FILING CHAIN

General instructions regarding cutters

•Never cut wood using a dull chain. Having to press hard is a sure sign of a dull chain, as are very small chips. A very dull chain will produce sawdust rather than chips.

•A sharp chain will produce large chips, and the saw will feed itself through the wood.

• The part of the chain that saws is called the CUTTING LINK, which consists of a CUTTER (A) and DEPTH GAUGE (B). The difference in height between them determines the depth of the cut.

• When filing a saw, pay close attention to:

TOP-PLATE ANGLE

CUTTING ANGLE

HORIZONTAL FILE ANGLE

FILE DIAMETER

FILE DEPTH

See «Technical Specifications» for the details which apply to your chain. It is very difficult to file a chain saw correctly with- out the proper aids. We recommend the use of a file guide to ensure maximum cutting efficiency with the least tendency to kickback.

Filing cutters

To file cutters correctly, a ROUND FILE and a FILE GUIDE are required. Look under «Technical Specifications» for the correct file diameter and file guide for your saw and chain.

• File only with the chain properly tensioned. A loose chain wiggles, making it difficult to file.

• Always file from the inside of each cutter towards the outside. Lift the file on the return stroke.

• File the cutters on one side first. Then turn the saw around and file the cutters on the other side.

• Make certain that all cutters are of equal length. When the horizontal length is down to 3 mm (1/8”), the chain is worn out and must be dis- carded.

CAUTION!

Improperly filed cutters heighten kickback tendencies!

LIMBING

CAUTION!

Most kickback accidents take place when limbing. Pay very close attention to the kickback danger zone when cutting limbs under tension!

All the principles which apply to crosscutting also apply when cutting thick branches.

Cut complicated branches in several stages.

Ensure that your footing is secure at all times, whether moving about or standing in one place. Always work with the log to your right. For best control, hold the chain saw as close to your body as possible.
