Your new UltraTM 333 Sprayer
functions
and operates
differently
than other airless paint sprayers.
This section
will help you become
familiar
with the sprayer
before
operating
it.
Pressure Control
The pressure control
includes
an ON/OFF
switch for the
sprayer, the pressure adjusting
control
knob, a pressure
sensing
device,
and a current
overload
circuit
breaker
with a manual reset button.
Its function
is to control
the
motor
speed
so that
the sprayer
maintains
constant
fluid pressure at the pump outlet.
Motor
The
DC motor
has sealed
bearings
and replaceable
motor brushes.
Its function
is to drive the displacement
pump
at the
rate needed
to supply
sufficient
paint
volume
at the selected
pressure.
Working
together,
the
pressure
control
and
motor
cause the pump
to cycle
whenever
there
is fluid
or
pressure demand.
When the pump is cycling,
the motor
sounds
like an automobile
starter
cranking.
When
the
pump
is not cycling,
the motor
hums,
hums intermit-
tently,
or appears to have shut itself off. However,
there
will
still
be power
to the
sprayer
and
it will
stay
pressurized
and ready to use unless you manually
shut it
off and relieve pressure.
Because
the motor
is DC, it is less sensitive
to low
voltage
or voltage
fluctuations
than an AC motor,
and
an extension
cord of up to 150 feet (45 m) can be used.
Drive Assembly
The sealed drive assembly
transfers
power from the DC
motor to the displacement
pump.

Displacement
Pump
The positive
displacement,
volume-balanced
pump pro-
vides
equal fluid
delivery
on both
the up and down
pump strokes.
The pump
has a wet-cup
which,
when
filled
with
Grace
Throat
Seal
Liquid,
helps
prevent
damage
to the throat
packings
and piston
rod.
Fluid Filter
The fluid filter provides
the final paint straining
to help
avoid clogs in the hose and spray tip. The filter includes
a reusable
element
and a drain valve for relieving
fluid
pressure
when shutting
off the sprayer.
Hoses
The grounded,
nylon spray hoses have spring guards on
both ends. The 50 foot (15.2 m) hose has a l/4
in. ID.
The 3 foot (0.9 m), 3/16
in. ID whip hose allows flexi-
ble gun movement.
The nylon hose material
acts as a
pulsation
dampener
to absorb
pressure fluctuations.
Spray Gun & Reverse-A-Clean
Ill Spray Tip
Both the "Contractor"
and "Flex"
spray guns include a
trigger
safety
which
prevents
accidental
triggering
when it is engaged
(see the WARNING
on page 3):The
Reverse-A-Clean
III
spray
tip uses high pressure fluid to
remove
clogs
from
the spray tip without
removing
it
from the gun. It includes
a safety tip guard which
helps
reduce the risk of injection
injury.
