7. Pull the starter grip again until
the engine starts as normal.
8. When the engine is started, simultaneously
activate the throttle trigger lever (Fig.
12.B) and the interlock lever briefly (Fig.
12.C) to cancel fast tick over. Allow the
engine to run idle for 10-15 seconds.
9. Disengage the chain brake (par. 5.7).
IMPORTANT Do not let the engine
run at high speed with the chain brake
engaged, as this could cause overheating
and damage to the clutch.
10. Let the engine run idle for at least 1
minute before using the machine.
IMPORTANT If the starter hand grip is pulled
repeatedly with the choke engaged, it may
flood the engine and make starting difficult.
If the engine floods (see paragraph 15.5).

6.3.2 Warm start

When hot starting (immediately
after stopping the engine):
1. Make sure the chain brake
is engaged (par. 5.7).
2. Press the primer device control button (Fig.
13.F) 6 times to help start the carburettor.
3. Engage the choke (position «B» - par.
5.2) and then immediately disengage
again (position «A» - par. 5.2); this
will engage the fast tick over.
4. Follow points 4 - 7 - 8 - 9 in the
previous procedure (par. 6.3.1)

WORKING

Before felling or delimbing for
the first time, make sure:
– you have been specifically trained
to use this type of equipment;
– you have carefully read the safety
regulations and user instructions
contained in this manual;
– you practise first on logs on the ground
or attached to trestles, in order to
get familiar with the machine and the
most suitable cutting techniques.
To operate with the machine
proceed as described below:
• Always disengage the chain brake,
before using the throttle.
• The machine must always be firmly held in
both hands, with the left hand on the front
hand grip and the right hand on the rear hand
grip, even if the operator is left handed.
6.4.1 Checks to be conducted
whilst working
6.4.1.a Checking the chain tension
The chain tends to stretch gradually
as you work, so you need to check its
tension frequently (par. 6.1.3).
6.4.1.b Checking the oil delivery
IMPORTANT Never use the machine
without lubrication! The oil tank may also
be empty every time the fuel runs out.
Make sure you top up the oil tank every
time you refuel the machine (par. 7.4).
Make sure the bar and the chain are
in place when you check the oil delivery.
Start the engine (par. 6.3), keep it running
at medium power and check if the chain
oil is delivered as shown in (Fig.15).

6.5 WORK TECHNIQUES

6.5.1 Delimbing a tree

Make sure there is nothing or anybody
in the area where the branches will fall.
For pruning high up using a rope
and a belt harness, carefully follow
the instructions under par. 6.7.
1. Stand opposite the branch you want to cut.
2. Start cutting lower branches
followed by the higher ones.
3. Cut downwards to prevent the bar
from getting jammed (Fig. 16).

6.5.2 Felling a tree

IMPORTANT Where two or more persons
are working together on felling and bucking
operations, such operations must be performed
in separate areas at a distance from each
other of at least 2.5 times the height of the tree
being felled. Do not fell trees if this involves
risks of injuring people, coming into contact
with a power line or causing any form of
damage. If the tree should come into contact
