•Never start a chain saw unless the bar, chain and all 
covers are fitted correctly. See instructions under the 
heading Assembly. Without a bar and chain attached 
to the chain saw the clutch can come loose and cause 
serious injury.
• The chain brake should be activated when starting. 
Se instructions under the heading Start and stop. Do 
not drop start. This method is very dangerous 
because you may lose control of the saw.
• Never start...

6Before 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.
7 When you put the chain saw on the ground, lock the 
saw chain using the chain brake and ensure you have 
a constant view of the machine. Switch the engine off 
before leaving your chain saw for...

the saw chain is jamming, the saw may be pushed 
back at you.
8 Unless the user resists this pushing force there is a 
risk that the chain saw will move so far backwards that 
only the kickback zone of the bar is in contact with the 
tree, which will lead to a kickback.
Cutting with the bottom edge of the bar, i.e. from the 
top of the object downwards, is known as cutting on 
the pull stroke. In this case the chain saw pulls itself 
towards...

The following instructions describe how to handle the 
commonest situations you are likely to encounter when 
using a chain saw.
Limbing
When limbing thick branches you should use the same 
approach as for cutting.
Cut difficult branches piece by piece.
Cutting
If you have a pile of logs, each log you attempt to cut 
should be removed from the pile, placed on a saw horse 
or runners and cut individually.
Remove the cut pieces from the cutting...

Felling direction
The aim is to fell the tree in a position where you can limb 
and cross-cut the log as easily as possible. You want it to 
fall in a location where you can stand and move about 
safely.
Once you have decided which way you want the tree to fall 
you must judge which way the tree would fall naturally.
Several factors affect this:
• Lean of the tree
• Bend
• Wind direction
• Arrangement of branches
• Weight of snow
• Obstacles...

Next make the bottom cut so that it finishes exactly at the 
end of the top cut.
The directional cuts should run 1/4 of the diameter 
through the trunk and the angle between the top cut and 
bottom cut should be 45
°.
The line where the two cuts meet is called the directional 
cut line. This line should be perfectly horizontal and at 
right angles (90
°) to the chosen felling direction.
Felling cut
The felling cut is made from the opposite side...

Freeing a tree that has fallen badly 
Freeing a ”trapped tree”
It is very dangerous to remove a trapped tree and there is 
high accident risk.
Never try to fell the tree that is trapped.
Never work in the risk zone of the hanging trapped tree.
The safest method is to use a winch.
• Tractor-mounted
• Portable
Cutting trees and branches that are in tension
Preparations: Work out which side is in tension and where 
the point of maximum tension is...

How to avoid kickback
What is kickback?
The word kickback is used to describe the sudden 
reaction that causes the chain saw and bar to jump off an 
object when the upper quadrant of the tip of the bar, 
known as the kickback zone, touches an object.
Kickback always occurs in the cutting plane of the bar. 
Normally the chain saw and bar are thrown backwards 
and upwards towards the user. However, the chain saw 
may move in a different direction...
