Pre-operation
ADJUSTING FAN PATTERN
The angle of spray may be adjusted on
some lances by rotating the nozzle.
This will vary the spray pattern from
approximately a 0° narrow high impact
stream to a 60° wide fan spray. (See
Fig
)

(not applicable on some nozzles)
A narrow stream has high impact force
on the cleaning surface and results in
maximum deep cleaning in a
concentrated area. However, this
narrow high impact spray must be used
carefully as it may damage some
surfaces.

Figure 9 – Narrow high impact stream
A wide fan pattern will distribute the
impact of the water over a larger area,
resulting in excellent cleaning action
with a reduced risk of surface damage.
Large surface areas can be cleaned
more quickly using a wide fan pattern.

NOZZLE CLEANING INSTRUCTIONS
A clogged or partially clogged nozzle
can cause a significant reduction of
water and may cause the unit to pulsate
while spraying. To clean out the nozzle:
• Turn off and unplug the unit.
• Turn off the water supply and relieve
any pressure within the unit by
squeezing the trigger 2-3 times.
• Separate the lance from the gun.
• Rotate the nozzle to the narrow stream
setting. This opens up the fan blades.
• Insert the cleaning needle (8) into the
nozzle hole and move it back and forth
until the debris is dislodged (Fig 11).

• Remove additional debris by back-
flushing water through the nozzle.
To do this, place the end of a garden
hose (with water running) on the end of
the nozzle for 30-60 seconds.
HOW TO AVOID SURFACE DAMAGE
Damage to surfaces can occur when
the impact force of the water exceeds
the durability of the surface. Never use
a narrow high impact stream or a turbo/
rotary nozzle on a surface that is
susceptible to damage. Avoid spraying
windows with a narrow high impact
stream or turbo nozzle as this may
cause breakage. The surest way to
avoid damaging surfaces is to follow
these steps:
1. Before squeezing the trigger, adjust
the nozzle to a wide fan pattern.
2. Place the nozzle approximately 4-5
feet from, and angled at 45° to the
cleaning surface and begin spraying.
3. Vary the fan pattern spray angle and
the distance to the cleaning surface
until optimum cleaning efficiency is
achieved without damaging the
surface.

Detergent Applicator
Only use detergents that are specifically
made for pressure washers or you could
damage the seals/ components inside
the pressure washer.
Follow the detergent manufacturer's
directions for mixing the correct
concentrations of detergent to water
The ratio through the pressure washer
is approximately 5.4% (1 to 19).
1. Unscrew top of detergent
applicator and fill applicator with
detergent.
2. Replace top on applicator.
3. Remove lance from gun.
4. Attach detergent applicator to gun.
