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.
3. 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.
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.

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 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
