Move the guide bar (20) 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 (20), adjust when necessary.
Place the casing (10) in its place and fix by slightly tightening guide bar fixing nuts
(7).
Strain the chain appropriately using the chain tension adjustment screw (8). 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 (7) 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 (18).
Pour in maximally 260 ml of oil (be careful to avoid contamination of oil during filling
of the tank).
Screw oil filler plug (18).
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
Working conditions Petrol: oil 25 : 1
1 L gasoline - 40ml two strocke oil
Unscrew fuel filler plug (15). Pour in previously prepared fuel blend (max. 550 ml).
Screw fuel filler plug (15).
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 (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).
