Normal use

The manual spray guns of the series PILOT Maxi / MP / HVLP are designed to be used
exclusively for sprayable media, such as:
• paints and lacquers
• greases, oils and corrosion preventives
• ceramic glazes
• stains
• adhesives (only PILOT Maxi-K-versions)
Since all wetted parts are made of stainless specialty steel, the spray guns can also be
used for spraying aqueous materials.
If the material you intend to spray is not included in the above list, please contact
WALTHER Spritz- und Lackiersysteme GmbH, Wuppertal, for further information.
Please note that sprayable materials may only be applied to workpieces and/or similar
objects. The spray gun models PILOT Maxi-K and PILOT Maxi-HVLP-K are specially
designed for use with adhesive coatings. The model PILOT Maxi-K is made for solvent
adhesive and the model PILOT Maxi-HVLP-K is made for dispersion coating. All
media-supplying parts are made of stainless special steel.
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
2014/34/EU (ATEX) for the explosion group, equipment category and temperature class
indicated on the type plate. When using the equipment, the requirements specified 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 authorisation of the relevant superviso-
ry 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 equipment
must be put out of operation immediately and WALTHER Spritz- und Lackiersysteme

Technical description

Models PILOT Maxi, PILOT Maxi-MP, PILOT Maxi-HVLP
PILOT Maxi / Maxi-K*: Manual spray gun for conventional atomisation
Model versions: • with gravity-feed cup* • with suction cup • with material connection*
PILOT Maxi-MP: Manual spray gun for medium pressure
Model versions: • with gravity-feed cup • with suspended pressure cup • with material
connection. The spraying pressure is 1.2 to 1.4 bar with an input pressure of 3.0 to 3.3
bar.
PILOT Maxi HVLP / Maxi-HVLP-K: Manual spray gun for low pressure
Model versions: • with gravity-feed cup • with suspended pressure cup • with material
connection. The spraying pressure is 0.7 bar with an input pressure of 3.5 bar.
For model versions with suspended pressure cup the material pressure shall not
exceed 3 bar.
When operating the trigger, the air valve (preliminary air) is opened first and then the
material needle (pos. 16) is pulled back. This allows the spraying material to flow
through the nozzle. Closing is performed in reverse order. The material flow rate is
Ω).
