1/2” pneumatic reversible hammer Article: 1561
Code: 615322
Pneumatic reversible hammer 1561 apply
to PREN 792 -6.
Vibration level per ISO 8662-7
Noise level according to ISO 3746:1995 (E)
Maximum air pressure: 6.2 BAR (90 PSI)
OPERATING INSTRUCTION
1. Warning
1.1 Air pressure :
The air pressure must be restricted at or less than the maximum pressure of 90
psi (6.2 bar), do not exceed it.
1.2 Air line :
Use an air hose between the compressor and the tool. The corresponding hose
internal diameter is recommended in the attached table in the data sheet.
Compressed air is cooled and its water content separated as soon as the air
leaves the compressor. However some of the water is condensed in the piping,
and can enter the tool mechanism and cause damage. An air filter and on oiler
should be installed between the compressor and the tool. Use a recommended
compressor in the date sheet or larger for each tool.
WARNING :
* always read the instruction before using power tools
* always wear safety googles
* wear hearing protection
* Avoid prologned exposure to vibration

1.3 Air hose
Clean the hose with a blast of compressed air
before connecting the hose to air tool. This
will prevent both moisture and dust within
the hose from entering the tool and causing
possible rust or malfunction. To compensate
for unusually long hose ( over 25ft ) the line
pressure should be increased accordingly.
1.4 Sockets :
The tool is used fastening or loosing of
threaded fasteners. The sockets must be of the
impact type with suitable square drive dimen-
sion. Do not use any other type of socket.
1.5 Approved eye protection, mask, hearing
protection and gloves shall be worn when
operate this tools.
1.6 The working place shall be ventilated.
1.7 Release the on-off device in case of air
supply failure.
1.8 Ensure that the power tool is firmly at-
tached when using a suspension device.
1.9 Release the start and stop switch in case
of a failure of energy supply.
1.10 Use only a lubricant recommended by the
manufacturer.
2. Operation method
2.1 On-off switch
The on-off switch is on the inside or
outside of the grip. It is a “ hold-to-
run” type. This tool stops rotation
in a few seconds after releasing the
lever. For the sake of safety, please
ensure it has completely stopped
before touching.
2.2 Torque adjuster :
You can adjust the torque by
rotation the knob. Torque is
indicated by numbers. Lower
number indicates lower output
torque setting and vise versa.
2.3 Rotating direction :
Ensure the direction of rotation
is correct before operation. The
“F” indicates forward and the “R”
indicate reverse. Forward is defined
as clockwise viewed from the
operators position.
3. Maintenance
3.1 Lubrication :
Before connecting the hose, apply 4 to 5 drops of # 60 spindle oil
at the inlet. Use of a thicker oil can lead to reduced performance of
malfunction. Also oil after every 3 to 4 hours of operation.
3.2 Storage :
Avoid storing the tool in a location subject to high humidity. If the tool
is left as it is used, the residual moisture inside the tool can cause rust.
Before storing and after operation, oil the tool at the air inlet with
spindle oil and run it for a short time.
3.3 Ordering service part .
For further operational and handling information or for replacement of
parts and components contact the outlet from where you purchased the
tool or the service division of your company.

WARNING
1. The too should not be used in potentially explosive
atmospheres
2. Disconnect the air hose before changing or
adjusting any sockets.
3. Before using the tool, please ensure that all
connections are secure. Loose air hoses may become
disconnected and may be caught in the revolving
spindle.
4. Prevent loose clothes, long hair etc. from coming
into contact with the revolving spindle, as this could
cause injury.
5. Excessive high air pressure that exceeds the
recommended maximum pressure may cause injuries
to the user.
6. Keep your body in well balanced position and
always wear gloves to reduce the risk of becoming
trapped due to torque between handle and work
piece.
7. Prolonged exposure to vibration can cause injury.
8. Ensure that you are aware of the direction of
rotation before starting the tool. Failure to do so may
cause injury.
9. Slip/trip/fall is a major reason of serious injury.
Beware of excess hose left on the workplace floor.
10. Wearing eye/ face protector reduce the danger
to the operator from flying objects caused by socket
failure or other reasons.
11. Wearing correct breathing protection could avoid
inhaling dust or debris from work process that can be
harmful to your health.
12. Never operate the tool away from the workplace.
It may cause the accessories to be detached from the
tool and cause injury to someone in the vicinity.
13. High sound level can cause permanent hearing
loss. Use hearing protection while operating the tool.
14. The ratchet wrench may kickback and cause
injury if the rut is too tight In this situation
use manual operation to loosen the nut before
continuing to use the power tool.
15. Unexpected tool movement due to reaction
forces or breakage of sockets or reaction bar may
cause injuries.
16. There is a risk of being injured specially when
working in confined areas if hands are not kept
away from the reaction bar. Keep hands away from
the socket.
17. In case of socket failure, there may be danger to
people from fragments being flying from the impact
wrench.
18. Be aware of whipping compressed air hose.
19. The power tool is not insulated and must be kept
away from electric power source.
