6.1.3 Filling with chain lubrication oil
Fill with chain lubrication oil before using
the machine. For oil filling methods and
precautions (see paragraph 7.3).
6.1.4 Checking the chain tension
This operation must be done
with the machine off and the battery
removed from its housing (par. 7.2.2).
Check the chain tension.
The tension is correct when the drive links
do not slip out of the chain guides if you hold
the chain in the middle of the bar (Fig. 7).
To adjust the chain tension:
1. Loosen the guard knob (Fig. 3.A).
2. Turn the chain tension adjuster screw (Fig.
5.D) to achieve the desired tension;
3. Raise the bar and tighten the
knob securely. (Fig. 8.A).
Never work with the chain loose,
as it can be hazardous if the chain
slips out of the bar guides.
IMPORTANT During the first period of use
(or after replacing the chain) it must be checked
more frequently due to settling of the chain.
