Preparing To Work
Checking the Machine
m
WARNING!
Before performing any checks,
adjustments, repairs or maintenance on the machine, make
sure the batteries are not inserted in the compartments.
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 chain brake is working efficiently;
• Check that the trigger switch and the safety button move
freely without forcing and return automatically and rapidly
back to their neutral positions;
• Check that the trigger switch remains locked until the
safety 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 "OIL min"
level mark; if necessary, top up the oil to 1 cm from the
rim of the filler.
NOTE: You must fill 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 end cover + chain
tensioning knob clockwise (Fig. 5). 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.

NOTE: Pay attention when loosening the chain by turning
the end cover + chain tensioning knob counterclockwise. If
loosened excessively, the knob and end cover may come off.
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. 6).

3. Pull the front hand brake towards the front handle in the
OFF position (Fig. 7). Using a screwdriver, run the chain
along the guide to check that it moves smoothly.

Chain Lubricant
IMPORTANT! Only use a good quality bar and chain oil
designed specifically for use with chain saws to ensure optimal
lubrication of the cutting parts. Do not use oil containing
impurities to avoid clogging the tank filter 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 effectively. Used or poor quality oil
does not guarantee good lubrication and reduces the lifespan
of the chain and bar.
