This service manual contains all of the information needed to install, use and maintain the attachment known as an
“HP”, manufactured by Indeco Ind. S.p.A., Zona Industriale Bari (BA), Italy.
Vital tools for anyone working in the demolition or recycling sectors, they are specifically designed for light or heavy
demolition work. This publication is aimed at end-users, i.e. anyone whose job description requires them to provide
training instructions or to operate the attachment, including:
Executives
Operations area supervisors
Department heads
Operators directly involved in the transport, storage, installation, use and maintenance of attachments from the
moment they enter the marketplace until they are sent for scrap
Private users
Many of the accidents which occur when servicing and maintaining hammers are caused by not observing the
instructions provided by the manufacturer for such operations. Before carrying out any operations on the product,
read this instruction manual carefully. This document is to be regarded as an integral part of the attachment, and
must be kept for future reference until the attachment itself is finally dismantled. Correct positioning of the HP hammer
is vital in order to ensure optimum working conditions.
