SAFETY INSTRUCTIONS
Safety instructions and accident prevention.
To prevent the incorrect handling of the chainsaw,
please read the operating instructions in their entirety
before using the chainsaw for the first time.
All the information on the handling of the chainsaw is
relevant to your personal safety. Ask a professional to
show you how to use the chainsaw!
• Before plugging in, check the plug and cable for dam-
age. If damage is discovered, have it repaired by a
specialist immediately.
• Never use a damaged cable, connection or plug or a
power cable which does not comply with the require-
ments. If the cable is damaged or severed unplug
immediately.
• Switch the chainsaw off before releasing the chain
brake.
• Always wear goggles and protective gloves when
working with the chainsaw.
• To prevent injury, wear tight-fitting clothes and safety
boots.
• To prevent damage to your hearing, wear earmuffs,
helmets with a visor are particularly advantageous.
• Make sure you have a firm footing when working
with the chainsaw.
• Keep your place of work tidy.
• To prevent electric shock, avoid contact with earthed
parts.
• Always pull the plug out of the power socket before
doing any work on the chainsaw.
• Only plug in when the chainsaw is switched off.
• The chainsaw must be used only by one person
at a time. All other persons must stay clear of the
chainsaw’s area of swing. Children and pets in
particular must be kept away at all times.
• The saw must not be touching anything when
it starts up.
• Hold the chainsaw firmly in both hands when
working with it.
• The chainsaw must not be operated by children
and young people. The only exception to this
prohibition are young persons of 16 years and over
who can use the chainsaw under supervision as part
of their training. Lend the saw only to those persons
who are familiar with this type of chainsaw and know
how to handle it.
Always pass on the operating instructions together
with the chainsaw.
• Make sure the chains saw is stored in a place
inaccessible to children.
• The saw may be operated only by persons who are
rested and in good health, i.e. in a good physical
condition. If you start to tire, have a rest break. The
chainsaw should not be used after the consumption
of alcohol.
• Never expose the chainsaw to rain or bad weather.
Make sure there is enough light at the place of work.
Do not use power tools in the vicinity of combustible
liquids or gases.
• If the chainsaw is not being used for a while, it must
be set aside in such a way that no other person is
endangered.
• Never use the chainsaw when standing on a ladder
in a tree or in any other unstable places. Do not saw
with one hand.
• The power cable must always lead away from the
rear of the chainsaw.
• Use only original accessories.
• Chainsaws used outdoors must be connected up to
an earth-leakage circuit-breaker.
• Do not overload your power tools. They run best and
safest within the given range of capacity.
• Always use the correct power tool. Do not use low-
powered chainsaws for heavy jobs.
SAFETY

• Never use the chainsaw if it has a defective
ON/OFF-switch.
• Use the cable only for its proper purpose. Never
carry your electric tool by its cable. Do not use the
cable to pull the plug out of the socket. Protect the
cable from heat, oil and sharp edges.
• Use only authorised and accordingly labelled exten-
sion cables. Use a strong support when sawing
converted timber and thin branches (saw-horses, see
fig.7b). Do not stack the timber and do not have it
held by a second person or with your foot.
• Logs must be secured in position.
• On sloping ground, always work facing upwards.
• Always set the claw stop (II) against the timber before
switching on the chainsaw (See fig.7b). Pull the
chainsaw upwards at the rear and lead the direction
with the front grip. Use the claw stop as a fulcrum.
To reposition for further cutting, interrupt the sawing
process and exert a slight pressure on the front
grip. Pull the saw back a little, position the claw stop
further down the cut and pull up the rear grip (See
fig.7a).
• Pull the saw out of the wood only when the saw
chain is running.
• If you carry out several cuts, switch off the chainsaw
in-between.
• Plunge cuts and horizontal cuts may only be carried
out by professionals (high risk of kickback , see Fig.8)
• For horizontal cuts, position the smallest possible
angle. This requires extreme caution, as the claw stop
cannot be applied in this case.
• If the chain gets stuck when sawing with the upper
side it may be thrust towards the operator. For this
reason you should saw wherever possible with the
bottom side, as the chainsaw will then be thrust away
from the body towards the wood (See fig.9 and 10).
• Pay extra attention when cutting splintered wood.
Sawed off pieces of wood may be catapulted in any
direction (risk of injury!).
• When lopping branches, the chainsaw should be
supported wherever possible against the trunk. Do
not cut with the tip of the guide bar (risk of kick-back,
see Fig.8)
• Branch lopping work should be carried out by trained
personnel! Risk of injury!
• Pay special attention to branches under tension. Do
not cut through freely suspended branches from
underneath.
• Never stand on the a fallen tree when lopping off
branches.
• The chainsaw should not be used for forest work,
i.e. for felling and lopping off branches in the forest.
Because of the cable connection the saw operator
does not have the necessary mobility and his safety
is not guaranteed!
• Always stand to the side of the tree being felled.
• When the tree is being felled, watch out for falling
branches when stepping back.
• Watch out for trunks rolling towards you.
KICK-BACK!
• The chainsaw is likely to recoil if the tip of the guide
bar (especially the top guarter) accidentally touches
wood or any other solid objects. In this case the
chain saw will move uncontrollably and will be
kicked-back towards the operator at full power (risk
of injury!)
In order to prevent kick-back, please follow these
safety instructions:
• Never start cutting with the tip of the guide bar!
• Be careful, when continuing cuts you are already
working on!
• Always start cuts with the chainsaw 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.
• When cross-cutting, pay attention to trunks standing
very close to each other. If possible use a saw-horse.
SAFETY

