1.2 RESPONSIBILITY AND GUARANTEE
These operating instructions are addressed to persons, who are well acquainted with the assembly of
elevators. Thorough knowledge of the elevator construction and maintenance are necessary.
The firm P.F.B. declines any responsibility for damages, deriving from not workmanlike or similar actions, that
have not been carried out according to the following operating instructions and that therefore may damage the
characteristics of the product.
P.F.B.'s guarantee may not be valid if the component part is used in a different way than that described in
these instructions.
For technical security reasons, it is not allowed:
• assembling of wrong overspeed governors,or governors destined to other applications than the intended one

1.3 SAFETY PRECAUTIONS
Generally the fitters are themselves responsible for the safety of the work.
The observance and respect of all the safety regulations in force and the legal rules are necessary to avoid
damages to persons and to the product during the assembly, maintenance and repair.
Instructions that should be particularly considered regarding safety and damage prevention are pointed out
with the following symbols:
ATTENTION! Indication of danger. It indicates situations, that involve risks for the persons and
stresses out behavioral procedures.
DANGER! Indication of danger of possible damages to the structural element and to its component
parts (e.g.: mistakes in the assembly, etc.).
IMPORTANT! Indication of useful information.
The following operating instructions are an integral part of the whole plant. They must be kept in a protected
and easily accessible place (such as for instance in the engine room).
1.4 WORKING INSTRUCTIONS ON SAFETY STRUCTURAL ELEMENTS
Overspeed governors belong to the safety structural elements group. It is absolutely necessary to observe the
rules and regulations that refer to this structural element, including the information given in the operating
instructions.
For that reason, before beginning to work on this component part, the following operating must be
red and understood, in particular with regard to the chapter concerning "safety precautions".
Safety devices need particular attention. Their perfect functioning is essential for a safe operation of the plant.
The regulation of the safety devices, that can be set only after the assembly, must be carried out immediately
after the assembly itself.
If safety devices are already preset at the factory, their operations have to be immediately tested.
Should it be necessary to disassemble the safety devices during maintenance or repair, when terminated they
have to be immediately reassembled and adequately tested.
In these instructions, the following safety devices are described:
• safety switch on the overspeed governor (adjusted in the factory)
• safety switch on the tension weight with counterweight.
