Lubricant recommendation
Use a mineral-based air tool oil
Ambient temperature ºC Viscosity grade (ISO 3448)
-30 to 0 ISO VG 32-68
-10 to +20 ISO VG 68-100
+10 to +50 ISO VG 100-150
4� Air/water pressure and hose dimensions
Air pressure
Ensure that the compressor can deliver the required air pressure
of 5 bar at the machine�
• High pressure (>6�3 bar) causes rough operation and damage�
• Low pressure (<4 bar) results in a slow drilling speed�
Water pressure
Make sure that the water pressure is set to around 3 bar�
Note! Maximum water pressure is 1 bar less than the working
pressure� For example if the air pressure is 5 bar, the water pres-
sure must be below 4 bar to prevent water entering the impact
mechanism�
Note! Dry drilling is strictly prohibited� Operation without air- and
water tubes is not allowed as it will result in poor drilling perfor-
mance�
Hose dimensions
The air hose diameter must be no less than 25mm� Inner diameter
of connection nipple and hose must be no less than 19mm�The
ideal overall air hose length is less than 15m�
Drill steel
Ejected insertion tool�
WARNING
If the tool retainer on the machine is not in a locked position, the
inserted tool can be ejected with force, which can cause personal
injury�
• Before changing the insertion tool, stop the machine, switch off
the compressed air supply and bleed the machine by activating
the start and stop device�
Before fitting the insertion tool
Check that the tool shank is of the correct size and length for the
chuck used�The shank must be clean and the tool must be in good
condition� 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 the correct size to follow your previous bore�
Before drilling, check that the flushing hole in the drill steel is not
blocked�

To avoid injury, before using or servicing tool, read and under-
stand separately provided safety instructions�
Operation
Using the rock drill for the first time
When the rock drill arrives from the factory, the inside of the tool
is coated with heavy oil to prevent corrosion�
After unpacking and installing the tool, pour a small amount of lu-
brication oil into the air connection and operate the tool on partial
throttle to clean the interior� Follow this immediately with a liberal
amount of air tool oil�
The rock drill and pusher leg are lubricated with oil mixed with
compressed air, which is taken to the parts that need continu-
ous lubrication� Oil is metered into the compressed air using the
FY250 lubricator connected to the air line�
Preparations before starting
1� Check the drilling equipment
• Check that all of the drilling equipment is in good working order�
• Check that the impact surface of the drill steel shank is flat with
no signs of wear�
• Make sure that the air inlet and exhaust ports are free from
obstructions�
• Check that the flushing holes in the drill steel and drill bit are
not blocked and that the flushing air/water flows through without
obstruction�
• Ensure that the fittings are tight and leak-proof�
Always check for damaged or loose hoses and fittings before
operation�Whipping hoses can cause serious injury�
WARNING
2� Blow out the air hose
Every day before using the drill, blow out the air hose to clear it
from accumulated dirt and moisture�
3� Fill the lubricator with oil
• Fill the lubricator (located on top of the cylinder) with oil if nec-
essary�The rock drill is lubricated with oil mixed with compressed
air, which is taken to the parts that need continuous lubrication�
Oil is metered into the compressed air�
• Use Atlas Copco Rock Drill AIR-OIL as a lubricant�

Harder end face will cause piston damaged and breakage of the
end face of the piston� If the shank face is too soft, it will be easily
deformed by the piston, which will result in difficulty in removing
the working tool�
• Shank end face shall be flat and perpendicular to the axis�
• Remove sharp edges from the shank's end face� Rough shank
surface will cause premature piston failure�
• Inspect the bits: Dull bits will slow down the drilling speed and
overstrain the drill mechanism� When changing bits make sure
that the new bit is the correct size to follow your previous bore�
• Before drilling check that the flushing hole in the working tool is
not blocked�
Fitting the working tool
1� Push the retainer outwards in the direction of the arrow (see
picture below), until the front portion of the retainer is able to ac-
commodate the working tool collar�
2� Insert the drill in the chuck�
3� When the drill bottoms, push back the retainer to lock it�
Removing the working tool
1� Push the retainer outwards in the direction of the arrow until the
working tool collar disengages from the front of the retainer�
2� Pull the working tool out�
3� Push back the retainer�
Attaching the pusher leg to the rock drill
• Mount the pusher leg (1), lock sleeve (2), rubber pad (3), washer
(4) and locking nut (5) in the order shown in the picture below�
•Turn the locking nut clockwise with a wrench until you hear a
"click"�
Controls
Throttle lever
The rock drill is equipped with a throttle lever for regulating both
the compressed air to the percussion mechanism and the flushing
water�
A� Extra blowing, water flushing off, impact and rotation off�
B� Stop position, air and water off
C� Low throttle, air to pusher leg, water flushing
D� Medium throttle
E� Full throttle
Feed control
Adjust the feed force by means of the feed control lever as fol-
lows:
A� Extra blowing, water flushing off, impact and rotation off�
B� Stop position, air and water off
Trigger
When the trigger (A) is pushed in, the feed force stops abruptly
and the setting on the feed control lever is overridden�The piston
rod in the pusher leg retracts automatically�This function is used
for example to adjust the height of the rock drill, when rigging up

