Product Manual

NOZZLES: The spray nozzle
is a precisely machined orifice
made of hardened stainless
steel. The orifice size is
matched to the output of your
machine to attain the proper flow and pressure in
which your machine was designed. The orifice, or
hole, of the nozzle will enlarge with wear. For
optimum performance, replace the spray nozzle to
maintain the full output pressure of your machine.
The nozzle installed on your machine from the
manufacturer is designed to allow only about 90%
of the water being pumped to discharge out of the
nozzle. The remaining 10% is bypassed back into
the inlet water supply by the unloader/regulator
valve. If an incorrect nozzle size is used, the
maximum flow and pressure of the machine cannot
be achieved and the unloader valve can wear
prematurely. When replacing the nozzle, match to
one size under the flow and pressure output of the
pump.
The nozzle is usually connected to the wand with a
quick coupler. Be sure the collar on the quick
coupler snaps into the locked position, or the
nozzle could be lost when the trigger on the spray
gun is squeezed. Never connect the spray nozzle
directly to the trigger gun without a wand or injury
could result. Never place hands or fingers over the
nozzle tip.
The nozzles generally come in four different spray
angles: 0°, 15°, 25°, and 40°. The different spray
angles of a given size of nozzle does not change
the output pressure of the machine, just the impact
force and surface coverage of the water spray.
The optional 0° nozzle sprays a straight stream
which impacts the surface very hard but does not
cover a very wide area. Use the 0° red nozzle with
care because it can damage the surface you are
spraying with its high impact and long reaching
spray.
The 15° yellow nozzle sprays out a flat stream at a
15° pattern. It gives you less impact power than
the above, but covers a wider area with one pass of
the spray wand. As you back away, the spraying
nozzle from the surface, the spray impact will
decrease.
The 25° green nozzle is wider than the 15° and is
most commonly referred to as the “steam nozzle”.
The steam nozzles are sized to spray less water
than the other high-pressure nozzles, so the water
is discharged at a higher temperature. (Up to
250°F.)
The 40° nozzle spreads the water stream over a
wide area to give you less impact for delicate
surfaces.
OPTIONAL ACCESSORIES:
WET SANDBLASTER: The wet sandblaster is a
system that introduces sand
(or other media such as
baking soda) into the water
stream for abrasive blasting. It
is especially effective for
graffiti or paint removal.
Performance of the unit is
directly related to the output of
your high-pressure washer. The sand is mixed with
the water at the sand head in a tungsten carbide
nozzle.
A vacuum is created in the sand nozzle, which
draws a sand and air mixture up the sand hose. If
the sand becomes wet or the sand nozzle becomes
plugged, the vacuum will be lost and the sand will
quit flowing. The sand probe can be poked directly
into a bag or bucket of sand to draw it up the sand
hose. Do not cover the air intake port on the top of
the sand probe or the sand flow will be disrupted.
Uncoil the sand hose completely before use to
improve the sand flow and replace the sand hose
when it becomes worn. The carbide sand-mixing
nozzle can be unscrewed and replaced when worn.
Use bagged silica sand for best results through the
sandblaster. Use 16 to 20 grit (course) sand for
rust or concrete. Use 30 grit (fine) for fine metal
surfaces or wood. Do not use wet sand or mix
different grits of sand. A sand hopper is available
for convenient sand storage. An air valve is
available for adjusting feed rate on the hopper and
should be fully open when using fine media such as
baking soda. Always use safety goggles and
protective clothing when operating the wet sand-
blaster.
TURBO NOZZLE: (please note
temperature limits below) The turbo nozzle
multiplies the power of your machine by
rotating the spray jet and making the water
impact a surface harder to give better
cleaning results.
“Turbo Laser” type nozzles cannot be used with
water over 190° or the life of the turbo nozzle will
be greatly decreased and the warranty voided. The
“Rotomax” type nozzle can be used up to 170°.
Turn off burner or reduce temperature setting
before using. Simply remove regular spray nozzle,
replace with the turbo nozzle and squeeze the
trigger on the spray gun. Do not point the turbo
nozzle upward when starting.
EXTENSION HOSES: connecting additional hose
lengths by means of twist couplers can extend the
