5 Use
WARNING! Risk of personal injury
• Vacuuming activities can result in static elec-
tricity. Consult local authorities or your sup-
plier for suitable measures to avoid any risks.
• Only properly trained personnel are allowed
to use this vacuum cleaner.
• Do not use the power cable to pull the vacu-
um cleaner.
• Make sure all modules, hoses, and cables are
securely fastened before use.
• Do not use the vacuum cleaner to collect ma-
terial that is caustic, hot, explosive, highly
flammable, chemically unstable, spontan-
eously ignitable, or which can release sparks.
• Do not use the fan to transport aggressive,
toxic or explosive gases and gases with high
moisture content.
• Do not use if the ambient temperature ex-
ceeds 40°C.
• The fan can become very hot, even during
normal operation.
• Do not expose the body to vacuum inlets
when operating the unit.
• Never put your hand directly at the inlet or
outlet.
• Always use proper protective equipment
such as safety shoes and hearing protection.
• Always use proper protective equipment
where there is a risk for exposure to dust.
• Make sure that no one is near the inlet side
when the fan operates.
• The fan must never be operated without a
wire guard because the rotation impeller can
cause serious injury.
• There is a powerful stream of air from the
discharge side or outlet. Foreign bodies that
might have been sucked into the fan can be
thrown out at high speed and cause injury.
• All foreign objects and debris that could exit
through the fan's outlet must be filtered out
before going through the fan.
• Do not insert objects into the fan through the
outlet.
