XVI. Accessories
The "Correct bar and chain combination table" contains a list of all possible combinations
between bar and chain, indicating those which may be used on each machine, marked with
the symbol " ".
The same table also provides the specification data for all chains and bars approved for use on
each machine.
Only use the replacement bars and chains listed in the table. The use of unapproved
combinations may be hazardous and cause serious injuries to operators and damage the
machine.
In consideration that the selection, application and use of the bar and chain are actions
made solely by the user, at his own discretion, the latter assumes responsibility for damages
of any kind arising from such actions. When in doubt or if lacking knowledge of the specifics of
each bar or chain, contact your dealer or Authorised Service Centre.
