TRIMMER CHAINSAW AND CUTTER
CT529IN1GCKA

•For safety reasons, minors are not allowed to work with the trimmer, except
persons over 16 years of age who are trained under supervision.
•Operate the trimmer in good physical and mental condition. Do not use the device
in an ill or tired state or under the influence of any substances or medical
preparations that may affect vision, physical or mental condition.
•Work only during daytime or with good artificial light.
•Do not start working without preparing the work area. Carefully inspect the area of
the proposed mowing, remove foreign objects that may be thrown away by the
cutting unit or may be attached to it.
•It is not recommended to work with a trimmer alone. Make sure that when you are
working within hearing distance of another person in case you need help.
•Unauthorised people, children and animals should be kept at a safe distance
outside the work area. Do not allow others to come closer than 15m from a working
device. People at risk (near the work area) should wear safety glasses.
•Check the trimmer before operating to ensure that all the handles, mounts and
guards are in place and good condition.
•Work in tight and durable clothing that can protect any solid objects in the case of
a cutting node. Do not wear excessively wide clothing and jewellery, as they may
fall into the moving parts of the device. Wear sturdy protective gloves. Gloves not
only protect your hands from damage but also reduce the transmission of vibration
to your hands. Prolonged exposure to vibration may cause numbness of the fingers
and other conditions.
•Wear sturdy and reasonably tall shoes with non-slip soles for greater stability. To
avoid injuries with the possible discarding of foreign objects by the cutting unit, do
not work with the device barefoot or in open shoes.
•To avoid damage to your hearing, it is recommended to use ear protectors or
earplugs while working with the trimmer.
SAFETY & WARNINGS
WARNING: Do not work with a trimmer under the influence of alcohol
or drugs or after using strong medicines.
WARNING: Always use protective glasses or gloves when working. It is
highly probable that solid objects or fragments of mowed stiff
vegetation are dropped into the face and eyes.

•Perform tank refuelling outdoors on the ground. Close the fuel cap tightly. Do not
refuel indoors.
•Fuel is highly flammable and explosive. Do not smoke, do not allow the presence
of sparks and flames in the fuel storage area and when the engine fuelling. Do not
refuel a hot engine. Shut off the engine before refuelling and make sure that it is
cold. The fuel tank may be under pressure. Carefully loosen the fuel cap first to
release any possible pressure and then remove it.
•Do not work with the trimmer if fuel was spilled during refuelling. Before starting,
carefully wipe the surface of the engine from accidentally spilled fuel and wait until
the remaining fuel evaporates. If fuel has been spilled, move the trimmer at least
three meters from the place of refuelling before starting the engine. Do not start
the engine if there is a smell of fuel.
•Do not store the unit with fuel in the tank. Fuel leakage may cause a fire. Avoid
contact with fuel. Irritations of the skin, the mucous membrane of the eyes, upper
respiratory tract or allergic reactions are possible with individual intolerance.
Frequent contact with fuel can lead to acute inflammation and chronic eczema.
Never start the engine indoors or in poorly ventilated areas. Never inhale exhaust
fumes. Exhaust gases contain carbon monoxide, which is colourless and odourless
and is very poisonous. Carbon monoxide in the respiratory system can cause loss
of consciousness or death. Do not start the engine if a malfunction of the ignition
system causes breakdown and sparking.
•Before starting the engine, make sure that the working bodies of the trimmer are
not in contact with foreign objects. Keep your hands and feet away from the
trimmer during engine start and operation. When working, always stand firm on
the ground, do not lose balance.
•Hold the trimmer with two hands; never attempt to work with one hand. Always
keep the working handles so that your fingers form a ring. Never work without the
protective cover of the trim coil.
•Do not lift the cutter above the knee level, as objects being thrown may fall into
the face or eyes.
•Take special care when changing direction, and when working in cramped
conditions (confined space). When working, approach the obstacle closely, but
never direct the cutting device inside or through the barrier. Hitting a trimmer cord
in a wire fence or a nylon mesh fence can cause pieces of wire, nets, and trimmer
cord to be dropped at high speeds in different directions.
•Do not touch the hot muffler and the cooling fins of the engine cylinder, as this can
cause serious burns. Do not work with the trimmer if the cylinder fins and muffler
are dirty.
•All maintenance and repair work should be carried out with the engine off.
•Keep the cutting device clean. Remove wound grass, branches, and foreign
objects from the trim coil and the trimmer gearbox.
•Turn off the trimmer immediately if abnormal vibration and/or noise occur. This
can be the result of serious damage to parts or components of the device, such as
a flywheel, a clutch, a cutting device, or a failure to correctly attach parts. Do not
make changes to the design of the device.

