hAZArD: INjecTIoN INjury
Attention: Danger of injury by
injection! A high pressure stream
produced by this equipment can
pierce the skin and underlying tissues,
leading to serious injury and possible
amputation.
Do not treat a spraying injury as a
harmless cut. In case of injury to the
skin through coating materials or
solvents,consultadoctor immediately
for quick and expert treatment. Inform
the doctor about the coating material
or solvent used.
preveNTIoN:
• NEVER aim the gun at any part of the body.
• NEVER allow any part of the body to touch
the uid stream. DO NOT allow body to touch
a leak in the uid hose.
• NEVER put your hand in front of the gun.
Gloves will not provide protection against an
injection injury.
• ALWAYS lock the gun trigger, shut the uid
pump o and release all pressure before
servicing, cleaning the tip guard, changing
tips, or leaving unattended. Pressure will not
be released by turning o the engine. The
PRIME/SPRAY valve or pressure bleed valve
must be turned to their appropriate positions
to relieve system pressure.
• ALWAYS keep tip guard in place while
spraying. The tip guard provides some
protection but is mainly a warning device.
• ALWAYS remove the spray tip before ushing
or cleaning the system.
• NEVER use a spray gun without a working
trigger lock and trigger guard in place.

5
safety precautions
Impact 440
• All accessories must be rated at or above
the maximum operating pressure range of
the sprayer. This includes spray tips, guns,
extensions, and hose.
hAZArD: hIgh preSSure
hoSe
The paint hose can develop leaks from
wear, kinking and abuse. A leak can
inject material into the skin. Inspect
the hose before each use.
preveNTIoN:
• Avoid sharp bending or kinking of the high-
pressure hose. The smallest bending radius
amounts to about 20 cm.
• Do not drive over the high-pressure hose.
Protect against sharp objects and edges.
• Replace any damaged high-pressure hose
immediately.
• Never repair defective high-pressure hoses
yourself!
• Electrostatic charging of spray guns and the
high-pressure hose is discharged through
the high-pressure hose. For this reason the
electric resistance between the connections
of the high-pressure hose must be equal to or
lower than 1MΩ.
• For reasons of function, safety and durability
use only original Titan high-pressure hoses.
• Before each use, check all hoses for cuts,
leaks, abrasion or bulging of cover. Check
for damage or movement of couplings.
Immediately replace the hose if any of
these conditions exist. Never repair a paint
hose. Replace it with another earthed high-
pressure hose.
• Make sure power cord, air hose and spray
hoses are routed in such a manner to minimize
slip, trip and fall hazard.

safety precautions Impact 440
hAZArD: exploSIoN or fIre
Flammable vapors, such as solvent
and paint vapors, in work area can
ignite or explode.
preveNTIoN:
• Do not use materials with a ashpoint below
38° C (100° F). Flashpoint is the temperature
at which a uid can produce enough vapors
to ignite.
• Do not use the unit in work places which
are covered by the explosion protection
regulations.
• Provide extensive exhaust and fresh air
introduction to keep the air within the spray
area free from accumulation of ammable
vapors.
• Avoid all ignition sources such as static
electricity sparks, electrical appliances,
ames, pilot lights, hot objects, and sparks
from connecting and disconnecting power
cords or working light switches.
• Do not smoke in spray area.
• Place sprayer sucient distance from the
spray object in a well ventilated area (add
more hose if necessary). Flammable vapors
are often heavier than air. Floor area must
be extremely well ventilated. The pump
contains arcing parts that emit sparks and
can ignite vapors.
• The equipment and objects in and around
the spray area must be properly grounded to
prevent static sparks.
• Use only conductive or earthed high pressure
uid hose. Gun must be earthed through
hose connections.
• Power cord must be connected to a grounded
circuit (electric units only).
• Always ush unit into separate metal
container, at low pump pressure, with spray
tip removed. Hold gun rmly against side of
container to ground container and prevent
static sparks.
• Follow material and solvent manufacturer’s
warnings and instructions. Be familiar with
the coating material’s MSDS sheet and
technical information to ensure safe use.
• Use lowest possible pressure to ush
equipment.
• When cleaning the unit with solvents, the
solvent should never be sprayed or pumped
back into a container with a small opening
(bunghole). An explosive gas/air mixture can
arise. The container must be earthed.
• Do not use a paint or solvent containing
halogenated hydrocarbons. Such as chlorine,
bleach, mildewcide, methylene chloride and
trichloroethane. They are not compatible
with aluminum. Contact the coating
supplier about compatibility of material with
aluminum.

