Working with Detergents
When cleaning with the pressure washer, some cleaning tasks
can be solved with water alone, but for most tasks cleaning
with detergent allows for more effective dirt removal.
m
WARNING!
Use only detergents specifically designed
for use with pressure washers, such as Sun Joe
®
HOUSE +
DECK WASH (SPX-HDC1G), Sun Joe
®
SNOW FOAM AUTO
WASH (SPX-FCS1G), or Sun Joe
®
HEAVY DUTY CLEANER
(SPX-APC1G). DO NOT USE household detergents, acids,
alkaline solutions, bleaches, solvents, flammable material, or
industrial grade solutions. These could damage the pressure
washer. Many detergents may require mixing prior to use.
Prepare the cleaning solution as instructed on the solution
bottle.
1. Set the adjustable nozzle to the fan-spray setting (Fig. 16).
2. Remove the detergent compartment cap with suction
tube. Gently pull the onboard detergent compartment out
of its storage position. (Figs. 17 – 18).
3.
Fill the tank with detergent designed specifically for use
with pressure washers (Fig. 19).
4. Insert the suction tube back into the tank and cap the tank
closed. Push the tank back into storage position on the
unit.
m
CAUTION!
Always test the detergent in an
inconspicuous area before use.
5. Turn on the pressure washer. Pull the trigger to operate
the unit. The liquid detergent will automatically mix with
water and be discharged through the nozzle.
6. Apply detergent from the bottom to the top of the dry
surface to be cleaned.
NOTE:
Wetting the surface first is not recommended as it
dilutes the detergent and reduces its cleaning ability.
7. Allow the detergent to remain on the surface for a short
time before rinsing. Do not allow the detergent to dry on
the surface.
m
CAUTION!
Damage may occur to painted surfaces if
the detergent 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.
8. Rinse with clean water under high pressure. When working
on a vertical surface, rinse from the bottom up, then rinse
from the top down to avoid streaking. Hold the nozzle 6-8
inches away from the work surface at a 45° angle.
9.
When you have finished using the detergent injection
system, remove the detergent suction tube from the
detergent tank and insert it into 1.3 gal (5 L) of fresh water.
Siphon water for one minute so that all the detergent is
flushed through the system. Remove the detergent
tank
and rinse it until it is thoroughly cleaned.
m
CAUTION!
Failure to follow these cleaning instructions
will cause the injection system to become clogged and
inoperable.
