SAFETY INSTRUCTIONS
•
Keep the chain’s cutting teeth properly sharpened!
Follow our instructions and use the recommended
fi
le
gauge.
A damaged or badly sharpened chain increases
the risk of accidents.
•
Maintain the correct raker clearance! Follow our
instructions and use the recommended raker gauge.
Too large a clearance increases the risk of kickback.
•
Keep the chain properly tensioned!
If the chain is slack
it is more likely to jump off and lead to increased wear on
the bar, chain and drive sprocket.
•
Keep cutting equipment well lubricated and properly
maintained!
A poorly lubricated chain is more likely to
break and lead to increased wear on the bar, chain and
drive sprocket.
Cutting equipment designed to minimise
kickback
The only way to avoid kickback is to make sure that the
kickback zone of the bar never touches anything.
By using cutting equipment with ”built-in” kickback reduction
and keeping the chain sharp and well-maintained you can
reduce the effects of kickback.
Bar
The smaller the tip radius the smaller the kickback zone and
the lower the chance of kickback.
Chain
A chain is made up of a number of links, which are available
in standard and low-kickback versions.
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.
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.
!
WARNING! Faulty cutting equipment or the
wrong combination of bar and chain
increases the risk of kickback! Use only the
bar and chain combinations that we
recommend. See the Technical data section.
