1.2 APPLICATION
The Spray-gun washer was designed and built exclusively to wash spray-guns or small-sized pieces, using clean water or special
water-based solvents. The Spray-gun washer can be used only to wash parts that have been soiled with paint. Pieces must be
made of metal, preferably steel or anti-static material, and must have a weight that does not exceed 10 kg. Ensure that the pH of
the water-based solvent ranges between 6.5 and 12 when used instead of water to wash parts. The fluid solvent mixture should not
contain inflammable components; if such components are present, the concentration must not exceed 8%.
PROHIBITED USES OF THE SPRAY-GUN WASHER:
All washing operations of objects or products that are not included in this manual, or of objects approved (spray-gun and small com-
ponents) but with solvents with specifications other than those indicated in this manual, are expressly forbidden:
WARNING
The Spray-gun washer must be used exclusively for the purpose for which it was designed and built. All
other uses not covered by this manual are to be considered inappropriate and are strictly forbidden.
ANEST IWATA EUROPE declines any and all responsibility for damage to persons, animals and property
deriving from improper use of the Spray-gun washer and/or from failure to observe the instructions in
this manual.
The Spray-gun washer has been designed and built by ANEST IWATA EUROPE in order to guarantee a high level of protection,
efficient operations and conformity with the working parameters provided for devices group II, category 2 in explosive atmosphe-
res caused by gas, vapour or mist in compliance with Directive 94/9/CE (ATEX).
The Spray-gun washer is fitted with protection systems that guarantee the required level of protection also when recurring trou-
bles or working faults of the appliance itself are expected.
Thanks to such design and manufacture, the Spray-gun washer can be used in environments where the atmosphere is potential-
ly explosive which are classified according to the following risk areas (Directive 1999/92/CE).
•ZONE 1 : Area in which - during normal working activities - an occasional explosive atmosphere is to be expected which consi-
sts of a composition of air and flammable substances in form of gases, vapours or mists.
The device can always be used in areas where there is a lower risk of explosion, such as in zone 2.
Since the Spray-gun washer was built to wash spray-guns using clean water or water-based solvents devoid of inflammable com-
ponents, there are no restrictions with respect to the installation of other machines near the Spray-gun washer.

(pos. 36 fig.1) rinse the washing tank (pos. 2 fig 1).
•After filtering the water, pour the sludge from the filter in an outside container and deliver to a specialised waste treatment com-
pany. The water in container (W53) can be re-used.
•Before starting again with the Spray-gun washer, pour with the brush (pos. 36 fig. 1) approximately 10 litres of water in the
wash tank (pos. 2 fig 1) and approximately 30 litres in container (pos. W53 fig.1).
•Replace the grill (pos. 6G fig 1).

7.1 OPERATION
The compressed air inlet passes through the filter (1) and feeds the bottle neck (2), the air gun (3), the flow regulator (4) and the
ball valves (9) and (11). Valve (9) supplies the nebulizer (10). Valve (11) supplies the small pump (12). The flow regulator (4) sup-
plies the distributor (5). The ball valve (15) controls the water supply of the company, which is regulated by the valve (16) and is con-
nected to the brush (17). Valve (7) drains the dirty water from tank (6) to the recovered water tank (8).

8. MAINTENANCE AND PERIODICAL CHECKS
The following ordinary maintenance procedures must be performed. Extraordinary maintenance (repair of basic machine compo-
nents) must be carried out by qualified personnel only, according to the listed instructions in this manual.
•Disconnect the compressed air supply before carrying out any repair or maintenance work.
•Check periodically that safety devices are in good repair and work satisfactorily.
•Never remove or tamper with any safety devices.
•The pictograms (labels) applied to the Spray-gun washer provide suitable indications for the avoidance of accidents. These
pictograms must be kept clean and replaced immediately if even partly missing or damaged. The use of the Spray-gun washer
is absolutely prohibited if even one only of the diagrams is missing from the point where it was placed by the manufacturer.
•During repair and maintenance use only original spare parts.
•Check that the machine is always connected with the earthing cable.
•Remove any encrustation from the grill (pos.6G fig.1).
•Check and clean periodically the air inlet filter, which is inside the fitting (pos.12 fig.1), if possible without removing the fitting
itself.
•Check that the water level in the wash tank (pos.2 fig.1) is not over the grill placed above (pos.6G fig.1).
•Check that the hoses (pos. 23 and 24 fig.1) are not bent, worn or broken and that they are well inserted in tank (W53 fig. 1).
•Clean and rinse the wash tank, when removing the dirty water (pos.2 fig.1).
•Replace the pre-filter bag (pos.W50 fig.1) after each filtration.
•Clean or replace the filter bag (W51).
