This symbol indicates a potential hazard to you or to the
equipment. Important information that tells how to prevent
damage to the equipment or how to avoid causes of minor
injuries will follow.

Attention! Danger of injury by injection!
In case of injury to skin caused by coating materials or
solvents consult a doctor immediately. Inform the doctor of the
type of coating material or cleaning agent with which the injury
was caused.
The operating instructions state that the following points
must always be observed before starting up:
1. Faulty units should not be used.
2. Secure spray gun using the safety catch on the trigger.
3. Ensure that the unit is properly earthed.
4. Check the permissible operating pressures.
5. Check all connections for leaks.
The instructions regarding regular cleaning and
maintenance of the unit must be strictly observed.
Before any work is done on the unit or for every break in
work the following rules must be observed:
1. Release the pressure from the spray gun and hose.
2. Secure the spray gun using the safety catch on the
trigger.
3. Turn off the motor.
Be safety-conscious!
All local regulations in force must be observed.
In order to ensure safe operation of the airless systems
the safety regulations listed below must be followed:
1. In order to avoid dangers, read the operating instructions
carefully and follow the instructions laid down in them.
2. Do not use materials with a flash point below 21ºC (70ºF).
3. The use of this unit is prohibited in workshops which are
covered under the explosion prevention regulations.
4. Never spray near sources of ignition; e.g. open flames,
cigarettes — also cigars and pipes are sources of ignition
— sparks, hot wires and hot surfaces, etc.
5. Attention! Danger of injury by injection!
Never point the spray gun at yourself or anyone else.
Never put your fingers or hands into the spray jet. The
very high spraying pressures can cause very serious
injuries. Never use the spray gun without the safety guard.
When installing and removing the tip and during breaks in
work the spray gun must always be secured, so that it
cannot be activated.
6. Wear respiratory equipment when spraying. The operator
must be provided with a protective mask.
In order to prevent work related illness, the manufacturer's
regulations for the materials, solvents, and cleaning
agents used must be observed when preparing, working
with and cleaning the unit. Protective clothing, gloves and,
in certain cases, protective skin cream are necessary to
protect the skin.
7. The spray gun and high pressure hose between the unit
and spray gun must be of a sufficient standard for the
pressure produced in the unit.
The permissible operating pressure for the high-pressure
hose, the manufacturer and date of manufacture must be
indicated by a permanent identification marking on the
hose. Furthermore, it must be constructed so that the
electrical resistance between the connections to the unit
and the spray gun is equal to or less than one megohm.
8. Under certain conditions the flow speed can cause an
electrostatic charge on the unit. This could cause sparks
or flames on discharging. It is, therefore, important that
the unit is always earthed over the electrical installation.
The contact should be made using a shockproof socket
earthed in accordance with the regulations.
