Cooling System; Muffler; Reconstructing The Blade - Husqvarna K960 Ring Operator's Manual

Cooling system

To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1 Air intake on the starter.
2 Air guide plate.
3 Fins on the flywheel.
4 Cooling fins on the cylinder.
5 Cylinder cover
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.
Muffler
The muffler is designed to reduce the noise level and to direct
the exhaust gases away from the operator. The exhaust
gases are hot and can contain sparks, which may cause fire
if directed against dry and combustible material.
Never use a machine with a defective muffler.
MAINTENANCE

Reconstructing the blade

!
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.
