SECTION 1.0 INTRODUCTION
This manual contains important informa-
tion for the safe use and maintenance of
the Allied Hole-Hog. Read this manual
thoroughly before installing, operating or
servicing the Hole-Hog. This manual must
be easily accessible to operators or service
and transport personnel. Store this man-
ual in a convenient location.
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
Hole-Hog to conditions beyond its design
capability. Improper operation, service or
the use of non-Allied parts may result in
Hole-Hog failure or personnel injury.
1.1 Safety Information
When using the Hole-Hog, underground
safety procedures such as the location of
existing underground service lines, cables
and conduit must be followed. See Sections
4.0 and 5.0 for further safety guidelines.
Pay particular attention to WARNINGS
and CAUTIONS, identified with this
symbol.
~
These instructions are important for per-
sonnel safety and full service life of the
Hole-Hog. Follow them carefully.
1.2 Warranty Information
Warranty coverage of the Allied Hole-Hog,
depends on proper maintenance and opera-
tion of the Hole-Hog as detailed in this
manual. Improper maintenance or opera-
tion shall void Hole-Hog warranty cover-
age. Immediately upon receipt of the
Hole-Hog, read all Allied warranty docu-
ments delivered with the unit for a thor-
ough understanding of warranty coverage.
Record the Hole-Hog Serial Number in the
space provided above.
1.3 Allied Product Policies
Allied reserves the right to make modifica-
tions to the design or changes to the specifi-
cations without prior notice.
ALLIED 310 Series Hole-Hogs
05/12/03 1
Hole-Hog Technical Manual: Part Number 002004
This Technical Manual is applicable to Hole-Hog:
Models: 310 and 310-TH
Years of Manufacture: 1993 and beyond
Serial Number(s)_________________________________________
The model and serial numbers are located on the ID Plate
mounted on the Hole-Hog as shown in Section 3.3 Decal
Identifcation. The serial number is also stamped on the striker.

In this manual, Allied recommends
Hole-Hog applications, maintenance and
service consistent with industry practices.
Allied takes no responsibility for the re-
sults of actions not recommended in this
manual and specifically the results of:
•Operation in non-recommended applica-
tions
•Incorrect operation
•Improper maintenance
•Use of service parts not approved or sup-
plied by Allied.
These exclusions apply to damage to the
Hole-Hog, associated equipment, and in-
jury to personnel.
ALLIED 310 Series Hole-Hogs

SECTION 2.0 OVERVIEW
The Allied 310 Series Hole-Hog is a pneu-
matically propelled, reversible, ground
piercing tool designed to pierce continu-
ous, blind horizontal, inclined and vertical
holes in compressible soils. With optional
attachments, the Hole-Hog can also be
used to install or remove rigid pipe from
the ground.
The tool consists of three primary sections:
Body/Anvil, Striker and Tail Assembly. A
simple reversing mechanism allows the op-
erator to easily change the tool’s direction
from forward to reverse.
2.1 Body/Anvil
The body/anvil forms the majority of the
Hole-Hog’s exterior. It consists of the anvil
and the body. Refer to Figure 2-1. The
body/anvil is the ground contact surface.
Wear of this component is expected and
normal. The body is internally threaded at
the rear for attaching the Tail Assembly.
2.1.1 Plain Anvil (310)
The anvil is the conical surface that forms
the front of the body/anvil. The anvil is
pressed into the body, and cannot be re-
moved from the assembled body/anvil.
2.1.2 Threaded Anvil (310-TH)
The Model 310-TH anvil is threaded for
mounting optional accessories that en-
hance operation of the Hole-Hog. Refer to
Section 11.0 for more information on acces-
sories and their functions. When an acces-
sory is not installed, the anvil cap protects
the anvil threads.
2.2 Striker
The striker is moved by air pressure back
and forth within the body. Internally, the
striker impacts either the anvil in the front
or the tail assembly in the rear to propel
the Hole-Hog through the ground.
2.3 Tail Assembly
Except for the Striker, the Tail Assembly
contains all internal operating compo-
nents, including the reversing mechanism.
The external threads of the End Cap se-
cure the Tail Assembly to the Body/Anvil.
The Whip Hose attaches to the Tail Assem-
bly at the other end of the End Cap.
Hole-Hog service and repair require re-
moval of the tail assembly to access the
serviceable parts.
2.3.1 Tapered End Cap Adapter
The Tapered End Cap Adapter is a tapered
cylinder that attaches to the hose end of
the End Cap. The End Cap has internal
threads at the hose end for mounting op-
tional accessories that enhance operation
of the Hole-Hog. Refer to Section 11.0 for
more information on accessories and their
functions. When an accessory is not in-
stalled, the Tapered End Cap Adapter pro-
tects the End Cap threads and the Whip
Hose connection.
2.4 Differences Among Hole-Hogs
2.4.1 Variations by Model
This manual covers both Models of Allied’s
310 Hole-Hog Series: the 310 and 310-TH.
All information in this manual applies to
both models unless specifically noted oth-
erwise. These two models are identical ex-
cept for the provisions for securing
optional attachments to the anvil of the
310-TH.
ALLIED 310 Series Hole-Hogs
05/12/03 3

·Model 310 has a plain anvil with no
Anvil Cap.
·Model 310-TH has a threaded anvil
with a protective Anvil Cap.
2.4.2 Variations by Serial Number
In addition to the difference between the
310 and 310-TH Models, there are three
significant differences among 310-Series
Hole-Hogs separated by Serial Number.
There are two methods for mounting the
Whip Hose, and some models have a nylon
insert to lock the Anvil Cap threads. Three
serial number groups track these differ-
ences:
499 and Below
·Whip Hose Mounting Method 1*
500 through 649
·Whip Hose Mounting Method 2*
650 and Above
·Whip Hose Mounting Method 2 and
·Nylon insert used to lock Anvil Cap
These differences affect only four sections
of the manual:
·Disassembly, Section 8.0
·Assembly, Section 9.0
·Field Maintenance, Section 11.0
·Parts Information, Section 14.0
In these section notations indicate the in-
formation that applies to each serial num-
ber group. The information in the other
sections applies to all Hole-Hogs regardless
of unit serial number.
*For details on the different Whip Hose
mountings and the use of the nylon insert,
refer to Disassembly Section 8.3.
