temperatures and/or by gripping the hand 

grips excessively tightly. If the symptoms 

occur, the length of time the machine is used 

must be reduced and a doctor consulted.

• 

It is recommended that those operating 

chainsaws for trimming and performing height 

work aided by a rope and belt harness:

–

should never work alone;

–

should be assisted by an operator on 

the ground who has received training on 

appropriate emergency procedures;

– should have received training 

on secure climbing and work 

positions for this type of job;

–

are supplied with belt harnesses, ropes, 

flat belts with end loops, clasp clips and 

other recommended additional safety 

equipment or any other system that prevents 

the operator and chainsaw from falling.

• 

Perform cleaning and maintenance 

before storing the machine after use.

• 

Improper maintenance, use of non-compliant 

spare parts or modification of the safety 

devices can cause damage to the device 

and cause serious injury to the user.

 2.3  CAUSES OF KICKBACK AND 

OPERATOR PROTECTION

Kickback can occur when the nose or tip of the 

guide bar touches an object, or when the wood 

closes in and pinches the chain in the cut.

Contact of the tip can, in certain cases, cause a 

sudden fast reverse action, pushing the guide bar 

upwards and backwards towards the operator.

Pinching of the chain along the top 

of the guide bar can rapidly push the 

chain back towards the operator.

Both the above reactions may cause loss of 

control of the saw, which could result in serious 

injury for operators. Do not rely exclusively 

on the chainsaw built-in safety devices

Chainsaw users should take additional 

precautions to eliminate accident or injury risks 

during cutting operations. Kickback is the result 

of poor use of the tool and/or incorrect operating 

procedures or conditions and can be avoided by 

taking the specific precautions provided below:

• 

Hold the saw firmly with both hands, 

with the thumbs and fingers around the 

chainsaw grips, and position your body 

and arms so that you can resist the force 

of a kickback.

 Kickback can be controlled by 

the operator if all appropriate precautions have 

been taken. Do not allow the chainsaw to start.

• 

Do not fully extend the arms and do 

not saw above shoulder height.

 This 

helps avoid undesired contact with the 

ends and allows for more control over the 

chainsaw in unexpected situations.

• 

Only use the guide bar and chains 

recommended by the manufacturer.

Unsuitable guides and chains can cause 

the chain to break and/or kickbacks.

• 

Follow the manufacturer's instructions 

regarding sharpening and maintenance 

of the chainsaw.

 A decrease in the level of 

depth can cause an increase in kickbacks.

• 

Techniques for using the electric 

chainsaw (battery-operated)

Always observe the safety regulations 

and use the most suitable cutting 

techniques according to the work to be 

performed, following the instructions and 

examples in the user instructions.

• 

Safe carrying of the electric 

chainsaw (battery-operated)

Whenever the machine is to be 

handled or transported you must:

–

turn off the motor, wait for the chain to stop 

and unplug the machine from the mains;

–

apply the protection bar cover;

–

only hold the machine using the handles 

and position the bar in the opposite 

direction to that used during operation;

When using a vehicle to transport the machine, 

position it so that it can cause no danger 

to persons and fasten it firmly in place.

• 

Recommendations for first-time users

Before felling or delimbing for 

the first time, make sure:

–

to have been specifically trained 

to use this type of equipment;

–

to 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.

• 

Handling and correct use of 

battery-operated power tools

a) Make sure that the machine is switched 

off before inserting the battery.

 Inserting 

a battery in an electric device which is 

switched on can cause accidents.

b) Charge battery packs only with 

the chargers recommended by the 

manufacturer. Battery chargers are 

generally specific for each battery type; 

use with other types can cause fire risks.
