Detergent Injectors - Echo PWE-1800 Manuel De L'opérateur

HOW TO CLEAN
You can vary the force of your power washer by controlling:
• The angle of the surface being cleaned
• The distance of the nozzle from the surface being cleaned
- Never use a narrow high pressure stream of water or the turbo lance on soft
surfaces susceptible to damage.
- Use the high/low nozzle lance when cleaning windows. Be sure to adjust the
nozzle to low spray and place the nozzle approximately four to five feet away
from the window with the nozzle at forty five degree angle. Squeeze the
trigger and vary the spray pattern and angle until optimum cleaning efficiency
is achieved (Fig. 21).

DETERGENT INJECTOR/STORAGE
• Typically, there are different power washer detergents for specific applications,
such as auto, motorcycle, boat and universal. Hardware stores or home centers
also have power washer detergents for different cleaning projects. The cleaning
solution should be the consistency of water in order to prevent clogging your
detergent tank and nozzle.
• This system applies detergent under low pressure. The cleaning power of the
detergents is enhanced when applied with low pressure; and time is allowed to
break down the dirt and grime. The combination of low pressure and chemical
action is very effective and can be better than scrubbing if applied properly.
Always spray detergent on a dry surface, do not pre-soak area. Wetting the
surface first dilutes the detergent and reduces its cleaning ability. Do not allow
detergent to dry on surface. On vertical surfaces being cleaned, apply detergent
to lower surfaces and work your way up to prevent detergent from causing
streaks in the dirt and grime. Rinse detergent by pressure washing from bottom
up for same reason.
• If a stain is particularly tough, it may be necessary to reapply the detergent
and use a bristled brush to scrub the stain. Subsequent power washing after
brushing should successfully complete your cleaning job.
