1.2 RESPONSIBILITY AND GUARANTEE
These operatng nstructons are addressed to persons, who are well acquanted wth the assembly of eleva-
tors. Thorough knowledge of the elevator constructon and mantenance are necessary.
The firm P.F.B. declnes any responsblty for damages, dervng from not workmanlke or smlar actons, that
have not been carred out accordng to the followng operatng nstructons and that therefore may damage the
characterstcs of the product.
P.F.B.’s guarantee may not be vald f the component part s used n a dfferent way than that descrbed n these
nstructons.
For techncal securty reasons, t s not allowed:
• assemblng of wrong overspeed governors, or governors destned to other applcatons than the ntended one
• ntroducton of changes of any knd to the overspeed governor.
1.3 SAFETY PRECAUTIONS
Generally the fitters are themselves responsble for the safety of the work.
The observance and respect of all the safety regulatons n force and the legal rules are necessary to avod da-
mages to persons and to the product durng the assembly, mantenance and repar.
Instructons that should be partcularly consdered regardng safety and damage preventon are ponted out
wth the followng symbols:
ATTENTION! Indcaton of danger. It ndcates stuatons, that nvolve rsks for the persons and stres-
ses out behavoural procedures.
DANGER! Indcaton of danger of possble damages to the structural element and to ts component
parts (e.g.: mstakes n the assembly, etc.).
IMPORTANT! Indcaton of useful nformaton.
The followng operatng nstructons are an ntegral part of the whole plant. They must be kept n a protected
and easly accessble place (such as for nstance n the engne room).
1.4 WORKING INSTRUCTIONS ON SAFETY STRUCTURAL ELEMENTS
Overspeed governors belong to the safety structural elements group. It s absolutely necessary to observe the
rules and regulatons that refer to ths structural element, ncludng the nformaton gven n the operatng n-
structons.
For that reason, before begnnng to work on ths component part, the followng operatng must be
red and understood, n partcular wth regard to the chapter concernng “safety precautons”.
Safety devces need partcular attenton. Ther perfect functonng s essental for a safe operaton of the plant.
The regulaton of the safety devces, that can be set only after the assembly, must be carred out mmedately
after the assembly tself.
If safety devces are already preset at the factory, ther operatons have to be mmedately tested.
Should t be necessary to dsassemble the safety devces durng mantenance or repar, when termnated they
have to be mmedately reassembled and adequately tested.
In these nstructons, the followng safety devces are descrbed:
• safety swtch on the overspeed governor (adjusted n the factory)
• safety swtch on the tenson weght wth counterweght (only n the plants that are n conformty wth
EN81).
