• During recoil the chainsaw cannot be controlled and the chain is
loosened.
• An incorrectly sharpened chain increases the risk of recoil.
• Do not cut above the level of your shoulders.
Avoid cutting with the guide bar tip, since it may cause sudden
recoil – to the back and up. Always use complete safety
equipment and appropriate working clothes when operating
the chain saw.
Disassembly of safety devices, inappropriate operation,
maintenance, improper guide bar or chain replacement may
contribute to the increase of the risk of body injuries in case of
a recoil. Never modify the chainsaw in any way. The guarantee
rights are voided, should a modified chain saw is used. The
guarantee is also voided, when the chainsaw is not used
according to instructions contained in this manual.
TRIMMING / CUTTING TREE BRANCHES AND BUSHES
Start cutting branches of a felled tree at its base and continue
towards the top of the tree. Small twigs should be cut at one go.
First, check which way the branch bends. Then, make a cut from the
inside of the bend and finish cutting on the opposite side. Be careful,
the branch being cut may spring back.
When trimming tree branches, always cut downward to enable free
fall of a cut branch. However, sometimes undercutting the branch
from the bottom may be helpful (branches of not more than 10 cm
in diameter).
Be very careful when cutting a branch that may be strained. Such a
branch may spring back and hit the operator. Examples of how the
chainsaw can be used are shown in the fig. T
Do not cut branches when climbing up the tree. Do not stand
on ladder, platforms, logs or positions that may cause loss of
balance and control over the chainsaw. Do not cut above the
level of your shoulders. The chainsaw should be held with both
hands at all times.
OPERATION / SETTINGS
PREPARATION OF FUEL MIX
The multi-function garden tool is powered by a petrol and oil
mix in 25:1 ratio.
Most of the problems with combustion engines is indirectly or
directly related to used fuel. Special attention should be paid
not to use engine oil intended for four-stroke engines. Never
mix petrol and oil directly in the tool fuel tank. Always mix fuel
and oil in a canister intended for that purpose.
According to the below table, mix petrol (lead-free with the octane
number of 95) with good quality engine oil for two-stroke engines.

FILLING THE FUEL TANK
When filling with fuel, the following rules should be observed:
– the engine must not work,
– fuel cannot be spilled.
• Unscrew the fuel filler plug (2).
• Pour in previously prepared fuel mix (max. 600 ml).
• Screw the fuel filler plug (2).
STARTING THE ENGINE
Under no circumstances do not start the engine without the
cutting element guard in place. Using improper or damaged
guards may lead to serious injuries.

An incorrectly wound cutting string or improper cutting tools
may increase vibrations.
The tool is equipped with the switch preventing from accidental
activation of the tool.
Switching on – Move the ignition switch (8) (fig. U) to the position "I",
the choke lever (42) (fig. W) to the upper position and energetically
pull the starter rope handle (44). If the engine fails to start after a
number of attempts, pump some fuel using the membrane pump
(49) (fig. X) and try again. Once the engine is started, you can begin
to operate the chainsaw only after a couple of seconds gradually
switching off the choke by sliding the choke lever downwards until
the throttle is fully opened (see marking on the air filter housing).
In order to increase the engine speed, press the lock button of the
throttle lever (6) and press the throttle lever (7).
Switching off – release the pressure on the throttle lever (7). Move
the ignition switch (8) to the position "stop" "O".
The cutting elements keep rotating for some time, after the
motor is switched off. Do not use the tool, while it rains or in
wet areas. Never work with a damaged tool. All parts should be
correctly assembled and fulfil requirements ensuring proper
and safe operation of the tool. Any damaged protective element
or other part should be immediately repaired or replaced.
ADJUSTING THE IDLE SPEED
The engine idle speed should be selected so that the engine does
not stall and the cutting element does not rotate. If the speed is
too high or too slow and the cutting element rotates although
the throttle lever is in the idle speed position, the engine idle
speed should be adjusted.
• Locate the idle speed adjustment bolt (47) behind the air filter
housing (4) (fig. W).
• Start up the engine. Rotate the idle speed adjustment bolt using
a screwdriver (clockwise to increase the speed and counter-
clockwise to decrease the speed).
The engine is hot during operation and as soon as it it switched
off. Do not touch, because you may get burnt.
Combustion gases contain carbon dioxide, which can be
poisonous when inhaled. Therefore, it is forbidden to start up
the engine in closed rooms and in places with poor ventilation
or near inflammable materials.
OPERATION AND MAINTENANCE
Ensure the engine is switched off and is cold before cleaning,
checking or repairing the chainsaw. Disconnect the wire from
the sparking plug to prevent accidental start up of the engine.
STORAGE
• Empty the fuel system before the tool is stored for more than one
month.
• Drain fuel from the fuel tank, start the engine and allow it to use all
remaining fuel and stop working.
• Use fresh fuel each season. Never use any cleaning agents to clean
the inside of the fuel tank, it may damage the engine.
• Pay special attention to keep the ventilation holes of the engine
casing passable.
• Clean plastic parts with mild detergent and a sponge.
• Never clean the tool with water, aggressive fluids or solvents.
• You can proceed with maintenance activities only described in
this instruction manual. Any other activities can be carried out
only by an authorized service workshop.
• Periodically check the condition of the sparking plug of the
combustion engine. A used sparking plug should be replaced with
a plug recommended by the manufacturer.
• Do not make any changes in the chainsaw construction.
• When not in use, the chain saw should be stored in clean condition,
on a flat surface, in a dry place and out of reach of children.
When storing it is important to avoid deposition of rubber
particles in basic components of the fuel system, such as
carburettor, fuel filter, fuel line and fuel tank. Fuels with alcohol
