1.3 Proper use
The Wöhler DH 420 Pneumatic Viper is equipped
with a digital meter counter; it is designed to clean
ventilation systems in conjunction with corre-
sponding accessories and an air compressor.
When cleaning chimneys and ventilation systems
lined with asbestos-based material the Wöhler DH
420 should be used in combination with the spe-
cial sweeping unit for asbestos (see accessories)
using water instead of compressed air. In such
cases, the operating manual for the asbestos
sweeping unit describes in detail the connections
and how to use the unit.
Any other use is considered improper use.
