it is recommended to raise and support the
trunk using branches, logs or blocks of wood.
It is easier to saw a log using the
spiked bumper (Fig. 1.I):
1. Plant the spiked bumper into the log and use
it as a pivot. Cut with an arched motion to
make the bar penetrate the wood (Fig. 18);
2. Repeat several times if necessary, changing
the point where you plant the spiked bumper.
• Trunk lying on the ground
When the entire trunk is lying on the
ground, it is bucked from the top
down (overbucking) (Fig. 19.A).
– Cut up to half the diameter, roll the log over
and finishing sawing on the other side.
• Trunk resting on one end only
When the trunk is resting on one end only:
– saw through 1/3 of the diameter from the
bottom up (underbucking) (Fig. 20.A);
– then perform the final cut, overbucking
to reach the first cut (Fig. 20.B).
• Trunk resting on both ends
When the trunk is resting on both ends:
– saw through 1/3 of the diameter from the
top down (overbucking) (Fig. 21.A);
– then perform the final cut, underbucking the
lower 2/3 to reach the first cut (Fig. 21.B).
• Sloping trunk
Always stand uphill when bucking
a sloping trunk (Fig. 22).
During the operation, to maintain control when
the cut is almost complete, reduce the bucking
pressure without removing removing your
hands from the machine handgrips. Take all
necessary precautions to prevent the machine
from coming into contact with the ground.
6.5 STOP
To stop the machine:
• Release the throttle control lever (Fig. 10.A).
• Press the safety button and turn off the
electrical circuit (light off) (Fig. 9.A).
After releasing the throttle
control it takes a few seconds for
the toothed chain to stop.
Always stop the machine:
– when moving between work areas.
Do not keep your finger on the safety
button when moving the machine to avoid
accidentally enabling the machine.
6.6 AFTER OPERATION
1. Remove the battery from its housing
and recharge it (par. 7.2.2).
2. Mount the bar cover.
3. Allow the motor to cool before
storing in an enclosed space.
4. Loosen the bar fastening nuts
to reduce chain tension.
5. Carefully remove any dust and debris
and remove all traces of sawdust or oil
deposits from the chain. (par. 7.4).
6. Check there are no loose or damaged
components. If necessary, replace
the damaged components and tighten
any screws and loose bolts.
IMPORTANT Always remove the battery
(par. 7.2.2) and fit the blade guard whenever
the machine is unused or left unattended.

Before conducting any inspections,
cleaning or maintenance/adjustment
interventions on the machine:
• Stop the machine;
• Wait until the chain is stationary;
• Remove the battery from its housing;
• Apply the bar cover, except when working
directly on the chain or bar itself.
• Wait until the motor is sufficiently cold;
• Read the relevant instructions;
• Use suitable clothing, protective
gloves and goggles;
• The frequency and types of maintenance
are summarised in the "Maintenance
