Everything state of the art?

Your customers expect top quality service and work. However, you

can only achieve good results if you use state-of-the-art materials and

workshop equipment, keep to procedures and carry out regular main-

tenance. Whatever this involves, stirring the mixing machine twice a day,

checking the air pressure at the spray gun or equipping the booth with

suitable lighting, you will create the best conditions for outstanding

results.

More quality. More safety.

With high grade and state of the art materials and equipment, you can

ensure trouble-free operations and eliminate expenditure on costly

repairs. This also means that you could improve safety in your workshop

and thus actively promote a healthier environment for your employees.

Everything thoroughly checked?

Carry out this workshop check and you will know precisely what to look

for, whether anything’s missing or has to be updated, and whether

procedures have to be redefined. We have prepared all the key

questions for you. All you have to do is answer with a “yes” or “no”.

Please take the necessary time and go through the questions at

your leisure with your Spies Hecker consultant.

For some questions answered with a “no”, you will undoubtedly want

to take remedial action. Please enter this on the enclosed Activity Plan.

Paint store management and paint mixing room.

Do you regularly check your stocks of materials so that you have all products available?

Do you always, rotate stock so that the older products are used up first?

Does the paint mixing room have a special floor coating or collection vessel?In these rooms it is essential to prevent solvent penetrating into the ground.

Sanding equipment.

Are special machines, e.g. orbital sanders, available for preparatory work or final sanding?Always follow the instructions of the machine and disc manufacturers.

Do you use harder back up pads for coarse and intermediate sanding and softer ones for fine and final sanding?

Are the back up pads in immaculate condition?Faulty discs can cause irregularities and scratches on the surface.

Do you use the abrasives recommended on the Technical Data Sheet?

Are the extractor ducts for sanding dust regularly cleaned?

Are the sanders oiled in accordance with the manufacturer’s instructions to prevent damage to the bearings?

Do you regularly check oil feed to the sander?

Spray guns.

Do you check the air pressure at gun inlet?Always refer to the gun manufacturer’s instructions and the paint-related

information on the Technical Data Sheets.

Before spraying, do you check your spray gun’s spray pattern?A poorly adjusted jet can cause orange peel and striping as well as colour variations?

Do you clean spray guns in the automatic gun cleaner and regularly replace the cleaning agent in order to prevent poor painting results?

Is the cleaning thinner suited to the products?Incompatibility can cause lumps in the gun

Painting and drying equipment.

Painting and drying equipment.

Have you fitted your primary and ceiling filters tightly?Contamination due to unfiltered supply air can cause paint defects.

Do you replace the primary filters at regular intervals?Check the primary filters every four months at the latest, and clean if necessary. If the

primary filter replacement indicator lights up, the primary filters should be replaced.

Do you regularly check the ceiling filters and replace them if necessary?If the ceiling filter replacement indicator lights up, the ceiling filters should be replaced.

Replacement depends on booth throughput:

• Up to five vehicles daily = once per year• More than five vehicles daily = twice per year

Do you regularly check and replace the floor filters?

If it is unused for long periods, do you clean the equipment to ensure flawless paint finishes?If the equipment is new or has been unused for long periods, run the fan

for a while before painting.

Do you exclusively use painters’ suits to prevent the development of dust and lint particles?

11

Airflow.

Do you regularly check booth overpressure?Booth overpressure should not exceed 3-5 Pa. Adjustment is possible by opening

and closing the exhaust air flaps.

The downdraught velocity (air settling rate) should be 0.2-0.3 m/s.During routine maintenance, measurement can be carried out by the

booth manufacturer or the after-sales service provider.

Is the downdraught too slow?This causes spray dust to remain in the cabin and will lead to longer flash-off times.

Is the downdraught too fast?This causes serious turbulence in the booth and the paint surface dries too fast.

Does the temperature indicated by the external thermometer concur with the drying temperature in the booth to prevent long flash-off and drying times?

Lighting.

Do you use daylight fluorescent tubes?

• Osram: L 58W/32-965

• Phillips: TC-D58W/965

Minimum lighting requirements:Colour temperature = 4,000° kelvinLuminance = 1,000 lux

Tidiness and cleanliness.

Do you keep your booth walls white?Walls contaminated with paint are not neutral in colour and impair light quality

and can thus cause paint defects.

Are roller doors and exhaust air systems cleaned regularly?

Infrared dryers.

Do you use short-wave infrared dryers for drying?Always have you’re the power supply cables and dryer checked by an authorised

electrician. If the infrared dryer is equipped with a filter system, blow the filters

regularly clean or replace them.
