WARNING The muffler becomes very hot

There is a risk of fire, especially when you
operate the product near flammable
materials and/or fumes.
WARNING Do not operate a product without
a muffler or with a defective muffler. A
defective muffler can increase the noise
level and the risk of fire. Keep fire
extinguishing tools near. Do not use a
product without, or with a broken, spark
arrestor mesh if you must have a spark
arrestor mesh in your area.
The muffler keeps the noise levels to a minimum and

areas with a hot, dry weather there is a high risk of fire.
