Muffler; General Maintenance Instructions - Husqvarna K750 Operator's Manual

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.
