Figure 11 - Optimum angle to cleaning
surface
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 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 .

4. DeTerGeNT APPLICATION
NOTe:
Use only detergents formulated for pressure washers.
Test detergent in an inconspicuous area before use .
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 bottom and work your way upward . 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 ratio through the pump is approximately 12% (1 to
8) .
2 . Insert the filter end of the clear plastic detergent tube into
the detergent container .
3. Install 65º (Black) Low Pressure Detergent Tip in the quick
connect fitting on the end of the lance .
neVer replace quick connect tip when
gun is triggered. Always engage trigger
lock on gun before removing or installing quick connect tips.
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. Replace black 65º quick connect tip with the yellow 15º tip
and complete final rinse .
neVer replace quick connect tip when
gun is triggered. Always engage trigger
lock on gun before removing or installing quick connect tips.
3. NOTE: After using detergents, flush the suction system by
placing the detergent suction tube into a bucket of clean
water and running unit with black 65º tip flushing clean
water from tank through the pump .
Operation
The color of the tip shows what spray angle it is:
red – 0º – Maximum Duty *
Yellow – 15º – Heavy Duty *
Green – 25º – General Duty *
White – 40º – Light Duty *
Black – 65º – Low Pressure Detergent
* = Not Included
NOTe:
Use orifice size 2.5
