2.8 General Instructions

The workshop where the chain saw is to be re- paired must be equipped with safety equipment in accordance with local regulations.

No one may repair the chain saw unless they have read and understood the content of this Workshop Manual.

This workshop manual contains the following warn- ing boxes in relevant places.

WARNING!

The warning box warns of the risk of personal injury if the instruc- tions are not followed.

NOTE!

This box warns of material damage if the instructions are not followed.

2.9 Special Instructions

The fuel used in the chain saw has the following hazardous properties:

The fluid and its vapour are poisonous.

Can cause eye and skin irritation.

Can cause breathing problems.

Is highly inflammable.

When using compressed air, do not direct the jet towards your body. Air can penetrate into the blood stream, which can endanger life.

Wear protective earplugs or earmuffs when test running.

After test running, do not touch the muffler until it has cooled down. Risk of burns. Use protective gloves when working with the muffler.

Do not start the chain saw unless the bar, chain and clutch cover (chain brake) are fitted, otherwise the clutch may loosen and cause personal injury.

Insufficient chain lubrication can result in chain breakage, which can cause serious or even life- threatening injury.

Exercise care to ensure the starter spring does not fly out and cause personal injury. Wear protective glasses. If the spring tension is activated on the starter pulley when it is to be taken up, the spring can fly out and cause personal injury.

Check that the brake is applied when removing the pressure spring on the chain brake. Otherwise the pressure spring can fly out and cause personal injury.

After repairing, check the chain brake, see “Assem- bling chain brake \ Function check”.

Keep in mind the fire risk. The chain saw may emit sparks, which cause ignition.

Check the chain catcher and replace it if it is dam- aged.
