This qualification is about the maintenance of a chainsaw and cross-cutting trees at ground level. Chainsaws used in aerial and ground work are covered. This work will be carried out in a workshop or a woodland environment. “Routine” in this standard means corrective and preventative maintenance that is carried out daily or at regular intervals by the operator prior to and during work.
Cross-cutting operations will include cross-cutting timber under tension in the form of fallen branches, tops, tree sections, severed uprooted stems, horizontal stems, or any timber in a similar situation. This describes the cross-cutting of trees or timber into either manageable sections or to a given length and diameter specification, either where trees have been felled (“at stump”), or at a conversion point to where trees or timber have been extracted. Cross-cutting operations are often carried out in conjunction with the snedding or de-limbing process. Timber under low and moderate tension is covered, but not timber under the extreme tensions found in e.g. windblown trees. The severing of root-plates is excluded.
The felling technique will be appropriate to tree size, weight, condition and species as well as taking into account guidebar size and weather conditions. This covers both coniferous and broadleaved trees, trees that are upright, trees that are weighted towards and that are weighted against a given felling direction. If you are working with chemicals or machinery you need to be appropriately trained or certificated in line with current legislation.
This standard is for those using chainsaws.
