• 

When the operator is working close to 

vertical trunks, with reduced lateral force 

on the working position, stable support is 

sufficient to maintain a safe working position. 

• 

When the operator moves away from the 

trunk, the lateral forces increase and it 

is necessary to eliminate or offset them 

using one of the following methods:

– add an additional fastening point 

for the main rope to stabilise it;

–

use a flat strap with end slots adjustable 

from the harness fastened to an 

additional fastening point (Fig. 30);

• 

Use of a temporary foot stirrup, created by 

a ring belt, can make it easier to achieve 

a stable working position. Fig. 31).

 6.7.2 

Using the chainsaw with one hand 

Do not work with one hand if you 

are in an unstable working position or 

when using a chainsaw instead of a 

handsaw to cut small sized branches. 

The chainsaw must be used 

with one hand only when:

• 

the operator is not able to reach a working 

position that allows him to use both hands,

•  the operator needs to use one hand to 

support himself in the working position,

•  the cutting involves extension of the operator's 

upper limb beyond his own body line (Fig. 32). 

The operator must never: 

• 

perform cutting operations with the 

kickback area corresponding with 

the point of the chainsaw bar;

•  “hold and cut” sections;

• 

attempt to catch falling sections.

 6.8  ADVICE FOR OPERATION

 IMPORTANT 

  Stop the machine (par. 

6.9) when moving between work areas.

Stop the machine immediately 

if the chain stops during sawing. 

If the chainsaw should get stuck during 

pruning high up (using a rope and a 

belt harness), the operator must:

1. 

stop the machine immediately;

2. 

fasten it securely to the part of the branch 

between the trunk and the cut section 

or to a rope not attached to the tool;

3. 

pull the chainsaw out from the cut, 

lifting the branch where necessary;

4. 

if necessary, use a handsaw or second 

chainsaw to free the trapped chainsaw, 

cutting at a minimum distance of 30 cm from 

the trapped chainsaw. Cutting operations to 

free the chainsaw must always be performed 

towards the end of the branch, (i.e. between 

the trapped chainsaw and the end of the 

branch and not between the trunk and the 

trapped chainsaw). This will prevent the 

chainsaw from being dragged by the part 

of the branch that is cut away, which would 

complicate the situation even further. 

 6.9  STOP

To stop the machine:

1. 

Release the throttle trigger lever  (Fig. 13.A).

2. 

Press the safety button and turn off the 

electrical circuit (light off) (Fig. 12.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.

 6.10 AFTER USE

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 nut 

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.
