Limit condition criteria.
The criterion for an end-of-life condition of a chainsaw is a condition in which further operation of the chainsaw
is not permitted or considered sub-commercial. For example, excessive wear, corrosion, deformation, aging
or destruction of parts, or their combination, if they cannot be repaired in authorized service centers with
original parts, or if it is economically inexpedient to repair.
Criteria for the limit state of the chainsaw are:
• Deep corrosion and cracks on the surfaces of the load-bearing and body parts;
• Excessive wear or damage to the engine and saw chain drive mechanisms, or a combination of these;
• End of life.
CRITICAL PERSONNEL ACTIONS AND FAILURES
A list of possible malfunctions classied as an incident, accident or critical failure of the equipment and
personnel actions in case of their occurrence is given in the table:
Problem Classication Personnel actions
Reducing the rotation
speed of the working tool.
Incident Contact an authorized service center.
Sparking and/or excessive
vibration.
Accident
Take measures to prevent re. Contact an
authorized service center.
Melting of the plastic. Loss
of structural integrity of
the product.
Critical failure
Take measures to prevent re. Contact an
authorized service center.
The table shows the criteria for the limit states of the power tools (failure indications). If these signs appear, the
product may be considered to have reached a "limiting condition" - a condition of the machine and/or equipment
in which further operation is impractical, or restoration of their serviceable condition is impossible or impractical.
To conrm this condition, the equipment must be taken to an authorized service center for diagnostics.
