Prepare to Work
Check the Machine
mWARNING! Before performing any checks,
adjustments, repairs or maintenance on the machine, make
sure the battery is not inserted in the compartment.
mCAUTION! The chain will continue to run for several
seconds after turning o the tool.
Before starting work please:
• Check that all the screws on the machine and the guide
bar are tightly fastened;
• Check that the chain is tensioned correctly, sharp and
there are no signs of any damage;
• Check that hand grips and protection devices are clean
and dry, correctly mounted and securely fastened to the
machine;
• Check that the On/O switch and the safety lock button
move freely without forcing and return automatically and
rapidly back to their neutral positions;
• Check that the On/O switch remains locked until the
safety lock button is pressed;
• Make sure the cooling air vents are not clogged with
sawdust or debris;
• Check that the chain’s oil level is not below the "MIN" level
mark; if necessary, top up the oil to 1 cm from the rim of
the ller.
NOTE: You must ll the chain oil tank with bar and chain
oil before using your chain saw.
Adjusting the Chain Tension
1. Tension the chain by turning the chain tensioning ring
clockwise (Fig. 12). A cold chain will be correctly tensioned
when there is no slack on the underside of the guide bar;
the chain is snug, but it can be turned by hand without
binding.
2. The tension is correct when the drive links on the chain do
not slip out of the chain guide on the bar when the chain is
pulled up from the middle of the bar (Fig. 13).
NOTE: If the chain is too tight, it will not rotate. Loosen the
end cover knob slightly and turn the chain tension knob
1/4 turn counterclockwise. Lift the tip of the guide bar up
and retighten the cover cap knob. Ensure that the chain
can be rotated by hand without binding.
NOTE: A new chain tends to stretch; check the chain
tension frequently, and adjust tension as required.
Chain Lubrication
IMPORTANT! Only use a good quality bar and chain oil
designed specically for use with chain saws to ensure optimal
lubrication of the cutting parts. Do not use oil containing
impurities to avoid clogging the tank lter and permanently
damaging the oiler.
IMPORTANT! The chain lubricating oil is bio-degradable. The
use of mineral oil or engine oil can have a serious impact on
the environment. It is essential that you use good quality oil to
lubricate the cutting parts eectively. Used or poor quality oil
