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.
uOperate and maintain the machine as recommended
in the operating and safety instructions
uSelect, maintain and replace consumables/ working
tools/ other accessories as recommended in the op-
erating and safety instructions. Incorrect selection or
lack of maintenance of consumables/ inserted tools/

the worksite, and shower and change into clean
clothes before leaving the worksite to reduce expo-
sure of dust and fumes to yourself, other persons,
cars, homes, and other areas.
uAvoid eating, drinking, and using tobacco products in
areas where there is dust or fumes.
uWash your hands and face thoroughly as soon as
possible upon leaving the exposure area, and always
before eating, drinking, using tobacco products, or
making contact with other persons.
uComply with all applicable laws and regulations, in-
cluding occupational health and safety regulations.
uParticipate in air monitoring, medical examination
programs, and health and safety training programs
provided by your employer or trade organizations
and in accordance with occupational health and
safety regulations and recommendations. Consult
with physicians experienced with relevant occupa-
tional medicine.
uWork with your employer and trade organization to
reduce dust and fume exposure at the worksite and
to reduce the risks. Effective health and safety pro-
grams, policies and procedures for protecting work-
ers and others against harmful exposure to dust and
fumes should be established and implemented
based on advice from health and safety experts.
Consult with experts.
uResidues of hazardous substances on the machine
can be a risk. Before undertaking any maintenance
on the machine, clean it thoroughly.

your way or in any other person's way.
uAlways make sure you are in a stable position with
your feet as far apart as your shoulder width and
keeping a balanced body weight.
WARNING Motion hazards
When using the machine to perform work-related activi-
ties, you may experience discomfort in the hands, arms,
shoulders, neck, or other parts of the body.
uAdopt a comfortable posture while maintaining se-
cure footing and avoiding awkward off-balanced pos-
tures.
uChanging posture during extended tasks may help
avoid discomfort and fatigue.
uIn case of persistent or recurring symptoms, consult
a qualified health professional.
WARNING Vibration hazards
Normal and proper use of the machine exposes the op-
erator to vibration. Regular and frequent exposure to vi-
bration may cause, contribute to, or aggravate injury or
disorders to the operator’s fingers, hands, wrists, arms,
shoulders and/or nerves and blood supply or other body
parts, including debilitating and/or permanent injuries or
disorders that may develop gradually over periods of
weeks, months, or years. Such injuries or disorders may
include damage to the blood circulatory system, damage
to the nervous system, damage to joints, and possibly
damage to other body structures.
If numbness, persistent recurring discomfort, burning
sensation, stiffness, throbbing, tingling, pain, clumsiness,
weakened grip, whitening of the skin, or other symptoms
occur at any time, when operating the machine or when
not operating the machine, stop operating the machine,
tell your employer and seek medical attention. Continued
use of the machine after the occurrence of any such
symptom may increase the risk of symptoms becoming
more severe and/or permanent.
Operate and maintain the machine as recommended in
these instructions, to prevent an unnecessary increase
in vibration.
The following may help to reduce exposure to vibration
for the operator:
uLet the machine do the job. Use a minimum hand
grip consistent with proper control and safe opera-
tion.
uIf the machine has vibration absorbing handles, keep
them in a central position, avoid pressing the handles
into the end stops.
uWhen the percussion mechanism is activated, the
only body contact with the machine you should have
are your hands on the handle or handles. Avoid any
other contact, for example supporting any part of the
body against the machine or leaning onto the ma-
chine trying to increase the feed force. It is also im-
portant not to keep the start and stop device en-
gaged while extracting the machine from the broken
work surface.
uMake sure that the working tool is well-maintained ,
not worn out, and of the proper size. Working tools
that are not well-maintained, or that are worn out, or
that are not of the proper size result in longer time to
complete a task (and a longer period of exposure to
vibration) and may result in or contribute to higher
levels of vibration exposure.
uImmediately stop working if the machine suddenly
starts to vibrate strongly. Before resuming the work,
find and remove the cause of the increased vibra-
tions.
uNever grab, hold or touch the chuck, drill stell or drill
bit when using the machine.
uParticipate in health surveillance or monitoring, medi-
cal exams and training programs offered by your em-
ployer and when required by law.
uWhen working in cold conditions wear warm clothing
and keep hands warm and dry.

