SHUTTING DOWN AND CLEAN-UP

STEP 1:

 Remove detergent suc-

tion tube from container and insert 
into one gallon of fresh water. Slide 
nozzle forward for low pressure or 
to connect black detergent nozzle. 
Pull trigger on spray gun and siphon 
water for one minute.

STEP 2:

 Turn off the engine.

STEP 3:

 Turn  off  water 

supply.

STEP 5:

 Disconnect the garden 

hose from the water inlet on the 
machine.

STEP 6:

 Disconnect the high 

pressure hose from discharge 
nipple.

STEP 7:

 Engage 

the spray gun safe-
ty lock.

STEP 4:

 Press trig-

ger to release water 
pressure.

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.

  1.  Stop the pressure washer, squeeze spray gun trig-

ger to release pressure.

  2.  Detach water supply hose and high pressure hose.

  3.  Turn on the machine for a few seconds, until  re-

maining 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.

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 pressure washer and store in a clean, dry 

place that is well ventilated away from open fl ame  
or sparks. 

NOTE: 

The use of a fuel additive, such as 

STA-BIL

®

, or an equivalent, will minimize the formula-

tion of fuel deposits during shortage. Such additives 
may be added to the gasoline in the fuel tank of the 
engine, or to 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.

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 defl ecting 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.
