SAFETY INSTRUCTIONS
General working instructions
Before using a chain saw you must understand the effects of 
kickback and how to avoid them. See instructions under the 
heading How to avoid kickback.
Before using a chain saw you must understand the difference 
between cutting with the top and bottom edges of the bar. See 
instructions under the heading How to avoid kickback.
Basic safety rules
Look around you: 
-
To ensure that people, animals or other things cannot 
affect your control of the machine.
-
To make sure that none of the above might come 
within reach of your saw or be injured by falling trees.
Follow the instructions above, but do not use a chain saw in a 
situation where you cannot call for help in case of an accident.
Do not use the machine in bad weather, such as dense 
fog, heavy rain, strong wind, intense cold, etc. Working in 
bad weather is tiring and often brings added risks, such as 
icy ground, unpredictable felling direction, etc.
Take great care when removing small branches and avoid 
cutting bushes (i.e. cutting many small branches at the 
same time). Small branches can be grabbed by the chain 
and thrown back at you, causing serious injury.
Make sure you can move and stand safely. Check the area 
around you for possible obstacles (roots, rocks, branches, 
ditches, etc.) in case you have to move suddenly. Take 
great care when working on sloping ground.
Take the utmost care when cutting through branches or 
logs that are in tension. A log or branch that is in tension 
can suddenly spring back into its natural position before or 
after you cut it. If you stand on the wrong side or start 
cutting in the wrong place it may strike you or your chain 
saw, so that you lose control. Both situations could cause 
serious injury.
Before moving your chain saw switch off the engine and 
lock the chain using the chain brake. Carry the chain saw 
with the bar and chain pointing backwards. Fit a guard to 
the bar before transporting the chain saw or carrying it for 
any distance.
Never put a chain saw down while the engine is running 
unless you have it in clear view and the chain brake is on. 
Switch the engine off before leaving your chain saw for 
any length of time.
Basic cutting technique
General
Always use full throttle when cutting!
Reduce the speed to idle after every cut (running the 
engine for too long at full throttle without any load, i.e. 
without any resistance from the chain during cutting, can 
lead to serious engine damage).
Cutting from above = Cutting on the pull stroke.
Cutting from below = Cutting on the push stroke.
Cutting on the push stroke increases the risk of kickback. See 
instructions under the heading How to avoid kickback.
Terms
Cutting = General term for cutting through wood.
Limbing = Cutting branches off a felled tree.
Splitting = When the object you are cutting breaks off before 
the cut is complete.
