Warning! 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
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.
Operation - tips on chain saw use
Important Notes
Use the device exclusively for sawing wood.
•
Do not cut metal, plastics, masonry, building
material that is not made of wood, etc.
• Turn off the engine when the saw comes into
contact with a foreign object. Inspect the saw
and repair it if necessary.
• Protect the chain from dirt and sand. Even a
small amount of dirt will quickly blunt a chain and
increase the risk of kickback.
Start by cutting a few small logs, using the
•
exercise to get a feel for your device before you
tackle more difficult tasks.
• Press the casing of the chain saw against the
log when you start sawing.
Allow the saw to work. Exert only slight
•
downward pressure.
In order not to lose control of the device you
•
should lean towards the end of the incision so
there is no pressure on the saw.
Felling Trees – Only after appropriate training
Caution: Watch for broken or dead branches that
could fall during sawing and cause serious injury. Do
not saw near buildings or electrical wires if you do

not know in which direction the felled tree could fall.
Do not work at night since you will not be able to see
properly, or in rain, snow or storm, as it is difficult to
predict the the direction in which the tree could fall.
Plan your work in advance.
•
• The work area around the tree should be clear
so you have a firm foothold.
The operator should always stand on the uphill
•
side of the terrain as the tree is expected to roll
or slide after felling.
• Check for broken or dead branches, which can
fall and cause serious injury.
The following conditions may affect the direction in
which a tree falls:
• Wind direction and speed.
Lean of the tree. The inclination is not always
•
visible due to uneven or sloping terrain.
Determine the lean of the tree using a solder or
a spirit level.
• Branch growth (and hence weight) on one side
only.
• Surrounding trees and obstacles.
If two or more people are involved in the cutting and
felling, the distance between those who are felling
and cutting should be at least twice the height of the
tree to be felled. When felling trees, make sure that
other people are not put at risk, that supply lines are
not hit and that no material damage is caused. If a
tree comes in contact with a supply line, the supply
company has to be notified immediately.
Look for decay and rot. If the trunk is rotted, it may
suddenly collapse and fall on you. Make sure there
is enough space for the tree to fall safely. Keep
a distance of 2 1/2 tree lengths from the nearest
person or other objects. Engine noise can drown out
a warning call.
Remove dirt, stones, loose bark, nails, staples, and
wire from the tree where you are going to cut.
Keep an escape route (Fig. A)
Before felling, an escape route has to be planned
and cleared, if necessary. The escape route should
lead diagonally away from the back of the falling tree
(Fig. A).
Item 1: Plan of emergency exits
Item 2: Position in which the tree falls
Felling of large trees - only with appropriate
training
(15 cm in diameter)
Fell large trees using the notch method. Here, a
wedge is laterally cut out of the tree according to the
desired direction of fall. After a cut has been made
on the case of the other side of the tree, the tree will
fall in the direction of the wedge.
m Note: If the tree has large prop roots, they should
be removed before making the notch. If the saw is
used to remove the prop roots, the chain should
not touch the ground, to prevent it from becoming
become blunt.
