chine is exceeded, the accumulator can be over charged
which can result in material damage and personal injury.
uAlways run the hydraulic machine with the correct
operating pressure. See "Technical data".
DANGER Explosion hazard
If a working tool comes into contact with explosives or
explosive gases, an explosion could occur. When work-
ing on certain materials and when using certain materi-
als in machine parts, sparks and ignition can occur. Ex-
plosions will lead to severe injuries or death.
uNever operate the machine in any explosive environ-
ment.
uNever use the machine near flammable materials,
fumes or dust.
uMake sure that there are no undetected sources of
gas or explosives.
WARNING Trapping hazard
There is risk of neck ware, hair, gloves and clothes get-
ting dragged into or caught by a rotating insertion tool or
accessories. This may cause choking, scalping, lacera-
tions or death. To reduce the risk:
uNever grab or touch a rotating drill steel.
uAvoid wearing clothing, neck ware or gloves that may
get caught.
uCover long hair with a hair net.
WARNING Projectiles
Failure of the work piece, of accessories, or even of the
machine itself may generate high velocity projectiles.
During drilling, splinters, or other particles may become
projectiles and cause bodily injury by striking the opera-
tor or other persons. Also, breakage of the work piece,
accessories, or the insertion tool may generate high ve-
locity projectiles that can cause bodily injury. In addition,
objects falling from a height can cause bodily injury. To
reduce risks:
uClose off the working area.
uBefore starting, make sure that no persons are in the
danger area, 5 meters both horizontally and vertically
from the machine.
uImmediately switch off the machine when persons
are present in the danger area.
uNever operate unless the inserted tool is retained in
the machine with a proper tool retainer.
WARNING Slipping, tripping and falling hazards
There is a risk of slipping or tripping or falling, for exam-
ple tripping on the hoses or on other objects. Slipping or
tripping or falling can cause injury. To reduce this risk:
uAlways make sure that no hose or other object is in
your way or in any other person's way.
WARNING Dust and fume hazard
Dusts and/or fumes generated or dispersed when using
the machine may cause serious and permanent respira-
tory disease, illness, or other bodily injury (for example,
silicosis or other irreversible lung disease that can be fa-
tal, cancer, birth defects, and/or skin inflammation).
Some dusts and fumes created by drilling, breaking,
hammering, sawing, grinding and other construction ac-
tivities contain substances known to the State of Califor-
nia and other authorities to cause respiratory disease,
cancer, birth defects, or other reproductive harm. Some
examples of such substances are:
uCrystalline silica, cement, and other masonry products.
uArsenic and chromium from chemically-treated rubber.
uLead from lead-based paints.
Dust and fumes in the air can be invisible to the naked
eye, so do not rely on eye sight to determine if there is
dust or fumes in the air.
To reduce the risk of exposure to dust and fumes, do all
of the following:
uPerform site-specific risk assessment. The risk as-
sessment should include dust and fumes created by
the use of the machine and the potential for disturb-
ing existing dust.
uUse proper engineering controls to minimize the
amount of dust and fumes in the air and to minimize
build-up on equipment, surfaces, clothing, and body
parts. Examples of controls include: exhaust ventila-
tion and dust collection systems, water sprays, and
wet drilling. Control dusts and fumes at the source
where possible. Make sure that controls are properly
installed, maintained and correctly used.
uWear, maintain and correctly use respiratory protec-
tion as instructed by your employer and as required
by occupational health and safety regulations. The
respiratory protection must be effective for the type
of substance at issue (and if applicable, approved by
relevant governmental authority).
uWork in a well ventilated area.
uIf the machine has an exhaust, direct the exhaust so
as to reduce disturbance of dust in a dust filled envi-
ronment.

