6.1 PRELIMINARY PROCEDURES
Before starting to work, it is necessary to carry
out several checks and operations to ensure you
can work efficiently and in maximum safety.
IMPORTANT The machine is supplied with
the fuel and chain lubrication oil tanks empty.
6.1.1 Refuelling
Fill with fuel before using the machine. For
preparing the mixture, refuelling methods
and precautions (see paragraph 7.3).
6.1.2 Filling with chain lubrication oil
Fill with chain lubrication oil before using
the machine. For oil filling methods and
precautions (see paragraph 7.4).
6.1.3 Checking the chain tension
Perform all operations
with the engine off.
Always wear heavy duty work gloves.
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. 11).
To adjust the chain tension:
1. loosen the guard nut, using
the supplied wrench;
2. turn the chain tension adjuster screw (Fig.
9.A) to achieve the desired chain tension;
3. raise the bar and tighten the guard nuts
securely using the wrench supplied (Fig. 10).
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 it must be checked more frequently
due to settling of the chain.
6.2 SAFETY CHECKS
Run the following safety checks and
check that the results correspond to
those outlined on the tables.
Always carry out the
safety checks before use.
Always carry out a daily inspection
of the machine before use, after a
fall or other impact to detect any
