Some terms that describe the bar and chain

When the cutting equipment supplied with your saw becomes worn or damaged you must replace it with one of the bars and chains recommended by us. See the Technical data section.

Bar

Length (inches/cm)

Number of teeth on bar tip sprocket (T). Small number = small tip radius = low risk of kickback.

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.

Level of kickback reduction. The level of kickback reduction offered by a chain is only indicated by its model number. See the Technical data section to find the model numbers of chains that are recommended for use with your model of chain saw.

Sharpening your chain and adjusting raker clearance

WARNING! The risk of kickback is increased

!with a badly sharpened chain!

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 cuttings will be very small. If the chain is very blunt it will not produce any cuttings at all. Wood powder would be the only result.

A sharp chain eats its way through the wood and produces long, thick cuttings.

The cutting part of the chain is called the cutting link and this consists of a cutting tooth (A) and the raker lip (B).The cutting depth is determined by the difference in height between the two.
