b) Check that the insert tools used are compatible
with the chuck system and that they are secured
in the chuck correctly.
c) Ensure fastener and attachment will withstand
the level of torque generated by the tool. Ex-
cessive torque may overstress, strip or damage the
fastener/attachment and possibly lead to personal
injury.
2.2.3 Cordless tool use and care
a) Do not expose batteries to high temperatures and
keep them away from fire. This presents a risk of
explosion.
b) Do not disassemble, squash or incinerate batter-
ies and do not subject them to temperatures over
80°C. This presents a risk of fire, explosion or injury
through contact with caustic substances.
c) Observe the special guidelines applicable to the
transport, storage and use of Li-ion batteries.

3 Description

3.1 Use of the product as directed
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 tool with a predefined torque setting to prevent
over-tightening.
The power tool is designed for professional use and may be operated, serviced and maintained only by trained,
authorized personnel. This personnel must be informed of any special hazards that may be encountered. The power
tool and its ancillary equipment may present hazards when used incorrectly by untrained personnel or when used not
as directed.
3.2 The items supplied include:
1 Power tool
1 Operating instructions
NOTE
Approved accessories are available from your Hilti Center or can be ordered online at www.hilti.com.
3.3 Additional items required for operating the tool
A suitable battery of the specified type (see table in the Technical Data section) and a suitable battery charger from
the C 4⁄36 series.
3.4 Charge state and overheating indicator display on the Li-ion battery
When the lithium-ion battery is in use, the charge status can be indicated by gently pressing one of the battery release
buttons (press until resistance is felt – do not release the battery). The display on the rear of the battery provides the
following information:
d) Do not charge or continue to use damaged bat-
teries (e.g. batteries with cracks, broken parts,
bent or pushed-in and/or pulled-out contacts).
e) 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 ma-
terials, 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 suitable eye protection, a hard hat, ear protec-
tion, protective gloves and breathing protection while
the tool is in use.
