Safety regulations

Before starting, read these instructions carefully.
Important safety information is given at various points in these
instructions.
Special attention must be paid to the safety information contained
in frames and accompanied by a warning symbol (triangle) and a signal
word, as shown below.
Indicates immediate hazards which WILL result in serious or fatal injury if
the warning is not observed.
Indicates hazards or hazardous procedures which COULD result in serious
or fatal injury if the warning is not observed.
Indicates hazards or hazardous procedures which COULD result in injury or
damage to equipment if the warning is not observed.
Read through the operator's instructions for both the drill rig and
the DTH hammer thoroughly before putting the DTH hammer into serv-
ice. Always follow the advice given in the instructions.
Use only authorized parts. Any damage or malfunction caused by
the use of unauthorized parts is not covered by Warranty or Product
Liability.
The following general safety rules must also be observed:
Make sure that all warning signs on the rig remain in place and are
free from dirt and easily legible.
Make sure there are no personnel inside the working area of the
drill rig during drilling, or when moving the rig.
Always wear a helmet, goggles and ear protectors during drilling.
Also observe any local regulations.
The exhaust air from air driven hammers and grinding machines
contains oil. It can be dangerous to inhale oil mist. Adjust the lubricator
so that the correct rate of lubrication is obtained.
Make sure that the place of work is well ventilated.
Always check that hoses, hose nipples and hose clamps are prop-
erly tightened and secured, and that they are not damaged. Hoses that
come loose can cause serious injury.
Local regulations concerning air hoses and connections must
always be strictly observed. This is especially the case if the DTH-
hammer is to be operated at pressures above 10 bar (145 psi).
The machine must not be used for purposes other than those
prescribed by Secoroc. See "Application" on page 4.
