Reconstructing the blade
NOTICE! The air filter must not be cleaned or blown clean 
with compressed air. This will damage the filter.
!
WARNING! Ring cutter blades must not be 
reconstructed. Due to its design, a ring 
cutter blade is exposed to other strains than 
a centre driven 14 inch diamond blade. 
Firstly, the drive wheel is driven on the inner 
diameter of the blade so that both the 
surfaces of the drive wheel and the blade are 
exposed to wear. The core of the blade 
becomes thinner and the guide wider, which 
prevents the blade being driven by the 
wheel. Secondly, the blade is exposed to 
loads from the rollers and from the actual 
cutting process when the blade is not held 
completely straight. Strain builds up in the 
blade until it cracks or breaks if it has been 
reconstructed. A shattered blade can cause 
serious personal injuries to the user or other 
persons. For this reason Husqvarna does 
not approve ring cutting blades that have 
been reconstructed. Contact your 
Husqvarna dealer for instructions.
