Chain brake
The chain brake is a device which stops the chain instantaneously if the chain
saw recoils due to kickback.
Normally, the brake is activated automatically by inertial force. It can also be
activated manually by pushing the brake lever (left-hand guard) down toward
the front.
When the brake operates, a white cone pops up from the base of the brake lever.
Releasing the Brake
Pull the brake lever up toward the left-hand handle until it clicks into place.
When the brake operates and the chain is stopped, release the throttle lever.
Safe chainsaw operation
Felling a tree (Figs. 14-16)
If two or more persons are working at the same time on felling and cutting back
then the minimum distance between the tree being felled and the tree being cut
back should be at least twice the height of the tree being felled (Fig. 14). When
felling trees, care must be taken to ensure that no other persons are endangered,
no power supply lines are hit and no material damage is caused to equipment or
property. In the event that a tree comes into contact with a power supply line, he
responsible power supply company should be informed immediately.
When working with the saw on a slope, the operator of the chainsaw must be
standing at a higher point on the slope than the tree being felled, as the tree will
roll or slip downhill once it has been felled (Fig. 15). Before felling the tree you
must first plan and if necessary clear an escape route. This escape route must
lead away diagonally in the opposite direction to the expected fall direction –
this can be seen in Fig.16(A= danger zone, B= direction of fall, C= escape zone).
Before felling the tree you must take into account the natural inclination of the
