The hammer is designed to be used in breaking concrete, road surface or asphalt,
hard or frozen ground. It can be also used in breaking moderate sized boulders as
well as in demolishing reinforced structures and for major excavation and clearing
work. Your local dealer will gladly give you more information.
Principle of installation
Almost all carriers meeting mechanical and hydraulic requirements can be used to
operate the attachment. See “Hammer specifications” on page 66. The product is
installed on the carrier much in the same manner as installing a bucket or other
attachments. A flange mounted attachment requires a separate mounting bracket.
If the carrier has already auxiliary hydraulic circuit, the installation requires only
suitable hoses and fittings. If the carrier does not have suitable kit to run the
attachment, one must be built. This may require installation including new piping
and additional valves such as directional valve and pressure relief valve.
Suitable kits can be ordered from the local dealers, from carrier manufacturers and
their dealers or from third party suppliers.
Hydraulic oil
In general the hydraulic oil originally intended for the carrier can be used with this
product. See “Requirements for hydraulic oil” on page 46.
Operating temperature
The operating temperature is -20 °C (-4 °F) to 80 °C (176 °F). If the temperature is
lower than -20 °C (-4 °F), the hammer and tool have to be preheated before any
operations can begin, in order to avoid breaking the accumulator's membrane and
the tool. During operation they will remain warm.
Note: The temperature of the hydraulic oil must be monitored. Ensure that oil grade
and monitored oil temperature together guarantee correct oil viscosity. See “Oil
specifications” on page 47.
Noise dampening
Operating the hammer near residential areas or other noise sensitive areas can cause
noise pollution. In order to avoid unnecessary noise, please follow these basic rules:
1. When operating with the hammer, keep the tool at 90 degree angle to the
material and the feed force in-line with the tool.