3 Overview
To reduce the risk of serious injury or death to your-
self or others, read the Safety instructions section
found on the previous pages of this manual before
operating the machine.
3.1 Design and function
The mounted posthole borer is a robust and flexible hy-
draulic attachment suitable for all jobs in connection with
setting up of poles, piles, fences etc. and where there is
a need of drilling holes down to a maximum depth of
1.5m (59in.) with standard Epiroc insertion tools in
sizes from ø90 to ø350mm (3.54 - 13.78in.). The post-
hole borer is to be mounted on the shovel or on the arm
of a small skid-steer, excavator or tractor weighing 800 -
3500kg (1800 - 7700lbs). No other use is permitted.
The post hole borer has a clockwise rotation when it is
correctly connected to the carrier's hydraulic system.
The pressure provided by the carriers hydraulic system
must be at maximum 160bar (2320psi).
Never use the posthole borer as a rotation movement
supplier for other equipments. The mounted posthole
borer or the inserted tool must never be used as a lifting
device.
To choose the correct insertion tool, see the spare parts
list or the accessories catalogue.

4.1 Lifting the machine
WARNING Falling machine can cause injuries
uPlace the machine in a safe position where it cannot
fall over and cause damage.
Carefully check that the carrier is stable enough when
transporting or doing maintenance or other work on the
machine.
The machine is delivered in a box. To lift out the ma-
chine in a safe way, fit the lifting strap in the manner
shown in the picture below.
5 Installation
WARNING Whipping hydraulic hose
Hydraulic hoses under pressure can whip uncontrollably
if screws loosen or are loosened. A whipping hydraulic
hose can cause severe injuries.
uDepressurise the hydraulic system before loosening
the connection of a hydraulic hose.
uTighten the nuts on the connections of the hydraulic
hoses to the required torque.
uCheck that the hydraulic hose and the connections
are not damaged.
5.1 Hoses
For connection on the machine, the hydraulic hose must
be approved for a working pressure of at least 172bar
(2500psi) and have a 12.7mm (½ in.) inner diameter.
To resist exterior wear and tear, we recommend using a
2-layer hydraulic hose. The machine connection marked
P (pump) is the oil inlet, and the connection marked T
(tank) is the oil outlet. Always connect both hoses and
make sure that all hose connections are tight. Never
carry the machine by the hose.
5.2 Quick-release couplings
The original hydraulic hoses are fitted with Flat-Face
quick-release couplings that are strong and easy to
clean. The quick-release couplings are fitted so that the
male connection supplies oil and the female connection
receives oil.
NOTICE Wipe all couplings clean before connecting. En-
sure that couplings are clean and correctly engaged be-
fore operation. Failure to do so may result in damage to
the quick couplings and cause overheating and cause
foreign matter to enter the hydraulic system.
5.3 Hydraulic oil
In order to protect the environment, use of biologically
degradable hydraulic oil is recommended. No other flu-
ids must be used.
nViscosity (preferred) 20-40 cSt.
nViscosity (permitted) 15-100 cSt.
nViscosity index minimum 100.
Standard mineral or synthetic oil can be used. Make
sure to only use clean oil and filling equipment.

