Important information for safer use of percussive tools
This manual follows the EC Machines Directive (2006/42/EC) regarding opera-
tor's instructions and relevant parts of standards from CEN TC 255 "Hand-held
power driven non-electric tools - Safety" These instructions concern operation,
handling of machine, inserted tool and equipments as well as maintenance.
Neglect to follow these long established recommendations may cause serious
hazards.
Make sure that the operator has fully understood the following recommenda-
tions and has full access to them.
pay strict attention to following measures the operator has to take in order to
avoid risks of misuse or accident
Installation
Follow the instructions for air preparation given in the written instructions sup-
plied with the machine.
When lubrication is recommended - use recommended lubricants only.
Check hose size and air pressure.
Avoid the risk of whipping hose - regularly check hose, hose fittings and condi-
tion of clamps.
Check that the exhaust air is directed to avoid blowing dust or air from the work
piece onto the operator or other persons. Arrange for barriers if possible.
When necessary, use exhaust hose and arrange for dust collection.
Avoid accidents when using the machine
1 The chisel, die or punch may fall out or may be shot out of the
tool accidentally causing serious injury
To prevent injury from a flying chisel:
• always use a retainer
• inspect the retainer for wear or damage regularly
Safety and operating instructions EN RRF 21

and:
• be aware that the chisel may break during operation due to fatigue
• never trigger the machine unless held against a work piece
• remove chisel, die or punch from machine when work is over
• before changing accessories, chisel or die - disconnect the machine from the
air supply
• release the start and stop device in case of interruption of energy supply
• when finishing a job, disconnect the machine from its air supply
2 Chips and sparks shall be prevented from striking an eye or
another worker
To prevent vision loss:
• always wear eye protection
• isolate work of this kind by using barriers between work stations
• do not use the machine for other purposes than it is intended for
3 Prevent body injury by using:
• gloves
• protective shoes
• helmet
• always wear eye protection
4 Explosive atmosphere must not be ignited
To prevent injury and property loss from fires:
• use other technique
• use accessories of non sparking material (e.g. needle attachment of Beryl-
lium copper for a needle scaler)
5 Electric chock may be fatal
• avoid chiselling into electric wiring hidden inside walls etc.

Long term risks when using the machine
6 Always use ear protection
To prevent gradual loss of hearing due to exposure to high noise levels:
• wear ear protection
7 Vibration may be harmful to hands and arms
• use vibration dampened tools if available
• reduce the total time of exposure to vibrations, particularly if the operator
has to guide the chisel by hand
8 Dust generated during operation may be harmful
• use spot suction or a breathing apparatus
Proper use and maintenance
9 Do not perform idle blows with a hammer
• they will cause high internal stresses and shorten the life of the tool
• note the risk of shooting out the chisel, die or punch if the retainer is not in
order
10 Quick coupling
• if a quick coupling is used on a percussive tool, it shall be separated from
the tool by a whip hose (length 0.5 m)
11 Maintenance
Good service life and safe function is offered if the instructions for lubrication,
maintenance and overhaul supplied with the machine are followed.
Use genuine Atlas Copco replacement kits and parts only.

Warning
Make sure you are familiar with the operating instructions before you use this
machine.
This machine, its attachments and accessories must only be used for the pur-
pose for which they were designed:
General chipping and scaling work, fettling of castings in foundries, hole mak-
ing and light demolition in construction and building industry (not for nailing
without proper attachments).
For product liability and safety reasons any modification to the machine, its at-
tachments or accessories must be agreed in advance with an authorized techni-
cal representative of the manufacturer.
This machine does not satisfy the normal requirements for use in explosive
environment as the machine casing contains aluminium.
To run the tool with no or too low feed force increases the load of the retainer
and will shorten service life.

