5.2 Take the necessary precautions to make the
workplace safe
●
Ensure that the workplace is well lit.
●
Ensure that the workplace is well ventilated.
●
Keep the working area tidy. Objects which could cause
injury should be removed from the working area.
●
When working, keep other persons, particularly chil-
dren, outside the range of the tool.
●
Avoid unfavorable body positions.
●
Wear eye protection. Wear breathing protection when
the work creates dust.
●
Wear non-slip shoes and always work from a secure
stance.
●
Wear protective gloves.
●
Do not wear loose clothing, loose long hair or jewelry
as these can become caught up in moving parts.
●
To avoid tripping and falling when working, always lead
the supply cord, extension cord and extraction hose
away to the rear.
●
Concealed electric cables or gas and water pipes pre-
sent a serious hazard if damaged while you are work-
ing. Accordingly, check the area in which you are work-
ing beforehand (e.g. using a metal detector). Avoid
contact between your body and earthed / grounded
objects, such as pipes or radiators. External metal parts
of the tool may become live, for example, when an elec-
tric cable is drilled into inadvertently.
●
Use a vice or clamp to secure loose workpieces.
5.3 General safety precautions
●
Operate the tool only as directed and only when it is
in faultless condition.
●
Take the surrounding conditions into account. Do not
expose the tool to rain or snow and do not use it in
damp or wet areas. Do not use the tool where there
is a risk of fire or explosion.
●
Never leave the tool unsupervised.
●
The side handle must always be fitted when the tool is
in use.
●
The tool is for hand-held use only.
●
Hold the side-handle securely at the end furthest from
the tool.
●
Keep the tool, especially its grip surfaces, clean and
free from oil and grease.
●
When not in use, the tool must be stored in a dry place,
locked up or out of reach of children.
●
Disconnect the supply cord plug from the socket when
the tool is not in use (e.g. during breaks, before main-
tenance and before changing insert tools).
●
Take care of your insert tools. You will be able to work
more efficiently and more safely if the insert tools are
kept sharp and clean. Observe instructions on care and
maintenance and on changing insert tools.
●
Do not overload the tool. It will work more efficiently
and more safely within its intended performance
range.
5.3.1 Mechanical
●
Observe the instructions concerning care and main-
tenance and replacement of insert tools in good time.
●
Ensure that the insert tools used are equipped with the
correct connection end system and that they are prop-
erly fitted and secured in the chuck.
5.3.2 Electrical
●
Check the condition of the tool including the supply
cord and extension cord as well as the plug connec-
tions. Do not operate the tool if damage is found, if the
tool is not complete or if its controls cannot be oper-
ated faultlessly.
●
Do not touch the supply cord in the event of it suffer-
ing damage while working. Disconnect the supply cord
plug from the socket.
●
Damaged switches must be replaced at a Hilti service
center. Do not use the tool if it cannot be switched on
and off correctly.
●
The tool should be repaired by a trained electrical spe-
cialist (Hilti service center).
●
Never carry the tool by the supply cord.
●
Grip the plug and not the supply cord when pulling it
out of the socket.
●
Do not expose the supply cord to heat, oil or sharp
edges.
●
When working outdoors, use only extension cords
approved and correspondingly marked as suitable for
outdoor use.
●
To avoid a risk of accident, use only original Hilti spare
parts.
●
Never operate the tool when it is dirty or wet. Dust or
dampness on the surface of the tool make it difficult
to hold and, under unfavorable conditions, may lead
to electric shocks.
5.3.3 Thermal
●
The insert tool may become hot during use. You should
therefore wear protective gloves when changing insert
tools.