Safety and operating instructions
12 © Construction Tools PC AB | 9864 0046 01 | 2020-11-13
Original Instructions
When the machine is used continuously, the oil tempera-
ture will stabilise at a level which is called the working
temperature. This will, depending on the type of work
and the cooling capacity of the hydraulic system, be be-
tween 20-40°C (68-104°F) above the ambient tempera-
ture. At working temperature, the oil viscosity must be
within the preferred limits. The viscosity index indicates
the connection between viscosity and temperature. A
high viscosity is therefore preferred, because the oil can
then be used within a wider temperature range. The ma-
chine must not be used, if oil viscosity fails to remain
within the permitted area, or if the working temperature
of the oil does not fall between 20°C (68°F) and 70°C
(158°F).
5.4 Pressure adjustment
The maximum pressure of the power source is impor-
tant. The pressure created in case of an incorrectly or
unfitted return line coupling would cause overloading.
Which could harm the machine and result in bodily in-
juries. The maximum pressure of the power source is
172bar (2500psi) (limited by safety valve adjustment).
WARNING Operating pressure
If the maximum operating pressure for the hydraulic ma-
chine is exceeded, it can result in material damage and
personal injury.
uAlways run the hydraulic machine with the correct
operating pressure, see "Technical data".
uOnly readjust the pressure relief valve (torque con-
trol) on the machine according to procedure and val-
ues described under maintenance. Note that higher
settings might lead to a higher torque, which could
harm the machine and result in serious injury or
death.
5.5 Insertion tool
CAUTION Hot working tool
The tip of the working tool can become hot and sharp
when used. Touching it can lead to burns and cuts.
uNever touch a hot or sharp working tool.
uWait until the working tool has cooled down before
carrying out maintenance work.
WARNING Ejected insertion tool
If the tool retainer on the machine is not tightened, the
inserted tool can be ejected with force, which can cause
personal injury.
uNever start the carrier while changing the insertion
tool.
uShut the carrier's engine off and secure the carrier
and machine against involuntary start before chang-
ing the inserted tool or accessories.
uNever point the inserted tool at yourself or anyone
else.
uMake sure that the insertion tool is fully inserted and
the tool retainer is tightened before the machine is
started.
uCheck the locking function by pulling the inserted tool
outwards forcefully.
5.5.1 Fitting and removing the insertion
tool
WARNING Running engine
Changing the inserted tool or accessories while the car-
rier's engine is running can cause serious injury.
uSecure the carrier against involuntary activation.
Whenever fitting or removing the insertion tool the fol-
lowing instructions must be observed:

6 Operating
6.1 Operating temperatures
The operating temperatures of the hydraulic attachment
are between -20°C (-4°F) and +80°C (+176°F).
CAUTION Temperature hazard
The hydraulic attachment and the hydraulic oil system of
the carrier can be damaged if the hydraulic attachment is
used at higher or lower temperatures.
uOnly start the hydraulic attachment when the hy-
draulic oil has reached the proper operating tempera-
ture.
uIf the ambient temperature is below -20°C (-4°F),
you must warm up the insertion tool and the hy-
draulic attachment before use.
uIf the oil temperature exceeds +80°C (+176°F), you
must not use the hydraulic attachment as the oil
quality becomes inadequate which severely shortens
the life time of seals and O-rings.
6.2 Risk area
Before starting the machine, make sure that no persons
are in the risk area, 5meters (60ft) both horizontally and
vertically from the machine.

7.2 Periodic maintenance
After each operating period of approximately 300 work-
ing hours or twice a year the machine must be disman-
tled and all parts be cleaned and checked. This work
must be performed by authorised staff, trained for this
task.
8 Storage
WARNING Falling machine can cause injuries
uPlace the machine in a safe position where it cannot
fall over and cause damage.
If the machine is not used for a long time, the following
points have to be considered to protect the machine
from corrosion:
nClean the machine carefully.
nStore the machine in a dry place.
9 Disposal
A used machine must be treated and scrapped in such a
way that the greatest possible portion of the material can
be recycled and any negative influence on the environ-
ment is kept as low as possible.
Before a used machine is scrapped it must be emptied
and cleaned from all hydraulic oil. The remaining hy-
draulic oil must be deposited and any negative influence
on the environment is to be kept as low as possible.

LPHB-M
Sound pressure 1 dB(A) <70
1 Sound pressure level according to EN ISO 3744 in accordance with directive 2000/14/EC at 10 metres distance.
These declared values were obtained by laboratory type testing in accordance with the stated directive or standards and
are suitable for comparison with the declared values of other tools tested in accordance with the same directive or stan-
dards. These declared values are not adequate for use in risk assessments and values measured in individual work
places may be higher. The actual exposure values and risk of harm experienced by an individual user are unique and de-
pend upon the way the user works, in what material the breaker is used, as well as upon the exposure time and the
physical condition of the user, and the condition of the breaker.
We, Construction Tools PC AB, cannot be held liable for the consequences of using the declared values, instead of val-
ues reflecting the actual exposure, in an individual risk assessment in a work place situation over which we have no con-
trol.
