User Manual

Move the guide bar (9) away from the driving chain wheel, so chain guiding links are placed in the guide bar groove.
Ensure the pin of the chain tension adjustment screw is in the middle of the lower hole of the guide bar (9), adjust when necessary.
Place the casing in its place and fix by slightly tightening guide bar fixing nut (12).
Strain the chain appropriately using the chain tension adjustment screw (11). Chain tension is appropriate when the chain can be lifted
by 3 to 4 mm in the middle of the guide bar in horizontal position.
Firmly tighten guide bar fixing screw (12) while holding the guide bar tip.
Prior to guide bar and chain installation ensure that position of chain cutting blades is appropriate (correct position of the chain on the
guide bar is shown on the tip of the guide bar). Always wear protective gloves during checks and installation of the chain to prevent cuts
from sharp edges of the chain.
New chain requires start-up period, which lasts approximately 5 minutes. Chain lubrication is very important in this phase. Check chain
tension after start-up period and readjust if necessary.
Check and adjust the chain tension frequently. Too loose chain can easily slide off the guide bar, quickly wear out or quickly wear out the
guide bar.
3.3. Filling saw tank with oil.
Oil tank in new chain saw is empty. Fill the tank with oil prior to first use.
Unscrew oil filler plug (5).
Pour in oil (be careful to avoid contamination of oil during filling of the tank).
Screw oil filler plug (5).
Do not use oil that has been already used or regenerated, as this may damage the oil pump. Use SAE 10W/30 oil for the whole year or
SAE 30W/40 in summer and SAE 20W/30 in winter.
4. Operation and settings
4.1. Switching on. Switching off.
The mains voltage must match the voltage on the rating plate of the saw. Hold the chain saw with both hands when starting up
and during operation. Switching on - press the switch lock button (4) and then switch button (1). In case the chain saw does not start,
release the brake lever (7).
4.2. Switching off - release pressure on the switch (1). Release pressure on the switch button (1) to stop the chain saw. Strong sparking
on the commutator may appear. This is normal and safe for chain saw operation.
When switched on, the chain saw starts to work with full speed.
4.3. Checking chain lubrication.
Check lubrication of the chain and oil level in the tank before starting to work. Switch on the saw and hold it above ground. If you see enlarging oil
marks, the chain lubrication works well. If there are no oil marks or they are very small, use oil feed adjustment screw (13) to make appropriate
adjustments. In case the adjustment brings no effects, clean oil outlet, upper hole of chain tension and oil way or contact service.
Make adjustments when the saw is switched off, observe precaution measures and do not allow the guide bar to touch ground. Operate
the tool safely and maintain at least 20 cm distance from ground.
Use oil feed adjustment screw (13) to set amount of supplied oil accordingly to respective operating conditions.
MIN position - oil flow decreases.
MAX position - oil flow increases.
When cutting hard and dry wood and using whole length of the guide bar when making a cut, set the oil feed adjustment screw (13) to
the MAX position.
You can reduce amount of oil supplied by turning oil feed adjustment screw (13) to MIN position, when cutting soft and damp wood, or
when only part of the working length of the guide bar is used.
Depending on ambient temperature and amount of oil supplied, you can operate the chain saw for 15 to 40 minutes per one filling the oil
tank.
4.4. Chain lubricants.
Durability of chain and guide bar depends heavily on quality of lubricant. Use only lubricants, which are designed for chain saws.
Never use regenerated or previously used oil for chain lubrication.
4.5. Chain guide bar.
Guide bar (9) is exposed to heavy wear especially in tip and bottom part. To prevent side wear due to friction, it is recommended to turn over the
guide bar every time the chain is sharpened. Clean the guide bar groove and oil holes on that occasion. Guide bar groove is rectangular. Check the
groove against wear. Put rule to guiding strip and outer surface of a chain tooth. If you observe distance between, the groove is correct. Otherwise
the guide bar is worn out and needs to be replaced.
4.6. Chain wheel.
Driving chain wheel is subject to especially heavy wear. Replace the chain wheel when you observe clear signs of wear of wheel teeth.
Worn chain wheel additionally reduces durability of chain. Chain wheel should be replaced by authorized service workshop.
4.7. Chain brake.
The saw features automatic brake, which stops the chain in case of recoil during chain saw operation. The brake engages automatically
when force of inertia is applied to a weight located inside the brake casing. The chain brake can also be switched on manually, when the
brake lever (7) is moved towards the guide bar (9). Switching the chain brake stops the chain movement in 0.12 sec.
4.8. Braking check.
Ensure the brake operates correctly before each use of the saw.
Put operating saw on the ground and open the throttle fully for 1 - 2 seconds to allow the saw engine to operate at its maximum speed.
Push the brake lever (7) forward. The chain should stop immediately.
In case the chain stops slowly or does not stop at all, replace the brake band and clutch drum before using the chain saw again.
To release the brake, pull the brake lever (7) towards the main handle (3) so you can hear sound typical of blockade snapping.
Ensure the chain brake operates correctly and the chain is sharp. It is very important for keeping potential recoil at a safe level.
In case the brake does not operate efficiently, adjust it or repair in authorized service site.
In case the engine operates at high speed with the chain brake switched on, the saw clutch will overheat. When the chain brake engages
during operation of the engine, release the switch off immediately and stop the chain saw.
4.9. Chain tension adjustment.
Cutting chain tends to lengthen during operation due to higher temperature. Longer chain loosens and may slip off the guide bar.
Loosen the guide bar fixing nut (12).
Ensure the chain (8) remains in the guiding groove of the guide bar (9).
Use a screwdriver to turn the chain tension adjustment screw (8) clockwise, until the chain is strained appropriately (it should slightly hold
the guide bar in horizontal position).
Check the chain tension again (it should be possible to lift the chain by approximately 3 - 4 mm in the middle of the guide bar).
Tighten firmly the guide bar fixing nuts (12).