TRANSPORTING THE CHAINSAW
Before transporting the chainsaw, always remove
the plug from the power socket and slide the chain
guard over the rail and chain. If several cuts are to be
performed with the chainsaw, the chainsaw must be
switched off between cuts.
BEFORE STARTING UP
The voltage and current supply must comply with the
ratings on the type plate. Before commencing work,
always check that the chainsaw works properly and
is safe to operate. Check also that the chain lubrica-
tion and the oil gauge are in good working order (See
fig.4). When the oil lever is approx. 5mm from the
bottom mark, you must top up with oil. When the oil
level is above this mark you can begin work.
Attach the power cord to the wire holder (18) by loop-
ing it as shown in (See fig.6). This will prevent the cord
from coming unplugged.
Switch on the chainsaw and hold it above the ground.
Do not allow the chainsaw to touch the ground. For
safety reasons it is best to keep a clearance of at least
20 cm. If you now see growing traces of oil, the chain
lubrication system is working correctly. If there are
no traces of oil at all, try cleaning the oil outlet (See
fig.2,C) the upper chain tensioning borehole (E) and
the oil duct , or contact your local Osaki agent (Be sure
to read the section “Filling up with chain oil and chain
lubrication” on this point). Check the chain tension
and retention if necessary (see the section “Tension-
ing the saw chain” on this point). Make sure the chain
brake is working properly (see the section “Releasing
the chain brake”.
ASSEMBLING THE GUIDE BAR AND SAW CHAIN
(See fig.1.2.3)
The chainsaw must be unplugged. Important: The
front finger guard (4) must always be in the top (verti-
cal) position (See fig.5)
The guide bar and saw chain are supplied separately.
To assemble, first unscrew the lock nut (6) and remove
the guide bar cover (7). The chain tensioning bolt
(21) must be in the centre of the guide. If necessary,
adjust the chain tensioning bolt with the screw (17). To
prevent injury on the sharp cutting edges, always wear
gloves when assembling, tensioning and checking the
chain. Before assembling the guide bar with the saw
chain, check the cutting direction of the teeth! The run-
ning direction is marked with an arrow on the cover (7)
(See fig.3, G.) To determine the direction of cut, it may
be necessary to turn over the saw chain (5).
Hold the guide bar (8) vertically with the tip pointing
upwards and put on the saw chain (5), beginning at
the tip of the bar.
THEN ASSEMBLE THE GUIDE BAR WITH THE SAW
CHAIN AS FOLLOWS: (See fig.3)
Place the guide bar with the saw chain on the guide
bolt (20) and chain tensioning bolt (21).
Place the saw chain round the chain wheel (19) and
make sure it is correctly mounted (See fig.1,A)
Place the cover (7) on top and tighten gently with the
lock nut (6) the supplied wrench. Now the saw chain
has to be correctly tensioned.
TENSIONING THE SAW CHAIN
Always pull the plug out of the power socket before
doing any work on the chainsaw.
Wear safety gloves!
Make sure the saw chain (5) is inside the guide groove
of the guide bar (8) (See fig.1 a). Using the supplied
hex key, turn the chain until it is correctly tensioned.
While the bolt (21) is being tightened, the guide bar
must then be pushed upwards. Check the chain ten-
sion again (See fig.3) Do not tension the chain too
tightly. When cold, it should be possible to lift the
chain in the middle of the guide bar approx. 5mm.
Tighten the lock nut (6) securely.
When warm, the saw chain will expand and slacken
and there is a danger of it jumping off the rail alto-
gether. Re-tension if necessary. If the saw chain is re-
tensioned when hot, it must be loosened again when
the sawing work has been completed. Otherwise, the
contraction which takes place as the chain cools will
result in excessively high tension.
A new saw chain requires a running-in period of ap-
prox. 5 minutes. Chain lubrication is very important
at this stage. After running in, check chain tension and
re-tension if necessary.
FILLING UP WITH CHAIN OIL (See fig.4)
To prevent dirt getting inside the tank, clean the oil
tank cap (15) before opening. Check the contents of
the oil tank during sawing work by checking the oil
gauge (16). Close the oil tank cap tightly and wipe
away any spills.
ASSEMBLY

