Oil container
Fill level of the oil container. Even while working, keep
checking that sufficient oil is in the system. To avoid da -
maging the chainsaw, never run the saw if there is no oil
in the system or if the oil drops below the “min” mark. On
average, a single filling will last around 15 minutes de -
pending on the number of pauses in cutting and the loads
involved.
Saw chain
Tension of the saw chain, condition of the cutting ele-
ments. The sharper the chainsaw, the easier and more
controllable it is to operate the chainsaw. The same also
applies to the chain tension. Again, while working also
check the chain tension every 10 minutes in order to in-
crease your safety. New saw chains in particular often
tend to expand more.
Chain brake
Check the operation of the chain brake as described in
the chapter “Safety devices” and then release it.
Safety clothing
Always wear appropriate tight-fitting safety clothing
like special trousers which protect against cuts, protec-
tive gloves and safety shoes.
Hearing protection and protective goggles.
When felling trees or performing forest work, always
wear a protective helmet with integral face and hearing
protection. This will offer protection against falling bran -
ches and any branches if they spring back.
5.2 Description of the correct procedures for basic
use of the chainsaw
Felling a tree
If two or more persons are working at the same time
on felling and cutting back then the minimum distance
between the tree being felled and the tree being cut back
should be at least twice the height of the tree being fel-
led. When felling trees, care must be taken to ensure that
no other persons are endangered, no power supply lines
are hit and no material damage is caused to equipment or
property. In the event that a tree comes into contact with
a power supply line, he responsible power supply compa-
ny should be informed immediately. When working with
the saw on a slope, the operator of the chainsaw must
be standing at a higher point on the slope than the tree
being felled, as the tree will roll or slip downhill once it
has been felled. Before felling the tree you must first plan
and if necessary clear an escape route. This escape route
must lead away diagonally in the opposite direction to the
expected fall direction – this can be seen in Fig. 16 (A=
danger zone, B= direction of fall, C= escape zone).
Before felling the tree you must take into account the
natural inclination of the tree, the location of larger bran-
ches and the wind direction, as this will help you to cor-
rectly determine the direction in which the tree will fall.
Dirt, stones, loose bark, nails, staples and wire must be
removed from the tree.
Making the felling notch
Cut a notch (A) at right angles to the fall direction to a
depth of 1/3 of the tree diameter as shown in Fig. 17. First
make the lower horizontal felling notch (1). This prevents
the saw chain or the guide rail from becoming trapped
when the second felling notch is made.
Making the felling cut
The felling cut should be positioned at least 50 mm
above the horizontal felling notch. Make the felling cut
(B) parallel to the horizontal felling notch. The felling cut
should be cut to a depth which leaves a thin strip (fel-
ling hinge strip) (D) which can act as a hinge. This strip
prevents the tree from rotating and falling in the wrong
direction. Do not cut through the strip. When the felling
cut gets close to the strip the tree should start to fall. If
it becomes clear that the tree may well fall in a different
direction to the desired fall direction (C) or it starts to lean
back and traps the saw chain, interrupt the felling cut and
insert wedges made of wood, plastic or aluminum to open
out the cut and control the lean of the tree until it leans in
the required direction.
When the tree starts to fall, remove the chainsaw from
the cut, switch it off, place it on the ground and exit the
danger zone via the planned escape route. Watch out for
falling branches and take care not to trip.
Removing branches
Here we are talking about removing branches from the
felled tree. When removing branches, leave any down-
ward facing branches which are supporting the tree until
the trunk of the tree has been cut up. Smaller branches
should be removed as shown in Fig. 18 (A= cutting di-
rection when removing branches, B= keep away from
the ground! Supporting branches should be left until the
trunk is cut up) in a single cut from the bottom to the top.
Any branches which are under tension should be cut from
the bottom to the top to prevent the saw from becoming
trapped.
Cutting the tree trunk into lengths
Here we are looking at the process of cutting the felled
tree into sections. Make sure you have a sure footing and
distribute your body weight evenly onto both feet. If pos-
sible the trunk should be underlaid and supported with
branches, beams or wedges. For easy cutting follow the
simple instructions below. If the full length of the tree
