3. SAFETY PRECAUTIONS
3-1. Intended use
Power chain saws
This power chain saw may be used only for sawing wood out
of doors. It is intended for the followung uses depending on
its class:
- Professional and mid-class: Use on small, medium
and large trees: felling, limb removal, cutting to length,
thinning.
- Hobby class: Occasional use on small trees, fruit-tree
care, felling, limb removal, cutting to length.
Unauthorized users:
Persons who are not familiar with the Instruction Manual,
children, young people, and persons under the inuence of
drugs, alcohol or medication must not use this saw.
National regulations may restrict the use of the unit!
3-2. General precautions
- To ensure correct operation the user has to read this
instruction manual (Fig. 2) to make himself familiar with
the charac teristics of the chain saw. Users insufciently
informed will endanger themselves as well as others due
to improper handling.
- It is recommended to lend the chain saw only to people
who are experienced in working with chain saws. Always
hand over the instruction manual.
- First users should ask the dealer for basic instructions
to become familiarized with the characteristics of engine
powered sawing or even attend a recognized course of
instruction.
- Children and young persons aged under 18 years must
not be allowed to operate the chain saw. Persons over the
age of 16 years may, however, use the chain saw for the
purpose of being trained as long as they are under the
supervision of a qualied trainer.
- Use chain saws always with the utmost care and
attention.
- Operate the chain saw only if you are in good physical
condition. If you are tired, your attention will be reduced.
Be especially careful at the end of a working day. Perform
all work calmly and carefully. The user has to accept
liability for others.
- Never use the chain saw after having consumed alcohol,
drugs or medication. (Fig. 3)
- A re extinguisher must be available in the immediate
vicinity when working in easily inammable vegetation or
when it has not rained for a long time (danger of re).
3-3. Protective equipment (Fig. 4 & 5)
- In order to avoid head, eye, hand or foot injuries
as well as to protect your hearing the following
protective equipment must be used during operation
of the chain saw:
- The kind of clothing should be appropriate, i. e. it should
be tight-tting but not be a hindrance. Do not wear
jewellery or clothing which could become entangled with
bushes or shrubs. If you have long hair, always wear a
hairnet!
- It is necessary to wear a protective helmet whenever
working with the chain saw. The protective helmet (1)
is to be checked in regular intervals for damage and is to
be replaced after 5 years at the latest. Use only approved
protective helmets.
- The face shield (2) of the protective helmet (or the
goggles) protects against sawdust and wood chips. During
operation of the chain saw always wear a goggle or a face
shield to prevent eye injuries.
- Wear adequate noise protection equipment (ear
muffs (3), ear plugs, etc.). Octave band analysis may be
provided upon request.
- The safety jacket (4) is provided with special signal-
coloured shoulder straps and is comfortable and easy to
care for.
- The protective brace and bib overall (5) is made of a
nylon fabric with multiple layers and protects against cuts.
We strongly recommend its use.
- Protective gloves (6) made of thick leather are part of the
prescribed equipment and must always be worn during
operation of the chain saw.
- During operation of the chain saw safety shoes or safety
boots (7) tted with anti skid sole, steel toe caps and
protection for the leg must always to be worn. Safety
shoes equipped with a protective layer provide protection
against cuts and ensure a secure footing.
- Sawing dry wood can create dust. Use a suitable dust
mask.
3-4. Fuels/Refuelling
- Stop the engine before refuelling the chain saw.
- Do not smoke or work near open res (Fig. 6).
- Let the engine cool down before refuelling.
- Fuels can contain substances similar to solvents. Eyes
and skin should not come in contact with mineral oil
products. Always wear protective gloves when refuelling.
Frequently clean and change protective clothes. Do not
breathe in fuel vapors. Inhalation of fuel vapours can be
hazardous to your health.
- Do not spill fuel or chain oil. When you have spilt fuel or oil
immediately clean the chain saw. Fuel should not come in
contact with clothes. If your clothes have come in contact
with fuel, change them at once.
- Ensure that no fuel or chain oil oozes into the soil
(environmental protection). Use an appropriate base.
- Refuelling is not allowed in closed rooms. Fuel vapors will
accumulate near the oor (explosion hazard).
- Ensure to rmly tighten the screw plugs of the fuel and oil
tanks.
- Change the place before starting the engine (at least 3 m
from the place of refuelling) (Fig. 7).
- Fuel cannot be stored for an unlimited period of time. Buy
only as much as will be consumed in the near future.
