pressure hose from high pres-
sure outlet.

STeP  7:

  Engage 

the  spray  gun  safety 
lock.

STeP 4:

 Press trigger 

to release water pres-
sure.

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 in-
dicates 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.

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 main-
tenance of the engine.
