unwrap and straighten high pressure
hose prior to and during each use and
do not allow it to become kinked. The
high pressure hose features an outer
covering that provides strength to the
hose. If the outer covering becomes
damaged, stop using the hose and
replace it immediately. A kinked or
damaged hose can develop a high
pressure leak and result in a possible
injection or other serious personal injury.
To prevent damage to the outer covering:
Inspect the hose before every use.
Fully unwrap and straighten hose before use.
Do not allow the high pressure hose to be kinked.
eep hose away from hot surfaces and sharp
edges.
Do not pull unit by high pressure hose.
Do not allow hose to be crushed or wrapped
around objects.
WASHING WITH DETERGENT
Do not use household detergents, acids, alkalines,
bleaches, solvents, flammable material, or
industrial grade solutions, which can damage the
pump or cause property damage.
We recommend the use of a good quality pressure
washer detergent for use with this pressure
washer. Please follow the instructions on the
container.
Most automobile detergents are a combination of a
detergent and a wax solution, (wash/wax liquid).
These tend to be a thick viscous liquid. The
viscosity (thickness) of the detergent will increase
in cold weather. It is recommended that this type of
detergent is diluted with warm water before filling
the container.

OPERATION
When using combination wash and wax solutions
we recommend that they are diluted before use. As
a general guide we would recommend a dilution
rate of 50/50. However a trial and error process
would determine the ideal dilution rate for a
particular detergent.
Fill a suitable container with pressure washer
detergent.
Fit the detergent hose to the detergent hose
connection point, Fig.17.
Install the black soap nozzle on the spray lance.
Submerge the end of the detergent pick up hose
into your container of pressure washer detergent,
Fig.18. Suction and mixing will occur automatically
as the water flows through the pump.
Squeeze the trigger and wait approximately 5
seconds for the detergent to appear.
Spray the detergent on a dry surface using long,
even, overlapping strokes. To prevent streaking, do
not allow detergent to dry on the surface.
Before shutting off the engine:
Fill the soap container with clean water.
Spray the clear water through the spray lance until
the tank is empty.
If any detergent remains in the spray, repeat with a
second container of clean water.
Shut off the engine.
NOTE: Shutting off the engine will not relieve
pressure in the system. Pull trigger to release water
pressure.
RINSING WITH THE PRESSURE WASHER
Turn off the pressure washer and shut off the water
supply. Pull trigger to release water pressure.
Engage the lock out on the trigger gun by pushing
up on the lock out until it clicks into the slot.
Remove the soap nozzle by placing hand over
nozzle then pulling back the quick-connect collar.
Place nozzle in the nozzle storage area on the top
of the machine.
Select the right nozzle for the job. See the chart on
page 14 for selecting the appropriate nozzle.
Start at the top of the area to be rinsed and work
down, overlapping the strokes.
MOVING THE PRESSURE WASHER
Always carry this product using the handle and
never place the unit in any position other than
upright on its rubber feet. We recommend lifting
this product with another person.
DO NOT attempt to move the unit by pulling on any
of the hoses.
HIGH ALTITUDE OPERATION
Your engine is configured for operation below 3000
feet altitude at the factory. Your engine must be
reconfigured for operation above 3000 feet altitude.
Operating the engine with the wrong engine
configuration at a given altitude may increase its
emissions, decrease fuel efficiency, degrade
performance, and cause irreversible damage.
Engines configured for high altitude operation
cannot be operated in standard altitude conditions.
A qualified service center should ensure that your
engine is properly configured for your location.

OPERATION
USING AN ALTERNATIVE WATER SUPPLY
If you don’t have an outside tap, or a hose pipe
then you may wish to use a bucket of water to draw
water into your pressure washer. Using water from
a bucket, water butt, a tank or barrel will save the
amount of water you use.
Always connect the filter onto the end of the water
supply hose before submerging in water, Fig.19.
Once submerged in the water you are ready to go.
The filter on the water supply hose will help prevent
grit and stones from being drawn into and used by
the pressure washer. Fig. 19

that could eject the nozzle with some
force. Failure to follow these instructions
could result in an eye injury or other
serious personal injury.
To free any foreign materials clogging or restricting
the nozzle, blow out or remove debris with a
straightened paper clip or the cleaning needle,
Fig.20.
Using a garden hose, flush debris out of nozzle by
back flushing (running the water through the nozzle
backwards or from the outside to the inside).
Reconnect the nozzle to the spray lance.
Turn on the water supply and start the engine.
CLEANING/REPLACING THE AIR FILTER
A dirty air filter will cause starting difficulty, loss of
performance, and shorten the life span of the
engine. Check the air filter monthly. For best
performance, replace the air filter at least once a
year.
Unscrew the two filter cover knobs, Fig.21 and lift
away the filter cover, Fig.22.
Using a damp cloth, wipe the air filter cover and
