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
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
None | Standard |
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.
Kickback reduction | Cutting link | Drive link | Side link |
LOW
STANDARD
HIGH
EXTRA HIGH
C Some 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 =
• 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.
