•
Keep the chain’s cutting teeth properly sharpened!
Follow our instructions and use the recommended file
gauge. A damaged or badly sharpened chain increases
the risk of accidents.
•
Maintain the correct depth gauge setting! Follow our
instructions and use the recommended depth gauge
clearance. 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 reduce 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 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
Some terms that describe the bar and chain
To maintain the safety features of the cutting equipment,
you should replace a worn or damaged bar or chain with a
bar and chain combinations recommended by us.
See instructions under Specifications for a list of replacement
bar and chain combinations we recommend.
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 chainsaw design.
Chain
•
Chain pitch (inches)
•
Drive link width (mm/inches)
•
Number of drive links.
GENERAL SAFETY PRECAUTIONS
WARNING! Faulty cutting equipment or
the wrong combination of bar and saw
chain increases the risk of kickback! Only
use the bar/saw chain combinations we
recommend, and follow the filing instructions. See
instructions under Specifications.
IMPORTANT! No saw chain design eliminates the
danger of kickback
