GENERAL SAFETY PRECAUTIONS
Muffler
The muffler is designed to keep noise levels to a minimum 
and to direct exhaust fumes away from the user.
In areas with a hot, dry climate there is a high risk of fires. 
These areas are sometimes subject to government rules 
requiring among other things the muffler must be equipped 
with an approved type of spark arrestor mesh.
Cutting equipment
This section describes how to choose and maintain your 
cutting equipment in order to:
Reduce the risk of kickback.
Reduce the risk of the saw chain breaking or jumping off 
the bar.
Obtain optimal cutting performance.
Extend the life of cutting equipment.
Avoid increasing vibration levels.
General rules
Only use cutting equipment recommended by us!  
See instructions under the heading Technical data.
Keep the chain’s cutting teeth properly sharpened!  
Follow our instructions and use the recommended file 
gauge.
 A damaged or badly sharpened chain increases 
the risk of accidents.
Maintain the correct depth gauge setting! Follow our 
instructions and use the recommended depth gauge 
clearance.
 Too large a clearance increases the risk of 
kickback.
Keep the chain properly tensioned! If the chain is slack 
it is more likely to jump off and lead to increased wear on 
the bar, chain and drive sprocket.
Keep cutting equipment well lubricated and properly 
maintained!
  A poorly lubricated chain is more likely to 
break and lead to increased wear on the bar, chain and 
drive sprocket.
Cutting equipment designed to reduce 
kickback
The only way to avoid kickback is to make sure that the 
kickback zone of the bar never touches anything.
By using cutting equipment with ”built-in” kickback reduction 
and keeping the chain sharp and well-maintained you can 
reduce the effects of kickback.
Bar
The smaller the tip radius the lower the chance of kickback.
Chain
A chain is made up of a number of links, which are available 
in standard and low-kickback versions.
Some terms that describe the bar and chain
To maintain the safety features of the cutting equipment, you 
should replace a worn or damaged bar or chain with a bar and 
chain combinations recommended by Husqvarna. See 
instructions under the heading Technical Data for a list of 
replacement bar and chain combinations we recommend.
!
WARNING! The exhaust fumes from the 
engine are hot and may contain sparks 
which can start a fire. Never start the 
machine indoors or near combustible 
material!
CAUTION! The muffler gets very hot during and after use. 
This also applies during idling. Be aware of the fire hazard, 
especially when working near flammable substances and/
or vapours.
!
WARNING! Never use a saw without a 
muffler, or with a damaged muffler. A 
damaged muffler may substantially increase 
the noise level and the fire hazard. Keep fire 
fighting equipment handy. If a spark arrestor 
screen is required in your area, never use 
the saw without or with a broken spark 
arrestor screen.
!
WARNING! Faulty cutting equipment or the 
wrong combination of bar and saw chain 
increases the risk of kickback! Only use the 
bar/saw chain combinations we recommend, 
and follow the filing instructions. See 
instructions under the heading Technical 
data.
IMPORTANT! No saw chain design eliminates the danger 
of kickback.
!
WARNING! Any contact with a rotating saw 
chain can cause extremely serious injuries.
