Detergent
Use the detergent setting to apply detergent. Some cleaning tasks can be completed with water alone,
but for most tasks the removal of dirt becomes more effective if a detergent is used.
NOTE: Only use mild, environmentally friendly detergents. Never use aggressive chemicals, abrasive
detergents or similar to avoid damage to your health, the product and the environment.
Unscrew the cap (7b) to open the tank (7c) and ll
with suitable detergent
Screw the cap back onto the tank.
Adjust the detergent ow with the regulator (7a) on
the cap (7b)
WARNING! Avoid skin contact with detergents, in particular contact with eyes! If detergent
gets in your eyes ush your eyes with clean water and seek immediate medical attention!

The following cleaning procedure will ensure that you achieve the most benecial results in the shortest
amount of time.
• Surface preparation
Clear the working area and make sure that all windows and doors are closed tightly. Make sure that all
plants and trees adjacent to the cleaning area are protected by a drop cloth.
• Initial high pressure rinse
The next step is to spray the cleaning surface with water to clear off any dirt or grime that may have
collected on the surface. If you use detergent, this will allow your detergent to attack the dirt that has
worked its way into the cleaning surface. Before triggering the gun, adjust the variable nozzle to a wide
spray pattern and slowly adjust to the desired spray pattern. This will help you avoid applying too much
pressure to the surface that could cause damage.
• Detergent application
Only use detergents formulated for pressure washers. Test the detergent in an inconspicuous area before
use. Follow the manufacturer’s label directions for mixing the correct concentrations of detergent to
water.

1. Unscrew the top of detergent applicator and ll with detergent.
2. Put the top of detergent applicator back on.
3. Attach the detergent nozzle to the spray gun.
4. Apply the detergent so it thoroughly covers the cleaning surface. Apply from bottom to top to prevent
the detergent from sliding down and streaking.
5. Allow the detergent to remain on the surface for a few minutes. This is a good time to use a brush to
lightly scrub heavily soiled areas. Never allow detergent to dry on the cleaning surface.
6. Remove detergent applicator from gun and replace with the lance.
7. Rinse detergent from surface.
8. Rinse the detergent applicator with clean water following each use.
9. Final rinse. Make sure you thoroughly rinse the surface and that all detergent has been removed.
• Shut down
1. Make sure all detergent is ushed from the system.
2. Turn off the motor.
3. Turn off the water supply.
4. Trigger the gun to de-pressurise the system.
5. After each use, wipe all surfaces of the pressure washer with a clean, damp cloth.

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
Angle to the Cleaning Surface
When spraying water against a surface, maximum impact is generated when the water strikes the
surface head on. However, this type of impact tends to cause dirt particles to embed in the surface,
thereby preventing the desired cleaning action.
The optimum angle for spraying water against a surface is 45 degrees.
Avoid Damaging Surfaces
Damage to surfaces occurs because the impact force of the water exceeds the durability of the surface.
Never use a narrow high impact stream or a turbo / rotary nozzle on a surface that is susceptible to
damage.
The surest way to avoid damaging surfaces:
1. Adjust the variable nozzle to a wide spray pattern.
2. Place the variable nozzle approximately 4-5 feet from and 45 degrees to the cleaning surface.
3. Vary the spray pattern, spray angle and the distance to the cleaning surface until optimum cleaning
efciency is achieved without damaging the surface.
General cleaning
Drawing from a barrel
First ensure the machine is switched off before connecting / disconnecting any hoses or attachments.
Instead of attaching the hose from pump to tap, use the supplied hose and lter set placing the lter end
in the water supply.
It is advised that the water supply is on the same level as the washer. If you struggle to get initial suction,
remove the outlet hose from the pump and try drawing again - this reduces the pressure on the pump
making it easier to draw. Once owing, turn engine off and reconnect outlet hose before re-starting.

Post operation / storage
• Do not store the pressure washer outdoors or in a location where it may freeze. Any water left in the
machine, gun or any other components will expand if allowed to freeze, causing damage.
• Always turn the motor off before turning the water supply off.
• Never disconnect the hose from machine while the system is pressurized. To de-pressurize, turn the
motor off, then turn the water supply off and squeeze gun trigger 2-3 times.
Looking After your Product
1. This pressure washer is not meant to pump hot water. Never connect to a hot water supply.
2. Never operate the unit for more than one minute without spraying water. This will cause a heat build-
up that can damage the pump.
3. Only use the nozzles supplied with the machine.
4. Never store the pressure washer outdoors or where it could freeze. The pump will be seriously
damaged. Any components with water left inside will also be damaged, e.g. the pressure gun.
5. Release the trigger when changing the spray pattern. Failure to do so could result in damage.
6. Do not operate the pressure washer with the inlet water screen removed. Be sure to keep the screen
clear of debris and sediment.
7. Make sure you clean the machine every three months and inspect the lter and the nozzle prior to
every use, ensuring there is no debris that may impair use.
Press the accessory towards the spray gun (17) and turn it clockwise to remove it.
