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

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)

Installation
Installation of vibrating tools
It is recommended that a minimum length of 300 mm of flexible hose for com-
pressed air is inserted between a vibrating tool and the quick-action coupling.
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 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)
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.
•Note – 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
Fitting the chisel
Insert the chisel so that chisel retainer (33) snaps into the chisel groove.Check
that the chisel retainer spring is tensioned.
Removing the chisel
Lift the rear end of the chisel retainer (33) and pull the chisel out.
Using the hand guard
The hand guard (41) supplied as an accessory for vibrationdamping has a snap
lock for attachment to the front housing (30).
If it is necessary to guide long chisels near the chisel blade, detach the collet
from the machine with a light jerk and move it down over the chisel.
Attach the collet to the machine before changing chisels.
Avoid holding the chisel directly.
Vibration damping
Vibration damping is accomplished by means of two air springs, one in the im-
pact mechanism between the piston (23) and thecylinder (22) and one behind
the chisel collet ring (28). This latter spring dampens the shock wave reflex
from the chisel. The necessary feed force is determined by the air pressure to
the machine. When the throttle valve is pressed only part of the way in, a lower
speed force is thus required.
For complete vibration damping between the machine housing (2) and the im-
pact mechanism: Use sufficient feed force so that the chisel collet ring (28) is
pressed up a few millimeters from the buffer (29), i.e. the chisel is pressed in a
corresponing amount into the front housing.
If the feed force is too high, the chisel collet ring (28) will butt against the
cylinder (22), whereupon vibrations increase noticeably and the impact effect is
reduced.
Idling
When idling, the machine output is appreciably reduced in that automatic vent-
ing occurs via the collet (25). The idling strokes are absorbed by an elastic buf-
fer (29). When switching from work to idling, a few individual hard idling
strokes may be absorbed via the buffer.
Avoid unnecessary idling
When the buffer (29) is worn, the chipping hammer may stop while operating
and/or be difficult to start. If this occurs, replace the buffer immediately in or-
der to prevent harmful blows directly on the front housing (31).
Maintenance
Overhaul
If the chipping hammer is in daily use, it should be cleaned and overhauled
once every sixth month.
Removal of front housing with chisel retainer and buffer:

RRD37/57 EN Safety and operating instructions

1. Disconnect the machine from the compressed air mains.
2. Back off the screw (32) using key (52).
3. Screw the threaded end of key (52) into the hole “A” so that the front hous-
ing (31) is pried apart and can be removed from the machine casing (2).
4. Remove the buffer (29) with the aid of a screwdriver.
5. Fit a new buffer, making sure that the locking edge snaps into the groove in
the front housing.
6. Before fitting the front housing, check that the chisel collet ring (28) is fitted
with the cone facing towards the sealing ring (27).
7. Push the front housing onto the machine housing as far as it will go.
8. Back off and remove the key (52). Fit the screw (32) andn tighten with a
torque of 40 Nm (4 kpm).
Lubrication
During work, oil must be supplied to the chipping hammer once per shift in an
amount of 2.5 ml. The oil is dripped into the air hose. When the machine is in
continuous service, installation of an Atlas Copco oil—fog lubricator in the
compressed air line is recommended.
Always use lubricants of good quality. The oils and greases mentioned in the
chart are examples of lubricants which are recommended.

Ergonomic guidelines
Consider your workstation as you read through this list of general ergonomic
guidelines and see if you can identify areas for improvement in posture, compo-
nent placement, or work environment.
• Take frequent breaks and change work positions frequently.
• Adapt the workstation area to your needs and the work task.
• Adjust for convenient reach range by determining where parts or tools
should be located to avoid static load.

Safety and operating instructions EN RRD37/57
10 © Atlas Copco Industrial Technique AB - 9836 977800 00
• Use workstation equipment such as tables and chairs appropriate for the
work task.
• Avoid work positions above shoulder level or with static holding during as-
sembly operations.
• When working above shoulder level, reduce the load on the static mus-
cles by reducing the weight of the tool, using for example torque arms,
hose reels or weight balancers. You can also reduce the load on the static
muscles by holding the tool close to the body.
• Make sure to take frequent breaks.
• Avoid extreme arm or wrist postures, particularly for operations requir-
ing a degree of force.
• Adjust for convenient field of vision by minimizing movement of the eyes
and head during the work task.
• Use the appropriate lighting for the work task.
• Select the appropriate tool for the work task.
• Use ear protection equipment in noisy environments.
• Use high-quality inserted tools or consumables to minimize exposure to ex-
cessive levels of vibration.
• Minimize exposure to reaction forces.
• When cutting:
A cut-off wheel can get stuck if the wheel is either bent or if it is not
guided properly. Make sure to use the correct flanges for cut-off wheels
and avoid bending the wheel during cut-off operation.
• When drilling:
The drill might stall when the drill bit breaks through. Makes sure you
use support handles if the stall torque is too high. The safety standard
ISO11148 part 3 recommends using something to absorb the reaction
torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.
• When using direct-driven screw or nutrunners:
Reaction forces depend on tool setting and joint characteristics. The abil-
ity to bear reaction forces depends on the operator’s strength and pos-
ture. Adapt the torque setting to the operator's strength and posture and
use a torque arm or reaction bar if the torque is too high.
• Use dust extraction system or mouth protection mask in dusty environments.
