8 Press the on/off button to start pressure washer

if the wand is not securely locked into place, it could be ejected under

high pressure when operating the gun, possibly causing injury or damage.

When low-pressure is required, grasp collar and slide collar and nozzle away from the gun.

4.2 HIGH PRESSURE/LOW PRESSURE

Do not move the nozzle to adjust pressure while the trigger is squeezed.

The high pressure nozzle position is intended for cleaning. When high pressure is required, grasp

collar and slide the collar and nozzle toward the gun.

NOTE: Make sure the collar is pulled to the extreme rear position to lock the nozzle in the high

pressure position.

12- ENG

D28921

4.3 ADJUSTABLE SPRAY NOZZLE

The adjustable spray nozzle can adjust spray from fan to pencil point in both the high and low

pressure positions. The spray is adjusted by turning the nozzle.

The pencil point spray adjustment is very aggressive. We recommend that

for most cleaning applications, a twenty degree (20°) spray angle be used

to avoid damage to the surface being sprayed.

NOTE: The pressure of the spray on the surface you are cleaning increases as you move the wand

closer to the surface.

To increase angle to a fan spray, turn counterclockwise

To decrease angle to pencil point spray, turn clockwise

4.4 HIGH PRESSURE/TURBO SPRAY

Do not move the nozzle to adjust pressure.

The high pressure rotary nozzle position is intended for maximum cleaning effect. Keep the spray

lance min. 6” to 8” away from the cleaning surface at all times.

Rotary Spray

13- ENG

D28921

4.6 CLEANING TECHNIQUES

When cleaning with the pressure washer, some cleaning tasks can be solved with water alone, but

for most tasks it is advantageous to use a detergent. A detergent ensures a quick soaking of the

dirt allowing the high pressure water to penetrate and remove the dirt more effectively.

The low pressure position provides a gentle application of chemicals. This position is also

recommended to rinse a surface after wax application or for other applications which require the

low pressure of a garden hose. Low pressure is the equivalent of a garden hose set at the lowest

output to properly apply chemical. FOR CHEMICAL APPLICATION, SLIDE COLLAR ACCORDING

TO SECTION 4.2.

4.5 USE OF CLEANING CHEMICALS

only use cleaning chemicals recommended for pressure washers.

1 Insert the relevant suction tube (2) beneath the chemical solution reservoir.

2 Fill the reservoir (1) with suitable cleaning solution.

3 Insert the chemical solution reservoir into the relative compartment in the rear part of the

machine

4 Secure the chemical solution reservoir with the screw provided

5 Move the adjustable nozzle forward to the low pressure position by sliding collar toward the

nozzle. The chemical will automatically be mixed with the water and discharged through the

nozzle.

NOTE: When the adjustable nozzle is moved to the high pressure position, chemical will not be

discharged.

APPLICATION OF SOAP DEGREASER

1. Apply the solution to a DRY work surface. NOTE: WETTING THE SURFACE FIRST IS NOT

RECOMMENDED, AS IT DILUTES THE DETERGENT AND REDUCES ITS CLEANING ABILITY.

On a vertical surface, apply horizontally from side to side starting from the bottom to avoid

streaking.

2. Allow chemical to remain on the surface for a short time before rinsing

Damage may occur to painted surface if chemical is allowed to dry on the

surface. Wash and rinse a small section at a time. Avoid working on hot

surfaces or in direct sunlight.

3. Rinse with clean water under high pressure. On a vertical surface, first rinse from the bottom

up, then rinse from the top down. Hold nozzle 6 to 8 inches from the work surface at a 45°

angle using the flat spray as a peeling tool rather than a scrub brush.

NOTE: Insure that the chemical injection system is completely clean prior to switching from one

chemical to another.

14- ENG

D28921

APPLICATION OF LIQUID VEHICLE WAX

1. Immediately after cleaning, apply Pressure Washer Liquid Vehicle Wax using low pressure.

Pour wax into chemical solution reservoir.

2. Apply the wax sparingly in an even layer. Apply to wet surfaces from the bottom up for even

distribution and to avoid streaking.

3. Rinse off the surplus wax. NOTE – IF SURPLUS WAX IS NOT REMOVED, A HAZY FINISH

MAY RESULT.

4. Wipe dry to reduce water spotting.

4.7 END OF OPERATION

When you have completed use of the chemical injection system, remove tube from container,

continue to run in low pressure position and flush clean water through the chemical tank until it is

thoroughly cleaned. NOTE: Failure to clean properly will cause the injection system to become

clogged and inoperable.

l Stop the unit by pressing the ON/OFF button to the "OFF" position.

l Disconnect electrical plug.

l Turn off water and depressurize unit by squeezing trigger.

Turn off water supply and squeeze trigger to depressurize the unit. Failure

to do so could result in personal injury due to discharge of high pressure

water.

l Disconnect the high pressure discharge hose and the water inlet hose.

5.2 NOZZLE

The high pressure/low pressure adjustment of the nozzle should be lubricated regularly.

Clogging of the nozzle causes the pump pressure to be too high and cleaning is immediately

required.

1. Separate the nozzle from the wand

2. Clear the nozzle.

5.0 MAINTENANCE

5.1 CONNECTIONS

Connections on Pressure Washer hoses, gun and spray wand should be cleaned regularly and

lubricated to prevent leakage and damage to the o-rings.

3. Flush the nozzle backwards with water

4. Reconnect the nozzle to the wand

NOTE: Completely screw the nozzles on the wand up to the complete lock. (see picture)

Restart the pressure washer and depress the trigger on the spray gun. If the pressure is still too

high, repeat above items 1-4.
