Before cutting down a tree ensure that
a) only those people are within the working area which
are actually involved in cutting down the tree.
b) every worker involved can withdraw without stumbling
(the people should withdraw backwards in a diagonal
line, i. e. at a degree of 45°).
c) the bottom part of the trunk is free from foreign
objects, underbrush and branches. Make sure to have
a safe footing (risk of stumbling).
d) the next working place is at least 2 1/2 tree lengths
away (Fig. 18). Before cutting down the tree check the
direction of fall and make sure that there are neither
people nor objects within a distance of 2 1/2 tree
lengths.
(1) = cutting down area
-
Judging the tree:
Direction of hanging - loose or dry branches - height of the
tree - natural overhang - is the tree rotten?
-
Take into account the direction and speed of the wind. If
strong gusts are occurring, do not do any felling.
-
Cutting the roots:
Start with the strongest root. First do the vertical and then
the horizontal cut.
-
Notching the trunk (Fig. 19, A):
The notch determines the direction of fall and guides the
tree. The trunk is notched perpendicular to the direction of
fall and penetrates 1/3 -1/5 of the trunk diameter. Perform
the cut near the ground.
-
When correcting the cut, always do so over the whole
width of the notch.
-
Cut down the tree (Fig. 20, B) above the bottom edge
of the notch (D). The cut must be exactly horizontal. The
distance between both cuts must be approx. 1/10 of the
trunk diameter.
-
The material between both cuts (C) serves as a hinge.
Never cut it through, otherwise the tree will fall without any
control. Insert felling wedges in time.
-
Secure the cut only with wedges made of plastic or
aluminium. Do not use iron wedges. If the saw hits an iron
wedge the chain can be seriously damaged or torn.
-
When cutting down a tree always stay sidewards of the
falling tree.
-
When withdrawing after having performed the cut, be alert
for falling branches.
-
When working on sloping ground the user of the chain
saw must stay above or sidewards of the trunk to be cut
or the tree already cut down.
-
Be alert for trunks which may roll towards you.
3-8. Transport and storage
-
When changing your location during work switch off
the chain saw and actuate the chain brake in order to
prevent an inadvertent start of the chain.
-
Never carry or transport the chain saw with the chain
running.
-
When the saw is hot, do not cover it (with a tarp,
blanket, newspaper or the like).
Let the saw cool down before putting it in a storage
case or vehicle. Saws with catalytic converter take
longer to cool down!
-
When transporting the chain saw over long distances the
chain protection cover (delivered with the chain saw) must
be applied.
-
Carry the chain saw with the tubular handle. The guide
bar points backwards (Fig. 21). Avoid coming in contact
with the muffler (danger of burns).
-
Ensure safe positioning of the chain saw during car trans-
portation to avoid fuel or chain oil leakage.
-
Store the chain saw safely in a dry place. It must not be
18
stored outdoors. Keep the chain saw away from children.
The chain protection cover should always be put on.
-
Before storing the chain saw over a long period of time
or shipping it the fuel and oil tanks must be completely
emptied.
3-9. Maintenance
-
Before performing maintenance work switch off the
chain saw (Fig. 22) and pull out the plug cap.
-
Before starting work always check the operating safety
of the chain saw, in particular the function of the chain
brake. Make sure that the chain is always sharpened and
tightened correctly (Fig. 23).
-
Operate the chain saw only at a low noise and emission
level. For this ensure the carburetor is adjusted correctly.
-
Regularly clean the chain saw.
-
Regularly check the tank cap for tightness.
Observe the accident prevention instructions issued
by trade associations and insurance companies. Do
not perform any modifications on the chain saw. You
will put your safety at risk.
Perform only the maintenance and repair works described
in the instruction manual. All other work must be carried
out by DOLMAR Service.
SERVICE
Use only original DOLMAR spare parts and accessories.
Using spare parts other than original DOLMAR parts or
accessories and guide bar/chain combinations or lengths
which are not approved bring a high risk of accidents.
We cannot accept any responsibility for accidents
and damage resulting from using sawing devices or
accessories which have not been approved.
3-10. First aid
For the event of a possible accident, please make sure
that a first aid kit is always immediately available close by.
Immediately replace any items used from the first aid box.
When calling for help, give the following information:
- Place of the accident
- What happened
- Number of injured people
- Kind of injuries
- Your name!
NOTE:
Individuals with poor circulation who are exposed to
excessive vibration may experience injury to blood vessels or
the nervous system.
Vibration may cause the following symptoms to occur in the
fingers, hands or wrists: "Falling asleep" (numbness), tingling,
pain, stabbing sensation, alteration of skin colour or of the
skin.
If any of these symptoms occur, see a physician!
To reduce the risk of vibration white finger, keep your
hands warm, wear gloves, and make sure the saw chain
is sharp.
