To sharpen the saw chain

The cutter

The cutter is the cutting part of the saw chain and has a

cutting tooth (A) and depth gauge (B). The cutting depth

of the cutter is made by the difference in height between

the two, the depth gauge setting (C).

Make sure to correctly sharpen the cutting teeth by

using four important criteria:

• File angle

• Cutting angle

• File position

• Round file diameter

To sharpen the cutting teeth

Use a round file and a file gauge to sharpen the cutting

teeth. See

Saw chain filing and saw chain combinations

on page 19

for information on the recommended

dimension of the file and gauge for the saw chain

installed on your product.

1. Make sure that the saw chain has the correct

tension. A chain without the correct tension moves to

one side does and not sharpen correctly.

2. Use the file on all the teeth on one side. Then use

the file on the cutting teeth from the inner face and

decrease the pressure in the reverse direction.

3. Turn the product on the opposite side and use the

file on the teeth.

4. Use the file to keep all teeth the same length.

Replace a worn saw chain when the length of the

cutting teeth decreases to 4 mm (5/32 in).

To adjust the depth gauge setting

Sharpen the cutting teeth before you set the depth

gauge. See

To sharpen the cutting teeth on page 15

After you sharpen the cutting tooth (A), the adjustment

of the depth gauge (C) will decrease. To keep the best

cutting performance, use a file on the depth gauge (B) to

get the recommended depth gauge adjustment. See

Guide bar and saw chain combinations on page 19

find the correct depth gauge adjustment for your chain.