safety precautions Impact 440
1.2 elecTrIc SAfeTy
Electric models must be earthed. In the event
of an electrical short circuit, earthing reduces
the risk of electric shock by providing an escape
wire for the electric current. This product is
equipped with a cord having an earthing wire
with an appropriate earthing plug. Connection
to the mains only through a special feed point,
e.g. through an error protection insallation with
INF < 30 mA.
DANGER — Work or repairs at the
electrical equipment may only be
carried out by a skilled electrician.
No liability is assumed for incorrect
installation. Switch the unit o.
Before all repair work, unplug the
power plug from the outlet.
Danger of short-circuits caused by water
ingressing into the electrical equipment. Never
spray down the unit with high-pressure or high-
pressure steam cleaners.
Work or repAIrS AT The elecTrIcAl
equIpmeNT:
These may only be carried out by a skilled
electrician. No liability is assumed for incorrect
installation.
1.3 elecTroSTATIc chArgINg
(formATIoN of SpArkSor
flAmeS)
Electrostatic charging of the unit may
occur during spraying due to the ow
speed of the coating material. These
can cause sparks and ames upon
discharge. The unit must therefore
always be earthed via the electrical
system. The unit must be connected
to an appropriately-grounded safety
outlet.
An electrostatic charging of spray guns and the
high-pressure hose is discharged through the
high-pressure hose. For this reason the electric
resistance between the connections of the high-
pressure hose must be equal to or lower than 1
MΩ.

proceSSIBle coATINg mATerIAlS
iPay attention to the Airless quality of the coating
materials to be processed.
Dilutable lacquers and paints or those containing solvents, two-
component coating materials, dispersions, latex paints, release
agents, oils, undercoats, primers, and llers.
No other materials should be used for spraying without Titan’s
approval.
fIlTerINg
Despite suction lter and insertion lter in the spray gun,
ltering of the coating material is generally advisable.
Stir coating material before commencement of work.
iAttention: Make sure, when stirring up with
motor-driven agitators that no air bubbles are
stirred in. Air bubbles disturb when spraying and
can, in fact, lead to interruption of operation.
vIScoSITy
With this unit it is possible to process highly viscous coating
materials of up to around 20.000 MPa·s.
If highly viscous coating materials cannot be taken in by suction,
they must be diluted in accordance with the manufacturer’s
instructions.
TWo-compoNeNT coATINg mATerIAl

description of unit Impact 440
3 DeScrIpTIoN of uNIT
3.1 AIrleSS proceSS
The main areas of application are thick layers of highly viscous
coating material for large areas and a high consumption of
material.
A piston pump takes in the coating material by suction and
conveys it to the tip. Pressed through the tip at a pressure of
up to a maximum of 221 bar (22.1 MPa), the coating material
is atomised. This high pressure has the eect of micro ne
atomisation of the coating material.
As no air is used in this process, it is described as an AIRLESS
process.
This method of spraying has the advantages of nest
atomisation, cloudless operation and a smooth, bubble-free
surface. As well as these, the advantages of the speed of work
and convenience must be mentioned.
3.2 fuNcTIoNINg of The uNIT
In the following there is a short description of the technical
construction for better understanding of the function.
Titan Impact 440 units are electrically driven high-pressure
spraying units.
A gear unit transfers the driving force to a crankshaft. The
crankshaft moves the pistons of the material feed pump up and
down.
The inlet valve is opened automatically by the upwards
movement of the piston. The outlet valve is opened when the
piston moves downward.
The coating material ows under high pressure through the
high-pressure hose to the spray gun. When the coating material
exits from the tip it atomizes.
The pressure control knob controls the volume and the
operating pressure of the coating material.

