Working With Detergents - Stanley P2350S Owner's Manual

WORKING WITH DETERGENTS

Working with detergent ensures a quick soaking of the dirt, and allows
the high-pressure water to penetrate and remove the dirt more
effectively. Always spray detergent on a dry surface. Do not pre-soak
area with plain water. Wetting the surface first dilutes the detergent
and reduces its cleaning ability.
To siphon and apply detergent, you must operate the pressure washer
on low pressure— adjust the nozzle to low pressure (see below for
instructions. This provides a gentle application of detergent, with the
pressure equivalent to a low-set garden hose. The high-pressure setting
is used for cleaning; you cannot apply detergents when working at high-
pressure. Always test detergent in an inconspicuous area before use.
Step 1

Attach the variable wand into the spray gun by turning and
threading the wand into the gun until tight.
To siphon detergent, adjust the wand to the low pressure setting by
sliding the wand away from you.
Step 2
Set the adjustable nozzle to the low-pressure setting. The nozzle must
be set in the low-pressure position to apply detergent. Apply high
pressure spray to small area and then check surface for damage. If no
damage is found, you can assume it is okay to continue cleaning. Start
at top of area to be rinsed, working down with same overlapping strokes
as used for cleaning.

OPERATION
Step 3


Step 4
Turn on the pressure washer. Pull trigger to operate unit. The liquid
detergent will automatically mix with water and be discharged through
nozzle. Apply detergent to a DRY work surface, from bottom to top.
Step 5
Allow detergent to remain on the surface for a short time before rinsing.
Do not allow detergent to dry on surface.
Step 6
Rinse with clean water under high-pressure. On a vertical surface, rinse
from the bottom up, then rinse from the top down to avoid streaking.
Hold nozzle 6-8 inch from the work surface at a 45° angle.
Step 7 (End of detergent application)
When you have finished using the detergent injection system, remove
detergent suction tube from bottle and insert into 1 gallon (5L) of fresh
water. Siphon water at low-pressure for one to two minute so that all
detergent is flushed through system. Remove detergent bottle and rinse
it until it is thoroughly cleaned.
Damage may occur to painted surface if chemical is allowed to
dry on surface. Wash and rinse a small section at a time. Avoid
working on hot surfaces or in direct sunlight
Failure to clean properly will cause the injection system to
become clogged and inoperable.
Never use:





These chemicals will harm the unit and will damage the surface
being cleaned..
