High pressure fluid in the hoses can be very dangerous.
If the hose develops a leak, split or rupture due to any
kind of wear, damage or misuse, the high pressure
spray emitted from it can cause a fluid injection injury or
other serious bodily injury or property damage.

ALL FLU/D HOSES MUST HAVE STRAIN RELEFS ON

BOTH ENDS. The strain reliefs help protect the hose
from kinks or bends at or close to the coupling, which
can result in hose rupture.

TlGHTEN all fluid connections securely before each
use. High pressure fluid can dislodge a loose coupling
or allow high pressure spray to be emitted from the
coupling.

NEVER use a damaged hose. Before each use, check
entire hose for cuts, leaks, abrasion, bulging cover, or
damage or movement of the hose couplings. If any of
these conditions exist, replace the hose immediately.
DO NO7 try to recouple high pressure hose or mend it
with tape or any other device. A repaired hose cannot

contain the high pressure fluid.

adjustable unloader valve that permits operation at

less than maximum pressure. To reduce pressure,

for special cleaning applications, turn the pressure
control knob on the unloader counterclockwise, as
needed.

7.

ALWAYS observe the followinq CAUTIONS to avoid

costly damage to the pressu‘;e washer.

CAUTION

DO NOTallow the pressure washer to idle for more
than 10 minutes. Doing so may cause the

recirculating water to overheat and seriously
damage the pump. Turn off the pressure washer if it

will not be spraying or cleaning at least every 10

minutes. If heated inlet water is used, reduce this

time further,
DO NOT run the pump dry, which will quickly

damage the pump. Be sure the water supply is

fully turned on before starting the pump.
DO NOToperate the pressure washer with the inlet

water screen removed. This screen helps keep

abrasive sediment out of the pump, which could
clog or scratch the pump. Keep this screen clean.

Chemical Injector

BE SURE that all chemicals used in the chemical
injector are compatible with the wetted pans of the
hose, gun, wand and tip, as given in the Technical Data
(page 22). Always read the chemical manufacturer’s
literature before using any chemical in this pressure

washer.

826: A downstream chemical injector is provided with
the pressure washer. Insert the chemical strainer
(attached with clear tubing to the chemical injector) into
the container of chemical. Turn the control ring on the
adjustable nozzle clockwise. This causes a drop in
pressure that actuates the chemical injector. Close the
adjustable nozzle to deactivate the chemical injector
and produce high pressure for rinsing. The flowrate of
the chemical is regulated by turning the chemical
adjustment knob on the injector. Maximum chemical
flow is at a full two turns counterclockwise from the
closed (clockwise) position.

1235: The chemical injector is an accessory. See the

chemical injector instruction manual.

WARNING

DO NOT attempt to open or close the adjustable

nozzle when the spray gun is in use. Be sure that

the trigger safety latch on the gun is in the “ON”

position before adjusting to avoid serious bodily
injury or fluid injection.

r

Check the distance that you will need to hold the spray
nozzle from the surface by test spraying on a scrap of
similar material. For soft surfaces, such as wood, hold
nozzle 3 ft (1 m) from the surface and gradually bring it
closer, checking to see if the high pressure spray is
damaging the surface.

Mist the wet surface with cleaning solution. Let it soak
briefly, then use the high pressure rinse to “chisel” off
the soil. Keep the nozzle at an angle to the surface and
at a distance determined to be best for the surface. If
some soil remains, repeat the procedure, letting the
chemical soak a little longer. Stubborn soil can be
cleaned off better with a stronger, heated cleaning
solution.

Protect surfaces that might be damaged by the cleaning
solution or the high pressure spray. Rinse the solution
before it dries.

DO NOT pump caustic materials; such materials

may corrode the pump components.
