ELECTRIC CHAIN SAW
chain guard.
Chainsaw protection
Never use the chainsaw in the rain or in damp conditions.
If the extension cable is damaged, pull the plug out of the power socket immediately. Never work with a
damaged cable.
Check the chainsaw for damage. Before using your tool again, check the safety devices or any slightly
damaged parts to ensure that they are in good working order. Make sure the moving parts are working
correctly. All the parts must be correctly assembled and meet all the conditions required to ensure that the
chainsaw works correctly. Any damaged safety devices and parts must be properly repaired or replaced
immediately by a Customer Service workshop, unless there are instructions to the contrary in these
operating instructions.
Notes on working practice
Kick-back (Fig 8)
You can avoid accidents by not sawing with the tip of the guide bar as this may cause the saw to rear up
suddenly.
Always use the complete safety equipment and clothes when working with the saw.
Kick-back is an upward and/or backward movement of the guide bar which can occur if the saw chain at the
tip of the guide bar encounters an obstruction.
Make sure your work-piece is firmly secured. Use clamps to stop the work-piece slipping. This also makes it
easier to operate the chainsaw with both hands.
Kick-back causes the saw to behave uncontrollably and thus brings with a slack or blunt chain. A poorly
sharpened chain increases the risk of kick-back. Never saw above shoulder height.
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 under tension.
Danger: Tree will rear up!
Fig. 11b:
Bottom side of trunk 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 tress which are smaller in diameter than the length of the motor still
running. 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:
•
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.
