BASIC
ELEMENTS
OF
A PRESSURE
WASHER
•
High
Pressure
Pump:
Increases
the
pressure
of
the
water
supply.
•
Engine:
Drives
the
high
pressure
pump.
•
High
Pressure
Hose:
Carries
the
pressurised
water
from
the
pump
to
the
gun
and
spray
wand.
•
Spray
Gun:
Connects
with
spray
wand
to
control
water
flow
rate,
direction,
and
pressure.
•
Quick
Connect
Spray
Wand:
Allows
the
user
to
quickly
change
high-pressure
nozzles.
See
How
To
Use
Spray
Lance
instructions
in
this
section.
•
Chemical
Hose
(not
shown):
Feeds
cleaning
agents
into
the
pump
to
mix
with
the
water.
See
How
To
Apply
Chemicals/Cleaning
Solvents
instructions
in
this
section.
6.5
PRESSURE
WASHER
TERMINOLOGY
•
PSI:
Pounds
per
Square
Inch.
The
unit
of
measure
for
water
pressure.
Also
used
for
air
pressure,
hydraulic
pressure
etc.
•
L/M:
Liters
Per
Minute.
The
unit
of
measure
for
the
flow
rate
of
water.
•
Bypass
Mode:
Allows
water
to
re-circulate
within
pump
when
the
gun
trigger
is
not
pulled.
CAUTION
Allowing
the
unit
to
run
for
more
than
one
minute
without
the
gun
trigger
pulled
could
cause
overheating
and
damage
to
the
pump.
6.6
PRESSURE
WASHER
OPERATING
FEATURES
PRESSURE
ADJUSTMENTS
The
pressure
setting
is
preset
at
the
factory
to
achieve
optimum
pressure
and
cleaning.
If
you
need
to
lower
the
pressure,
it
can
be
accomplished
by
these
methods.
1.
Back
away
from
the
surface
to
be
cleaned.
The
further
away
you
are,
the
less
the
pressure
will
be
on
the
surface
to
be
cleaned.
2.
Change
to
the
40°
nozzle
-
(white)
this
nozzle
delivers
a
less
powerful
stream
of
water
and
a
wider
spray
pattern
(Fig
6-6A).
3.
Reduce
the
speed
of
the
gasoline
engine
(RPM).
Slow
the
engine
down
and
the
water
pressure
will
go
down
with
it.
19
CAUTION
DO
NOT attempt
to
increase
pump
pressure.
A higher
pressure
setting
than
the
factory
set
pressure
may
damage
pump.
THERMAL RELIEF
VALVE
When
the
temperature
inside
the
pump
rises
too
high
the
valve
will
open
and
release
a
gush
of
water
in
an
effort
to
lower
the
temperature
inside
the
pump.
The
valve
will
then
close
(Fig.
6-6B).

Litres
CAUTION
Used
motor
oil
may

with
the
skin
for
prolonged
periods.
Although
this
is
unlikely
unless
