* are at least 18 years of age,
* are physically and mentally fit for this job
* have been instructed in operating drilling and breaking hammers and proven their ability for the job
to the employer
* may be expected to carry out the job they are charged with carefully.
The persons must be assigned the job of operating drilling and breaking hammers by the employer.
2. Drilling and breaking hammers are to be applied for their proper use. Both the manufacturer’s operator’s
manual and these safety instructions have to be observed.
3. The persons charged with the operation of these hammers have to be made familiar with the necessary
safety measures relating to the machine. In case of extraordinary uses, the employer shall give the
necessary additional instructions.
4. It is possible that these drilling and breaking hammers exceed the admissible sound level of 89 dB (A).
Operators must wear personal hearing protection if the admissible assessment sound level equals or
exceeds 89 dB (A).
Operation
1. The function of operation levers or elements is not to be influenced or rendered ineffective.
2. Make sure that the machine is connected only to voltage and frequency as indicated on its name plate.
Choose correct cross section for extension cord. See method of calculation instructions with diagram in
this manual.
3. The operator has to switch off drilling and breaking hammers, to disconnect them from the electric mains
and to store them in such a manner that they do not turn over be fore leaving the machines or going on
breaks.
4. Wear safety goggles in order to avoid injuries to the eyes.
5. We recommend wearing suitable working gloves.
6. Wear safety shoes while working with drilling and breaking hammers.
7. Drilling and breaking hammers are always to be operated with both hands on the handles provided for
this purpose.
8. When working with drilling and breaking hammers, especially when carrying out drilling jobs, the operator has to have a firm stand, particularly when working on scaffolding and ladders.
9. Drilling and breaking hammers are to be guided such that hand injuries caused by solid objects are
avoided. When carrying out demolition jobs at elevated places, special care is required to prevent the
machine or the operator from falling.
10. Avoid body contact with earthed components. When breaking connecting passages, make sure that
there are no electric wires or gas pipes. No one may stay in the room to which the passage is broken
through, as there is danger of injuries because of falling stones or tools.
11. During operation the tool holder must be closed. Tools and tool holder must be checked for wear in order
to guarantee proper functioning of holder.
12. The operation of this machine may cause broken - off pieces to be flung away. Therefore, during operation, no one except the operator is to come near this machine.
13. Drilling and breaking hammers have to be disconnected from the electric mains before changing tools.
14. The tools always have to be in perfect conditions.
15. Do not operate these machine in areas where explosions may occur.

SAFETY INSTRUCTIONS
16. Do not misuse the electric cable to pull or lift up the unit or to pull the plug out of the socket. Protect cable
from heat, oil and sharp edges.
17. Electric equipment and material may only be used if they comply with the operational and local safety
requirements. They must be in proper condition and this condition is to be maintained.
18. Do not expose electric tools to rain. Do not use electric tools in damp or wet surroundings.
Safety checks
1. Drilling and breaking hammers may only be operated with all safety devices installed.
2. Before starting operation, the operator has to check that all control and safety devices function properly.
3. Before starting operation, the overload clutch of drilling hammers has to be checked for proper functioning.
4. Regularly check cable for damage.
5. In case of defects of the safety devices or other defects reducing the operational safety of the drilling and
breaking hammers, the supervisor has to be informed immediately.
6. In case of defects jeopardizing the operational safety of the hammers, the machine has to be
switched immediately.
Maintenance
1. Only use original spare parts. Modifications to this machine, including the adjustment of the maximum
engine speed set by the manufacturer, are subject to the express approval of Wacker. In case of nonobservance all liabilities shall be refused.
2. Disconnect the drilling and breaking hammer from the electric mains before carrying out maintenance
and repair jobs.
3. Work on the electric parts of the machines may only be carried out by skilled technicians.
4. The green and yellow ground wire of the connecting cable of machines without protective insulation has
to be longer than the other wires so that it is no ripped out first in case the strain relief fails. A break in
this wire would entail grave danger. Check ground wire for passage after repairs.
5. As soon as maintenance and repair jobs have been completed, all safety devices have to be reinstalled
properly.
Transport
When being transported on vehicles, precautions have to be taken that these hammers do not slip or turn over.
Maintenance checks
According to the conditions and frequency of use, drilling and breaking hammers have to be checked for safe
operation at least once every 6 months by skilled technicians, such as those found at Wacker-service depots
and have to be repaired if necessary.
Please also observe the corresponding rules and regulations valid in your country.