4.2 CONTROL PANEL INDICATORS
The following is a description of the control panel indicators.
Pressure
Indicator
Service
Indicator
SERVICE INDICATOR
The Service indicator is on when the motor is commanded to
run. This indicator is used by service centers to troubleshoot
motor problems.
PRESSURE INDICATOR
The pressure indicator shows the current operating pressure of
the sprayer. It has three dierent indications: blinking yellow,
solid yellow, and solid green.
Blinking Yellow
When the pressure indicator is blinking yellow, the sprayer is
operating between 0 and 1.4 MPa (14 bar). A blinking yellow
pressure indicator means:
• The sprayer is plugged in and turned “ON”
• The sprayer is at priming pressure (little or no pressure)
• It is safe to move the relief valve between positions
• It is safe to change or replace the spray tip
iIf the pressure indicator begins blinking yellow
when the pressure control knob is set at a higher
pressure and the relief valve is in the SPRAY
position, either the spray tip is worn or the
sprayer is in need of service/repair.
Solid Yellow
When the pressure indicator is solid yellow, the sprayer is
operating between 1.4 MPa (14 bar) and 12 MPa (120 bar). A
solid yellow pressure indicator means:
• The sprayer is at the proper pressure setting for spraying
stain, lacquer, varnish, and multi-colors
Solid Green
When the pressure indicator is solid green, the sprayer is
operating between 12 MPa (120 bar) and 23 MPa (230 bar). A
solid green pressure indicator means:
• The sprayer is at the proper pressure setting for spraying
oil-based and latex house paints
• The sprayer is operating at peak performance at a high
pressure setting
• If the pressure indicator goes to solid yellow when the
pressure is set so that it starts at solid green, it indicates
one of the following:
a. Tip Wear Indicator — when spraying with latex or at high
pressure the solid yellow appears. This means the tip is
worn and needs to be replaced.
b. Tip Too Large — when a tip that is too large for the sprayer
is put in the gun, the pressure indicator will turn from solid
green to solid yellow.
c. Fluid Section Wear — if a solid yellow pressure indicator
appears when using a new tip and the pressure is set at
maximum, service may be required (worn packings, worn
piston, stuck valve, etc...).

the tip is completely turned to either the spray
or the unclog position. ALWAYS engage the
gun trigger lock before removing, replacing or
cleaning tip.
A) The key to a good paint job is an even coating over the
entire surface. Keep your arm moving at a constant
speed and keep the spray gun at a constant distance from
the surface. The best spraying distance is 10-12 inches
(25 to 30 cm) between the spray tip and the surface.
25 - 30 cm

B) Keep the spray gun at right angles to the surface. This
means moving your entire arm back and forth rather than
just exing your wrist.
Keep the spray gun perpendicular to the surface,
otherwise one end of the pattern will be thicker than the
other.

handling the high -pressure hose / interruption of work Impact 440
6 hANDlINg The hIgh-preSSure hoSe
iThe unit is equipped with a high-pressure hose
specially suited for piston pumps.
Danger of injury through leaking high-pressure
hose. Replace any damaged high-pressure hose
immediately.
Never repair defective high-pressure hoses
yourself!
The high-pressure hose is to be handled with care. Avoid sharp
bends and folds: the smallest bending radius is about 8” (20 cm).
Do not drive over the high-pressure hose. Protect against sharp
objects and edges.
Never pull on the high-pressure hose to move the device.
Make sure that the high-pressure hose cannot twist. This can
be avoided by using a Titan spray gun with a swivel joint and a
hose system.
iWhen using the high-pressure hose while
working on scaolding, it is best to always guide
the hose along the outside of the scaolding.
iThe risk of damage rises with the age of the
high-pressure hose. Titan recommends replacing
high-pressure hoses after 6 years.
iUse only Titan original-high-pressure hoses
in order to ensure functionality, safety and
durability.