• Install chisel (j) and chisel retainer (i), see figure.
• Before use – Put a few drops of air tool oil through the air inlet.
• Connect the machine to the air line according to figure. If a quick coupling
is used, it should be separated from the machine by a whip hose (length 0.5
m).
• The compressed air should be free from water and dirt as far as possible.
The installation of an Atlas Copco filter/regulator/lubricator air preparation
set is recommended to ensure a high quality air supply to the machine. For
lubrication, only use high quality air tool oils.
Air quality
• For optimum performance and maximum machine life we recommend the
use of compressed air with a maximum dew point of +10°C. We also rec-
ommend the installation of an Atlas Copco refrigeration-type air dryer.
• Use a separate air filter of type Atlas Copco FIL. This filter removes solid
particles larger than 15 microns and also removes more than 90 % of liquid
water. The filter must be installed as close as possible to the machine/equip-
ment and prior to any other air preparation unit such as REG or DIM (please
see Air Line Accessories in our main catalogue). Blow out the hose before
connecting.
Models which need air lubrication:
• The compressed air must contain a small quantity of oil.
We strongly recommend that you install an Atlas Copco oil-fog lubricator
(DIM). This should be set according to air consumption by the air line tool
according to the following formula:
L = Air consumption (litre/s).
(May be found in our sales literature).
D = Number of drops per min (1 drop = 15 mm3)
L* 0.2 = D
this applies to the use of long work cycle air line tools. A single point lubri-
cator type Atlas Copco Dosol can also be used for tools with short running
cycles.
Information about Dosol settings may be found under Air Line Accessories
in our main catalogue.

Lubrication-free models:
• In the case of lubrication-free tools it is up to the customer to decide on the
peripheral equipment to be used. However, it is no disadvantage if the com-
pressed air contains a small quantity of oil e.g. supplied from a fog lubrica-
tor (DIM) or Dosol system. This does not apply to turbine tools, which
should be kept oil free.
Compressed air connection
• The machine is designed for a working pressure of 6–7 bar = 600–700 kPa =
87–102 psi.
• Blow out the hose before connecting.
Installation proposal
Choosing the correct couplings, hose and clamps can be a troublesome digging
into details. To save your time and to ensure correct capacity of the airline in-
stallation, from the tapping point to the tool, we offer you an installation pro-
posal.

Handling
Operation
Feed force
To get full power out of the tool a feed force must be applied to bring the mech-
anism into the middle of its free travel in the handle.
Too high feed force results in reduced vibration damping, without increasing
the material removal, as the cylinder will hit the bottom in the handle.
The standard recoil spring (33) is designed for best vibration damping and con-
trol of the chipping process in most applications, see fig.
The enclosed alternative recoil spring (33a), with yellow paint marking, is
softer than the standard spring. If the tool is going to be used in a light applica-
tion where standard spring may be too hard, please mount the alternative spring
according to the enclosed instruction. Test the tool in your application and
chose the spring that works best.
Power control (Optional Accessory)

The percussive power of the machine can if necessary be reduced limiting the
throttle valve stroke, see figure:
Pull the setting knob (d) and turn it clockwise to reduce the power. Find a suit-
able position and lock the knob in one of its 10 holes.
At maximum power setting the throttle lever can be pushed fully to stop
into the handle.
Maintenance
Maintenance
Lubricate the machine regularly with air tool oil.
Before longer standstills clean and lubricate the machine. When putting the ma-
chine into operation again, flush through with paraffin or a similar fluid. Imme-
diately after flushing thoroughly oil the machine with air tool oil.
The machine should be dismantled for overhauling and cleaning at regular in-
tervals after 500 running hours but at least once every six months.
The use of other than genuine Atlas Copco replacement parts may result in de-
creased tool performance and increased maintenance and may, at the option of
the company, invalidate all warranties.
Cleaning
At 100 hour operating intervals or earlier if operation becomes sluggish or the
machine shows sign of sticking, flush through with paraffin or a similar mate-
rial. Immediately after flushing thoroughly oil the machine with air tool oil.
The strainer inside the inlet adapter (b) should be cleaned frequently to prevent
choking with resultant decrease in capacity.
Dismantling
All threads are right hand.
• Remove ring (35).
• Clamp the cylinder (20) firmly in a vice and unscrew the handle (1).
• Remove pin (29) – if necessary by drilling (protect exhaust holes and thread
from chips by sticky tape) – and back off the outer cover (27).
• Remove, clean and inspect all parts – see spare parts list illustration.
Assembly
• Replace all O-rings and worn parts.
• Ensure all parts are clean and have a film of air tool oil lubrication.
• Clamp the cylinder (20) vertically in a vice.
• Mark the position of the five deep drillings for air distribution in the cylin-
der (totally 12 holes) with a marking pen.
Insert piston (24) and parts (25,26).
Tighten the outer cover (27), recommended tightening torque 50 Nm.
Protect exhaust holes and the thread by sticky tape to avoid contamination
with drill chips.
Drill a new hole, dia 3.9–4 mm x 8.8 mm, not interfering with the markings
