IMPORTANT SAFETY
INSTRUCTIONS
Read all safety warnings and all instruc-
the warnings and instructions may result in electric
shock, re and/or serious injury. Save all warnings
and instructions for future reference.
WORK AREA SAFETY
• To reduce the risk of injury, close supervision is
necessary when an appliance is used near children.
• Store idle light out of reach of children. Warm
lights can become hazardous in the hands of chil-
dren.
ELECTRICAL SAFETY
• Power cord plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodied plugs and matching outlets will
reduce risk of electric shock.
• Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
• Suitable for rain and wet locations. Store indoors. Water and dust resistant.
• To reduce the risk of electric shock, do not put
light in water or other liquid. Do not place or store
appliance where it can fall or be pulled into a tub or
sink.
• Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords
increase the risk of electric shock.
• Arrange cords carefully to avoid hazardous
environments. Tripping or snagging on cords can
cause injury and product damage. Do not allow
cords to run through puddles or across wet ground.
• Do not unplug by pulling on the cord. To unplug,
grasp the plug, not the cord.
• Unplug the cord from outlet when not in use and
before servicing or cleaning.
• Always use a suitable extension cord to reduce
the risk of electric shock.
• If operating a light in a damp location is unavoid-
able, use a ground fault circuit interrupter (GFCI)
protected supply. Use of an GFCI reduces the risk
of electric shock.
PERSONAL SAFETY
• Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of the
light in unexpected situations.
• Do not use on a ladder or unstable support.
Stable footing on a solid surface enables better
control of the light in unexpected situations.
tions. Failure to follow
BATTERY TOOL USE AND CARE
• Recharge only with the charger specied by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of re when used
with another battery pack.
• Use light only with specically designated bat-
tery packs. Use of any other battery packs may
create a risk of injury and re.
• When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal
to another. Shorting the battery terminals together
may cause burns or a re.
• Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
• Do not use a battery pack or tool that is damaged or modied. Damaged or modied batteries
may exhibit unpredictable behavior resulting in re,
explosion or risk of injury.
• Do not expose a battery pack or tool to re or
excessive temperature. Exposure to re or tem-
perature above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not
charge the battery pack or tool outside the
temperature range specied in the instructions.
Charging improperly or at temperatures outside
the specied range may damage the battery and
increase the risk of re.
SERVICE
• Have your light serviced by a qualied repair
person using only identical replacement parts.
This will ensure that the safety of the light is main-
tained.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
SPECIFIC SAFETY RULES
•Chemical Burn Hazard. Keep batteries away
from children.
•This tool contains a lithium button/coin cell
battery. A new or used battery can cause severe
internal burns and lead to death in as little as 2
hours if swallowed or enters the body. Always
secure the battery cover with all screws. If it does
not close securely, stop using the tool, remove the
batteries, and keep it away from children. If you think
batteries may have been swallowed or entered the
body, seek immediate medical attention.
•Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.

GROUNDING
Improperly connecting the ground-
electric shock. Check with a qualied electrician
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug provided with the tool. Never remove the grounding
prong from the plug. Do not use the tool if the
cord or plug is damaged. If damaged, have it
repaired by a MILWAUKEE service facility before
use. If the plug will not t the outlet, have a
proper outlet installed by a qualied electrician.
Grounded Tools (Three-Prong Plugs)
Tools marked “Grounding Required”
have a three wire cord and three
prong grounding plug. The plug
must be connected to a properly
grounded outlet (See Figures A and
B). If the tool should electrically malfunction or break down, grounding
provides a low resistance path to
carry electricity away from the user,
reducing the risk of electric shock.
The grounding prong in the plug is
connected through the green wire
inside the cord to the grounding
system in the tool. The green wire in the cord must
be the only wire connected to the tool's grounding
system and must never be attached to an electrically
“live” terminal.
Your tool must be plugged into an appropriate outlet,
properly installed and grounded in accordance with
all codes and ordinances. The plug and outlet should
look like those in Figures A and B.
Double Insulated Tools (Two-Prong Plugs)
Tools marked “Double Insulated”
do not require grounding. They
have a special double insulation
system which satises OSHA requirements and complies with the
applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association and the National Electrical
Code. Double Insulated tools may be used in either
of the 120 volt outlets shown in Figures C and D.

Grounded tools require a three wire extension
EXTENSION CORDS
cord. Double insulated tools can use either a two
or three wire extension cord. As the distance from
the supply outlet increases, you must use a heavier
gauge extension cord. Using extension cords with
inadequately sized wire causes a serious drop in
voltage, resulting in loss of power and possible tool
damage. Refer to the table shown to determine the
required minimum wire size.
The smaller the gauge number of the wire, the greater
the capacity of the cord. For example, a 14 gauge
cord can carry a higher current than a 16 gauge cord.
When using more than one extension cord to make
up the total length, be sure each cord contains at
least the minimum wire size required. If you are using
one extension cord for more than one tool, add the
nameplate amperes and use the sum to determine
the required minimum wire size.
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors, be sure
it is marked with the sufx “W” to indicate that it is
acceptable for outdoor use.
• Be sure your extension cord is properly wired and in
good electrical condition. Always replace a damaged
extension cord or have it repaired by a qualied
person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.
• When stringing lights together, consider the total
Amperes draw when selecting the extension cords.
