four-stroke engines to prepare fuel blend.
4. Operation and settings
4.1. Starting the engine.
Hold the chain saw with both hands during operation.
Check level in the fuel tank and the oil tank.
Ensure the brake lever (6) is in the switched on position (moved to the front).
When engine is cold, pull out choke (2).
Set the ignition switch (14) to switched on position.
Place the saw on stable ground.
While holding the saw pressed against ground, pull slowly the starter line (13). Sistem EasyOn conducive to recoil start
function, for easy starting.
After starting the saw, press the throttle lever lock (1) and throttle level (11) slightly (choke cable will move automatically
to switched off position).
Allow the engine to heat up with throttle lever (11) slightly pressed.
Move the brake lever (6) to switched off position (to the back).
In case the engine does not start at the first try, pull out the choke (2) halfway and pull the starter line again.
Do not start the engine while holding the saw in hands. During start up the chain saw must rest on ground and be held
firmly. Ensure the chain is free to move without touching any object. Do not cut any material with choke cable pulled out.
4.2. Stopping the engine.
Release the throttle lever (11) and allow the engine to run idle for a few minutes.
Set the ignition switch (14) to STOP position.
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 (9) 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 (9) 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 (9) to the MAX position.
You can reduce amount of oil supplied by turning oil feed adjustment screw (9) 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 (tank capacity is 260 ml).
Oil tank should be almost empty when the fuel tank is emptied. When filling the fuel remember about filling oil tank as
well.
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 (20) 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.
