Sharpening your chain and adjusting

depth gauge setting

General 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 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. (Figure 18)

• 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). (Figure 19)

When you sharpen a cutting tooth there are four important

factors to remember.

1 Filing angle (Figure 20)

2 Cutting angle (Figure 21)

3 File position (Figure 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.

(Figure 23)

See instructions under the heading Technical data for

information about sharpening your chain.

Sharpening cutting teeth

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. (Figure 24)

• 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. (Figure 20)

• 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. (Figure 25)

General advice on adjusting depth gauge setting

• 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. (Figure 26)

Adjustment of depth gauge setting

• 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. (Figure 27)

Tensioning the chain

The more you use a chain the longer it becomes. It is

therefore important to adjust the chain regularly to take up

the slack.

Check the chain tension every time you reﬁll with saw

chain oil. NOTE! A new chain has a running-in period

during which you should check the tension more

frequently.

Tension the chain as tightly as possible, but not so tight

that you cannot pull it round freely by hand. (Figure 47)

• Release the knob by folding it out until it snaps open.

(Figure 28)

• Turn the knob anti clockwise to loosen the drive

sprocket cover. (Figure 29)

• Adjust the tension on the chain by turning the chain

tensioner wheel down (+) for tighter tension and up (-

) to loosen the tension. (Figure 30)

• Tighten the bar clutch by turning the knob clockwise.

(Figure 31)

Always wear gloves, when working with

the chain.

WARNING! Departure from the

sharpening instructions considerably

increases the risk of kickback.

WARNING! The risk of kickback is

increased if the depth gauge setting is

too large!

WARNING! A slack chain may jump off

and cause serious or even fatal injury.

WARNING! Always remove the battery

before any assembly, maintenance and/

or checking is done on the machine.
