2 Safety The maintenance units are intended for maintenance of compressed air
systems in the industrial field. They may be operated in dusty and wet en-
vironments.
Any other use is considered improper.
Installation, commissioning, maintenance and troubleshooting of the
maintenance units may only be performed by authorised qualified person-
nel, who have basic knowledge in pneumatics and mechanics.
All handling of the maintenance units is the responsibility of the operator.
WARNING
Compressed air
A loosened hose which is under pressure can lead to personal injuries.
Opening the maintenance unit under pressure can result in damage to the
maintenance unit and serious injury.
Screw the hose lines on carefully.
Check the hose lines and connections after one hour of operation and
thereafter regularly (generally monthly).
Retighten the hose lines, if necessary.
Ensure that the compressed air is disconnected from the supply lines
during all work on the maintenance units.
Prevent the maintenance units from being switched back on during all
work.
WARNING
Damage to health due to oil mist
Oil mist is generated in the lubricator unit. Escaping oil mist can be harmful
to health.
The operator must ensure that people do not come into contact with or
breathe in escaping oil mist.
Suitable measures, such as the discharge of the oil-containing exhaust
air or the installation of a suitable suction system, must be implement-
ed.
The operator must warn of the dangers of escaping oil mist.
NOTICE
Solvents and aggressive cleaning agents damage the maintenance units.
For cleaning, use only a slightly damp cloth with water and, if necessary, a
mild cleaning agent without chemical additives.
