The Tribo manual spray gun PEM-T3 is used for powders suitable for friction loading.
The PEM-T3 powder spray gun is used for industrial powder coating.
This spray gun can be operated with the following control units:
E Trigger
F Tribo air connection
G Powder hose connection
H Power supply
• EPG 2008 with powder injector PI-P1
• EPG-D1 with powder injector PI-F1
• Control unit Bravo with powder injector PI-FM1
The powder feed and the Tribo air supply to the spray gun are activated by pressing the
trigger.
Caution
The user must ensure, that the spray gun is only connected to Wagner equipment!
High ambient temperatures must be avoided; in particular, the hoses must not be
routed through factory areas exposed to direct sunlight!
To provide a safeguard against unintentional use of the spray gun, the control unit must
This manual contains information and hints for the service, repair and maintenance of the

1.1 Safety hints
010101_ .doc
Warning
This equipment can be dangerous if it is not operated in accordance with this
operating manual!
There might be additional regulations to be observed, put into effect by
governmental, state or other official agencies or local security (fire)
departments
!
Warning
Under no circumstance may persons with a cardiac pacemaker come close
to the area between the tip of the spray gun and the work piece to be
coated!
The following rules must be observed in order to ensure a safe and efficient use of the
equipment:
• The user has to observe particularly the safety
guidelines of the VdS, the local professional and
security institutions.
• Trained and qualified personnel may only operate the electrostatic coating equipment.
• The spray gun may only be operated in powder
coating booths or on powder coating stands that
are equipped with a ventilation system.
• The user has to make sure, that the average
powder/air concentration does not exceed 50%
of the LEL (maximum allowed concentration of
powder in air). If a reliable LEL value is not
available, the average powder/air concentration
may not exceed 10 g/m³.
• Over sprayed powder must be reliably collected.
• Adhere to the instructions given by the manufac-
turers and to the prevalent local laws on the
environment when disposing of waste coating
powder.
• The main power connection for operation of the
Wagner powder equipment must be electrically
interlocked with the exhaust system of the
powder coating booth.
• In the event of faults or defects, repair work is to
be performed at the user's discretion.
• The user must conduct periodic checks of the
powder spray equipment (at least every year)
with regard to explosion-protection.
• Repairs may only be carried out by trained technicians and may never be carried out in an
explosion hazardous area. Protective measures
against explosions must still be installed.
• The work area must have an electrostatically
conductive floor (measured in accordance with
EN 1081).
• All conductive parts in the work area must be
electrostatically grounded (work area = 1 m
around every spray location or opening in the
booth).
• All persons inside the work area must wear
electrostatically conductive footwear.
• Spray guns should be operated with bare hands!
If gloves are used they must be made of
conductive material.
• Guideline 94/9/EC: The device is suited for the
applications it was designed for, even in
explosion-hazard areas.

Safety regulations
• Wear suitable work clothing
• Use breathing protection or a vizard for work
which produces powder and when
developing solvent steams:
Avoid health dangers by inhalation and skin
contacts of solvent steams and lacquer
aerosols; Cornea injuries by splashes in the eye.
Warning
For your own safety, use only accessories and equipment listed in the
operating manual. The use of individual parts other than those
recommended in the operating manual may create a hazard to personal safety.
Use only original Wagner replacement parts!
Alteration or repair of Wagner original spare parts may cause fatal
accidents or explosions in the coating system!
010102_ .doc
• Check the equipment for damage
Before operating the system, check if slightly
damaged parts still function correctly. Check
whether the moving parts operate properly,
whether they jam and whether parts are
damaged.
Damaged parts should be repaired or
replaced by a Wagner customer service.

Preparing the spray gun
• Connect the spray gun to the Tribo current measuring or display module with the electrical
cable.
• Connect the powder hose to the spray gun and to the powder injector.
• Connect the hose for Tribo air to the spray gun and to the control unit.
2.3 Grounding
For safety reasons, the spray gunmust be properly grounded. This occurs through the
electrical cable.
Good grounding of the workpiece is also necessary for optimum powder coating.
A poorly grounded workpiece causes:
• dangerous electric charging of the workpiece
• back-spray onto spray gun and user
• uneven coating
• very bad wrap around
0203_ .doc
Warning
Sparks between workpiece and conveyor hooks (hangers) can occur if hooks or
other hanger parts are not completely cleaned!
These sparks can cause heavy radio frequency interference.

3. Working with the spray guns
3.1 Start up the spray gun
• Switch on the control unit.
• Select the type of gun Manual and charging Tribo on the control unit.
• Refer to the operating instructions of the control unit for this.
Caution
To reduce wear, the total of feed air and dosage air must range between
3.5 - 6 Nm3/h!
The total of feed air, dosage air and Tribo air should not exceed a maximum of
7.5 Nm3/h!
• Hold the manual gun in the spray booth, press the trigger and set the powder volume and
the powder speed to a test piece by adjusting the volume of feed air and dosage air.
• Only open the Tribo air until a Tribo current reading of 3 µA is attained.
Caution
The Tribo air must be reduced or shut off if the Tribo current (charging current) exceeds
μA!
3.5
The charging current depends on the type of powder used and should ideally lie between
2.5 and 3.5
3.2 Switching off the spray gun
The spray gun is switched off in different ways, depending on the type of powder injector.
Hint
The spray gun should be blown through (flushed) and cleaned from powder deposits
with every interruption of work. In this way
on again are to a great extent avoided.
The flushing procedure can be set on the control unit if the spray gun is connected to an
EPG-D1 or a Control unit Bravo in conjunction with the PI-F1 powder injector. In this case the
spray gun is blown free of powder as soon as the trigger is released.
