oil intended for four-stroke engines. Before refuelling, lay the chainsaw down so that the fuel filler is facing upwards. The use of
funnels, pouring devices etc. is recommended to reduce the risk of fuel spillage when filling the tank. In case of spilling the fuel,
thoroughly wipe off its residues before starting the chainsaw.
Topping up chain lubrication oil (VI)
Use a good quality oil designed for chainsaw chain lubrication.
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.
Switch off the chainsaw before refilling the oil.
It is recommended to start and operate the chainsaw at least 3 meters from the place where the oil topping-up procedure was
performed. It is forbidden to use worn-out motor oil. It does not fulfil its purpose, which can lead to damage to the chainsaw
mechanism.
Perform oil topping-up away from fire and heat sources.
In case of spilling the oil, thoroughly wash off any debris before connecting the chainsaw to the power supply.
You can regulate the amount of oil the chainsaw lubricates the chain, using the oil metering knob on the underside of the chainsaw.
Preparing the workplace
Before cutting with the chainsaw, properly prepare the workplace to minimise the risks associated with the chainsaw's operation.
Make sure that only authorised persons are present at the workplace.
In the case of tree felling, danger zones and escape routes should be designated. A zone with a radius of 180
around the planned
O
tree fall plane and a zone with a radius of 90
in the opposite direction to the planned tree fall plane are treated as danger zones.
O
The remaining zones form escape routes (VII). Remember that a falling tree can also overturn other trees. Therefore, the next
workstation must not be closer than 2,5 x the height of the felled tree (VIII).
Ensure good visibility from the workplace; that is why take special care when cutting trees in difficult terrain conditions, e.g.,
mountains.
It is forbidden to start work during precipitation and in case of high air humidity, e.g., fog.
Wear protective clothing and personal protective equipment.
Before starting cutting, perform a trial wood cut in safe conditions, e.g., cutting wood placed on the saw-horse.
Avoid cutting wires, young trees, and wooden beams.
Do not stand on cut wood.
Starting and stopping the chainsaw
Make sure that the kickback brake is in the rear position.
Remove the guard from the guide bar and chain.
Do not start the chainsaw without the following parts being correctly fitted: guide bar and chain.
Set the switch to the on - I position.
Slowly and fully press the fuel pump 7-10 times. The fuel should be visible inside the pump (IX).
Pull the choke lever out and move it to the CHOKE (X) position.
Rest the chainsaw on a stable surface, ensuring that the chain and bar do not touch anything. Hold the handle with your left hand
while pulling the starter rope vigorously with your right hand. (XI)
Caution! Do not start the chainsaw while holding it in your hands. The chain can touch body parts and cause serious
injury.
This will allow the fuel to be distributed around the saw's fuel system. Then close the choke lever to the START position and pull
the starter cord vigorously once more. When starting the engine, let go of the starter cord. Allow the engine to warm up with the
choke lever slightly extended and then close it fully to the RUN position.
If you hear any suspicious sounds or vibration, switch the chainsaw off immediately.
To switch off the chainsaw when you have finished working, release pressure on the handle lever and let the engine idle for a
while. Then switch it to the off - O position and wait for the chain to stop. Once the chain has stopped, the chainsaw should be
serviced.
Before starting work, it is still important to check the extent to which the chain is oiled. To do this, check at the medium speed
setting that the chain splashes oil slightly. With the chainsaw switched on, tilt the guide bar slightly downwards. And if an oil stain is
visible under the bar after 1 minute, this indicates proper chain lubrication. If it is necessary to adjust the amount of oil dispensed,
it must be adjusted using the knob on the underside of the saw.
Chain lubrication oil and fuel should wear off fairly evenly. Each time you top up the fuel, you should also top up the chain lubri-
cation oil.
Working with the power saw
Once all the steps described in the above sections have been completed, you can start using the saw.
Check the correct operation of the kickback brake before each start of the saw. To do this, hold the chainsaw horizontally, let go
of the front handle and let the guide hit a stump or piece of wood. The height from which the chainsaw must be let go depends on
the length of the chain guide. If the brake does not work, have the chainsaw repaired and adjusted at an authorised repair shop.
