1. INTRODUCTION.
This section provides installation and oper-
ation requirements for the Paving Breaker
Models PB35A, PB35AS & PB50A, PB50AS.
2. AIR REQUIREMENTS.
An air compressor of sufficient capacity is
needed to provide the necessary volume of air
at the most efficient operating pressure to en-
sure effective and economical operation of the
paving breaker. Refer to Section 5, Paragraph
3 for air requirements of the paving breakers.
The figures represent air pressures at the
paving breaker inlet and not at the compres-
sor. There is always a certain amount of pres-
sure drop between the compressor and the
paving breaker; only the pressure and volume
at the tool is effective in doing work. If the hose
is relatively short and in good condition, the
pressure drop between the compressor (or air
receiver) and the paving breaker should not
exceed 15 percent of the initial pressure.
Low or inadequate air pressure at the pav-
ing breaker is costly and wasteful, and an in-
sufficient volume of air will not allow it to oper-
ate efficiently.
3. AIR HOSE AND FITTINGS.
Quality hose designed especially for rock
drill service should be used. It should be con-
structed with an outer covering that resists
abrasive wear, an oil-resistant inner tube and
should be able to withstand the heat of the
compressed air. It should have a working
pressure safety factor of at least 4 to 1 in rela-
tion to burst.
The hose fittings should be kept as tight as
possible and should be in good condition.
Elimination of leakage involves making the air
system tight and then keeping it tight. Air loses
through bad connections and worn hose can
often reach 10 to 20 percent of the total air
compressed. Referto Section 5 for the size air
hose required.
*Always follow manufacturer instructions*
*AAA Rent-All 225-291-1356*

4. BEFORE OPERATION.
a. Determine the method of lubrication to
be used. (Refer to Paragraph 9.)
b. Fill the oil reservoir with rock drill oil
conforming to the physical and chemical prop-
erties listed in Section 5, Table 1.
c. Blow out the main air supply hose to get
rid of moisture, rubber particles, and dirt.
d. When using new air hose, blow lubri-
cated air through the hose to completely coat
the inside with oil. This may take 10to 15 min-
utes.
COMPRESSED AIR IS DANGER-
OUS. WHEN BLOWING OUT AN AIR
HOSE, HOLD IT FIRMLY, AND POINT
IT AWAY FROM PERSONNEL AND
EQUIPMENT. NEVER BLOW YOUR
CLOTHES FREE OF DUST WITH
COMPRESSED AIR.
e. An air line filter can be installed in the
main air supply line to keep dirt from entering
the paving breaker. Air line filters are an ac-
cessory item and must be specially ordered.
f. Connect the leader hose to the air con-
nection on the paving breaker.
BE SURE ALL HOSE CONNECTIONS
ARE TIGHT. A LOOSE HOSE NOT
ONLY CAUSES LEAKS, BUT CAN
COME COMPLETELY OFF THE PAV-
ING BREAKER, WHIP AROUND,
AND INJURE PERSONNEL IN THE
AREA. ATTACH SAFETY CABLES
TO ALL HOSES TO PREVENT INJU-
RY IF A HOSE IS ACCIDENTALLY
BROKEN.
g. Open the latch by pushing the lever
down.
Page 2, Section 4, IM6087ENG
h. Insert the shank end of the paving
breaker tool in the fronthead, and swing the
latch up to lock the tool in the paving breaker.
Refer to Section 5, Paragraph 3 for the correct
paving breaker shank sizes of the model pav-
ing breaker being used.
MAKE SURE THE TOOL IS THE
CORRECT SIZE FOR THE FRONT-
HEAD. DON’T USE A PAVING
BREAKER TOOL THAT IS DULL; IT
WON’T DO AN EFFECTIVE JOB
AND WILL CAUSE UNNECES-
SARY WEAR TO THE BREAKER.
6. CONTROLS.
The paving breaker is controlled by a self-
closing, lever-operated, throttle valve that is
built into the handle:
When air pressure is directed to the paving
breaker, the throttle lever will be in the raised,
or off, position. The paving breaker will not
start until the lever is depressed. The lever will
return to the off position when it is released.
6. OPERATION.
a.
b.
KNOW WHAT IS UNDERNEATH
THE MATERIAL YOU ARE
ABOUT TO BREAK. BE ALERT
FOR ANY EXISTING WATER,
GAS, ELECTRICITY, SEWER,
OR TELEPHONE LINES.
ALWAYS KEEP BOTH HANDS
ON THE HANDLE WHILE OPER-
ATING THE PAVING BREAKER.
*Always follow manufacturer instructions*
*AAA Rent-All 225-291-1356*

