General Safety Information
WARNING: Before selecting or using this product, it is important that
you read and follow the product warnings and instructions in the Owner's
Manual.
WARNING: Failure or improper use of the Parker Chelsea Electronic
Overspeed Control, Power Take-Offs (P.T.O.s) or related accessories can
cause death, personal injury and property damage. Possible consequences
of failure or improper use of these products include but are not limited to the
following:
• Operators, bystanders or equipment being crushed, impacted or caused
to fall due to the sudden, inadvertent, unintended, uncontrolled or
unexpected movement, stopping or starting of devices such as lifts,
hoists, blowers, augers or pumps which are driven by a P.T.O. This can
occur when the P.T.O. is improperly or unexpectedly engaged or
disengaged.
• Rotating shaft injuries resulting from skin, hands, clothing, hair or the like
getting caught in the rotating shaft connected to a P.T.O. or the rotating
portion of the equipment driven by the P.T.O.
WARNING: Always remember to disengage the P.T.O. when the driven
equipment is not in operation.
WARNING: When the Parker Chelsea Electronic Overspeed
Control is set up in Auto Re-engagement Mode, the P.T.O. will
automatically engage when the engine RPM reaches the lower preset point
thus causing the driven equipment to become operable. The vehicle or
equipment operator must therefore make certain that other persons and
property are not in a position to be crushed, impacted, caused to fall or
otherwise injured when re-engagement occurs.
WARNING: Original equipment manufacturers incorporating the Parker
Chelsea Electronic Overspeed Control into their equipment must undertake a
failure mode and effect analysis (FMEA) to identify potential hazards created
by the Automatic Re-engagement Mode. They must then incorporate fail safe
designs into their equipment to protect operators, other persons and property
from injury associated with unexpected disengagement or re-engagement of
the P.T.O.
