The operator is obliged to stop work immediately if someone is within the risk zone. Chain shot When a saw chain breaks, parts of the saw chain can be thrown out at high speeds. If saw chain breaks with a whiplash, the speed of these parts may be several times higher than the speed of the saw chain. Danger! Chain shots are associated with danger to life! The energy in the event of chain shot can be equivalent to that of a bullet from a rifle. It is therefore essential to follow the instructions regarding the use of the head and maintenance of the saw unit.

In the event of chain shots, parts of the saw chain can travel outside of the head’s risk zone. When activating the saw unit, the head must be positioned so that there is no risk of chain shots hitting: • people outside the risk zone. • other machines. • other property. The head is equipped with a chain shot guard. The guard is integrated into the head’s frame. Under no circumstances may the guard be modified. Do not use the head if the guard has been damaged or its function has otherwise been impaired. A crushing risk exists by the head’s moving parts. Follow the instructions in this...
