Installation and Short-Form Operating Manual for FKL 100/150/200 si
The pneumatic knockers (FKL) comply with the EG Machinery Directive 2006/42/EG. They also comply, in
particular, with Standard DIN EN ISO 12100, Parts 1 and 2.
Important Information
FINDEVA AG is unable to accept responsibility whatsoever for damage to property or injury if technical
modifications are made to the product or if the information and instructions in this Operating Manual are not
followed.
Pneumatic vibrators must be installed and operated by an experienced person.
Risk of injury!
•
Compressed-air units, such a vibrators, filters, oilers and the air hoses, may be very highly
pressurised. The system must be disconnected from the compressed air supply before such
units are installed or serviced. The units must be depressurised.
•
Air pressure may produce extremely loud noise. Consequently, all persons in the surrounding
area of the pneumatic vibrator must wear ear defenders.
•
Comply with national and local regulations and regulations governing installation and use of
pneumatic systems.
Noise level
•
The noise level of a non-shielded knocker fitted on a metal panel exceeds 85 dB(A), if only the
single noise event is considered. The sustained level is below this, depending on impact
sequence. The noise emitted by the device may be attenuated by sheathings or coverings.
•
Noise defenders must be worn in the noise area.
Attachment of the knocker
•
Vibrators or knockers and parts of the structure may become detached as the result of
vibration. Screw and nut locking devices must be used.
Lubrication
The FKL pneumatic knocker can be operated with dry compressed air and, thus, unlubricated. If compressed air
containing oil is selected for operation of the knocker, such air must be also be used always since the basic
lubrication of the knocker is flushed out as the result of the air containing oil. The basic version of the knocker
can be operated in a temperature range from –20°C to 80°C. A special version is available for temperatures
between –40°C and 130°C.
Air filter and pressure controller
All compressors feature air filters. However, use an air filter with a particle permeability rating of 5 um. This will
help to prolong the knocker's service life.
