Distance from cleaning surface
Another factor that determines the impact force of the
water is the distance from the spray nozzle to the
cleaning surface. The impact force of the water is
increased 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.
The impact force can be varied by controlling the three
previously noted items. 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 as this may
cause breakage.
The surest 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 from and 45
degrees to the cleaning surface, and 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.
