• Send to SATA service or sales partner: Send the spray gunto SATA service or your sales partner for checking and cleaning to ensure that all air passages are clear.
• Note: When cleaning in the washer, the spray gun should always be pressurised to prevent cleaning fluid from entering the air passages. Never soak the gun in solvent.

• Deposits in the air channels: Cleaning residue that accumulates when cleaning is not done properly can narrow the air channel cross-sections and thus cause incorrect pressure values to be displayed.
