Description

JCB HYDRAULIC BREAKERS HM80 (OPERATOR MANUAL)

This document details the relevant use and maintenance procedures for the JCB hydraulic breakers HM80. The safety information included is directly relevant to operation and maintenance of the hydraulic breakers. General safety information, and that relevant to the carrier machine is not included. For details about safe operation of the carrier machine, see the relevant documents.

Do not attempt to install, operate or maintain any attachment until you have read and understood all relevant operator documentation for both the attachment, and the carrier machine. Pay particular attention to safety information. You must observe all relevant laws and regulations.

Carrier Machine Suitability

The JCB hydraulic breakers HM80 is suitable for use with a range of JCB Micro Excavators as detailed in Specifications.

The carrier machine must be installed with a hammer circuit. An installation kit, suitable hanger bracket and a hose kit are available from your JCB Distributor.

The HM80 is suitable for use with some other non JCB carrier machines. See the specification section for details of typical carrier requirements. Contact JCB Distributor for advice.

Hydraulic Installation

Check the normal width of the hydraulic lines on existing hydraulic systems. All feed and return lines for the hydraulic oil must have a sufficient inside diameter. Refer to Technical specifications.

The safety facilities on the hydraulic system must be checked by a professional/authorised persons for their quality (CE mark etc.), suitability and proper functioning prior to their first use. By checking the setting of and, where possible, attaching a lead seal to the pressure limiting valve, it can be guaranteed that the system’s working pressure, laid down in accordance with Technical Specifications, can never be exceeded.

The return line from the breaker must run direct to the oil tank in order to guarantee a reliable return oil flow. The pressure-relief overflow line must run direct from the pressure-relief valve to the tank to ensure the reliable functioning of the valve. Do not run any hydraulic lines for attachment of the hydraulic breaker through the driver’s cab!

Removal of the Attachment

Removal of the JCB hydraulic breakers HM80 from the carrier is effected in reverse order to installation. General safety when removing the attachment:

– Collect any oil which runs out and dispose of it in accordance with the applicable statutory provisions to avoid environmental hazards.
– Keep your hands away from bores and fitting surfaces when dismounting the hydraulic breaker.
– Do not touch any parts when the boom or arm is moving.

Short Period of Non-Use

Lengthy Period of Non-Use
