Avoid accidental starting of the chainsaw. When handling the chainsaw connected to the mains or with the battery connected,
keep your fi ngers 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 e ffi cient 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 fi nding 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. Disconnect the
mains-powered chainsaws from the socket. In the case of the battery-powered chainsaws, disconnect their battery.
Mount the guide bar and cutting chain before fi rst use.
Due to the sharp edges of the chain, perform the assembly wearing protective gloves.
Turn the locking knob in the direction indicated by the arrow marked with the open padlock symbol and remove the side panel.
Mount the guide bar and chain as shown in picture (II). Make sure that the chain and guide bar are fi tted in the correct direction.
The shape and direction of the links visible on the chainsaw housing should correspond to the chain’s shape and direction. 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.
Ensure that the chain hits the guide slot and the teeth on the sprocket. Install the side panel and turn the locking knob in the direc-
tion indicated by the arrow marked with the closed padlock symbol (II). This will fi x the side panel and tension the chain. 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 too tight or too weak, turn the locking knob
in the direction indicated by the arrow marked with a closed padlock symbol. The chain tension should also be checked every 10
minutes of operation. Check the technical condition of the power saw before connecting it to the power supply. If any damage is
detected, it is forbidden to connect it to the power supply before rectifying 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 battery.
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 ful fi l 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
performed. Perform oil topping-up away from fi re and heat sources.
To top up the oil, unscrew the oil tank cap, pour the oil inside the tank so the oil level levels out with a mark indicating the maximum
oil level or upper edge of the oil level indicator, then screw the tank cap fi rmly and securely. In case of spilling the oil, thoroughly
wash o ff any debris before connecting the chainsaw to the power supply.
Connecting the chainsaw to the power supply
The machine is supplied only with a short power cord. Use an extension cord for proper power supply. The extension cord should
have rubber insulation of at least the H05RNF type or polyvinyl (PVC) insulation of at least the H05VVF type.
Always use cords intended for outdoor use due to the nature of the machine work. The power cord should have a single socket
matching the machine’s plug. It is forbidden to modify the plug or socket to make them fi t. The electrical parameters of the power
supply cord should correspond to the electrical parameters of the tool, listed on the rating plate. It should be noted that the power
