Safety precautions
When using electric tools, the following fundamental
safety precautions must always be observed in order to
avoid the risk of injury, electric shock and fire hazards.
Please read and observe the instructions below before
using the tool.
1. Use protective equipment.
2. Wear suitable working clothing.
Do not wear loose clothing, loose long hair or jewellery
as it can become caught up in moving parts of the machine.
Wear non-slip shoes.
3. Make the working area safe.
Objects which could cause injury should be removed
from the working area. Ensure that the area is well lit.
When working, keep other persons outside the range of
the tool you are using.
4. Take the influences of the surrounding area into
account.
Do not operate the tool in the vicinity of flammable liquids
or gasses.
Do not use the tool under water.
5.
Check the tool each time before use.
Check the condition of the tool. Do not use it if it is dam-
aged, incomplete or if the controls cannot be operated
correctly.
6. Use the correct insert tool.
Ensure that the insert tools (drill bits, etc.) are equipped
with the appropriate connection end for the chuck sys-
tem in use and that they are locked in position correctly
in the chuck.
Use only the recommended original Hilti accessories
and auxiliary equipment.
7. Use the tool only for the purposes for which it is
intended (see page 8).
Do not overload the tool.
8.
Apply a safe working method.
Avoid unfavourable body positions. Always ensure that
you have a safe stance. Always remain attentive. The
drill bit may become stuck unexpectedly. Switch the tool
off if you are distracted from your work.
9.
Take care to avoid concealed cables and pipes.
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 con-
tact 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 electric
cable is drilled into inadvertently.
10. Avoid unintentional starting.
The forwards / reverse / transport lock switch should be
brought into the transport lock position (middle posi-
tion
) when the tool is not in use, e.g. during pauses
between work, before maintenance, when changing
insert tools and during transport.
11.
Keep the electric tool and insert tools in good
condition.
Follow the care and maintenance instructions and replace
insert tools in good time. Never operate the tool when
it is dirty or wet. Dust or dampness on the surface of the
tool makes it slippery and difficult to hold.
Repairs to the tool may be carried out only by an autho-
rised electrical specialist using original Hilti spare parts.
Failure to observe this point may result in damage to the
tool or present a risk of accident. Accordingly, if neces-
sary, have the tool repaired at a Hilti service centre or
authorised Hilti repair workshop.
12.
Avoid short circuiting the terminals of the bat-
tery (accessory).
Short circuiting the battery terminals presents a risk of
fire.
13. Check of proper battery seating in tool.
If the battery is not properly inserted, it can drop out
when working and cause an injury.
14.
Keep the tool out of the reach of children.
Knowledge of the operating instructions is a must if the
tool is to be used without injury or damage to persons
and / or product respectively.
Wear protective
glasses
Wear respiratory protection if the
work causes dust.
