2.14 Unexpected tool movement or breakage of inserted tool may cause injuries.
2.15 Unsuitable postures may not allow counteracting of normal or unexpected
movement of the drilling and breaking hammer. A working position shall be
adopted which remains stable in the event of a break of the inserted tool.
2.16 It is recommended to use dust collection devices or water flushing where
ever appropriate.
2.17 Drilling and breaking shall be isolated from the energy source before
changing an inserted tool.
2.18 Reaction torque may occur.
2.19 If the application for which the hammer is being used may result in the
reaction torque upon the operator, a second handle shall be used. The risk of
drawing in or trapping due to the rotating inserted tool should be taken care.
2.20 The risk of fire when spillage of fuel occurs should be prevented.
2.21 No smoking when filling with fuel.
2.22 Avoiding contact of fuel and oil with the skin.
2.23 Do not use in an unventilated environment, in closed pits, where the

2.27 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.
2.28 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.
2.29 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.
2.30 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.
2.31 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.