CHAIN LUBRICATION
To prevent excessive wear, the saw chain and guide
bar must be evenly lubricated during operation.
Lubrication is automatic. Never work without chain
lubrication. If the chain runs dry, the entire cutting
apparatus will quickly become severely damaged. It is
therefore important to check both chain lubrication and
the oil gauge before use (See fig.4).
Never use the chainsaw when the oil level is below the
“Min” mark.
• Min.: When only approx. 5mm of oil is visible at
the lower rim of the oil gauge (16), you must
top up with oil.
• Max.: Top up with oil until the window is full.
CHECKING THE AUTOMATIC LUBRICATION
Before commencing work, check the automatic chain
lubrication and oil gauge. Switch on the chainsaw and
hold it above the ground. Be careful not to allow the
chainsaw to touch the ground. For safety reasons it is
best to keep a clearance of at least 20cm. If you now
see growing traces of oil, the chain lubrication system
is working correctly. If there are no traces of oil at all,
try cleaning the oil outlet (See fig.2 C), the upper chain
tensioning borehole (E) and the oil duct, or contact
your lokal Osaki agent. Check the oil level every 15
minutes during the operation.
Clean the area around the oil tank cap (15) carefully
before taking off to avoid dirt entering into the oil tank
throughout the outlet (See fig.4.21).
CHAIN LUBRICANTS
The service life of saw chains and guide bars depends
to a large extent on the quality of the lubricant used.
Old oil must not be used! Use only environmentally
- friendly chain lubricant. Store chain lubricant only in
containers which comply with the regulations.
GUIDE BAR
The guide bar (8) is subjected to especially severe
wear and tear at the nose and the bottom. To avoid
one-sided wear and tear, turn the guide bar over every
time when you sharpen the chain.
CHAIN GUARD
The chain guard must be clipped onto the chain and
bar as soon as the sawing work has been completed
and whenever the chainsaw has to be transported
CHAIN BRAKE
In the event of kick-back, the chain brake (4) will be
actuated via the front finger guard. The front finger
guard is pushed forward by the back of the hand and
this causes the chain brake to stop the chainsaw, or
rather the motor, within 0.15 seconds (See fig. 5.I)
RELEASING THE CHAIN BRAKE (FIG. 5)
To be able to use your chainsaw again. First switch
off the chainsaw. Then push the front finger guard
(4) back into the vertical position until it locks in place
(See fig.5, H) The chain brake is now fully functional
again.
SHARPENING THE SAW CHAIN
You can have your saw chain sharpened fast and
correctly by specialist dealers, from whom you can
also obtain chain sharpening equipment to enable
you to sharpen the chain yourself. Please follow the
corresponding operating instructions.
STARTING UP
Always wear safety goggles, ear muffs, protective
gloves and heavy-duty work clothes!
Use the saw only with approved extension cables with
the prescribed insulation and connections designed
for outdoor use (approved rubber-sheathed cables)
which fit the chainsaw plug. The chainsaw is equipped
with a two-handed safety switch. The chainsaw works
only when one hand holds the front grip (3) and the
other hand actuates the switch on the rear grip (1).
If the chainsaw does not run, the chain brake must be
released at the front finger guard (4). Be sure to read
the sections “Chain brake” and “Releasing the chain
brake” on this point.

