GENERAL SAFETY PRECAUTIONS
English

11
•
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
Jonsered. See instructions under the heading Technical
Data 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.
!
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 the
heading Technical data.
IMPORTANT! No saw chain design eliminates the
danger of kickback.
!
WARNING! Any contact with a rotating
saw chain can cause extremely serious
injuries.
