Tips on chain saw use
Sawing up wood (Fig 7a, 7b)
To saw up wood, please observe the safety regulations and proceed as follows: Make sure the wood to
be sawed cannot slip. Clamp short pieces of wood in place before sawing. Saw only wood or wooden
objects. When sawing, make sure that no stones or nails are touched as these could be thrown out and
damage the saw chain. Avoid bringing the running saw into contact with wire fences or the ground. When
lopping off branches, support the chainsaw as far as possible and do not saw with the tip of the guide bar.
Watch out for obstacles such as tree stumps, roots, ditches and hillocks as these could cause you to fall.
Remember:
The chainsaw must be running before it comes into contact with the wood.
To switch on: Press the safety lock-off (2) and ON/OFF switch on (13). Place the lowest claw (Fig 4, J)
on the wood . Raise the chain saw by the rear grip (2) and saw into the wood. Move the chain saw back
a little and place the claw further down. Be careful when sawing splintered wood as pieces of wood may
be ripped off.
Wood under tension
Fig, 11a: Top side of wood under tension
Danger: Tree will rear up!
Fig, 11b: Bottom side of wood under tension
Danger: Tree will move downwards!
Fig, 11c: Thick trunks and high tension
Danger: Tree will move suddenly and with immense force!
Fig, 11d: Both sides of trunk under tension
Danger: Tree will move sideways.
Felling trees
To fell trees, observe all the safety regulations and proceed as follows:
The chain saw may be used to fell only trees which are smaller in diameter than the length of the motor.
If the saw chain gets jammed, release it using a wooden wedge.
Remember:
Danger zone: Falling trees can bring down other trees with them. The danger zone is therefore twice the
length of the tree being felled. (Fig, 12)
Felling trees is dangerous and requires practice. If you are a beginner or inexperienced, do not try
to teach yourself but seek professional training. (Fig, 13)
Falling direction:
• Note that the falling direction can be severely influenced by wind or weight / branch distribution
in the tree. In some cases, the tree should be guided by ropes or cables.
• First estimate the direction of fall, taking into account the centre of gravity of the crown and the wind
direction. The chain saw must be running before it comes into contact with the wood. Switch on the
chain saw. Saw an undercut in the tree in the direction of fall and then make a horizontal cut (back cut)
on the side opposite to the undercut.
• Make the undercut: This will give the tree a direction and guidance.
• Check the direction of fall: If you have to correct the undercut, always re-cut over the entire width.
• Call out “Timber!“
• Only now make the back cut, which must be higher than the sole of the undercut. Insert wedges in time.
• Leave the bridge in place as it will function as a hinge. If you cut through the bridge, the tree will fall
randomly.
