thehumiditymustdecreaseproportionallyinordertoensureoperationalreadiness(e.g.,at35°C[95°F]=65%humidity;at40°C[104°F]=50%humidity).Theunitmaynotbeoperatedattemperaturesabove40°C[104°F].

2.4 Hazards and warnings ► If the unit is not used according to the instructions for use, then protection can no longer be guaranteed. ► The unit may only be used together with a mains cable with a country specific plug system. If a plug ex-change is necessary, this may only be undertaken by a skilled electrician. ► The mains plug must be easy to access. ► Check connection cables (e.g. power cable), tubes and housing (e.g. operating key pad) regularly for dam-age (e.g. kinks, cracks, porosity) or aging. Appliances with damaged connection cables, tubes or housing parts or other defects must no longer be operated! Remove the power cable and secure against being switched on again! ► Risk of Injury! If unauthorised attachments are used, there is a danger of injury. Only original Renfert fittings and acces-sories may be used. ► Please observe the accident prevention regulations provided by the „employer‘s liability insurance associ-ation“! ► Always disconnect the unit from the compressed air and power sources prior to beginning any mainte-nance work. ► When working on the tank (filling up, cleaning, maintenance) wear protective glasses for protecting your eyes. ► Any residue of abrasive material on the gasket may lead to leakage and early wear of the gasket. After filling up clean the thread and the gasket and close the lid properly. ► DO NOT use solvent-containing cleaning agents or disinfectants. ► Solvents and tensides can create micro-cracking in the plastic (danger of explosion!). Clean the tank and the lid only with a dry cloth. Do not write or stick something on the tanks. ► Do not unscrew the tank lid as long as the pressure had not been released ► Check the tanks and the lids regularly on damages and replace them in case of doubt. ► Check the tank cover for correct seating prior to beginning operation. Covers that are not securely closed can suddenly be blown off as the tank pressure increases. The resulting flying parts and abrasive repre-sent a serious hazard. ► Never operate the blasting units without suitable dust extraction and appropriate protective gear, as this could result in health hazards. The type of dust extraction should be selected on the basis of the dust be-ing generated. Follow here absolutely EN 60335-2-69 appendix AA or ask the appropriate authorities. ► Improper use can result in the risk of eye or skin injuries. ► Never direct the blasting material towards eyes or unprotected areas of skin! ► Never work with the view screen open! ► Caution: Failure to wear proper eye protection can result in eye injury due to particles suspended in the air. Always wear proper eye protection to protect your vision!

EN

- 3 - EN

► Do not employ the foot switch when only the compressed air supply hose is connected. The loose hose could wrap around itself and cause serious injury. ► It is the responsibility of the operator that national regulations during operation and regarding a repeated safety inspection of electrical equipment are complied with. For Germany these are BGV A3 in relation with VDE 0701-0702.
