1.2 Normal use
The hand-held spray gun PILOT I are designed to be used exclusively for sprayable
media. Aggressive materials are not allowed to used, because the wetted parts are
not made of stainless specialty steel. Spray only materials, which not corrode the
brass-gun body.
If the material you intend to spray is not included, please contact WALTHER Spritz-
und Lackiersysteme GmbH, Wuppertal, for further information.
Please note that sprayable materials may only be applied to workpieces and/or simi-
lar objects.
The temperature of the spraying material must not exceed 43 °C. The term "normal
use” also implies that all safety warnings, operating handling details, etc., as stated in
these operating instructions are carefully read, understood and duly complied with.
This equipment complies with the explosion protection requirements of Directive 94 /
9 / EC (ATEX 100a) for the explosion group, equipment category and temperature
class indicated on the type plate. When using the equipment, the requirements speci-
fied in these Operating Instructions must be observed at all times.
The technical data indicated on the equipment rating plates and the specifications in
the chapter "Technical Data" must be complied with at all times and must not be
exceeded. An overloading of the equipment must be ruled out.
The equipment may be used in potentially explosive atmospheres only with the autho-
risation of the relevant supervisory authority.
The relevant supervisory authority or the operator of the equipment are respon-
sible for determining the explosion hazard (zone classification).
The operator must check and ensure that all technical data and the marking of the
equipment in accordance with ATEX are compliant with the necessary requirements.
The operator must provide corresponding safety measures for all applications in
which the breakdown of the equipment might lead to danger to persons.
If any irregularities are observed while the equipment is in operation, the equip-
ment must be put out of operation immediately and WALTHER PILOT must be con-
sulted.
Grounding / Equipotential Bonding
Measures must be taken to ensure that the spray gun is sufficiently grounded (eart-
hed) by means of a conductive air hose (maximum resistance 10
6
Ω ).
1.3 Improper use
The spray gun cannot be used for any application not included in the instructions.
Any other use is improper, e. g.:
• Spraying in direction of people or animals.
• Spraying liquid nitrogen.
2 Technical description
The hand-held spray gun PILOT I is a handy and extreme light-weight gun with
gravity-feed cup, developed for use in such specific areas as are ornamentation,
pattern and delicate touch-up work.
A special feature of this gun is its low input air requirement.
Open the air supply and adjust the air pressure reducing valve to the desired ato-
mizing air rate.
Pulling of the trigger (Item 23) opens the air control valve (for initial air input), follo-
wed by pull-back of the material control needle. Release of the trigger shuts the
gun in reverse order.
With the trigger pulled, the material is drawn into the spray jet column by way of
the injector effect of the atomizing air. The material output depends on the size of
the nozzle installed - and may also be controlled by way of adjusting the set-screw
(Item 18).
The spray pattern cone angle is adjusted by way of turning the air control head
(Item 1) forward or back as required (this does not apply to the flat-jet air cap).
Once the desired spray jet ratio has been obtained, use the adjusting collar (Item
2) to lock the air cap in position.
