OPERATING MANUAL
4.2 SAFETY INSTRUCTIONS FOR STAFF
Always follow the information in these instructions, particularly the general safety instructions
and the warning instructions.
Always follow local regulations concerning occupational safety and accident prevention.
4.2.1 SAFE HANDLING OF WAGNER SPRAY DEVICES
The spray jet is under pressure and can cause dangerous injuries.
Avoid injection of paint or cleaning agents:
Never point the spray gun at people.
Never reach into the spray jet.
Before all work on the device, in the event of work interruptions and functional faults:
– Switch off the energy/compressed air supply.
– Relieve the pressure from the spray gun and device.
– Secure the spray gun against actuation.
– In the event of functional faults: remedy the fault as described in the "Troubleshooting"
chapter.
The liquid ejection devices are to be checked for safe working conditions by an expert
(e.g. Wagner Service Technician) as often as necessary or at least every 12 months,
in accordance with the guidelines for liquid emitters (ZH 1/406 and BGR 500 Part 2
Chapter 2.36).
– For devices that have been shut down, the inspection can be postponed until the next
commissioning.
Carry out the work steps as described in the "Pressure Relief/Work Interruptions" chapter:
– if pressure relief is required.
– if the spraying work is interrupted or stopped.
– before the device is cleaned on the outside, checked, or serviced.
– before the spray nozzle is installed or cleaned.
In the event of skin injuries caused by paint or cleaning agents:
Note down the paint or cleaning agent that you have been using.
Consult a doctor immediately.
Avoid danger of injury through recoil forces:
Ensure that you have firm footing when operating the spray gun.
Only hold the spray gun briefly in a position.

VERSION 10/2013
OPERATING MANUAL
4.2.2 GROUNDING THE DEVICE
In order to avoid electrostatic charging of the device, the device must be grounded.
Friction, flowing liquids, and air or electrostatic coating processes create charges. Flames or
sparks can form during discharge.
Ensure that the device is grounded for every spraying operation.
Ground the work pieces to be coated.
Ensure that all persons inside the working area are grounded, e.g. that they are wearing
static dissipative shoes.
Wear dissipative gloves when spraying.The grounding takes place via the spray gun handle.
4.2.3 PRODUCT HOSES
Ensure that the hose material is chemically resistant to the sprayed products.
Ensure that the product hose is suitable for the pressure generated in the device.
Ensure that the following information can be seen on the high-pressure hose:
– Manufacturer
– Permissible operating overpressure
– Date of manufacture
Make sure that the hoses are laid only in suitable places. In no case, should hoses be laid
in the following places:
– in high-traffic areas,
– on sharp edges,
– on moving parts, or
– on hot surfaces
Make sure that the hoses are never used to pull or move the device.
The electrical resistance of the complete high-pressure hose must be less than 1 Mohm.
Several liquids have a high expansion coefficient. In some cases their volume can rise with
consequent damage to pipes, fittings, etc. and cause fluid leakage.
When the pump sucks liquid from a closed tank, ensure that air or suitable gas can enter
the tank to avoid a vacuum being generated in the tank itself. Thus a negative pressure is
avoided. The vacuum could implode the tank (squeeze) and can cause it to break. The tank
would leak and the liquid would flow out.
The pressure created by the pump is a multiplication of the inlet air pressure.

4.2.4 CLEANING
De-energize the device electrically.
Disconnect the pneumatic supply line.
Relieve the pressure from the device.
Ensure that the flash point of the cleaning agent is at least 5 K above the ambient temperature.
To clean, use cloths and brushes moistened with solvent. Never use hard objects or spray
on cleaning agents with a gun.
Preferably, non-combustible cleaning agents should be used.
An explosive gas/air mixture forms in closed tanks.
When cleaning devices with solvents, never spray into a closed tank.
Only use electrically conductive tanks for cleaning liquids.
The tanks must be grounded.
4.2.5 HANDLING HAZARDOUS LIQUIDS, LACQUERS AND PAINTS
When preparing or working with lacquer and when cleaning the device, follow the
working instructions of the manufacturer of the lacquers, solvents and cleaning agents
being used.
Take the specified protective measures; in particular, make sure that you wear safety
goggles, protective clothing, and gloves, as well as skin protection cream if necessary.
Use a mask or a breathing apparatus if necessary.
For sufficient health and environmental safety: operate the device in a spray booth or
on a spraying wall with the ventilation (extraction) switched on.
Wear suitable protective clothing when working with hot products.
4.2.6 TOUCHING HOT SURFACES
Only touch hot surfaces if you are wearing protective gloves.
When operating the device with a coating product with a temperature of > 43 °C; 109.4 °F:
- Identify the device with a warning label "Warning - hot surface".
Order No.

4.3 USE IN AREAS SUBJECT TO EXPLOSION HAZARDS
The pneumatic pump may be used in potentially explosive areas. The following safety
regulations must be observed and followed.
4.3.1 SAFETY REGULATIONS
Safe handling of WAGNER spray devices
Mechanical sparks can form if the device comes into contact with metal.
In an explosive atmosphere:
Do not knock or push the device against steel or rusty iron.
Do not drop the device.
Only use tools that are made of a permitted material.
Ignition temperature of the pumped product
Check that the ignition temperature of the pumped product is higher than the max.
allowable surface temperature.
Medium supporting atomizing
To atomize the product, use only weakly oxidizing gases, e.g. air.
Surface spraying, electrostatics
Do not spray device parts using electrostatic equipment.
Cleaning
If there are deposits on the surfaces, the device may form electrostatic charges. Flames or
sparks can form during discharge.
Remove deposits from the surfaces to maintain conductivity.
Only use a damp cloth to clean the device.

4.3.2 OPERATION WITHOUT FLUID
Avoid running the pump so that it sucks in air (without fluid inside). The air, combined with
the vapor of flammable fluids, can generate internal areas with an explosion hazard.
Periodically check that the pump is working smoothly, paying special attention to the
presence of air in the pumped fluid, which may be caused by damaged packings.
Avoid operating the pump with damaged packings.
Ensure that the separating agent tank is filled with sufficient separating agent.

General information
The double diaphragm pump is driven with compressed air. This compressed air moves the air piston in the air
motor (4), and consequently the piston rod in the pressure stage (9), up and down. At the end of each stroke
the compressed air is redirected by a reversing valve and the control piston. The up-and-down movement of
the 2 diaphragms within the fluid section is produced by hydraulic oil, which is moved by the piston in the
pressure stage. With every stroke of the piston rod, working material is sucked in and delivered to the spray
gun at the same time.
Air motor (4)
The air motor with its pneumatic reverse (1) does not require pneumatic oil.
The compressed air is fed to the motor via the air pressure regulator (2) and the ball valve (3).
The air motor is fitted with a safety valve. The safety valve has been set and sealed at the factory. In case
of pressures over and above the permissible operating pressure, the valve, which is held with a spring,
automatically opens and releases the excess pressure.

WARNING
Overpressure!
Risk of injury from bursting components.
Never change the safety valve setting.
Fluid section (9)
The fluid section has been designed as a double diaphragm pump with exchangeable
inlet and outlet valves. Change between "spraying mode" and "circulation mode" using
the relief valve (7).
Positioning
The Cobra pump may only be operated in a horizontal
or vertical position as shown in the diagrams. Overhead
operation is not permitted.
