Causes and operator prevention of kickback:

Kickback may occur when the nose or tip of the

guide bar touches an object (Fig B3), or when

the wood closes in and pinches the saw chain in

the cut.

Tip contact in some cases may cause a sudden

reverse reaction, kicking the guide bar up and

back towards the operator.

Pinching the saw chain along the top of the guide

bar may push the guide bar rapidly back towards

the operator.

Either of these reactions may cause you to lose

control of the saw which could result in serious

personal injury. Do not rely exclusively upon the

safety devices built into your saw. As a chain

saw user, you should take several steps to keep

your cutting jobs free from accident or injury.

Kickback is a result of tool misuse and/or

incorrect operating procedures or conditions and

can be avoided by taking proper precautions as

given below:

• Maintain a firm grip, with thumbs and fingers

encircling the chain saw handles, with both

hands on the saw and position your body and

arm to allow you to resist kickback forces.

Kickback forces can be controlled by the

operator, if proper precautions are taken. Do not

let go of the chain saw.

• Do not overreach and do not cut above

shoulder height.

This helps prevent unintended

tip contact and enables better control of the chain

saw in unexpected situations.

• Only use replacement bars and chains

specified by the manufacturer.

Incorrect

replacement bars and chains may cause chain

breakage and/or kickback.

• Follow the manufacturer’s sharpening and

maintenance instructions for the saw chain.

Decreasing the depth gauge height can lead to

increased kickback.

Additional Safety Recommendations

1.Manual use. All persons using this machine

must read the user manual completely with

extreme care. The user manual must be included

with the machine in the case of sale or loan to

another person.

2.Precautions prior to machine use. Never

permit this machine to be used by any persons

who are not perfectly familiar with the manual

instructions. Inexperienced persons must follow a

training period operating on a saw horse only.

3.Control checks. Check the machine with care

before use each time, especially if it has been

subject to strong impact, or if it shows any signs

of malfunction. Perform all operations described

in the chapter “Maintenance & Storage – Before

each use”.

4.Repairs and Maintenance. All the machine

parts that can be replaced personally, are clearly

explained in the “Assembly / disassembly”

instructions chapter. Where necessary, all other

machine parts must be replaced exclusively by an

Authorised Service Centre.

5.Clothing. (fig B1) When using this machine the

user must wear the following approved individual

protective clothing : close-fitting protective

clothing, safety boots with non-slip soles, crush-

proof toe protectors and cut-proof protection, cut-

proof vibration-proof gloves, protective goggles or

safety visor, ear protection muffs and helmet (if

there is any danger of falling objects). Obtainable

from a workwear supplier

6.Health precautions – Vibrations and Noise

levels. Please be aware of noise restrictions in

the immediate area. Prolonged machine use

exposes the user to vibrations that can generate

“white finger phenomenon” (Raynaudʼs

Phenomenon), carpal tunnel syndrome and

similar disturbances.

7.Health precautions – Chemical agents. Use oil

which is approved by the manufacturer.

8.Health precautions - Heat. During use, sprocket and

chain reach very high temperatures, take care not to

touch these parts while hot.

Transport and storage precautions. (fig B2) Each

time the work area is changed to another location,

disconnect the machine from the mains supply and

activate the chain brake lever. Mount the guide bar

cover guard each time before transporting or

storage. Always carry the machine by hand with the

bar facing backwards, or when transporting the

machine in a vehicle, always attach it securely to

prevent damage.

Kickback reaction. (fig B3) The kickback reaction

consists of a violent upwards-reverse action of the

bar towards the user. This generally occurs if the

upper part of the bar nose (called the “kickback

danger zone” ) (see red marking on the Guide Bar)

comes into contact with some object, or if the chain

is blocked in the wood. Kickback can make the user

loose control of the machine provoking dangerous

and even fatal accidents. The chain brake lever and

other safety devices are not sufficient to protect the

user against injury: the user must be well aware of

the conditions that can provoke the reaction, and

prevent them by paying very close attention

according to experience, together with prudent and

correct machine handling (for example: never cut

several branches at a time because this can cause

accidental impact on the “kickback danger zone”

Work area safety