c. THE OPERATOR MUST KEEP
HIS LEGS AND FEET CLEAR OF
THE PAVING BREAKER TOOL
TO PREVENT INJURY IF THE
TOOL BREAKS. WHEN A TOOL
BREAKS, THE PAVING BREAK-
ER (WITH A PIECE OF BROKEN
TOOL PROJECTING FROM THE
FRONTHEAD) WILL SUDDENLY
DROP TO THE GROUND.
DO NOT OPERATE THE PAVING
BREAKER WITHOUT A PAVING
BREAKER TOOL IN THE FRONT-
HEAD BUSHING. HOLD THE
TOOL FIRMLY AGAINST THE
WORK.
1. Grip the paving breaker handle with
both hands. Depress the throttle valve lever
with the palm of the hand, and apply firm
steady pressure to the handles. The correct
amount of pressure for maximum efficiency
can be gained only by experience, but gener-
ally the correct pressure is usually recogniz-
able by the rhythmic sound of the exhaust and
maximum breaking action. Insufficient pres-
sure will slow down the paving breaker action.
Do not “ride” the paving breaker with one leg
over the handle.
THE OPERATOR WILL BE SERI-
OUSLY INJURED IF THE TOOL
BREAKS WHILE HE IS RIDING THE
PAVING BREAKER WITH ONE LEG
OVER THE HANDLE.
RIDING THE PAVING BREAKER
HANDLE CREATES EXCESSIVE
PRESSURE ON ONE SIDE OF THE
PAVING BREAKER, THROWING IT
OUT OF ALIGNMENT AND CAUS-
ING UNNECESSARY WEAR ON
INTERNAL PARTS.
2. Immediately after starting the paving
breaker, check for the presence of oil mist at
the exhaust port and on the paving breaker
tool. This is the only assurance that oil is trav-
eling all the way through the breaker. When
checking the paving breaker for proper lubrica-
tion, always put the tool against the work.
3. Release the throttle-valve lever to shut
the paving breaker off.
4. If exhaust freeze-up occurs, add anti-
freeze lubricant directly through the air inlet
connection. Use an anti-freeze lubricant rec-
ommended for air tools.
7. OPERATIONAL TIPS.
For maximum operating efficiency, ob-
serve the following suggestions:
a. Never strike the paving breaker with a
blunt object; the housing may be broken or
damaged.
b. Never attempt major maintenance of
the paving breaker on the job; take it to a repair
shop.
c. Never drag the paving breaker along
the ground; the air ports in the exhaust may fill
with dirt.
d. Always blow out the air supply hose be-
fore connecting it to the paving breaker to re-
move any dirt inside the hose.
e. Always be sure the paving breaker is
well lubricated. Adjust the air line lubricator so

that the paving breaker tool always shows an
oil film. There should be a fine mist of oil com-
ing out of the exhaust port.
f. Always keep rock drill oil in a sealed
container so that it doesn’t get contaminated
with dust or dirt.

excavation as you work down. Otherwise,
you’ll either under-cut or over-cut.
n. When making an excavation to work in,
it’s better to make a larger opening than re-
quired to provide ample working room.
o. Always break any material to the point

breaker tools wrapped in burlap or cloth until
just before you use them. At 0°F (-17.8°C) a
hardened steel tool loses about 80% of its nor-

