2Sharpening your chain and adjusting raker clearance

The risk of kickback is increased with a badly sharpened chain!

AGeneral information on sharpening cutting teeth

• Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the cuttings will be very small. If the chain is very blunt it will not produce any cuttings at all, just wood powder.

It is very difficult to sharpen a chain correctly without the right equipment. We recommend you use a file gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain.

The following faults will increase the risk of kickback considerably.

•A sharp chain eats its way through the wood and produces long, thick cuttings.

•The cutting part of the chain is called the CUTTING LINK and this consists of a CUTTING TOOTH (A) and the RAKER LIP (B). The cutting depth is determined by the difference in height between the two.

See the ”Technical data” section for information about sharpening your saw chain.

To sharpen cutting teeth you will need a ROUND FILE and a FILE GAUGE. See the ”Technical data” section for information on the size of file and gauge that are recommended for your saw chain.

1Check that the chain is correctly tensioned. A slack chain is difficult to sharpen correctly.

2Always file cutting teeth from the inside face, reducing the pressure on the return stroke.

File all the teeth on one side first, then turn the saw over and file the teeth on the other side.

3File all the teeth to the same length. When the length of the cutting teeth is reduced to 4 mm (0,16") the chain is worn out and should be replaced.
