• First cut a force-relief groove from the taut side (1), and then cut it on the side that prevents loosening (2).
Pruning precautions
• If the branches under the tree are pruned first, the trunk will not be supported by the branches. The trees will roll, causing serious or fatal injuries.
1) Turn the main pole over and then trim the branches on it.
2) Do not stand on the log for trimming operations.
Logging precautions
• Inexperienced personnel are prohibited from approaching dangerous logging sites, otherwise serious or fatal personal injury and/or property damage may
be caused.
1) Please do not log alone.
• The branches or other objects from the fallen trees may fall on the bystanders, causing serious injury and/or property damage.
1) Consider the direction of the tree and cut it in such a way as to ensure that it falls cleanly.
2) Bystanders, children and animals are not allowed to stay within 2,5 tree lengths.
3) Observe the canopy of the tree and the canopy of adjacent trees to ensure that there is no interference from branches when the canopy falls.
• When the tree falls, the trunk may break or bounce toward the operator, potentially causing serious or fatal injuries.
1) Plan the escape route around.
2) Observe the direction in which the tree fell and escape to the planned escape route.
3) Don't go uphill.
• Obstacles on the work site or escape route will hinder people trying to escape. People fleeing may fall, leading to serious or fatal injuries.
1) Clean up obstacles in the work area and escape route.
• If there are fixed chains or stabilizing ropes on the trunk, the tree may fall uncontrollably and prematurely, causing serious or fatal injury and/or property
damage to the operator.
1) Do not use hairpin chains.
2) Use a stable rope.
3) If the tree falls prematurely: Please stop logging and evacuate along the escape route.
• When cutting, if the head of the guide plate touches the object or the wood clamps and squeezes the chain, it may cause rebound. Sometimes the head of
the guide plate touches the object and a sudden reaction force will be created, which will pop up the guide plate and eject towards the operator, causing
injury.
• If the direction in which the tree falls is uncontrollable or the tree falls on top of other trees, operators cannot complete logging work in a controlled manner.
1) Stop logging operations and use ropes to select suitable vehicles to pull down trees.
Rebound warning
The following conditions may cause the chain saw to rebound:
• The guide head of the running chain saw touches a hard object or makes an emergency brake.
• The head of the running chain saw's guide plate is touched.
Tension warning
When using the guide plate to cut from top to bottom, the pulling force of the chain saw is facing the opposite direction of the operator.
If the running chain saw touches a hard object and is clamped, the operator will lose control of the chain saw, causing serious or fatal injury.
• Grasp the chain saw handle tightly.
• Operate the chain saw as described in the manual.
• Keep the guide plate straight and cut.
• Please use full speed when cutting.
