The dust produced when using the product 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).
Turn o
ff the product immediately if the insertion tool stalls.
Do not turn on the product 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:
● The insertion tool is tilted in the workpiece to be machined.
● The insertion tool has pierced through the material to be
machined.
● The power tool is overloaded.
Do not reach into the product while it is running.
The insertion tool may become hot during use.
WARNING! Danger of burns
● when changing tools
● when setting the product down
Chips and splinters must not be removed while the product is
running.
When working in walls, ceilings, or
fl oors, take care to avoid
electric cables and gas pipes 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
product.
Do not dispose of used battery packs in the household refuse
or by burning them. MILWAUKEE distributors o
ff er to retrieve
old batteries to protect the environment.
Do not store the battery pack together with metal objects (short
circuit risk).
Use only M18 System chargers for charging M18 System
battery packs. Do not use battery packs from other systems.
Never break open battery packs and chargers, and store them
only in dry rooms. Keep battery packs and chargers 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 o
ff immediately with soap and water. In case
of eye contact, rinse thoroughly for at least 10 minutes and
immediately seek medical attention.
ADDITIONAL BATTERY SAFETY WARNINGS
WARNING! To reduce the risk of fi re, personal injury,
and product damage due to a short circuit, never immerse
the tool, battery pack, or charger in
fl uid or allow fl uid to fl ow
inside them. Corrosive or conductive fl uids, such as seawater,
certain industrial chemicals, and bleach or bleach-containing
products, etc., can cause a short circuit.
SPECIFIED CONDITIONS OF USE
The cordless impact wrench can be used to tighten and loosen
nuts and bolts wherever no mains connection is available.
Do not use the product for any other purpose.
OPERATION
NOTE: After fastening, always check the torque with a torque
wrench.
The fastening torque is a
ff ected by a wide variety of factors,
including the following:
● State of battery charge – When the battery is discharged,
the voltage drops and the fastening torque is reduced.
● Operation at speeds – Operating the product at low speeds
causes a reduction in fastening torques.
● Fastening position – Holding the product or the driving
fastener in various angles affects the torque.
● Drive accessory or 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 or nut – Fastening torques may differ according to the
diameter of the nut or bolt, the class of the nut or bolt, and
the length of the nut or 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
affect the fastening torque (dry or lubricated base, soft or
hard base, disc, seal, or washer between the fastener and
base material).
In mode:
Auto shut o ff - In forward, the product runs at a reduced RPM
and then shuts o ff once the torque is achieved.
Bolt removal - In reverse, the product runs at full RPM and IPM
until the nut breaks free from the joint. Then, the product slows
to a reduced RPM for better control in removing the nut.
IMPACTING TECHNIQUES
The longer that a bolt, screw, or nut is impacted, the tighter it
will become.
To help prevent damaging the fasteners or workpieces, avoid
excessive impacting.
Be 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 the fasteners are not tight enough, increase the impacting
time.
Oil, dirt, rust, or other matter on the threads or under the head
of the fastener a
ff ects the degree of tightness.
The torque required to loosen a fastener averages 75% – 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
fi nal tightening.
