Avoid contact with grounded, conductive, and non-insulated objects such as pipes,
radiators or refrigerators. When not in use, store the chainsaw in a dry and closed room inaccessible to unauthorised persons.
Use the cutting chain adapted to the given load. Do not use cutting chains designed for light or heavy-duty work.
Always wear protective gloves when replacing, repairing, and adjusting the cutting chain.
Make sure that the chainsaw has been disconnected from the power supply during transport. Disconnect the mains-powered
chainsaws from the socket. In the case of the battery-powered chainsaws, disconnect their battery. A guard must be fitted on the
cutting chain guide bar. Handle the chainsaw with the guide bar pointing back.
Do not handle the mains-powered chainsaw by its power cord. Do not disconnect the plug from the socket by pulling the power
cord.
Avoid accidental starting of the chainsaw. When handling the chainsaw connected to the mains or with the battery connected,
keep your fingers away from the power switch.
Always wear suitable protective clothing adhering to the body.
Operate the chainsaw holding it with both hands. When working, secure loose pieces of wood so that they cannot move, for ex-
ample, by placing them in a saw-horse. Avoid cutting wood that lays on the ground. Avoid processing wood that is not protected
against movement during cutting.
Do not hold the chainsaw above your arms during operation. Do not operate the chainsaw while standing on the ladder. During
work, adopt such a posture to eliminate the need to extend the hands to the full length.
Keep the chain clean. The chain must be sharpened and lubricated. This will ensure more efficient and safer work. The chain can
be sharpened in a specialised service centre. Check the condition of the chain before each use. In the event of cracks, broken
teeth, or any other damage, replace the chain with a new one before starting work.
In case of finding any damaged or broken chainsaw parts, stop working or do not start working. It is essential to replace damaged
parts before starting work.
Use the chainsaw as intended. The chainsaw is designed only for cutting wood. When working, watch out for metal elements or
stones that may be in the processed wood.
Use original spare parts only. Failure to use original spare parts may increase the risk of failure and lead to injuries.
The chainsaw should be repaired only in service centres authorised by the manufacturer using original spare parts. This will
minimise the risk of accidents and damage to the equipment.
PRODUCT OPERATION
Preparing the chainsaw for operation
Caution! Unplug the chainsaw from the power supply before performing any assembly and adjustment work. Remove the battery
from the device.
Mount the guide bar and cutting chain before first use.
Remove the side panel locking bolt, then turn the tension knob until the panel can be detached from the chainsaw.
Mount the guide bar and chain as shown in the picture (II).
Make sure that the chain and guide bar are fitted in the correct direction. The shape and direction of the links visible on the chain-
saw housing should correspond to the shape and direction of the chain. If there is a visible movement direction indication on the
chain links, it should have the same direction as the indication on the housing and guide bar.
Do not tension the chain yet, but make sure that the chain fits the guide bar slot and the teeth on the drive wheel. Mount the side
panel and tighten the locking knob. However, do it so as not to block the possibility of the guide bar movement. Adjust the chain
tension by turning the chain tension knob. The tensioning cam tooth must rest on the slot of the guide mounting (II). This is the
only way to move the guide forward and tension the chain.
Screw in the locking bolt. Check the chain tension. To do this, set the chainsaw down and lift it by holding the middle part of the
chain (III). During this test, the chain should lift above the guide bar by 3 to 4 mm in the spot where it is held. If the chain is tight-
ened too tight or too loose, loosen the locking knob a little and reset the chain tension level. The chain tension level should also
be checked every 10 minutes of operation.
Check the technical condition of the chainsaw before connecting it to the power supply. If any damage is detected, it is forbidden
to connect it to the power supply before removing the damage.
Oil topping-up (IV)
Caution! Unplug the chainsaw from the power supply before performing any assembly and adjustment work. Disconnect the
mains-powered chainsaws from the socket. In the case of the battery-powered chainsaws, disconnect their batteries.
For lubricating the chain and chainsaw mechanisms, use only oil intended for such purposes. It is forbidden to use worn-out motor
oil. It does not fulfil its purpose, which can lead to damage to the chainsaw mechanism.
Make sure that there is lubricating oil in the tank. Place the chainsaw on the horizontal surface and check the oil indicator. The oil
level cannot be lower than the minimum indication. If there is no such indicator, the lower edge of the oil level indicator should be
taken as the reference level.
It is forbidden to use the chainsaw with the empty oil tank. This can damage the chain, guide bar, and mechanisms of the chain-
saw. It is recommended to start and operate the chainsaw at least 3 meters from the place where the oil topping-up procedure was
