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

• 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
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 1M.
• 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 highpressure hose.

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.
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.
• 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.
• Place sprayer sucient 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

PREVENTION:
• Follow all appropriate local, state, and
national codes governing ventilation, re
prevention, and operation.
• Pulling the trigger causes a recoil force to the
hand that is holding the spray gun. The recoil
force of the spray gun is particularly powerful
when the tip has been removed and a high
pressure has been set on the airless pump.
When cleaning without a spray tip, set the
pressure control knob to the lowest pressure.
• Use only manufacturer authorized parts.
User assumes all risks and liabilities when
using parts that do not meet the minimum
specications and safety devices of the pump
manufacturer.
• ALWAYS follow the material manufacturer’s
instructions for safe handling of paint and
solvents.

Impact 740
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 highpressure steam cleaners.
1.3
ELECTROSTATIC CHARGING
FORMATION OF SPARKS OR
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 highpressure hose must be equal to or lower than 1
M.
WORK OR REPAIRS AT THE ELECTRICAL
EQUIPMENT:
These may only be carried out by a skilled
electrician. No liability is assumed for incorrect
installation.

Impact 740
2 GENERAL VIEW OF APPLICATION
2.1
The unit performance is conceived so that its use is possible on
building sites for small- to middle-area dispersion work.
EXAMPLES OF OBJECTS TO BE SPRAYED
The sprayer is able for all common varnishing jobs like doors,
door frames, balustrades, furniture, woodencladding, fences,
radiators (heating) and steel parts.
APPLICATION
2.2 COATING MATERIALS
PROCESSIBLE COATING MATERIALS
Pay attention to the Airless quality of the coating
materials to be processed.
Dilutable lacquers and paints or those containing solvents, twocomponent 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.
Attention: 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 25.000 MPa·s.
If highly viscous coating materials cannot be taken in by suction,
they must be diluted in accordance with the manufacturer’s
instructions.
TWOCOMPONENT COATING MATERIAL
The appropriate processing time must be adhered to exactly.
Within this time rinse through and clean the unit meticulously
with the appropriate cleaning materials.
COATING MATERIALS WITH SHARPEDGED ADDITIONAL
MATERIALS
These have a strong wear and tear eect on valves, highpressure hose, spray gun and tip. The durability of these parts
cane be reduced appreciably through this.

description of unit
3 DESCRIPTION OF UNIT
Impact 740
3.1
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 eect 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.
AIRLESS PROCESS
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 740 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.

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 dierent 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:
Pressure

• 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
tention
7. Replace oil cup cap.
8. Press oil button 2-5 times to prime the oiler. Press once for
every eight hours of usage to lubricate the uid section.
13
If 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.

At
i
Impact 740
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...).

If very sharp edges result or if there are streaks in
the spray jet – increase the operating pressure or
dilute the coating material.
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.

12 APPENDIX
12.1
To achieve faultless and rational working, the selection of the
tip is of the greatest importance.
In many cases the correct tip can only be determined by means
of a spraying test.
SOME RULES FOR THIS:
The spray jet must be even.
If streaks appear in the spray jet the spraying pressure is either
too low or the viscosity of the coating material to high.

12.2 SERVICING AND CLEANING OF AIRLESS
HARDMETAL TIPS
STANDARD TIPS
If a dierent tip type has been tted, then clean it according to
manufacturer’s instructions.
The tip has a bore processed with the greatest precision. Careful
handling is necessary to achieve long durability. Do not forget
the fact that the hard-metal insert is brittle! Never throw the tip
or handle with sharp metal objects.
REMEDY: Increase pressure or dilute coating material. Each
pump conveys a certain quantity in proportion to the size of
the tip:
The following principle is valid: large tip = low pressure
small tip = high pressure
There is a large range of tips with various spraying angles.
28
The following points must be observed to keep the tip
clean and ready for use:
1. Turn the relief valve handle fully counterclockwise (k
Circulation).
2. Remove the tip from the spray gun.
3. Place tip in an appropriate cleaning agent until all coating
material residue is dissolved.
4. If there is high-pressure air available, blow out tip.
5. Remove any residue by means of a sharp wooden rod
(toothpick).
6. Check the tip with the help of a magnifying glass and, if
necessary, repeat points 3 to 5.