- Use only approved and marked containers for the
transport and storage of fuel and chain oil. Ensure
children have no access to fuel or chain oil.
3-5. Putting into operation
- Do not work on your own. Another person must
be nearby in case of emergencies (within shouting
distance).
- Ensure that there are no children or other people within
the working area. Pay attention to any animals in the
working area, as well (Fig. 8).
- Before starting work the chain saw must be checked
for perfect function and operating safety according to
the prescriptions.
Check especially the function of the chain brake, the
correct mounting of the guide bar, the correct sharpening
and tightening of the chain, the rm mounting of the
sprocket guard, the easy motion of the throttle lever and
the function of the throttle lever lock, the cleanliness and
dryness of the handles, and the function of the ON/OFF
switch.
- Put the chain saw only into operation if it is completely
assembled. Never use the chain saw when it is not
completely assembled.
- Before starting the chain saw ensure that you have a safe
footing.
- Put the chain saw into operation only as described in this
instruction manual (Fig. 9). Other starting methods are not

17
allowed.
- When starting the chain saw it must be well supported
and securely held. The guide bar and chain must not be in
contact with any object.
- When working with the chain saw always hold it with
both hands. Take the back handle with the right hand and
the tubular handle with the left hand. Hold the handles
tightly with your thumbs facing your ngers.
- CAUTION: When releasing the throttle lever the chain
will keep on running for a short period of time (free-
wheeling).
- Continuously ensure that you have a safe footing.
- Hold the chain saw such that you will not breathe in the
exhaust gas. Do not work in closed rooms (danger of
poisoning).
- Switch off the chain saw immediately if you observe
any changes in its operating behavior.
- The engine must be switched off before checking the
chain tension, tightening the chain, replacing it or
clearing malfunctions (Fig. 10).
- When the sawing device is hit by stones, nails or other
hard objects, switch off the engine immediately and check
the sawing device. If the chain saw is exposed to force,
such as through impact or falling, inspect the entire chain
saw for proper functioning.
- When stopping work or leaving the working place, switch
off the chain saw (Fig. 10) and put it down such that
nobody is endangered.
● Maintenance ● Stopping work
● Refuelling ● Transport
● Sharpening the chain ● Putting out of function
CAUTION: Do not put the overheated power chain
saw in dry grass or on any inammable objects.
The mufer is very hot (danger of re).
- CAUTION: Oil dropping from the chain or guide bar after
having stopped the saw chain will pollute the soil. Always
use an appropriate base.
3-6. Kickback
- When working with the chain saw dangerous kickbacks
may occur.
- Kickback occurs when the upper part of the end of the
guide bar inadvertently touches wood or other hard
objects (Fig. 11).
- This causes the saw to be thrown back toward the user
with great force and out of control. Risk of injury!
In order to prevent kickback, follow these rules:
- Only specially-trained persons should perform plunge
cuts, i.e., piercing timber or wood with the tip of the saw!
- Never apply the end of the bar when starting to make a
cut.
- Always observe the end of the guide bar. Be careful when
continuing an already started cut.
- When starting to cut the chain must be running.
- Ensure that the chain is always sharpened correctly. Pay
special attention to the height of the depth limiter.
- Never cut several branches at the same time. When
cutting a branch ensure that no other branch is touched.
- When crosscutting a trunk be aware of the trunks next to
it.
3-7. Working behavior/Method of working
- Only use the chain saw during good light and visibility
periods. Be aware of slippery or wet areas, and of ice and
snow (risk of slipping). The risk of slipping is extremely
high when working on recently peeled wood (bark).
- Never work on unstable surfaces. Make sure that there
are no obstacles in the working area, risk of stumbling.
Always ensure that you have a safe footing.
- Never saw above your shoulder height (Fig. 12).
- Never saw while standing on a ladder (Fig. 12).
- Never climb up into trees to perform sawing with the chain
saw.
- Do not work leaning too far over.
- Guide the chain saw in such a way that no part of your
body is within the elongated swivelling range of the saw
(Fig. 13).
- Use the chain saw for sawing wood only.
- Avoid touching the ground with the chain saw while it is
still running.
- Never use the chain saw for lifting up or removing pieces
of wood or other objects.
- Remove foreign objects such as sand, stones and nails
found within the working area. Foreign objects may
damage the sawing device and can cause dangerous
kickback.
- When sawing precut timber use a safe support (sawing
jack, Fig. 14). Do not steady the workpiece with your foot,
and do not allow anyone else to hold or steady it.
