Safety instructions
To reduce the risk of serious injury or death to yourself or others,
carefully read through this instruction booklet before putting
the rock drill to use. Always follow the instructions given in this
manual.
• Always wear a safety helmet, impact resistant eye protection
with side protection and ear protectors during drilling. Any local
regulations that exist must also be observed.
• When drilling in certain minerals, there is a risk of spark genera-
tion. Before starting work, check that the machine is approved (in
accordance with local regulations) for work under such condi-
tions.
• Always take great care when using the machine.The drill steel is
subjected to heavy loading and can break, with a risk of injury to
personnel.
• Check that the hoses used are of the right quality, and that all
hose connections are in good condition and properly tightened.
• Before starting work on any of the systems, make sure that the
air and water systems are un-pressurized.
• Make sure that there are no concealed wires or other sources of
electricity. Never drill near any electric wires or other sources of
electricity.
• Exposure to crystalline silica (sometimes called 'silica dust') as
a result of drilling in rock may cause silicosis, cancer or death.
Never operate the rock drill without water flushing.
A compressed air hose that comes loose can lash around and
cause personal injury or death. Check that the compressed air
connections are not damaged and that they are properly attached.

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 continuous
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.
A compressed air hose that comes loose can lash around
and cause personal injury or death. Check that the com-
pressed air connections are not damaged and that they are
properly attached.
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� Check the lubrication oil level
• Fill the lubricator with oil if necessary.
• Always use a recommended lubricant.
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
Set the water preassure to around 3 bar. Maximum water pres-
sure is 1 bar less than the working pressure. For example if the air
pressure is 5 bar, then the water pressure must be below 4 bar to
prevent water entering the impact mechanism.
Air hose dimensions
The air hose diameter must be no less than 25 mm.The inner
diameter of connection nipples and hoses must be no less than 19
mm.The ideal overall air hose length is less than 15m.
Water hose dimensions
The water hose inner diameter must be no less than ½".
5� 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.
Do not pour methylated spirits or similar substances into the
rock drill, as they will interfere with the lubrication and lead to
increased wear.
Fitting and removing the drill steel
Before fitting the drill steel
• Check that the drill steel shank is of the correct size and length
for the chuck used.
•The shank must be clean and the drill steel must be in good
condition.
•The suitable quenching hardness of the shank is HRC48-53. A
harder end face will cause piston damage 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 drill steel.
•The shank end face shall be flat and perpendicular to the axis.
• Remove sharp edges from the shank's end face. A rough shank
surface will 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.
Fitting the drill steel
1� Push the retainer outwards in the direction of the arrow (see
picture below), until the front portion of the retainer is able to
accommodate the drill steel collar.
2� Insert the drill in the chuck.
3� When the drill bottoms, push back the retainer to lock it.

5
Removing the drill steel
1� Push the retainer outwards in the direction of the arrow until
the drill steel collar disengages from the front of the retainer.
2� Pull the drill steel 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� Pushing the lever in this direction will increase feed force.
B� Pulling the lever in this direction will decrease feed force
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 the pusher leg, or when there is a tendency to jam. When the
trigger is released, the feed control setting is activated again.
Oil regulating valve
Oil dosing is controlled using a screwdriver.Tighten the nut after
regulation.
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.Too much oil will have neg-
ative effects on the operation whilst too little will result in damage
to parts as the temperature rises during operation.
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.
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 drill steel touches the desired
collaring point.