Chain tension adjustment
The correct chain tension is extremely important, and it must be checked both before
starting work and periodically during operation. Take the time to adjust the chain, as this will
increase the performance of the saw and extend its service life.
The gear, tire, chain, and crankshaft wear out much faster if the chain is excessively sagging
or too tight. View Fig. 16, which shows the correct tension for the cold chain (A), warm chain
(B) and the chain whose tension you need to adjust (C).
Loosen the nuts securing the tire (protective cover together with the brake flap); turn the
adjusting screw (1) clockwise to tighten the chain. To decrease the chain tension, turn the
adjusting screw (1) counter-clockwise. Make sure that the chain is located on the entire
periphery of the tire. (Fig.17)
Fig. 16
WARNING: Always wear protective gloves when working with the chain.
WARNING: The new chain will sag quickly and requires tension after
5-8 cuttings. Over time, the interval between tensioning increases.
Fig. 17
WARNING: If the chain moves along the tire with difficulty or stops, it
means that it is over tightened. Tension should be loosened.

Refilling the oil tank:
1. Be sure to clean the surface around the oil tank cap for not getting dirt inside.
2. Unscrew the oil tank cap and fill the chainsaw oil (tank capacity 200ml).
3. Screw on the oil tank cap.
4. Before start working, check the oil supply: turn on the pruning shears and hold
them over a control place. Inadequate lubrication results in a white mark from
droplets of discharged oil.
Proper lubrication is necessary to reduce chain friction with the tire. The lack of lubrication of
the trimmer reduces productivity and reduces service life, causing rapid wear on the chain
and tire due to overheating. This trimmer is equipped with an automatic lubrication system
that provides the necessary amount of lubricant to the tire and chain. With increasing
engine speed, the oil supply to the tire also increases.
Working techniques
To avoid rupture of the bark and pinching of the tire when trimming thick branches, always
start by making a lightweight cut (1) on the underside. To do this, use a cutting edge and
pull it tangentially through the bottom of the branch. Then make a cross-section.
Facilitated incision. (Fig. 18)
If the branch diameter is more than 10cm, undercut firstly, (3) and cross-section in of total
cutting. Then cut to the end (4). Flat cutting of thick branches. (Fig. 18)
Fig. 18
Fig. 19
WARNING: Always check the oil level. Never operate the trimmer with
a lack of oil for chain lubrication.

Brush cutter installation
1. Make sure that the cutting insert is locked in the storage/transport position (tilted
back) and that the guard is mounted on the cutting inserts.
2. Connect the upper and lower part of the rod by turning it so that the spring button
of the lower part fits into the hole of the coupling in the upper part of the rod.
3. Use a screwdriver to make sure all screws are tightened correctly.

Fuel mixture preparation
For the preparation of the fuel mixture, petrol with an octane rating of no less than 92, and
special oil for two-stroke air-cooled engines shall be used. The recommended proportional
ratio of the petrol and fuel oil is 40:1, unless otherwise indicated on the label of the oil used.
Never use oil designed for 2-stroke water-cooled engines (boat motors).
Never use oil for 4-stroke engines. This can lead to the formation of carbon deposits on the
spark plug, contamination of the exhaust pipe outlet or damage to the piston rings.
For the preparation of the fuel mixture is recommended to use the capacity of the dispenser
supplied.
1. Pour half of the petrol prepared for operation into the container.
2. Add the required amount of engine oil.
3. Close the tank lid tightly.
4. Stir the fuel mixture thoroughly in the container.
5. Slowly open the tank lid to release air and then add the remaining petrol.
6. Close the container and shake well again.
OPERATION
WARNING: To prepare and store the fuel mixture, use special tanks
for petrol. Do not use food plastic containers. Never prepare the fuel
mixture directly in the fuel tank.
WARNING: To prepare the fuel mixture, use fresh high-quality petrol.
Carefully maintain the petrol/oil ratio. Never use clean petrol to refuel a
trimmer engine.
WARNING: Perform all work on the fuel outdoors or in a well-
ventilated area, away from sources of ignition.
WARNING: Ready-to-use fuel mixture is recommended for use within
30 days. During long-term storage, the fuel mixture oxidises, becomes
non-uniform and unsuitable for use.

Cold start
1. Fill the fuel mixture in the tank:
•Stop the engine and allow it to cool completely before refuelling.
•Fill the fuel tank in the open air in a well-ventilated area, away from sources of
possible ignition.
•Clean debris near fuel cap.
•Slowly unscrew the fuel cap.
•Carefully fill the fuel mixture.
•Do not completely fill the fuel tank; there must be room for fuel expansion.
•Screw the fuel cap on tight. Before starting, wipe the fuel tank dry of any
spilled fuel.
2. Before starting the engine, make sure that:
•The engine does not leak fuel.
•All fasteners are securely attached.
•The trim head or blade properly installed and secured.
•The protective cover is properly installed and securely fastened.
•The working handles are adjusted and securely fastened.
•The shoulder strap is properly installed and adjusted. Before starting work, it is
advisable to put on a belt and hang a trimmer on it without starting the
engine. This will allow you to easily adjust the belt in shape and height, adjust
the position of the cutting device relative to the ground surface.
WARNING: Before starting the engine, make sure that the working
part of the trimmer does not touch foreign objects.
WARNING: Hold the trimmer firmly so as not to lose control during
starting. Do not run the trimmer in the air or with a belt. If you lose
control, the device may strike your leg or an obstacle.
