6 Cleaning and Maintenance6.1 Safety Instructions• Prior to any servicing and repair work: Make sure that the spray gun is in unpressu-rized condition, i.e. all air and material inputs must be shut off - if not, imminent Riskof Injury .• No open fires and naked lights as well as smoking are allowed in the work area.This is a major requirement to prevent the euer present risk of fire and explosion,particularly when spraying readily flammable media such as, for example cleaningsolutions, etc.• It is important that all processing specifications and safety warnings issued by themanufacturer of cleaning media are duly complied with. Remember: Aggressive andcorrosive media represents risks and hazards to personal health.6.2 Cleaning - CompleteThe spray gun should be frequently cleaned and lubricated so as to ensure a longservice life and functional reliability. Cleaning of the gun only with cleaning solutionsrecommended by the manufacturer of the spraying material used at the time. It is im-portant to make sure that cleaning solutions do not contain any of the following con-stituents:• halogenated hydrocarbons (e.g. 1,1,1-trichloroethane; methylene chloride, etc.)• acids and acidiferous cleaning solutions• regenerated solvents (so-called cleaning dilutions)• paint removersThe above constituents cause chemical reactions with electroplated componentsresulting in corrosion damage.WALTHER PILOT is not liable for any damages resulting from improper treatement ofthe gun.Clean the spray gun• prior to each change of the spraying medium• at least once a week• as often as may be required by the spraying medium handled and the resultantdegree of fouling.CautionNever immerse the spray gun in solvent or any other cleaning solution as such mea-sure is highly likely to affect the functional reliability and efficiency of the gun.CautionDo not use any hard, pointed or sharp-edged objects when cleaning the spray gun.Any damage of the precision-made parts are likely to affect your spraying results..1. Dismantle the spray gun (see 7.2 Replacement of Material Control Nozzle andNeedle).2. Use a soft brush together with a compatible cleaning solution to clean the aircontrol head and nozzle.3. Use a suitable cloth with a compatible cleaning solution to clean the gun bodyand all remaining parts.4. Apply a thin film of the appropriate grease type/grade to the:• sealing collar of the piston• O-ring of the piston• material control needle• needle spring• inside of the gun bodyMake sure to use a non-acidic, non-resinogenic grease type/ grade and applysame with a soft brush.Assemble the spray gun in reverse order.6.3 Cleaning - RoutineThe spray gun need not necessarily be dismantled for cleaning if and when thespraying medium is changed in regular intervals or upon termination of work (de-pending, of course, an the material used).Noticelt is recommended practice to clean and lubricate the spray gun frequently inaccordance with Chapter 6.2 Cleaning - Complete, as this will greatly help towardsensuring a Jong service life and functional reliability.The following requirements must be met before the routine cleaning work can beperformed:• the material tank must be clean and then filled with a compatible cleaning soluti-on.• cleaning solution should neuer be sprayed - yet the material pressure must beavailable at the gun.The spraying system must be in Operation if a spray gun is to be cleaned.1. Take the spray gun into Operation (see 5.2 Starting / Stopping Requirements).2. Do not stop the spray gun until clear cleaning solution emerges from the nozzle.only WA XV Needle-pullWA XV -NDThe material Input can be released by hand so that the complete spraying systemmust not be taken into operation.12 13ll
