Below is Autojare Gasoline Chainsaw YJ5201 Construction


Gasoline Chainsaw is used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks in wild-land fire suppression and harvesting of firewood. Chainsaws with specially designed bar and chain combinations have been developed as tools for use in chainsaw art and chainsaw mills. Specialized chainsaws are used for cutting concrete. Chainsaws are sometimes used for cutting ice, for example for ice sculpture and in Finland for winter swimming.


Autojare Gasoline Chainsaw YJ5201 use a number of safety features to protect the operator.

Chain brake

The chain brake is located in the clutch cover. Here a band tensions around the Clutch drum stopping the chain within milliseconds. The chain brake is released by the upper handle with the hand or wrist. The brake is intended to be used in kick-back moments.

Chain catcher

The chain catcher is located between the saw body and the clutch cover. In most cases it looks like a hook made in aluminum. It is used to stop the chain when it derails from the bar and shortens the length of the chain. When derailing the chain swings from underneath the saw towards the operator. The shorting prevents hitting the operator, but it hits the rear handle guard.

Rear handle guard

The rear handle guard protects the hand of the operator when the chain derails.

Chain

Some chains show safety features as safety links as on micro chisel saws. These links keep the saw close to the gap between two cutting links and lift the chain when the space at the safety link is full with saw chips. This lifts the chain and lets it cut slower.

These features do not guarantee that the operator will not be harmed. The best protection is experience.