11
the pusher leg, or when there is a tendency to jam� When the trig-
ger is released, the feed control setting is activated again�
Oil regulating valve
Oil dosing is controlled by means of a screwdriver�
Check that sufficient lubrication is obtained by putting your hand
in front of the exhaust port while adjusting the regulating valve�
If the hand is covered by a thin film of oil after a few seconds, the
lubricator has been correctly adjusted�
The amount of oil going into the rock drill increases when turning
the valve counter clockwise, and it decreases when turning the
valve clockwise� Oil consumption is 2�5–6 ml/minute�
Note!Tighten the nut after regulation�
Note!To much oil will have negative effects on the operation
whilst to little will result in damage to parts as the temperature
rises during operation�
Operation
Involuntary start�
WARNING
Involuntary start of the machine may cause injury�
• Keep your hands away from the start and stop device until you
are ready to start the machine�
• Learn how the machine is switched off in the event of an emer-
gency�
• Stop the machine immediately in all cases of power supply
interruption�
Drilling
Starting the rock drill
1� Open the main valve for compressed air�
2� Open the cock for the flushing water�
3� Adjust the feed control lever to give a suitable feed force for
collaring the hole�
4� Align the rock drill so that the working tool touches the desired
collaring point�
5� Move the throttle lever forward a little, which will start water
flushing, percussion and rotation�
6� Collar the hole with reduced feed force�
7� Move the throttle lever fully forward once the working tool has
gained a secure footing in the rock�
Adjust the feed force by means of the control lever so that the 8�
maximum penetration rate is obtained�
The start-and-stop device of Pusher Leg Rock Drill YT29A can
cause a risk of an unimtentional start�To reduce and avoid causing
the risk of unintentional start, the control valve og inlet hose must
be switched off while the rock drill is put aside for long time�
Note! Do not bend the working tool as this will increase wear of
the shank bushing and piston� Furthermore, it can also affect drill-
ing efficiency and increase the risk of working tool breakage�
Stopping the rock drill
Pull the throttle lever backwards, which will stop percussion, rota-
tion and flushing water�
Re-positioning the pusher leg
1� Switch off the rock-drill percussion and flushing by means of
the throttle lever�
2� Press the trigger, whereupon the piston rod is pulled back into
the pusher-leg cylinder automatically�
3� Re-position the pusher leg�
4� Release the trigger, whereupon the piston rod will move out-
wards again�
5� Move the throttle lever forward into the working position�
Note!The feed control lever does not need to be touched through-
out this operation�
Blow-cleaning the drill hole
Whipping air hose�
DANGER
A compressed air hose that comes loose can lasharound and
cause personal injury or death
• Check that the compressed air hose and the connections are not
damaged�
• Check that all compressed air connections are properly attached�
Move to the side and cover your eyes before starting to blow-
clean the drill hole� When blow-cleaning, particles and dirty
flushing water can emerge at speed from the drill hole��
CAUTION
• Always wear impact resistant eye protection with side protection
to avoid injury�
• Make sure that no co-workers are in range when blow-cleaning�
If powerful blow-cleaning of the drill hole is required, turn the
throttle lever fully backwards beyond the stop position for extra
blowing, whereupon the rock drill stops�This can be done during
drilling� When the drill hole is clean, turn the throttle lever for-
wards again to re-start the rock drill�
When you have finished drilling
Run the rock drill at medium speed when retracting the working
tool from the drilled hole�
Lay down the rock drill on a stone, wooden plank or similar ob-
ject, so as to prevent drill cuttings and other foreign matter from
entering the chuck�
Turn off the water pressure before the air pressure� Run the rock
drill for a few seconds to clean out water and moisture after the
water has been shut off�

