depending on its class:
- Professional and mid-class: Use on small, medium
and large trees: felling, limb removal, cutting to length,
thinning.
- Hobbyklasse: Occasional use on small trees, fruit‑tree
care, felling, limb removal, cutting to length.
Unauthorised 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.
3-2. General precautions
‑ To ensure correct operation the user has to read this
instruction manual (Fig. 2) to make himself familiar
with the characteristics of the petrol pruning saw. Users
insufciently informed will endanger themselves as well as
others due to improper handling.
‑ It is recommended to lend the petrol pruning saw only to
people who are experienced in working with petrol pruning
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 petrol pruning saw. Persons
over the age of 16 years may, however, use the petrol
pruning saw for the purpose of being trained as long as
they are under the supervision of a qualied trainer.
‑ Use petrol pruning saws always with the utmost care and
attention.
‑ Operate the petrol pruning 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 petrol pruning 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 petrol pruning 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 petrol pruning 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 petrol pruning 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 brand analysis 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 22 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 petrol pruning saw.
‑ During operation of the petrol pruning 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.
3-4. Fuels / Refuelling
‑ Stop the engine before refuelling the petrol pruning 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 petrol pruning saw. Fuel should not
come in contact with clothes. If your clothes have come in
contact with fuel, change them ot 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 petrol pruning 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 petrol pruning saw only into operation if it is
completely assembled. Never use the petrol pruning saw
3. SAFETY PRECAUTIONS

17
when it is not completely assembled.
‑ Before starting the petrol pruning saw ensure that you
have a safe footing.
‑ Put the petrol pruning saw into operation only as
described in this instruction manual (Fig. 9). Other starting
methods are not allowed.
‑ When starting the petrol pruning 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 petrol pruning 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 petrol pruning saw such that you will not breathe
in the exhaust gas. Do not work in closed rooms (danger
of poisoning).
‑ Switch off the petrol pruning 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.
‑ When stopping work or leaving the working place switch
off the petrol pruning saw (Fig. 10) and put it down such
that nobody is endangered.
● Maintenance
● Refuelling
● Sharpening the chain
● Stopping work
● Transport
● Putting out of function
CAUTION: Do not put the overheated power petrol
pruning 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 petrol pruning 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 petrol pruning 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 petrol
pruning saw.
‑ Do not work leaning too far over.
‑ Guide the petrol pruning saw in such a way that no part of
your body is within the elongated swivelling range of the
saw (Fig. 13).
‑ Use the petrol pruning saw for sawing wood only.
‑ Avoid touching the ground with the petrol pruning saw
while it is still running.
‑ Never use the petrol pruning 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 petrol pruning saw is lifted at the
back handle and guided with the tubular handle. The spike
bar serves as a center of rotation. Continue by slightly
pressing down the tubular handle and simultaneously
pulling back the petrol pruning 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).
‑ 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 petrol
pruning 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
petrol pruning 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 petrol
pruning 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.
CAUTION:
People felling trees or cutting of branches must be
specially trained. High risk of injuries!

18
‑ When cutting of branches, the petrol pruning 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
only those people are within the working area whicha.
are actually involved in cutting down the tree.
every worker involved can withdraw without stumblingb.
(the people should withdraw backwards in a diagonal
line, i. e. at a degree of 45°).
the bottom part of the trunk is free from foreignc.
objects, underbrush and branches. Make sure to have
a safe footing (risk of stumbling).
the next working place is at least 2 1/2 tree lengthsd.
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.
‑ 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 petrol
pruning 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 petrol pruning saw and actuate the chain brake in
order to prevent an inadvertent start of the chain.
‑ Never carry or transport the petrol pruning 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 petrol pruning saw over long
distances the guide bar protection cover (delivered with
the petrol pruning saw) must be applied.
‑ Carry the petrol pruning 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 petrol pruning saw during
car transportation to avoid fuel or chain oil leakage.
‑ Store the petrol pruning saw safely in a dry place. It must
not be stored outdoors. Keep the petrol pruning saw away
from children.
‑ Before storing the petrol pruning 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
petrol pruning saw (Fig. 22) and pull out the plug cap.
‑ Before starting work always check the operating safety
of the petrol pruning saw, in particular the function of
the chain brake. Make sure that the chain is always
sharpened and tightened correctly (Fig. 23).
‑ Operate the petrol pruning saw only at a low noise and
emission level. For this ensure the carburetor is adjusted
correctly.
‑ Regularly clean the petrol pruning 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 petrol pruning
saw. You will put your safety at risk.
Perform only the maintenance and repair works described
in the instruction manual. All other work must be carried
out by MAKITA Service.
Use only original MAKITA spare parts and accessories.
Using spare parts other than original MAKITA parts or
accesories and guide bar/chain combinations or lengths
which are not approved bring a high risk of accidents.
We cannot accept any responsibility for accidents
and damage resulting from using sawing devices or
accesories which have not been approved.
3-10. First aid
For the event of a possible accident, please make sure
that a rst aid kit is always immediately available close by.
Immediately replace any items used from the rst aid box.
When calling for help, give the following information:
‑ Place of the accident
‑ What happened
‑ Number of injured people
‑ Kind of injuries
‑ Your name!
NOTE
Individuals with poor circulation who are exposed to
excessive vibration may experience injury to blood vessels or
the nervous system.
Vibration may cause the following symptoms to occur in the
ngers, hands or wrists: “Falling asleep” (numbness), tingling,
pain, stabbing sensation, alteration of skin colour or of the
skin.
If any of these symptoms occur, see a physician!

always switch off the engine and pull the plug cap
off the spark plug (see 8-6 “Replacing the spark
plug”). Always wear protective gloves!
CAUTION:
Start the petrol pruning saw only after having
assembled it completely and inspected.
7a-1. Mounting the guide bar and saw chain
(Fig. 25)
Use the universal wrench delivered with the petrol pruning
saw for the following work.
Put the petrol pruning saw on a stable surface and carry out
the following steps for mounting the guide bar and saw chain:
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).
CAUTION:
Do not insert the chain between the chain sprocket and the
disc.
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.
7a-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.
7a-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.