of “give”. This is accomplished by making sure
you’re breaking the concrete or rock, not just
cracking it; otherwise, you’re not working to the
point of give. Always clear away the rubble as
you’re breaking the concrete, rock, or asphalt.
Uncleared rubble blocks your point of give.
p. Always take the right sized “bite” with
the paving breaker. When starting to work the
paving breaker in a material, experiment to
find the right sized bite for breaking that mate-
rial efficiently.
i. Always keep plastic caps or plugs in all
ports when the paving breaker is not in service.
j. Work to the predetermined line (bound-
ary) and grade (depth). Cut straight and cut
neatly. Toget the exact grade, use a tape mea-
surer or ruler.
k. In certain applications, such as a pipe
job where the grade is critical, it pays to over-
excavate. If you try to excavate exactly to
grade, even a small piece of rock sticking up
will throw the pipe off grade. Toavoid this prob-
lem, excavate a little deeper than grade, then
fill and compact to the correct grade. This is
easier than having to come back and break out
more rock.
If you take bites that are too big, it will be
necessary to pry with the paving breaker tool.
This could break the tool or damage the paving
breaker. The paving breaker is not designed
for prying; it’s designed for breaking. Always
use a pick to pry material free.
If you take bites that are too small, you’ll be
working too slowly, and you’ll have to pick up
and move the paving breaker more than nec-
essary.
8. LUBRICATION.
The paving breaker is initially supplied with
a small amount of lubricating oil in the paving
breaker lubrication reservoir, but should be
checked and filled before use. Always check
the oil level in the reservoir before each start
up.
9. METHODS OF LUBRICATION.
Proper lubrication is the most important
single factor responsible for the service life of
I. Always score a sidewalk or portion of a
slab before breaking it. This is usually done
with a concrete saw, but if it has not been, use
the paving breaker to score the job along the
designated lineto ensure a clean break. When
cutting asphalt, cut all the way through the as-
phalt with each cut, as well as all the way
around the perimeter of the area, before you
break the asphalt out.
m. When excavating to a critical line for in- the pneumatic paving breaker. A paving
stallation of a service, square the sides of the breaker can be severely damaged during the

first few minutes of operation if it is not properly
lubricated.
The lubrication method depends on the ac-
tual operating conditions and customer prefer-
ence.
I
NOTE: While the PB50 series breaker
have a built in oil reservoir, the PB35 series
breakers Do Not. They are lubricated by
using a constant feed air line lubricator.
THE BUILT-IN OIL RESERVOIR IN
THE HOUSING PLUG MUST BE .
CHECKED EVERY TWO HOURS
AND REFILLED AS NECESSARY.
a. The oil reservoir built into the PB50 se-
ries breaker housing plug will provide proper
lubrication. It must be checked every two
hours and refilled as necessary.
b. For intermittent operation with an air
supply hose no longer than 50 ft. (15 m), a
compressor-mounted lubricator may be used.
c. For continuous operation during an
eight hour shift, an Ingersoll-Rand@ air line lu-
bricator, or other constant-feed air line lubrica-
tor, should be installed in the air-supply line
about 11.5 ft. (3.5 m) from the paving breaker.
The lubricator listed in the parts list has a ca-
pacity of 1 U.S. pint (0.47 liters) and will be fur-
nished when it is specially ordered. To adjust
an air line lubricator initially:
1. Turn the lubricator needle valve clock-
wise until it is completely closed, and then turn
the valve counter-clockwise about 3/4 of a
turn off its seat.
2. Almost immediately after starting the
paving breaker, check for the presence of oil at
the exhaust ports and on the paving breaker
tool. When checking the paving breaker for
proper lubrication, always put the tool against
the work.
3. Fine-tune the lubricator needle valve
to provide a light film of oil on the paving
breaker tool and a fine oil mist coming from the
exhaust ports. If there is blue smokecoming
from the exhaust port or oil running down the
tool, the paving breaker is getting too much oil.
Adjust the lubricator for proper rate of feed.
d. Regardless of the method of lubrica-
tion, the lubricating oil reservoir must be filled
with the correct grade of rock drill oil as fre-
quently as is necessary to prevent any possi-
bility of the paving breaker running dry.
e. The supply of lubricant in the housing
plug reservoir should be checked every two
hours of operating time.
f. The oil level in the air line lubricator
should be checked at the beginning of each
eight-hour shift and once during the shift.
g. Every effort must be made to avoid oil
contamination from dirt or other impurities. Oil
should be kept in covered containers and
stored in an area that isrelatively dust free.
h. Before filling the air line lubricator, the
area around the filler plug should be wiped
clean.
10. LUBRICATING OIL SPECIFICATIONS.
Ingersoll-Rand® offers a complete line of
rock drill oil formulated in all types of rock drill
equipment. These oils exceed the oil specifi-
cations listed in Section 5, Table 1.
NEVER ALLOW THE LUBRICATOR
TO BECOME EMPTY AS THE
PARTS WILL BE DAMAGED IF THE
PAVING BREAKER IS OPERATED
WITHOUT LUBRICATION.
Use Section 5, Table 2 for the correct vis-
cosity grade selection to meet your require-
ments and Section 5, Table 3 for selecting the
correct rock drill oil part number.