12
Always switch off the main control valve on the air inlet hose to
prevent unintentional start of the rock drill�
Maintenance
Regular maintenance is a prerequisite for machine safety� Replace
damaged and worn components in good time� For a major service
to the machine, contact your nearest authorized workshop�
Check the machine and tools for wear and damage at regular
intervals� Do not use very worn or damaged tools�
When cleaning mechanical parts with a solvent, make sure that
you comply with current health and safety regulations and ensure
that there is sufficient ventilation�
Daily maintenance, regular checking of wearing parts and carrying
out repairs in good time prevents breakdowns and increases the
service life of the machine�
• Always oil the rock drill and pusher leg well, before you put
them into storage�
• Store in a clean and dry place�
• Make sure that no foreign matter enters the machine�
• Protect the chuck using a wooden plug or a clean piece of cotton
waste�
• Always hose down and wipe clean the rock drill and pusher leg
after use�
• In the case of long-term storage, pour a quantity of oil directly
into the rock-drill's air intake and then turn on the air briefly�This
will protect the machine from corrosion�
Once a shift (after 8 hours of operation)
• Check the wear in the chuck bushing� If the wear limit has been
exceeded, the working tool shank will wear more quickly, or
become deformed�This will lead to stoppages and increased
working tool consumption�
• Check the tightness of the side-bolt nuts�
•The tightening torque shall be 150 Nm�
• Check the rock drill's connection to the pusher leg�
• Check the hoses, couplings and controls for leakage and dam-
age�
• Check that the rock drill and pusher leg are receiving enough
lubrication� Fill the lubricator as necessary�
• Drain the water separator�
• Check the air and water pressure� Make sure that the water pres-
sure is at least 1 bar lower than the air pressure�
Once a week (after 40 hours of operation)
Carry out a basic check of all functions of the drilling equipment�
Once a month (after 200 hours of operation)
• Send the rock drill to a workshop for inspection� The local operat-
ing conditions will determine whether or not this is a suitable
interval for overhauling the drill�
• Dismantle and clean the lubricator�
• Clean out the water separator�
Differences between original parts and
pattern parts
When buying a part, the first thing to do is to verify that the part is
an Atlas Copco part� Most parts can be identified�
Every day
Before undertaking any maintenance or changing the insertion
tool on pneumatic machines, always switch off the air supply and
bleed the machine by depressing the start and stop device then
disconnect the air hose from the machine�
• Clean and inspect the machine and its functions each day before
the work commences�
• Conduct a general inspection for leaks and damage�
• Check that the air inlet nipple is tightened and that the claw
coupling is free from damage�
• Check the function of the throttle handle� Make sure that it
moves freely up and down�
• Check the function of the retainer� Make sure that it locks the drill
steel�
• Change damaged parts immediately�
• Replace worn components in good time�
• Check the through bolts of the machine� Make sure that they are
tightened�
• If the machine is equipped with a silencer, check for damage�
Checking for wear
1� Check the wear in the chuck
bushing using the Atlas Copco
gauge 90002668 (22 mm),
90002669 (25 mm)� If the wear
limit has been exceeded, the drill
steel shank will wear more quickly,
or become deformed�This will
lead to stoppages and increased
drill-steel consumption�
2� Check the tightness of the side-
bolt nuts (A)�Tighten to a torque
of 80 Nm�
3� Check the rock drill's connection
to the pusher leg�
4� Check the hoses, couplings and controls for leakage and dam-
age�
5� Check that the rock drill and pusher leg are receiving enough
lubrication� Fill the lubricator if necessary�
6� Check the air and water pressure� Make sure that the water
pressure is at least 1 bar lower than the air pressure�
Periodic maintenance
After each operating period of approximately 100 working hours
or three times a year the machine must be dismantled and all
parts be cleaned and checked�This work must be performed by
authorized staff, trained for this task�
Selection of spare parts
This machine is a heavy-duty rock drill; there are strict require-
ments on selecting spare parts� Use only genuine parts for
replacement, to ensure stable performance� Do not use pattern
parts, which not only have a short working life but also cause con-
sequential damage to other parts, due to differing measurements
and methods of manufacturing�
Damage patterns
Worn or broken parts must always be studied carefully before
they are replaced�They can give important information about the
condition of the drill and about the way it is used and maintained�

13
Problem Cause
Steel parts are a bluish colour The parts have been
subjected to excessive
heat� This can be caused by
insufficient lubrication or
idling
Steel parts have small almost
microscopic fissures on the
wear surfaces
See above
Irregular cavities on the
surface See above of bronze
parts
See above
Cutting marks Secondary damage
Dirt inside the drill
Interior misalignment due to
uneven tension of the side
bolts
Measures to prevent freezing
In low ambient temperatures, ice can form in the machine�This
can be avoided if the water in the compressed air is removed�This
can be done by equipping the air lines with water separators and
drainage points for water condensate�
If the rock drill ices up, it must not be heated to melt the ice� Let
the ice thaw at room temperature�
Note! Do not pour methylated spirits or similar substances into
the rock drill, as they will interfere with the lubrication and lead to
increased wear�
Scrapping and waste disposal
Used and worn-out machines must be disposed of in such a way
that as much of the material as possible can be recycled and the
impact on the environment is kept to a minimum�
