Maintenance

Storage

CAUTION: Always store your pressure washer in a 

location where the temperature will not fall below 32°F 

(0°C). The pump in this machine is susceptible to 

permanent damage if frozen. FREEZE DAMAGE IS 

NOT COVERED BY WARRANTY.
ATTENTION: Toujours entreposer la laveuse à 

pression dans un endroit où la température ne sera 

pas inférieure à 32°C (0 °F). La pompe sur cette 

machine est susceptible de subir des dommages si 

elle est exposée au gel. LES DOMMAGES DUS AU 

GEL NE SONT PAS COUVERTS PAR LA GARANTIE
PRECAUCIÓN: Siempre almacene la hidrolavadora en 

una ubicación donde la temperatura no llegue a ser 

menor que 32ºF (0ºC). La bomba en esta máquina es 

susceptible a daño irreversible si se congela. DAÑOS 

POR CONGELAMIENTO NO ESTAN CUBIERTOS POR 

GARANTÍA.

1. Stop the pressure washer, squeeze spray gun 

trigger to release pressure.

2. Detach water supply hose and high pressure hose.
3. Turn on the machine for a few seconds, until  

remaining water exits. Turn engine off immediately.

4. Drain the gas and oil from the engine.
5. Do not allow high pressure hose to become kinked.
6. Store the machine and accessories in a room 

which does not reach freezing temperatures.

CAUTION: Failure to follow the above directions will 

result in damage to your pressure washer.
ATTENTION: Le non-respect des directives ci-dessus 

entraînera des dommages à la laveuse à pression.
PRECAUCIÓN: No seguir las instrucciones anteriores 

pueden resultar en daños de tu hidrolavadora.

When the pressure washer is not being operated or is 

being stored for more than one month, follow these 

instructions:
1. Replenish engine oil to upper level.
2. Drain gasoline from fuel tank, fuel line, fuel valve 

and carburetor.

3. Pour about one teaspoon of engine oil through the 

spark plug hole, pull the starter grip several times 

and replace the plug. Then pull the starter grip 

slowly until you feel increased pressure which 

indicates the piston is on its compression stroke 

and leave it in that position. This closes both the 

intake and exhaust valves to prevent rusting of 

cylinder.

4. Cover the pressure washer and store in a clean, 

dry place that is well ventilated away from open 

flame  or sparks. 

NOTE: 

The use of a fuel additive, 

such as STA-BIL

®

, or an equivalent, will minimize 

the formulation of fuel deposits during shortage. 

Such additives may be added to the gasoline in the 

fuel tank of the engine, or to the gasoline in a 

storage container.

After Extended Storage

CAUTION: Prior to restarting, thaw out any 

possible ice from pressure washer hoses, 

spray gun or wand.
ATTENTION: Avant de redémarrer, faire 

fondre la glace se trouvant sur les boyaux, le pistolet 

pulvérisateur ou la lance de la laveuse à pression.

PRECAUCIÓN: Antes de reiniciar, descongele 

cualquier posible hielo en las mangueras, pistola 

pulverizadora o lanza.

Engine Maintenance

During the winter months, rare atmospheric conditions 

may develop which will cause an icing condition in the 

carburetor. If this develops, the engine may run rough, 

lose power and may stall. This temporary condition can 

be overcome by deflecting some of the hot air from the 

engine over the carburetor area. 

NOTE:

 Refer to the 

engine manufacturer's manual for service and mainte

-

nance of the engine.

Preventative Maintenance

1. Check to see that the water pump is properly 

lubricated.

2. Follow 

Winterizing Procedures

 to prevent freeze 

damage to the pump and coils.

3. Always neutralize and flush detergent from system 

after use.

4. If water is known to be high in mineral content, use 

a water softener in your water system or de-scale 

as needed.

5. Do not allow acidic, caustic or abrasive fluids to be 

pumped through system.

6. Always use high grade quality Landa cleaning 

products.

7. Never run pump dry for extended periods of time.
8. Use clean fuel-kerosene, No. 1 fuel oil or diesel. 

Replace fuel filter every 100 hours of operation. 

Avoid water contaminated fuel as it will seize up
