Chainmaintenance
| Sharpening | |
| Never cut with a dull saw chain. A chain which does not cut | |
| unless you press it hard against the wood is damaged, dull or | |
| incorrectly filed. In order to file the chain correctly you need: | |
| round file (A), file gauge (B), flat file (C) and a depth gauge tool | |
| (D). By using the correct file size (see the table) and an file gauge | |
| with a marked filing angle, it is easier to receive a good result. | |
| NOTE! Check that the drive link does no?have a too large play in | |
| the bar groove. This can give an incorrect filing result. Always file | |
| from the inside of the teeth and out. Then turn the saw and file on | |
| the other side. In order to receive a straight cut in the wood, all | |
| the teeth should be filed to the same length. If the chain is filed | |
| regularly, only a few strokes are needed on every saw tooth. For | |
| the best performance, every chain type has different cutting | |
— | angles, file sizes and filing depth (see the table). | |

~WARNING! If a too small filing size is used or the file is kept too deep in the cutting tooth, the chain will be dangerously
| aaoressive. This means that |

Depth gauge
In order to receive the best performance and life time of the chain, always keep the prescribed depth gauge setting.
~WARNING ! A too big depth gauge makes the chain dangerously aggressive. This means that kickback can occur.
