with a
resistor spark plug, use the same type for replacement.

CLEANING THE CARBURETTOR
7.6.1.
To clean the carburettor (fig.8):
1. Unscrew the bolt on the bottom of carburettor.
2. Push the float up four to five times, then clean sediment cup with fuel.
NOTE:
Ensure you replace the O ring when putting the sediment cup back.
7.7.
WINTER AND LONG TERM PUMP STORAGE
7.7.1.
STEP 1: ENGINE STORAGE.
If the unit is not to be used for more than
one month the following procedure should be followed.
1. Top-up engine oil to maximum.
2.
Drain petrol from the fuel tank, fuel line, fuel tap and carburettor.
3. Pour one teaspoon of engine oil through the spark plug hole, pull the recoil
starter several times and replace the spark plug. Then pull the starter slowly until an increase in pressure is felt indicating that the piston has
commenced its compression stroke and leave it in this position. This closes both the intake and exhaust valves and prevents the inside of the
cylinder from rusting.
7.7.2.
STEP 2: PROTECT FUEL SYSTEM
WARNING!
Petrol is extremely flammable and potentially explosive.
DO NOT
perform maintenance on petrol associated components
where there is any source of ignition present such as cigarettes, sparks, naked flame or hot surfaces.
FUEL ADDITIVE:
Fuel can become stale when stored for over 30 days. Stale fuel causes acid and gum deposits to form in the fuel system or on essential
carburettor parts. Please use fuel stabilizer to keep fuel fresh. Run the engine for 2 minutes to circulate the stabilizer throughout the fuel
system before storage.
DRAIN FUEL
If fuel in the engine has not been treated with a fuel stabilizer, it must be drained into an approved container. Run the engine until it
stops from lack of fuel. Remove the hex screw from the carburettor (fig.8) then drain the fuel from the tank, carburettor, and tube. Screw
the carburettor drain hex screw back once the fuel has been completely drained.
7.7.3.
STEP 3: CHANGE OIL
(See sections 7.1 - 7.4)
7.7.4.
While engine is still warm, drain oil from crankcase. Remove the hex screw from the crankcase (fig.5). Drain the oil to a container. Refill
with recommended grade oil (SAE 10W-30).
IMPORTANT:
• If the pressure washer is to be stored with fuel in the fuel tank and carburettor, it is important to reduce the hazard of fuel vapour ignition.
• Select a well-ventilated storage area away from any appliance that operates with a flame, such as a furnace, water heater, or clothes
dryer. Also avoid any area with a spark-producing electric motor, or where power tools are operated.
• If possible, avoid storage areas with high humidity, this will promote rust and corrosion.
• Place the pressure washer on a level surface. Tilting can cause fuel or oil leakage.
