BEAST Electric Pressure Washers
Rev: April 2015
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. 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.
Use only detergents designed for use with pressure washers; all
detergents should be thin liquids, about the consistency of milk. Using
thicker liquids such as car wash concentrate or dish soap will not allow
the detergent to siphon.
Step 1
P1450B, P1500B, P1600B: Attach yellow detergent bottle to the spray
gun as shown in Figure below.
Step 3
Gently remove detergent container and fill with detergent.
Re-attach containers back into position.
Set pressure washer to low pressure by pulling the spray end of the
wand out/downward.
Step 4
Turn the pressure washer to “ON”. Pull trigger to operate the 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 2
P1750B and P1800B ONLY:
Set the adjustable nozzle to the low
-pressure setting. The nozzle must be set in the low-pressure
position to apply detergent. Apply low pressure spray to a 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.
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:
Bleach, chlorine products and other corrosive chemicals
Liquids containing solvents (i.e., paint thinners, gasoline,
oils)
Tri-sodium phosphate products
Ammonia products
Acid-based products
These chemicals will harm the unit and will damage the surface
being cleaned.
.
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 minutes so that all
detergent is flushed through system. Remove detergent bottle and rinse
CAUTION
OPERATION
P1750B, P1800B, P2000B: Attach adjustable wand to spray gun.
