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.

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. Before triggering
the gun, adjust the nozzle to a wide
fan pattern and slowly adjust it to the
desired spray pattern. Using a wide fan
pattern helps you avoid applying too
much concentrated spray to the surface
which can cause damage.
aDjuStING FaN PatterN
Adjust the angle of spray coming out
of the lance by rotating the nozzle. The
spray pattern will vary from a 0° narrow
high impact stream to a 60° wide fan
spray (See Figure 11 ).
A narrow stream has high impact
force on the cleaning surface and
results in maximum deep cleaning in
a concentrated area. However, this
narrow high impact spray can damage
some surfaces so use it cautiously.
A wide fan pattern will distribute the
impact of the water over a larger area
resulting in excellent cleaning action
with a reduced risk of surface damage.
Clean large surface areas quickly using a
wide fan pattern.

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.

The distance between the spray nozzle
and the cleaning surface is another
factor that affects the impact force
of the water. The impact force of the
water increases as the nozzle is moved
closer to the surface.

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 nozzle's fan pattern, the
nozzle's angle to the cleaning surface,
and the nozzle's distance from the
cleaning surface. Never use a narrow
high impact stream or a Turbo/rotary
nozzle on a surface that is susceptible
to damage. Avoid spraying windows
with a narrow high impact stream or
turbo nozzle. Doing so may break the
window. The most sure way to avoid
damaging surfaces is to follow these
steps:
1. Before triggering the gun, adjust the
nozzle to a wide fan pattern.
2. Place the nozzle approximately 4-5
feet away from the cleaning surface.
