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 .
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

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 .
