- Never work and climb into a tree with the chain saw
without an appropriate restraint system for men and
machine.
- We recommend always using a rising platform for
sawing.
- Don't overreach.
- Position the chain saw in such a way that your body
is clear of the cutting attachment whenever the en-
gine is running.
- Only cut wood with the chain saw.
- Don't touch the ground with the running chain saw.
- Do not use the chainsaw to pry or shovel away
when removing pieces of wood or other objects.
- Clean the cutting area of foreign bodies such as
sand, stones, nails, etc. Foreign bodies damage
the saw equipment and can result in dangerous
kickback.
- When cutting sawn wood use a safe ground (if pos-
sible use a sawhorse). Never permit another per-
son to hold the log. Never hold the log with your
leg or foot.
- Round wood or logs should be secured against
turning while they are being cut.
- For felling or cross-cutting, the spike bar (claw
stop) must be applied to the wood to be cut.
The use of the spike bar is also recommended
when cutting through thick branches.
- Before every cross-cut, firmly position the spike
bar and only then saw into the wood with the chain-
saw running. The saw is then lifted up using the
rear grip and guided using the front handle. The
spike bar acts as a pivot point. Repositioning is
done using light pressure on the front handle. Pull
the saw back slightly to do this.
Insert the spike bar deeper and lift up again using
the rear grip.
- Plunge and longitudinal cuts may only be per-
formed by specially trained personnel (in-
creased risk of kickback).
- Longitudinal cuts may only be done at as shallow
an angle as possible. It is particularly important to
be careful here, as the spike bar cannot engage.
- Only ever pull the saw equipment from the wood
with the chain running.
- If multiple cuts are to be performed, the throttle le-
ver must be released between cuts.
- Take care when cutting splintery wood. Cut pieces
of wood can be carried away (risk of injury).
- When cutting using the top of the bar, the chain-
saw can be pushed towards the operator if the
chain bind up. For this reason, if possible, cut using
the bottom side of the bar as the saw will be pulled
away from the body towards the wood.
- Logs under strain require special attention to pre-
vent the saw from pinching. The first cut is made on
the compression side to relieve the stress on the
log. Only then perform the separating cut using the
opposite side. If the saw pinches stop the engine
and remove it from the log.

CAUTION!:
Felling and branch removal work as well as work
on wind damage may only be performed by
trained personnel! Risk of injury!
- When removing branches, support the chainsaw
on the trunk if possible. You must not cut using the
tip of the bar to do this (risk of kickback).
- Be extremely cautious when cutting limbs under
tension. The limbs could spring back toward the op-
erator and cause loss of control of the saw or injury
to the operator. Do not cut freely hanging branch-
es from below.
- When bucking, do not stand on the log!
- Felling work may only be started when it has
been ensured that:
a) Only persons involved in the felling work are in
the felling area,
b) An obstacle free path to the rear is available for
everyone involved in the felling work (this rear-
wards path must run straight back at approx.
45°).
c) The trunk base must be free from all foreign bod-
ies, brushwood and branches. Make sure you
have firm footing (risk of stumbling).
d) When felling, maintain a distance of at least 2
1/2 tree lengths from the nearest person and any
other objects!
- Observing the general condition of the tree:
The neutral lean of the tree - dry and loosely hang-
ing branches - height of the tree -natural overhang
- is the tree rotted?
- Observe the wind direction and speed. Felling work
must not be done when there are strong gusts of
wind. Avoid sawdust (pay attention to the wind di-
rection!)
- Cutting the trunk base swelling:
If the tree has large buttress roots, cut into the larg-
est buttresses vertically first (horizontally next) and
remove
- Placing a felling notch:
The felling notch when properly placed determines
the direction in which the tree will fall. It is made per-
pendicular to the line of fall and should be as close
to the ground as possible. Cut the felling notch to
a depth of about 1/3 to 1/5 of the trunk diameter. It
should be in no case higher than it is deep. Make
the felling notch very carefully.
- Any notch corrections must be cut across the whole
width.
- Begin the felling cut slighty higher than the felling
notch and on the opposite side of the tree. Then
cut horizontally through towards the felling notch.
Apply the chain saw with its spikes directly behind
the uncut portion of wood and cut toward the notch
Leave approximately 1/10 of the tree diameter un-
cut! This is the hinge
- Do not cut through the hinge because you could
lose control of the direction of the fall. Drive wedg-
es into the felling cut where necessary to control
the direction of the fall!