found on the previous pages of this manual before
operating the machine.
4.1 Design and function
RD 100 is a sturdy and reliable handheld hydraulic rock
drill designed for working together with pusher leg, PL
100, and with power pack, PP 100. The pusher leg sup-
port helps the operator to lift and feed the rock drill dur-
ing the drilling operation.
There are no limitations on the ambient temperature on
the working place as soon as the used hydraulic fluid are
within the needed parameters. The temperature of the
hydraulic fluid and the hydraulic power are regulated by
the PP 100.
RD 100 is designed for drilling of blast holes, anchor
holes, and for test drillings in for example granite and
concrete. It is suited for hole diameters from Ø 25-42
mm (1-111/16 in.) and will, when using hollow drill steels
of the ISO-series 11-17, work efficiently down to a maxi-
mum depth of2.4 m (7.9 ft), depending on the material.
The drilling dust is removed from the drill hole by means
of flushing water.
No other use is permitted. To choose the correct working
tool, see the spare part list.
A built-in torque limiter ensures that the operator can
hold the rock drill, if the drill steel gets stuck.
The rock drill is delivered with tail-hoses with 'Flat-Face'
quick-release couplings for easy connection to the
Epiroc power pack.
4.1.1 Working principle of a rock drill
Impact Feed force Rotation Flushing
4.1.2 Water flushing (RD 100)
Water flushing is used to transport the drill grit out of the
hole and it has also a reducing effect of dust and fumes.
Water flushing is ducted through the anvil to the drilling
steel. The water flushing engages as soon as the rock
drill is turned on. On RD 100 it is also possible to manu-
ally adjust the water flushing flow with a lever and also
manually activate continuous flushing with a lever on the
side of the machine . Note these features are not avail-
able on RD 100 RB.
The water hose is connected via the power pack to the

5 Installation
WARNING Whipping hose
Hoses under pressure can whip uncontrollably if the
hose connection becomes loose. A whipping hose can
cause severe injuries. To reduce this risk:
uTurn of the power pack before loosening the connec-
tion of a hose.
uCheck that the hose and the connections are not
damaged.
uNever carry or drag the machine by the hoses.
5.1 Hoses and connections
CD
E
A
B
A. Power pack, PP 100.
B. Maximum 30 meter (98 ft) hydraulic hose between
the power pack and the rock drill.
C. Water hose connected to the power pack.
D. Oil pressure line.
E. Oil return line.
nCheck that the correct recommended operating pres-
sure is used, 120 bar (1,740 psi).
nWipe all couplings clean before connecting to the ma-
chine.
nCheck that the rock drill is in stop mode before start-
ing the power pack.
5.2 Hoses
The hydraulic hose must be approved for a working
pressure of at least 240 bar (3,480 psi), for connection to
the machine.

Original Instructions
15
Choose the correct dimension and length for the hy-
draulic hose. For hose lengths up to 30 meters, a hose
with a minimum internal diameter of 16 mm (⅝ in.) must
be used. To choose the correct hose, see the spare
parts list.
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 fill up the hydraulic hoses
with oil and circulate it before connecting the rock drill.
Use a pump to circulate the oil, see the spare parts list.
Connect both hoses and make sure that all hose con-
nections are tight. Never carry the machine by the hose.
NOTICE Attach the return line hose and the pressure
line hose according to matching colors. The red color is
for the pressure line, the blue color is for the return line.
5.3 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.
5.4 Hydraulic oil
In order to protect the environment, use of biologically
degradable and flame proof hydraulic oil (HFD-U) is rec-
ommended. No other fluids must be used.
nViscosity (preferred) 40-60 cSt. at working tempera-
ture.
Make sure to only use clean oil and filling equipment.
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 60°C
(140°F).
5.5 Methods to prevent freezing
If the rock drill freeze, never heat it to melt the ice. Al-
ways let the ice melt at room temperature.
Never pour methylated spirits or similar substances into
the rock drill, as they will interfere with the lubrication
and lead to increased wear.
If the temperature is below 0 °C, blow out the water hose
with compressed air before storage to avoid frost expan-
sion.
NOTICE Maximum allowable air pressure is 7 Bar.
5.6 Pressure adjustment
5.6.1 Hydraulic oil pressure
The hydraulic oil pressure is regulated by the PP 100.
Ensure that it can deliver the required oil pressure of
100-120 bar (1,450 – 1,740 psi) to the machine.
nToo high pressure causes rough operation and ex-
cessive wear.
nToo low pressure results in a slow drilling speed.
5.6.2 Water pressure
The water pressure is regulated by the PP 100. The in-
coming pressure to the PP 100 must be between 5 - 7
bar (73 - 102 psi) at a flow rate of 12 l.p.m (2.6 UK gal/
min) to obtain good water flushing and good functionality
on the pusher leg.
5.7 Drill steel
WARNING Running power pack
Changing the drill steel or accessories while the power
pack is running can cause serious injury.
uShut off the power pack and disconnect the hydraulic
hoses during mounting or dismounting of the drill
steel.
uSecure the power pack against involuntary activa-
tion.

