2.8 General instructions

The workshop where chain saw repairs are to be done must be equipped with safety equipment as set out in local provisions.

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

In this workshop manual the following boxes indi- cate where caution should be taken.

WARNING!

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

NOTE!

The warning text warns of the risk of ma- terial damage if the instructions are not followed.

2.9 Special instructions

The fuel that is used in a chainsaw poses the fol- lowing hazards:

The fuel and its fumes are toxic.

May cause irritation to skin or eyes.

May cause breathing difficulties.

Highly flammable.

When using compressed air the air jet should never be pointed at the body. Air can be forced into the bloodstream and cause fatal injury.

Wear ear protection when testing saws.

After testing a saw do not touch the silencer until it has cooled down. The silencer gets very hot and you may burn yourself. Wear protective gloves when working on the silencer.

The guide bar, chain and clutch cover (chain brake) must be fitted before the saw is started. If not, the clutch may come loose and cause injury.

Poor chain lubrication can result in failure of the chain, which could cause serious or fatal injury.

Take care to ensure that the spring inside the starter assembly does not fly out and cause injury. Wear eye protection. If the spring is under compression when the pulley is removed it could fly out and cause injury.

Before removing the tensioning spring from the chain brake, ensure that the brake is in the on position, otherwise the spring may fly out and cause injury.

After completing the repair the chain brake must be tested, see “Chain brake – reassembly \ Operating test”.

Always consider the fire risk. A chainsaw can produce sparks that could start a fire.

Inspect the chain catcher and replace it if it is damaged.
