•

Bar groove width (inches/mm). The groove in the bar 
must match the width of the chain drive links.

•

Chain oil hole and hole for chain tensioner. The bar 
must be matched to the chain saw design. (16)

•

Chain pitch (inches) (15)

•

Drive link width (mm/inches) (18)

•

Number of drive links. (17)

•

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 chips will be very small. If the chain 
is very blunt it will produce wood powder and no chips 
or shavings.

•

A sharp chain eats its way through the wood and 
produces long, thick chips or shavings.

•

The cutting part of the chain is called the cutter and 
consists of a cutting tooth (A) and the depth gauge 
(B). The cutters cutting depth is determined by the 
difference in height between the two (depth gauge 
setting). (23)

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

1

Filing angle (21)

2

Cutting angle (20)

3

File position (22)

4

Round file diameter

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. (22)

See instructions under the heading Technical data for 
information about sharpening your chain.

To sharpen cutting teeth you will need a round file and a 
file gauge. See instructions under the heading Technical 
data 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 (5/32") the 
chain is worn out and should be replaced. (23)

•

When you sharpen the cutting tooth (A) the depth 
gauge setting (C) will decrease. To maintain optimal 
cutting performance the depth gauge (B) has to be 
filed down to achieve the recommended depth gauge 
setting. See instructions under the heading Technical 
data to find the correct depth gauge setting for your 
particular chain. (24)

•

The cutting teeth should be newly sharpened before 
adjusting the depth gauge setting. We recommend 
that you adjust the depth gauge setting every third 
time you sharpen the cutting teeth. NOTE! This 
recommendation assumes that the length of the 
cutting teeth is not reduced excessively.

•

You will need a flat file and a depth gauge tool. We 
recommend that you use our depth gauge tool to 
acheive the correct depth gauge setting and bevel for 
the depth gauge.

•

Place the depth gauge tool over the chain. Detailed 
information regarding the use of the depth gauge tool, 
will be found on the package for the depth gauge tool. 
Use the flat file to file off the tip of the depth gauge that 
protrudes through the depth gauge tool. The depth 
gauge setting is correct when you no longer feel 
resistance as you draw the file along the depth gauge 
tool. (24)

The more you use a chain the longer it becomes. It is 
therefore important to adjust the chain regularly to take up 
the slack.
