Battery Safety Instructions; Operation - Milwaukee HEAVY DUTY M18 FHIWF1R User Manual

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, fi re and/or serious injury.
Save all warnings and instructions for future reference.
IMPACT WRENCH SAFETY WARNINGS
Wear ear protectors. Exposure to noise can cause hearing loss.
Hold 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.
ADDITIONAL SAFETY AND WORKING INSTRUCTIONS
Use protective equipment. Always wear safety glasses when
working with the product. 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 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 off 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 products
• when setting the product down
Chips and splinters must not be removed while the product is
running.
When working in walls, ceiling, or fl oors, take care to avoid electric
cables and gas pipes or water pipes.
Clamp the workpiece with a clamping device. Unclamped
workpieces can cause severe injury and damage.
Remove the battery pack before starting any work on the product.

BATTERY SAFETY INSTRUCTIONS

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 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 the 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 off immediately with soap and water. In case of eye contact, rinse
thoroughly for at least 10 minutes and immediately seek medical
attention.
No metal parts must be allowed to enter the battery section of the
charger (short circuit risk).
Ambient temperature range for battery during use is between 0 °C
and 40 °C.
Ambient temperature range for battery storage is between 0 °C and
20 °C.
ADDITIONAL BATTERY SAFETY WARNINGS
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 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 product 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: It is recommended after fastening to always check the
torque with a torque wrench.
The fastening torque is aff ected by a wide variety of factors including
the following:
• State of battery charge - When the battery is discharged, the
voltage will drop and the fastening torque will be reduced.
• Operation at speeds - Operating the product at low speeds will
cause a reduction in fastening torques.
• Fastening position - Holding the product 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 affect the
fastening torque (dry or lubricated base, soft or hard base, disc,
seal or washer between the fastener and base material).
AUTO SHUT-OFF MODE
The auto shut-off mode
the spring at the correct compression during rail track maintenance.
The conditions from "Operation" will aff ect the repeatability of this
mode. Always check the tightness of the fastener with a hand-torque
wrench.