- Secure round pieces against rotation.
- For cutting down trees or performing crosscuts the
spike bar (Fig. 14, Z) must be applied to the wood to
be cut.
- Before performing a crosscut rmly apply the spike bar to
the timber, only then can the timber be cut with the chain
running. For this the chain saw is lifted at the back handle
and guided with the tubular handle. The spike bar serves
as a centre of rotation. Continue by slightly pressing down
the tubular handle and simultaneously pulling back the
chain saw. Apply the spike bar a little bit deeper and once
again lift the back handle.
- When the timber must be pierced for cutting or
longitudinal cuts are to be performed it is urgently
recommended to have this carried out by specially
trained persons only (high risk of kickback).
- When starting a cut, the blade can slip to the side or jump
slightly. This depends on the wood and the condition of
the chain. Therefore, always hold the chain saw with
both hands.
- Do longitudinal - lengthwise - cuts at the lowest
possible angle (Fig. 15). Be very careful when doing this
type of cut, as the spike bar cannot grip.
- The saw must be running whenever you remove the chain
saw from the wood.
- When performing several cuts the throttle lever must be
released in between.
- Be careful when cutting splintery wood. Cut pieces of
wood may be pulled along (risk of injuries).
- When cutting with the upper edge of the guide bar, the
chain saw may be pushed in the direction of the user if the
chain gets clamped. For this reason use the lower edge
of the bar whenever possible. The chain saw will then be
pushed away from you (Fig. 16).
- If the timber is under tension (Fig. 17), rst cut the
pressure side (A). Then the crosscut can be performed on
the tension side (B). Thus clamping of the guide bar can
be avoided.
- At the end of the cut the weight of the chain saw will
cause it to swing through, since it is no longer held by the
cut. Hold it rmly to control this.
CAUTION:
People felling trees or cutting of branches must be
specially trained. High risk of injuries!
- When cutting of branches, the chain saw should be
supported on the trunk. Do not use the end of the bar for
cutting (risk of kickback).
- Be aware of branches under tension. Do not cut free
branches from below.
- Never perform detensioning cuts while standing on the
trunk.
- Before cutting down a tree ensure that

18
a) only those people are within the working area which
are actually involved in cutting down the tree.
b) every worker involved can withdraw without stumbling
(the people should withdraw backwards in a diagonal
line, i. e. at a degree of 45°).
c) the bottom part of the trunk is free from foreign
objects, underbrush and branches. Make sure to have
a safe footing (risk of stumbling).
d) the next working place is at least 2 1/2 tree lengths
away (Fig. 18). Before cutting down the tree check the
direction of fall and make sure that there are neither
people nor objects within a distance of 2 1/2 tree
lengths.
(1) = cutting down area
- Judging the tree:
Direction of hanging - loose or dry branches - height of the
tree - natural overhang - is the tree rotten?
- Take into account the direction and speed of the wind. If
strong gusts are occurring, do not do any felling.
- Cutting the roots:
Start with the strongest root. First do the vertical and then
the horizontal cut.
- Notching the trunk (Fig. 19, A):
The notch determines the direction of fall and guides the
tree. The trunk is notched perpendicular to the direction of
fall and penetrates 1/3 -1/5 of the trunk diameter. Perform
the cut near the ground.
- When correcting the cut, always do so over the whole
width of the notch.
- Cut down the tree (Fig. 20, B) above the bottom edge
of the notch (D). The cut must be exactly horizontal. The
distance between both cuts must be approx. 1/10 of the
trunk diameter.
- The material between both cuts (C) serves as a hinge.
Never cut it through, otherwise the tree will fall without any
control. Insert felling wedges in time.
- Secure the cut only with wedges made of plastic or
aluminium. Do not use iron wedges. If the saw hits an iron
wedge the chain can be seriously damaged or torn.
- When cutting down a tree always stay sidewards of the
falling tree.
- When withdrawing after having performed the cut, be alert
for falling branches.
- When working on sloping ground the user of the chain
saw must stay above or sidewards of the trunk to be cut
or the tree already cut down.
- Be alert for trunks which may roll towards you.
3-8. Transport and storage
- When changing your location during work switch off
the chain saw and actuate the chain brake in order to
prevent an inadvertent start of the chain.
- Never carry or transport the chain saw with the chain
running.
- When the saw is hot, do not cover it (with a tarp,
blanket, newspaper or the like).
