Sharpening your chain and adjusting depth gauge setting

GENERAL SAFETY PRECAUTIONS

Bar

•Length (inches/cm)

•Number of teeth on bar tip sprocket (T).

•Chain pitch (inches). The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket.

•Number of drive links. The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket.

•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.

Chain

•Chain pitch (inches)

•Drive link width (mm/inches)

•Number of drive links.

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.

•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).

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

1 Filing angle

2Cutting angle

3File position

4Round 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.

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

WARNING! Departure from the sharpening

!instructions considerably increases the risk of kickback.
