INTRODUCTION & SCOPE
This manual contains important informa-
tion for the safe use and maintenance of
the Allied Hammer Models AR 48 and AR
62. Read this manual thoroughly before in-
stalling, operating or servicing the ham-
mer. This manual must be easily accessible
to operators, service and transport person-
nel. Store this manual in a convenient loca-
tion. In most cases, illustrations are of a
typical hammer. Where necessary, there is
a view of each individual model covered in
this manual.
~Instructions identified with this sym-
bol are important for personnel safety and
full service life of the hammer. Follow
these instructions carefully.
Pay careful attention to all instructions
and follow all governing regulations. Oper-
ation or service other than in accordance
with these instructions may subject the
hammer to conditions beyond its design ca-
pability. Improper operation, service or
the use of non-Allied parts may result in
hammer failure or personnel injury.

2.1 Introduction
The Allied AR Series hammers are classi-
fied by carrier application:
(1) skid steer loaders
(2) mini-excavators.
Depending on the hammer model, the AR
hammers are compatible with skid steer
loaders and mini-excavators from 3,000
lbs. (1,300kg). The hammers can be in-
stalled on almost any hydraulic system and
can be operated with pump capacities as
low as 4 gpm (15 lpm).
The maximum operating pressure is: AR
48: 1750 (120bar); AR 62: 1900 psi (130
bar).
The hammer is designed to operate with
the carrier’s auxiliary attachment circuit.
If the carrier does not have an auxiliary cir-
cuit, an Allied installation kit is required.
In either case, proper hydraulic flow and
pressure must be delivered by the auxiliary
circuit.
The hammer side plates are pinned to the
hammer with easy-to-remove pins and vi-
bration dampening bushings.
Illustrations are representative of typical
hammers. These illustrations are not to be
used for repair or service.

2.2 Description of Assembly Groups
•Cylinder Head
The cylinder head is the upper hammer
section.
The nitrogen filling and measuring fit-
ting for the precharge chamber is lo-
cated on the cylinder head. Refer to
Figure 2-4.
•Cylinder
The cylinder is the center section of the
hammer between the cylinder head and
the tool holder. These three assemblies
are connected with tension rods.
The pressure connection (from the
pump), labeled IN above the port, and
the return connection (to the tank), la-
beled OUT above the port, are located on
the front of the cylinder body. Refer to
Figure 2-4.

•Piston
The piston reciprocates in the cylinder
transferring its energy to the demolition
tool upon impact.
•Tool Holder
The tool holder holds the demolition tool
in place with a retainer pin. A tool bush-
ing and impact ring are located in the
tool holder.
