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.
