Operating
Before using the high pruner, we strongly recommend that you read and understand the concept of a
rebound in chain saws.
Definition of the rebound
When the top edge or tip of the saw rail comes into contact with wood or other hard objects, the
device is flung towards the user at high force which can cause extremely severe injuries.
Which area is most likely to cause rebound.
As shown in Fig 11
How to reduce rebound occurence
The risk of a rebound can be reliably reduced only by working
cautiously and correctly!
Suggestions for general sawing methods
Pull sawing
As shown in Fig 12
This technique involves sawing from top to bottom with the
underside of the saw rail.
The chain saw pushes the product forwards and away from the
user. This way, the front edge of the product forms a support,
which intercepts forces generated on the log when sawing.
With pull sawing, the user has much more control over the
product and is better able to avoid rebounds.
This is therefore the preferred sawing technique.
Tree cutting work
•
Always work on the side opposite the branch in question.
•
Begin at the bottom of the trunk and work upwards.
•
When separating thicker branches, make the first cut from below(1). Then cut through from
above(2) and finally separate the remaining stump(3)
