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 RULES

1.Read the instruction manual in order to familiarize yourself with operation of the chain saw.

2.Before using the chain saw for the first time, arrange to have instruction in its operation. If this is not possible, at least practice cutting round timber on a trestle before beginning work.

3.The chain saw must not be used by children or young persons under 18 years of age. Young persons over 16 years of age may be exempted from this restriction if they are undergoing training under the supervision of an expert.

4.Working with the chain saw requires a high level of concentration. Do not work with the saw if you are not feeling fit and well. Carry out all work calmly and carefully.

5.Never work under the influence of alcohol, drugs or medication.

Proper use

1.The chain saw is intended solely for cutting wood. Do not use it for example to cut plastic or porous concrete.

2.Only use the chain saw for operations described in this instruction manual. Do not, for example, use it to trim hedges or for similar purposes.

3.The chain saw must not be used for forestry work, i.e. for felling and limbing standing timber. The chain saw cable does not provide the operator with the mobility and safety required for such work.

4.The chain saw is not intended for commercial use.

5.Do not overload the chain saw.

Personal protective equipment

1.Clothing must be close-fitting, but must not obstruct mobility.

2.Wear the following protective clothing during work:

A tested safety helmet, if a hazard is presented by falling branches or similar;

A face mask or goggles;

Suitable ear protection (ear muffs, custom or mouldable ear plugs). Octave brand analysis upon request.

Firm leather safety gloves;

Long trousers manufactured from strong fabric;

Protective dungarees of cut-resistant fabric;

Safety shoes or boots with non-slip soles, steel toes, and cut-resistant fabric lining;

A breathing mask, when carrying out work which produces dust (e.g. sawing dry wood).

Protection against electric shock

The chain saw must not be used in wet weather or damp environments, as the electric motor is not waterproof.

1.Only plug the saw into sockets in tested electrical circuits. Check that the system voltage matches that on the rating plate. Ensure that a 16 A line fuse is fitted. Saws used in the open air must be connected to a residual current-operated circuit- breaker with an operating current no higher than 30 mA.

Safe working practices

1.Before starting work, check that the chain saw is in proper working order and that its condition complies with the safety regulations. Check in particular that:

The chain brake is working properly;

The run-down brake is working properly;

The bar and the sprocket cover are fitted correctly;

The chain has been sharpened and tensioned in accordance with the regulations;

The mains cable and mains plug are undamaged;

Refer to the "CHECKS " section.

2.Always ensure in particular that the extension cable used is of adequate cross-section (see "SPECIFICATIONS"). When using a cable reel, wind the cable completely off the reel. When
