Chainsaws can be broadly divided into the following groups:
1. PROFESSIONAL SAWS Chainsaws with maximum performance and optimum ergonomics. Designed for professional full-time or part-time use. Also available with heated handles.
2. ALL-ROUND SAWS Robust chainsaws. Built as professional saws, but with a slightly lower performance. Designed for part-time use, such as for woodcutting.
3. RECREATIONAL/CONSUMER SAWS Easy to use, small saws designed for home use by “recreational users” who do not use their chainsaw very often.
4. TREE CARE SAWS Developed to be used only by professionals in tree care work. Handling and work techniques for these saws are not addressed in this manual.
The size of the chainsaw is determined by piston displacement (cm³) and engine power (hp and kW). The size you should choose depends on the following two factors:
PROFICIENCY AND EXPERIENCE Choose a smaller chainsaw with a less powerful engine if you are new to chainsaw work. A small saw is more manoeuvrable than a large one. If the chainsaw is too heavy, your hands and arms will tire, which in the long run represents a safety risk.
WOOD TYPES AND SIZE OF TREES Choose a larger chainsaw with more power if you want to fell larger trees, especially hardwood. If the model is too small, this will subject the chainsaw to great strain and unnecessary wear.
Guide bar length
The appropriate length of the guide bar is determined by tree size and to some extent by the level of expertise the user has. If you are used to handling a chainsaw, you should have access to at least two different guide bar lengths, allowing you to vary the guide bar length with different tree sizes. A shorter guide bar weighs less and is easier to manoeuvre when doing limbing work. A longer guide bar is used for larger tree sizes.
