WARNING:
Prior to starting work, check the mains connection
cable and extension cable for damage. Only use
mains connection cables and extension cables in
perfect condition.
WARNING:
The electrical system to which the chain saw is
connected should be equipped with a differential
current safety switch (with a max. of 30mA release
current).
It is advisable to use the cord retainer in the back handle
of the chain saw to avoid accidental disconnection of the
power supply.
BEFORE OPERATION
In order to prevent kickback, please follow these safety
instructions:
■ Never cut with the tip of the chain bar! Be careful when
continuing cuts you are already working on!
■ Always start cuts with the chain saw already running.
■ Make sure that the saw chain is always properly
sharpened.
■ Never cut through more than one branch at a time!
When lopping off branches, be careful not to touch any
other branches.
a. When cross-cutting, pay attention to trunks standing
very close to each other. If possible use a sawing
trestle.
TRANSPORTING THE CHAIN SAW
Before transporting the chain saw, always remove the
plug from the power socket and slide the chain cover over
the bar and chain. If several cuts are to be performed with
the chain saw, the saw must be switched off between cuts.
CHAIN GUARD (FIG. 2)
The chain cover must be clipped onto the chain and bar
as soon as the sawing work has been completed and
whenever the machine has to be transported.
OPERATION
WARNING:
Wear eye, ear and body clothing protection while
using your saw. Ensure the oil tank is full before
use.
■ Releasing the chain brake.
To be able to use the chain saw again, the saw chain
must be unlocked, firstly switch off the saw release
the on/off switch completely and then pull the chain
brake back towards the back of the chain saw until it
locks into place. The chain will now move when it is
switched on.
■ Holding the chain saw (Fig. 8)
Always grip both handles with the thumbs and fingers
encircling the handles. Ensure that your left hand is
holding the handle so that your thumb is underneath.
■ Using the chain saw
Always be sure of your footing and hold the chain saw
firmly with both hands while the motor is running.
■ Felling a tree (Fig. 9)
When bucking and felling operations are being
performed by two or more persons at the same time,
the felling operation should be separated from the
bucking operation by a distance of at least twice the
height of the tree being felled. Trees should not be
felled in a manner that would endanger any person,
strike any utility line or cause any property damage.
If the tree does make contact with any utility line, the
utility company should be notified immediately.
The chain saw operator should keep on the uphill side
of the terrain as the tree is likely to roll or slide downhill
after it is felled an escape path
An escape path should be planned and cleared as
necessary before cuts are started. The escape path
should extend back and diagonally to the rear of
expected line of fall as illustrated in Fig. 9.
Before felling is started, consider the natural lean of
the tree, the location of larger branches and the wind
direction to judge which may the tree will fall.
Remove dirt, stones, loose bark, nails, stapes and wire
from the tree.
■ Notching undercut (A notch cut in a tree to direct the
fall) (Fig. 10)
Make the notch 1/3 the diameter of the tree,
perpendicular to the direction of falls. Make the lower
horizontal notching cut first, this will help to avoid
pinching of either the saw chain or the guide bar when
the second notch is being made.
■ Felling back cut (the final cut in a tree felling operation,
made on the opposite side of the tree from the notching
undercut) (Fig. 10)
Make the felling back cut at least 50mm higher than
the horizontal notching cut. Keep the felling back cut
parallel to the horizontal notching cut. Make the felling
back cut so enough wood is left to act as a hinge. The
hinge wood keeps the tree from twisting and falling in
the wrong direction. Do not cut through the hinge. As
the felling cut gets close to the hinge, the tree should
begin to fall. If there is any chance that the tree may
