SAFETY INSTRUCTIONS

When you sharpen a cutting tooth there are five important factors to remember.

1 Filing angle

2Cutting angle

3File position

4Round file diameter

5File depth

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

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

WARNING! The following faults will increase

!the risk of kickback considerably: File angle too large

Cutting angle too small

File diameter too small

Sharpening cutting teeth

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 the chain fitted to your chain saw.

•Check that the chain is correctly tensioned. A slack chain will move sideways, making it more difficult to sharpen correctly.

•Always file cutting teeth from the inside face. Reduce the pressure on the return stroke. File all the teeth on one side first, then turn the chain saw over and file the teeth on the other side.

•File 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.

General advice on setting raker clearance

•When you sharpen the cutting teeth you reduce the raker clearance (=cutting depth). To maintain optimal cutting performance you must file back the raker lip to the recommended height.

See the Technical data section to find the raker clearance for your particular chain.

•On a low-kickback cutting link the front edge of the raker lip is rounded. It is very important that you maintain this radius or bevel when you adjust the raker clearance.