Let the saw cool down before putting it in a storage
case or vehicle. Saws with catalytic converter take
longer to cool down!
- When transporting the chain saw over long distances the
chain protection cover (delivered with the chain saw) must
be applied.
- Carry the chain saw with the tubular handle. The guide
bar points backwards (Fig. 21). Avoid coming in contact
with the mufer (danger of burns).
- Ensure safe positioning of the chain saw during car trans-
portation to avoid fuel or chain oil leakage.
- Store the chain saw safely in a dry place. It must not be
stored outdoors. Keep the chain saw away from children.
The chain protection cover should always be put on.
- Before storing the chain saw over a long period of time
or shipping it the fuel and oil tanks must be completely
emptied.
3-9. Maintenance
- Before performing maintenance work switch off the
chain saw (Fig. 22) and pull out the plug cap.
- Before starting work always check the operating safety
of the chain saw, in particular the function of the chain
brake. Make sure that the chain is always sharpened and
tightened correctly (Fig. 23).
- Operate the chain saw only at a low noise and emission
level. For this ensure the carburetor is adjusted correctly.
- Regularly clean the chain saw.
- Regularly check the tank cap for tightness.
Observe the accident prevention instructions issued
by trade associations and insurance companies. Do
not perform any modications on the chain saw. You

6a. Only for models with
fastening nuts on the sprocket
guard
CAUTION:
Before doing any work on the guide bar or chain, always
switch off the engine and pull the plug cap off the
spark plug (see “Replacing the spark plug”). Always wear
protective gloves!
CAUTION:
Start the chain saw only after having assembled it
completely and inspected.
6a-1. Mounting the guide bar and saw chain
Use the universal wrench delivered with the chain saw for the
following work.
Put the chain saw on a stable surface and carry out the
following steps for mounting the guide bar and saw chain:
(Fig. 25)
Release the chain brake by pulling the hand guard (1) in
direction of arrow.
Unscrew retaining nuts (2).
Pull off the sprocket guard (3).
(Fig. 26)
Turn chain tensioning screw (4) to the left (counter-clockwise)
until the pin (5) of the chain tensioner is underneath the
threaded pin (6).
(Fig. 27)
Put on the guide bar (7). Make sure that the pin (5) of the
chain tensioner engages in the hole in the guide bar.
(Fig. 28)
Lift the chain (9) over the sprocket (8).
Guide the chain from above about halfway into the groove
(10) on the guide bar.
CAUTION:
Note that the cutting edges along the top of the chain must
point in the direction of the arrow!
(Fig. 29)
Pull the chain (9) around the sprocket nose (11) of the guide
bar in the direction of the arrow.
(Fig. 30)
Replace the sprocket guard (3).
IMPORTANT:
Lift the saw chain over the chain catcher (12).
Tighten the nuts (2) only hand-tight to begin with.
6a-2. Tightening the saw chain (Fig. 31)
Turn the chain tensioning screw (4) to the right (clockwise)
until the saw chain catches in the groove on the lower side of
the guide bar (see circle).
Slightly lift the end of the guide bar and turn the chain
adjusting screw (4) to the right (clockwise) until the chain
rests against the bottom side of the guide bar.
While still holding up the tip of the guide bar, tighten the
retaining nuts (2) with the universal wrench.
6a-3. Checking the chain tension (Fig. 32)
The tension of the chain is correct if the chain rests against
the bottom side of the guide bar and can still be easily turned
by hand.
While doing so the chain brake must be released.
Check the chain tension frequently - new chains tend to get
longer during use!
When checking the chain tension the engine must be
switched off.
NOTE:
It is recommended to use 2-3 chains alternatively.
In order to guarantee uniform wear of the guide bar the bar
should be turned over whenever replacing the chain.
6a-4. Retightening the saw chain (Fig. 33)
Loosen the nuts (2) about one turn with the universal
wrench.
Raise the tip of the guide bar a little and turn the chain
tensioning screw (4) to the right (clockwise) until the saw
chain is again up against the bottom edge of the guide bar
(see circle).
While keeping the tip of the guide bar raised, tighten the nuts
(2) again with the universal wrench.
6b. Only for the QuickSet guide bar
CAUTION:
Before doing any work on the guide bar or chain, always
switch off the engine and pull the plug cap off the
spark plug (see “Replacing the spark plug”). Always wear
protective gloves!
CAUTION:
Start the chain saw only after having assembled it
completely and inspected.