Original Instructions
5.7.1 Before fitting the drill steel
Check that the tool shank is of the correct size and
length for the chuck used. The tool shank must be clean
and the drill steel must be in good condition. Tool shanks
which are chipped, rounded, out of square, or too hard
on the striking end will operate inefficiently and cause
premature piston failure.
Inspect the drill steel: A dull drill steel will slow down the
drilling speed and overstrain the drill mechanism. When
changing drill steel make sure that the new one is of the
correct size to follow the previous bore.
Before drilling, check that the flushing hole in the drill
steel is not blocked.
WARNING Ejected drill steel
If the tool retainer on the machine is not in a locked posi-
tion, the drill steel can be ejected with force, which can
cause personal injury.
uNever start the machine while changing the drill
steel.
uBefore changing the drill steel or accessories, stop
the machine and turn off the power source.
uNever point the drill steel at yourself or anyone else.
uMake sure that the drill steel is fully inserted and the
tool retainer is in a locked position before the ma-
chine is started.
uCheck the locking function by pulling the drill steel
outwards forcefully.
WARNING Vibration hazard
Using inserted tools that do not fulfil the criteria men-
tioned below, will result in a longer time to complete a
task, and may result in higher levels of vibration expo-
sure. A worn tool will also cause increased working time.
uMake sure that the inserted tool is well-maintained,
not worn out and of the proper size.
uAlways use a sharp tool in order to work efficiently.
WARNING Injured hands
There is a risk of crushing fingers when changing the
drill steel. To recuce this risk:
uNever inspect, clean, install, or remove the working
tool while the power source is connected.
uNever put the fingers between the drill steel retainer
and the chuck.
CAUTION Hot drill steel
The tip of the drill steel can become hot and sharp when
used. Touching it can lead to burns and cuts.
uNever touch a hot or sharp drill steel.
uWait until the drill steel has cooled down before car-
rying out maintenance work.
NOTICE Never cool a hot insertion tool in water, it can
result in brittleness and early failure.
5.7.2 Changing drill steel
Whenever changing a drill steel the following instructions
must be observed. Also, make sure that the tool retainer
is of the proper size.
1. When removing the drill steel. Push the tool retainer
outwards, ensure that the tool retainer is fully up.
2. Insert the drill steel in the chuck.

6.1.2 Check the drilling equipment
The following checks must be made before start using
the rock drill. All these checks concern the serviceability
of the rock drill. Some concerns safety:
nClean all labels. Replace any that are missing or can-
not be read.
nInspect the hoses generally for signs of damage.
nInspect the drill steel and drill bit for wear and dam-
age. Do not use an excessively worn or damaged drill
steel.
nInspect the tool retainer for wear and function.
nClose the tool retainer.
nCheck that the flushing holes in the drill steel and drill
bit are not blocked, and that the flushing water flows
through without obstruction.
nThe drill steels must be from the same ISO-series, if
different lengths are used in the same drill hole.
nRemove the protective caps from the quickrelease
couplings.
nEnsure that the hydraulic couplings are clean and
fully serviceable.
nEnsure that the hydraulic hoses are filled with oil.
nConnect the machine.
nEnsure that any power source that are planned to