• After switching on, the chainsaw will run immediately
at high speed. To switch off:
Release either the ON/OFF switch (14) on the rear grip
or the other switch (2) on the front grip.
The release of the ON/OFF will result in the chainsaw
stopping within 1 sec.
• After working with the chainsaw, you should always:
Clean the saw and guide bar and replace the chain-
guard.
CHAINSAW PROTECTION
• Never use the chainsaw in the rain or in damp condi-
tions.
• If the extension cable is damaged switch the mains
power off and 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 work-
ing 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 chain-
saw 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 operat-
ing instructions.
NOTES ON WORKING PRACTICE
KICK-BACK (See fig.8)
• 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 therefore increases the chances of the chain
becoming slack or blunt. A poorly sharpened chain
increases the risk of kick-back. Never saw above
shoulder height.
TIPS ON CHAINSAW USE
SAWING UP WOOD (See fig.7A,7B)
To saw up wood, please observe the safety regulations
and proceed as follows:
• Make sure the wood to be sawed cannot slip.
• Clamp short pieces of wood in place before sawing.
• Saw only wood or wooden objects.
• When sawing, make sure that no stones or nails are
touched as these could be thrown out and damage
the saw chain.
• Avoid bringing the running saw into contact with
wire fences or the ground.
• When lopping off branches, support the chainsaw
as far as possible and do not saw with the tip of the
guide bar.
• Watch out for obstacles such as tree stumps, roots,
ditches and hillocks as these could cause you to fall.
REMEMBER:
The chainsaw must be running before it comes
into contact with the wood. To switch on:
• Press the safety lock-off (12) and ON/OFF switch
on (14).
• Place the lowest claw stop(See fig.4,J) on the wood.
• Raise the chainsaw by the front grip (3) and saw into
the wood.
• Move the chainsaw back a little and place the claw
stop further down. Be careful when sawing splin-
tered wood as pieces of wood may be ripped off.

KICK-BACK

KICK-BACK
THE NUMBERS MENTIONED IN THE TEXT CORRESPOND WITH THE PICTURES

FELLING TREES
To fell trees, observe all the safety regulations and
proceed as follows:
If the saw chain gets jammed, release it using a wooden
wedge.
REMEMBER:
DANGER ZONE: Falling trees can bring down other trees
with them. The danger zone is therefore twice the length
of the tree being felled (See fig.12).
• Felling trees is dangerous and requires practice. If you
are a beginner or inexperienced, do not try to teach
yourself but seek professional training.
FALLING DIRECTION (See fig.13):
• First estimate the direction of fall, taking into account
the centre of gravity of the crown and the wind direc-
tion. The chainsaw must be running before is comes
into contact with the wood. Switch on the chainsaw.
Always plan an escape route to a safe location from
where you are working.
Place the chainsaw on the ground and do not run with
it switched on or off.
• Cut a “felling notch” perpendicular to the line of fall,
close to the ground. Cut the bottom of the notch first,
horizontally and about one third of the way through the
diameter. The second cut is made at a 45 degree angle
that will meet the depth of the first cut. Remove the
“felling notch”.
• Only now make the “felling cut” on the opposite side
of the “felling notch”.
• Begin 1 or 2 inches higher than the centre of the “fell-
ing notch” and cut horizontally towards it. Do not cut
all the way through but leave a hinge that will keep the
tree from kicking back and upward as it falls. The hinge
will be about 1/8 to 1/6 of the diameter where you are
cutting but it may vary, depending on when the tree
starts to fall.
• Now call “TIMBER!” and leave on your planned escape
route. Do not return to the site until the tree is down
and no longer moving.
• If the tree fails to fall, drive non-metallic wedges into
the “felling cut” where necessary to control the fall.
DO NOT FELL TREES:
• If you can no longer distinguish details within the
danger zone, e.g. owing to fog. rain, snow drifts or
twilights.
• If the direction of fall cannot be reliably estimated ow-
ing to wind or gusts of wind.
Felling work on sloping ground, black ice, frozen or
dewy ground is safe only if you can get a firm foothold.
• To switch off: Pull the plug out of the power socket.
MAINTENANCE AND CLEANING
Always pull the plug out of the power socket before do-
ing any work on the chainsaw!
Keep the cooling vents on the motor housing clean and
unobstructed at all times. Only the maintenance work
described in these operating instructions may be carried
out.
Any other maintenance work must be carried out by
the Osaki repair and service facility. Do not modify the
chainsaw in any way as this could jeopardise its safety.
Should the chainsaw fail despite our careful manufac-
turing and inspection procedures, have it repaired by
the Osaki repair and service facility. In the event of any
inquiries and spare parts orders, always quote the type,
model and the part number.
STORAGE
Keep your chainsaw in a safe place. The unused chain-
saw should be stored clean, on a flat surface and in a
dry place which is inaccessible to children.
ENVIRONMENT
Should your machine need replacement after extended
use, do not put it in the domestic waste but dispose of
it in an environmentally safe way.
