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.

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.