6
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 drill steel has
gained a secure footing in the rock.
8� Adjust the feed force using the control lever so that the maxi-
mum penetration rate is obtained.
Note! Do not bend the drill steel as this will increase wear of the
shank bushing and piston. It can also affect drilling efficiency and
increase the risk of drill steel breakage.
Stopping the rock drill
Pull the throttle lever backwards, which will stop percussion, rota-
tion and flushing water.
Checking the lubrication
The chuck and drill steel shank must always be covered by a film
of oil.
Re-positioning the pusher leg
1� Switch off the rock-drill percussion and flushing using 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
When blow-cleaning, particles and dirty flushing water can
emerge at speed from the drill hole.
• Move to the side and cover your eyes before starting to blow-
clean the drill hole.
• Always wear impact resistant eye protection with side protec-
tion to avoid injury.
• Make sure that no co-workers are in range when blow-cleaning.
CAUTION
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 drill steel
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.
Maintenance
Regular maintenance is a prerequisite for machine safety. Replace
damaged and worn components in good time.
Check the machine and drill steel for wear and damage at regular
intervals. Do not use a very worn or damaged drill steel.
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.
• Make sure that no foreign matter enters the machine.
• Always hose down and wipe clean the rock drill and pusher leg
after use.
Once a shift (after 8 hours of operation)
• Check the wear in the chuck bushing. 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.
• Check the tightness of the side bolt nuts.
• 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.
• Every day before using the drill, blow out the air hose to clear it
from accumulated dirt and moisture.
• 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 oper-
ating 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.
Selection of spare parts
Use only genuine parts for replacement, to ensure stable per-
formance. Do not use pattern parts, which not only have a short
working life but also cause consequential damage to other parts,
due to differing measurements and methods of manufacturing.
Storage
• Always oil the rock drill and pusher leg well before you put them
into storage.
• Store the rock drill and pusher leg in a clean and dry place.
• 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.
• Protect the chuck using a wooden plug or a clean piece of cotton
waste.
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.

pawls have difficulty catching
Chuck nut worn out Replace the chuck nut if the splines have been worn to 1/2 of
the spline width
Pawls worn Replace all pawls, all pawl springs and all pawl pins
Uneven running Piston has seized in the guide sleeve or the piston
guide
Replace the guide sleeve/piston guide. If required, polish
the piston. Check the piston for heat damage such as blue
colouring and/or fissures. If it is damaged in this way,
replace the piston as well
Dirty or damaged main valve. Caused by impurities
or foreign matter entering the drill with the
compressed air
Clean and polish the valve so that it seals against the
corresponding cylindrical and plane sealing surfaces. If this
is not possible because the defects are too serious, the valve
must be replaced
Freezing. Caused by leakage in the flushing system
or by excess water in the compressed air or by
excessive water pressure
Check the flushing tubes and seals and the water pressure.
Drain water from the compressed air system. If the problem
continues,
fit a water separator in the airline system.
Uneven running
(continued)
The side bolts are unevenly or insufficiently
tightened. Can cause the various parts to lose their
alignment, resulting in the seizure of the movable
parts. Abnormal strains on the side bolt may result
in fracture at the threads.
Check and repair any damage to the contact points and
tighten the bolts with the correct tightening torque
The drill gets hot Lack of oil Add oil and check that it runs through. It is not sufficient
that there is oil in the exhaust air. There must also be an oil
coating on the shank of the drill steel.
Freezing High level of humidity in the compressed air Use water traps
Water pressure higher than the air pressure Lower the water pressure
Water pipe
breakage
Misalignment of the shank Change drill steel or shank sleeve or both
Damaged flushing hole in the shank Change drill steel
Chipping of the
piston tip
Misalignment of the shank Change the drill steel or shank sleeve or both
Excessive wear of the piston tip Change piston
Spline breakage
Lack of lubrication Lower the water pressure if it is the same as or greater than
the air pressure
Increase lubrication or change oil
Dirt intrusion (specially when drilling upwards) Increase service intervals
Piston breakage Lack of lubrication Lower the water pressure if it is the same as or greater than
the air pressure
Increase lubrication or change oil
Uneven tension in the side bolts Tighten the bolts correctly
Worn guide sleeve/piston guide (can be confirmed
by the cushion test)
Change the worn part
Side bolt breakage Uneven tension on the bolts Tighten the bolts correctly
