SAFETY INSTRUCTIONS

1Cutting equipment designed to minimise kickback

Faulty cutting equipment or the wrong combination of bar and chain increases the risk of kickback. Use only the bar and chain combinations recommended in the ”Technical data” section.

The only way to avoid kickback is to make sure that the kick- back zone of the bar never touches anything.

By using cutting equipment with “built-in” kickback protection and keeping the chain sharp and well-maintained you can reduce the effects of kickback.

A Bar

The smaller the tip radius the smaller the kickback zone and the lower the chance of kickback.

B Saw chain

A saw chain is made up of a number of links, which are available in standard and low-kickback versions.

None

Standard Low-kickback

CUTTING LINK

DRIVE LINK

SIDE LINK

Combining these links in different ways gives different degrees of kickback reduction. In terms of kickback reduction alone, four different types of link are available.

CSome terms that describe the bar and chain

When the cutting equipment supplied with your saw becomes worn or damaged you will need to replace it. Use only the type of bar and chain recommended by us. See the ”Technical data” section to find out which equipment is recommended for your saw.

Bar

• LENGTH (inches/cm)

• NUMBER OF TEETH ON BAR TIP SPROCKET (T). Small number = small tip radius = low-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.

•SAW CHAIN OIL HOLE AND HOLE FOR CHAIN

TENSIONER

The bar must be matched to the chain saw design.

Saw chain

• SAW CHAIN PITCH (=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 indicated by its model number.

See the ”Technical data” section to find the model numbers of chains that are recommended for use with your saw.
