separately. Brake lever (6) must be in the upper (vertical) position. Unscrew the guide bar fixing nuts and remove the casing. Put
the chain (15) onto driving chain wheel located behind the clutch. Install the guide bar (14) (slide it behind the clutch) onto guiding
screws and push towards driving chain wheel. Put the chain (15) onto guide bar chain wheel (16) from below.
Move the guide bar (14) 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 (14), adjust when necessary.
Place the casing in its place and fix by slightly tightening guide bar fixing nuts. Strain the chain appropriately using the chain
tension adjustment screw. 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 screws 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 (13). Pour in maximally 260
ml of oil (be careful to avoid contamination of oil during filling of the tank). Screw oil filler plug (13). 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.
3.4. Filling the fuel tank.
When filling the fuel, follow these rules:
Engine must not work. You must not spill the fuel. Accordingly to the below table, mix petrol (lead-free with octane number
95) with good quality engine oil for two stroke engines. Recommended fuel blend ratio. Working conditions Petrol: oil 25 : 1
1 L gasoline - 40 ml two stroke oil Unscrew the tank cap cover for fuel (12). Pour in previously prepared fuel blend (max. 550 ml).
Screw the tank cap cover for fuel (12). Most problems with combustion engines result directly or indirectly from fuel used. You
must not use oil designed for 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 (11) to
switched on position. Place the saw on stable ground. While holding the saw pressed against ground, pull slowly the starter line
(10). Sistem EasyOn conducive to recoil start function, for easy starting. After starting the saw, press the throttle lever lock (1)
and throttle level (8) slightly (choke cable will move automatically to switched off position).
Allow the engine to heat up with throttle lever (8) 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 (8) and allow the engine to run idle for a few minutes. Set the ignition switch (11) 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 (7) 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 (7) to set amount of supplied oil accordingly to respective operating conditions.
