Overchoking

Should the engine become flooded due to overchoking, turn the ignition switch off, unscrew the spark plug, wipe

it dry or replace, pull the recoil starter several times without the spark plug in place and with choke in the open

position (c). This will help clean and ventilate the combustion chamber.

■ CHAIN BRAKE

• The chain saw is equipped with an automatic chain brake to stop the saw chain rotating when activated, e.g .

kickback during saw cutting. The brake is automatically operated by inertial force, which acts on the weight

fitted inside the chain brake handle. The brake can also be operated manually when the brake handle is

pushed forward towards the guide bar.

• To release the chain brake, pull back the brake handle toward the front handle until a “click” sound is heard.

• The chain brake is now reset and the saw chain is able to rotate.

■ How to check:

• You must check the chain brake operation before each usage by running the chain saw at full throttle and

pushing the chain brake handle forward (b).

• The saw chain should stop immediately with the engine at full speed.

• If the saw chain is slow to stop or does not stop, replace the chain brake band or chain brake assembly before

use.

• Disengage the chain brake after testing. (a)

■ KICKBACK SAFETY PRECAUTIONS FOR CHAIN SAW USERS

• Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood being cut

closes in and pinches the saw chain. Top contact of the guide bar may cause a fast 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 the operator to lose

control of the chain saw which could result in serious personal injury.

• Do not rely exclusively on the safety devices built into the chain saw. As a chain saw user you should take

several steps to keep the cutting work free from accident or injury.

• With a basic understanding of kickback you can reduce or eliminate the element of surprise. Sudden surprise

contributes to accidents.

• Keep a good grip on the chain saw with both hands, the right hand on the rear handle, and the left hand on the

front handle, when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw

handles. A firm grip will help you reduce kickback and maintain control of the chain saw.

• Make certain that the area in which you are cutting is free from obstructions. Do not let the nose of the guide

bar contact a log, branch, or any other obstruction which could be hit while you are operating the chain saw.

• Cut at high engine speeds.

• Do not overreach or cut above shoulder height.

• Follow manufacturers sharpening and maintenance instructions for sharpening saw chain.

• Only use replacement guide bars and saw chains specified by the manufacturer or the equivalent.

■ BEFORE STARTING WORK

Always follow the safety regulations:

• Before starting work we recommended to first practice sawing easy logs. This also helps you get accustomed

to your chain saw’s operation.

• The chain saw must only be used for cutting wood. It must not be used to cut other types of material.

• The chain saw should cut easily without force. When cutting apply only light pressure while running the engine

at full throttle.

• When the saw chain is caught in the cut, do not attempt to pull it out by force, turn off the engine and use a

wedge or a lever to release the saw chain and guide bar.
