SAFETY
SUMMARY
The following are general safety precautions that are not related to any specific procedures, and therefore do not
appear
else
where in this publication. These are recommended precautions that personnel must understand
and apply during many
phases
of operation and
maintenance.
Keep the work area clean when maintaining or repairing the
Pakhammer.
Personnel not directly involved in operation or maintenance of the Pakhammer should keep a safe distance from
the
work
area.
Operation of the Pakhammer by unauthorized personnel or minors is
prohibited.
Use the proper tool bit for each
application.
Do not force the tool bit during operation of the
Pakhammer.
Wear proper apparel and safety
goggles.
Use a respirator in
contaminated environments.
During operation, do not over reach. Keep stable footing and balance at all
times
Donot carry the
Pakhammer
by the oiler
hose.
The following warnings and cautions appear in the
text
of
this manual, and are repeated here for
emphasis:
Never point the
Pakhammer
toward yourself
or
other
personnel. Serious injury or possible
death
could
result (Page
2-1)
Springs (40) are compressed within the cylinder (47)
and upon removal of all four screws (25) may project
the shuttle valve assembly (26 through 31) and/or
piston assembly (33 through 36) rearward with
sufficient force to injure personnel. (Page 6-3)
Drycleaning
solvent (P-D-680 Safety or
Stoddard's Solvent)
is potentially
dangerous.
Avoid repeated or prolonged breathing of
vapors
and skin contact with the liquid. Do not
use
near
an open flame, arcing equipment or
other
ignition
sources. Always use eye protection
and
protective
clothing.
Serious injury could occur if compressed air is
directed against the skin. Do not use compressed
air unless the pressure is/has been reduced to 30
psi (2.06 bar) or less When working with
compressed air, always use chip guards, eye
protection and other protective equipment. (Page
6-4)
Do not “trigger” (operate) the Pakhammer unless
the tool bit is held firmly against the work surface
as shown in the depictions of Figure 2-1. Damage
to the Pakhammer will result.

1-1 SAFETY PRECAUTIONS.
Refer to the Safety Summary preceding Chapter
1, General Information and Safety Precautions,
for safety precautions necessary for the
protection of personnel and equipment.
1-2 INTRODUCTION.
This technical manual provides instructions for
the operation, maintenance, repair, and parts
support for the Pakhammer manufactured by
Paratech Incorporated, 1025 Lambrecht Road,
Frankfort, Illinois 60423-1648.
1-3 EQUIPMENT DESCRIPTION.
The Pakhammer is a portable, pneumatic impact
tool designed for forcible entry (piercing, cutting,
and breaking) during firefighting and rescue
operations. The Pakhammer is also designed
for medium duty breaking/breaching of masonry
walls digging/tunneling operations. The
Pakhammer employs operating pressures of 40
to 200 psi (pounds per square inch) (2.8 to 13.8
bar) depending upon the material to be broken,
cut or penetrated. Operating air can be obtained
from any air source such as an air compressor
or a SCBA (self-contained breathing apparatus)
air cylinder. Conservation of operating air is
achieved through air utilization only on the power
stroke with virtually no air loss. An integrated
spring retracts the piston on the return stroke.
The 5.214 inch (132.44 mm) stroke provides
very high impact energy for the size and weight
ofthe Pakhammer. ThePakhammer isdesigned
to use 0.475” (12.07 mm) shank diameter tools
made from S-7 tool steel.

CHAPTER 2
OPERATION
2-1 INTRODUCTION.
The Pakhammer is a portable pneumatic tool,
utilized by a single operator and designed for
forcible entry (piercing, cutting, and breaking)
during firefighting and rescue operations. It may
be activated from any air source (air compressor
or air cylinder) capable of supplying 40 to 200 psi
(2.8 bar to 13.8 bar).
2-2 PREPARATION FOR USE.
a. Remove the Pakhammer from its
storage container. If the oiler and hose
assembly is not connected, firmly attach
the oiler and hose assembly to the
Pakhammer handle. Do not carry the
Pakhammer by the oiler hose. Verify the
lubricant level in the oiler is proper (one-
half full). If necessary, fill the oiler half-
full with Marvel ®, Air Tool Oil, Turtle
Wax, P.O. Box 247, Westmont, IL
60559-0247 (Paratech PN 550291).
b. Select the proper tool bit for the specific
work to be accomplished. The tool bits
are 0.475” (12.07 mm) shank diameter
made from heat treated S-7 tool steel.
Pull back the tool retainer release ring,
insert the tool bit fully into the retainer
body and the release the release ring.
The release ring should be in the fully
forward position.
c. The Pakhammer is designed to operate
on air pressures between 40 and 200 psi
(2.8 to 13.8 bar). For maximum
efficiency, use only the operating
pressure to accomplish the task.
Excessive pressure can actually hinder
the actual operation and result in
excessive operator fatigue. Refer to
table 2-1 for starting point pressures and
recommended tool bits. Adjust the air
supply pressure regulator for the desired
pressure. Do not exceed the maximum
operating pressure of 200 psi (13.8 bar).
Connect the air supply to the oiler and
hose assembly and turn on the air
supply line valve to apply air pressure to
the Pakhammer.
2-3 CONTROLS AND INDICATORS.
The only control on the Pakhammer is a trigger
lever located in the pistol grip handle. Pull the
spring loaded trigger lever to start operation.
Release the trigger lever to stop operation.
2-4 APPLICATIONS (Refer to Figure 2-1).
a. General air impact hammer – use in
rescue or industry.
b. Rescue/forcible entry – breaks doors,
locks, padlocks, hasps.
c. Extrication – from automobiles, trucks,
buses, transportation accidents.
d. Rescue from entrapped environments –
earthquakes, collapse.
e. Crash rescue from aircraft – cut skins,
spars, canopies.
f. Crash firefighting – piercing application
for dispensing extinguishing agents.
g. Damage control – access to
compartments through watertight doors,
heavy sheet metal.
h. Breaks and punches holes – concrete,
asphalt.
2-5 NORMAL OPERATING PROCEDURE.
Never point the Pakhammer toward yourself or
otherpersonnel. Seriousinjuryor possible death
could result.
Do not “trigger” (operate) the Pakhammer unless
the tool bit is held firmly against the work
surface as shown in the depictions of Figure 2-1.
Damage to the Pakhammer will result.
a. With the tool bit installed, hold the
Pakhammer firmly against the work
surface as shown in the depictions of
Figure 2-1.
b. Pull the trigger lever to operate the
Pakhammer. If “recoil” (Pakhammer
backs off work surface) is experienced,
reduce the operating pressure until the
Pakhammer can be held firmly against
the work surface.
2-1
WARNING
c. During operation, check periodically to
determine
if a
fine misting of oil is present
in the air
exhausting
from the cylinder
ports.
d. To stop the Pakhammer operation, release
the
trigger
lever.
Note: When using the
piercing
applicators,
penetrate
the work
surface BEFORE
connecting
the hose.
This
will
prevent damage
to the hose
coupling from
Pakhammer
vibration.
2-6
SHUTDOWN.
a. At the conclusion of its use, shut off the
external
air
suppl
y
.
b. Hold the tool bit against a working surface
and pull the trigger lever to dissipate air in
the supply
line.
c.
Disconnect the air supply line from the oiler
connec
tion.
d. Perform the after use
maintenance
specified
in
chap
ter 4 and stow the Pakhammer in its
storage case in
a
dry
environment.
