WARNING
The vibration and noise emission level given in this information sheet has been measured in accordance with a standardized test given in EN 62841 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.
The declared vibration and noise emission level represents the main applications of the tool. However if the tool is used for diﬀerent applications, with diﬀerent accessories or poorly maintained, the vibration and noise emission may diﬀer. This may signiﬁcantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration and noise should also take into account the times when the tool is switched oﬀ or when it is running but not actually doing the job. This may signiﬁcantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the eﬀects of vibration and/or noise such as: maintain the tool and the accessories, keep the hands warm, organization of work patterns.

WARNING Read all safety warnings, instructions, illustrations and speciﬁcations provided with this power tool. Failure to follow all instructions listed below may result in electric shock, ﬁre and/or serious injury.
Save all warnings and instructions for future reference.

IMPACT WRENCH SAFETY WARNINGS

Hold the power tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring. Fasteners contacting a „live“ wire may make exposed metal parts of the power tool „live“ and could give the operator an electric shock.
Wear ear protectors. Exposure to noise can cause hearing loss.

ADDITIONAL SAFETY AND WORKING INSTRUCTIONS

Use protective equipment. Always wear safety glasses when working with the machine. The use of protective clothing is recommended, such as dust mask, protective gloves, sturdy non-slip footwear, helmet and ear defenders.
The dust produced when using this tool may be harmful to health. Do not inhale the dust. Wear a suitable dust protection mask.
Do not machine any materials that present a danger to health (e.g. asbestos).
Switch the device oﬀ immediately if the insertion tool stalls! Do not switch the device on again while the insertion tool is stalled, as doing so could trigger a sudden recoil with a high reactive force. Determine why the insertion tool stalled and rectify this, paying heed to the safety instructions.
The possible causes may be:

it is tilted in the workpiece to be machined
it has pierced through the material to be machined
the power tool is overloaded
Do not reach into the machine while it is running. The insertion tool may become hot during use.
when changing tools
when setting the device down

Chips and splinters must not be removed while the machine is running.
When working in walls ceiling, or ﬂ oor, take care to avoid electric cables and gas or waterpipes.
Clamp your workpiece with a clamping device. Unclamped workpieces can cause severe injury and damage.
Remove the battery pack before starting any work on the machine.
Do not dispose of used battery packs in the household refuse or by burning them. Milwaukee Distributors oﬀ er to retrieve old batteries to protect our environment.
Do not store the battery pack together with metal objects (short circuit risk).
Use only System M18 chargers for charging System M18 battery packs. Do not use battery packs from other systems.
Never break open battery packs and chargers and store only in dry rooms. Keep dry at all times.
Battery acid may leak from damaged batteries under extreme load or extreme temperatures. In case of contact with battery acid wash it oﬀ immediately with soap and water. In case of eye contact rinse thoroughly for at least 10 minutes and immediately seek medical attention.
M18 BIW12: Do not use battery M18HB12 with this machine!

Warning! To reduce the risk of ﬁ re, personal injury, and product damage due to a short circuit, never immerse your tool, battery pack or charger in ﬂuid or allow a ﬂuid to ﬂ ow inside them. Corrosive or conductive ﬂuids, such as seawater, certain industrial chemicals, and bleach or bleach containing products, etc., can cause a short circuit.

SPECIFIED CONDITIONS OF USE

OPERATION

Note: It is recommended after fastening to always check the torque with a torque wrench.
The fastening torque is aﬀected by a wide variety of factors including the following.

State of battery charge – When the battery is discharged voltage will drop and the fastening torque will be reduced.
Operation at speeds – Operating the tool at low speeds will cause a reduction in fastening torques.
Fastening position – Holding the tool or the driving fastener in various angles will aﬀect the torque.
Drive accessory/socket – Failure to use the correct size accessory or socket, or a non-impact rated accessory may cause a reduction in the fastening torque.
Use of accessories and extensions – Depending on the accessory or extension ﬁtment can reduce the fastening force of the impact wrench.
Bolt/Nut – Fastening torques may diﬀer according to the diameter of the nut or bolt, the class of nut/bolt and the length of nut/bolt.
Condition of the fastener – Contaminated, corroded, dry or lubricated fasteners may vary the fastening torques.
Condition and base material – The base material of the fastener and any component in between the surfaces may eﬀ ect the fastening torque (dry or lubricated base, soft or hard base, disc, seal or washer between fastener and base material).

IMPACTING TECHNIQUES

The longer a bolt, screw, or nut is impacted, the tighter it will become.
To help prevent damaging the fasteners or workpieces, avoid excessive impacting.
Be particularly careful when impacting smaller fasteners because they require less impacting to reach optimum torque.
Practice with various fasteners, noting the length of time required to reach the desired torque.
Check the tightness with a hand-torque wrench.
If the fasteners are too tight, reduce the impacting time.
If they are not tight enough, increase the impacting time.
Oil, dirt, rust or other matter on the threads or under the head of the fastener aﬀ ects the degree of tightness.
The torque required to loosen a fastener averages 75% to 80% of the tightening torque, depending on the condition of the contacting surfaces.
On light gasket jobs, run each fastener down to a relatively light torque and use a hand torque wrench for ﬁnal tightening.

BATTERIES

Battery packs which have not been used for some time should be recharged before use.
Temperatures in excess of 50°C (122°F) reduce the performance of the battery pack. Avoid extended exposure to heat or sunshine (risk of overheating).
The contacts of chargers and battery packs must be kept clean.
For an optimum life-time, after use, the battery packs have to be fully charged.
To obtain the longest possible battery life remove the battery pack from the charger once it is fully charged.
For battery pack storage longer than 30 days:
Store the battery pack where the temperature is below 27°C and away from moisture
Store the battery packs in a 30% – 50% charged condition Every six months of storage, charge the pack as normal.

BATTERY PACK PROTECTION

In extremely high torque, binding, stalling and short circuit situations that cause high current draw, the tool will vibrate for about 2 seconds and then the tool will turn OFF.
To reset, release the trigger.
Under extreme circumstances, the internal temperatur of the battery could become to high. If this happens, the battery will shut down.
Place the battery on the charger to charge and reset it.

TRANSPORTING LITHIUM BATTERIES
