Operating Instructions and Parts Manual
Operation (Continued)
When pulling the starter rope, make sure to
keep your hand and arm clear of the engine
and cart components.
Never let the starter rope return by itself.
Doing so could jam the recoil system.
8. If the engine does not start after two or three pulls or
if the rope is hard to pull, squeeze the gun trigger to
release the pressure that has built up in the high pressure
hose. Repeat Steps 7 and 8 until the engine starts.
INITIAL HIGH PRESSURE RINSE
Spray the cleaning surface with water to clear off any dirt
or grime that may have collected on the surface. Doing so
allows the detergent to attack the deep down dirt that has
worked its way into the cleaning surface.
Trigger the gun 3 to 5 times to get any trapped air out of the
system.
ADJUSTING THE SPRAY FAN ANGLE
Five quick connect tips are available for this pressure washer.
The tips have a range of spray fan angles, ranging from 0°,
narrow high impact, to a 65° wide fan spray.
Pressure can also be adjusted by moving closer or further
away from the cleaning surface and by adjusting the spray fan
angle as shown.
ANGLE TO THE CLEANING SURFACE
When spraying water against a surface, you can generate
maximum impact by striking the surface head on. However,
this type of impact can cause dirt particles to embed in the
surface and can prevent the desired cleaning action.
The optimum angle for spraying water against a cleaning
surface is 45 degrees.
Spray water against a surface at a 45 degree angle to achieve
the most beneficial impact force and to efficiently remove
debris.
DISTANCE FROM CLEANING SURFACE
The distance between the spray nozzle and the cleaning
surface is another factor that affects the impact force of the
The color of the tip shows what spray angle it is:
Red – 0° – Maximum Duty *
Yellow – 15° – Heavy Duty
Green – 25° – General Duty *
White – 40° – Light Duty *
Black – 65° – Low Pressure Detergent

water. The impact force of the water increases as the nozzle
is moved closer to the surface.
HOW TO AVOID DAMAGING SURFACES
Damage to cleaning surfaces occurs because the impact force
of the water exceeds the durability of the surface. You can
vary the impact force by controlling the spray nozzle angle
to the cleaning surface and the distance from the cleaning

surface and by changing the spray nozzle. NEVER use a
narrow high impact stream on a surface that is susceptible to
damage. Avoid spraying windows with a narrow high impact
stream. Doing so may break the window. The most sure way
to avoid damaging surfaces is to follow these steps:
1. Before triggering the gun, make sure the quick connect
nozzle you are using is appropriate for the application.
2. Place the spray nozzle approximately 4-5 feet (1,22-1,52
m) away from the cleaning surface. Then hold the lance
and spray nozzle at a 45 degree angle to the cleaning
surface. Trigger the gun.
3. Vary the fan pattern spray angle and the distance to the
cleaning surface until optimum cleaning efficiency is
achieved without damaging the surface.
DETERGENT APPLICATION
NOTE: Use only detergents formulated for pressure washers.
Test detergent in an inconspicuous area before use. Do not
use bleach with this pressure washer unit.
DETERGENTS
The use of detergents can dramatically reduce cleaning time
and assist in the removal of difficult stains. Many detergents
are customized for pressure washer use on specific cleaning
tasks. Pressure washer detergents are as thick as water.
Using thicker detergents – like dish soap – will clog the
chemical injection system and prevent the application of the
detergent.
Once applied to a cleaning surface, detergents take time
to break down dirt and grime. Detergents work best when
applied at low pressure.
You can effectively clean surfaces by combining the chemical
action of detergents with high pressure rinses. On vertical
surfaces, apply the detergent starting at the bottom and
work your way upward. This method prevents the detergent
from sliding down and causing streaks. Begin high pressure
rinsing at the top and work your way downward. On
particularly tough stains, use a brush in combination with
detergents and high pressure rinsing.
1. Follow manufacturer's label directions for mixing correct
concentrations of soap/detergents. The soap detergent to
water ration through the pump is approximately 10% (1
to 10).
2. Insert the filter end of the clear plastic detergent tube
into the detergent container.
3. Use the black 65° quick connect spray nozzle.
GENERAL CLEANING TIPS
1. Apply the detergent so that it thoroughly covers the
cleaning surface. Apply the detergent from bottom to
top to prevent the detergent from sliding down and
streaking. Wait a couple of minutes for the detergent
to break down the dirt and grime. Use a brush to lightly
scrub heavily soiled areas. Never allow the detergent to
dry on the cleaning surface.
2. To rinse: replace black 65° spray nozzle with another color
nozzle.

nozzles.
