f) If the battery is too hot to touch it may be defective. Place the tool in
a location where it can be kept under observation, well away from
flammable materials, and allow it to cool down. Contact Hilti Service
after the battery has cooled down.
2.2.4 Electrical safety
Before beginning work, check the working area (e.g. using a metal
detector) to ensure that no concealed electric cables or gas and water
pipes are present. External metal parts of the power tool may become live,
for example, when an electric cable is damaged accidentally. This presents
a serious risk of electric shock.
2.2.5 Personal protective equipment
The user and any other persons in the vicinity must wear ANSI Z87.1-
approved eye protection, a hard hat, ear protection, protective gloves
and breathing protection while the machine is in use.

The product described here is a hand-held cordless impact wrench. It is
suitable for tightening and releasing nuts, bolts, anchors and wood screws.
Observe the national health and safety requirements.
Do not use the battery as a power source for other unspecified appliances.
To avoid the risk of injury, use only genuine Hilti accessories and insert tools.
The power tool should not be used for applications that require a precise
torque. For applications which require a precise torque or where only a
special limited torque is permitted, there is a risk of over-tightening and
damage to the screw or workpiece. For these types of application, use a
