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 .

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 .
After the engine starts, trigger the gun
3 to 5 times to get any trapped air out
of the system . After the spray becomes
constant, you may need to adjust the
pressure .
Counterclockwise:
Lower pressure
Clockwise:
Higher pressure

ADjuStING the SPrAY FAN ANGle
Five quick connect tips are included
with 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 .

The distance between the spray tip and
the cleaning surface is another factor
that affects the impact force of the
water . The impact force of the water
increases as the tip 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 tip angle to the
cleaning surface and the distance from
the cleaning surface and by changing
the spray tip . 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 tip you
are using is appropriate for the
application .
2. Place the spray tip approximately
4-5 feet (1,22-1,52 m) away from
the cleaning surface . Then hold the
lance and spray tip 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 .
