Description Of Unit - WAGNER G 15 Operating Instructions Manual

1. Safety instructions for
WAGNER airless spray guns
1. Danger of injury through the spray jet.
Never direct the spray gun towards yourself, or
any other persons or animals.
The spray jet should never be allowed to
come into contact with any part of your
body (see Note a).
Take particular care when spraying with low-vis-
cosity coating materials under 10.000 mPa·s due
to increased danger of injury from the spray jet.
The very high spray pressures which occur with
airless spray guns can cause very serious inju-
ries. Coating materials can be injected into the
skin when it comes into contact with the spray
jet. In case of any skin injury by coatings or sol-
vents, consult a doctor immediately for rapid, ex-
pert treatment. Inform your doctor of the coating
or solvent which you have used.
2. Never use higher operating pressures than those
indicated on the spray gun (see Note b).
3. Recoil of spray gun.
In case of high operating pressure,
pulling the trigger can effect a
recoil force of up to 15 N.
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 high-
pressure pump. Therefore, when cleaning wi-
thout tip set the pressure control valve to the lo-
west pressure.
4. When you temporarily stop work, always lock the
spray gun using the safety catch
(2, Fig. 1). If the spray gun is locked, the
safety catch is positioned towards the rear (di-
rection of gun housing).
If the spray gun is unlocked, the safety catch po-
ints vertically downwards.
5. If the spray equipment is left unsupervised for
longer periods, or if work needs to done on the
spray equipment, then relieve the operating pres-
sure must be relieved.
6. Do not use spray guns when:
• the safety catch (2, Fig. 1) is damaged
or loose
• the trigger guard (3) is missing or loose
• the spray jet touch guard (1) is missing
or damaged

• if spraying continues when the trigger
(4) is released
• the spray gun leaks, in which case always
contact your WAGNER service point.

Note a
Spray jet touch guard
A missing or damaged spray jet touch guard can
cause serious injuries through the injection of
coatings into the skin.
Note b
Connecting spray gun to the airless high-pres-
sure pump components
It must be ensured that the airless high-pressure
pump is compatible with the max. operating pres-
sure of the spray gun. It is also necessary for all
specifications to agree in the case of the connec-
ting threads, high-pressure hoses and the compo-
nents through which the coating medium flows.
2. Proper use of spray gun G 15
The spray gun is intended for the pressurized
atomization (airless process) of liquid coating
materials.

3. Description of unit

A high-pressure pump sucks up the coating mate-
rial and feeds it to the tip in the spray gun under
pressure. The coating material is atomized due to
the high pressure forcing it through the tip.
The spray gun corresponds with Ex II 2G X and is,
in accordance with Directive 94/9/EEC (Atex
100a), suitable for use in explosion-hazardous are-
as of type Zone 1. Under certain circumstances,
the unit itself may cause the Zone 1 condition to
be in effect.
