IMPORTANT SAFETY INSTRUCTIONS
WARNING READ ALL SAFETY WARNINGS AND INSTRUCTIONS. Failure to
follow the warnings and instructions may result in electric shock, fi re and/or serious injury.
Save these instructions - This operator’s manual contains important safety and operating
instructions for MILWAUKEE Laser Temp-Gun™ Thermometers. Before using the Temp-Gun™,
read this operator’s manual, your battery pack and charger operator’s manual, and all labels
on the battery pack, charger and Temp-Gun™.
FUNCTIONAL DESCRIPTION
PERSONAL SAFETY
LASER SAFETY
WORK AREA SAFETY
• Laser light - Do not stare into beam or view
directly with optical instruments. Do not point
laser light at others. Laser light can cause eye
damage.
• Avoid exposure to laser radiation. Laser may
emit hazardous radiation.
• Do not point laser at refl ective surfaces. Un-
predictable results may occur.
• Keep children and bystanders away while
operating Temp-Gun™. Store idle Temp-Gun™
out of the reach of children and do not allow
persons unfamiliar with the tool or these in-
structions to operate them.
• Avoid dangerous environments. Do not use in
rain, snow, damp or wet locations. Do not use in
the presence of explosive atmospheres (gaseous
fumes, dust or fl ammable materials) because
sparks may be generated when inserting or re-
moving battery pack, possibly causing fi re.
• Stay alert, watch what you are doing and use
common sense when operating Temp-Gun™.
Do not use while you are tired or under the
infl uence of drugs, alcohol or medication.
A moment of inattention may result in serious
personal injury.
• Do not overreach. Keep proper footing and
balance at all times. This enables better control
in unexpected situations.
BATTERY USE AND CARE
• Under abusive conditions, liquid may be
ejected from the battery, avoid contact. If
contact accidentally occurs, fl ush with water. If
liquid contacts eyes, additionally seek medical
help. Liquid ejected from the battery may cause
irritation or burns.
SERVICE
• Have your Temp-Gun™ serviced by a qualifi ed
repair person using only identical replacement
parts. This will ensure that the safety of the tool
is maintained.
• Do not disassemble. Incorrect reassembly may
result in the risk of electric shock or fi re. If it is dam-
aged, take it to a MILWAUKEE service facility.
• Store in a cool, dry place. Do not store where
temperatures may exceed 120°F (50°C) such as
in direct sunlight, a vehicle or metal building during
the summer.
• Do not remove or deface labels. Maintain
labels and nameplates. These carry important
information. If unreadable or missing, contact
a MILWAUKEE service facility for a free
replacement.
• Recharge only with the charger specifi ed by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of fi re
when used with another battery pack.
• Use power tools only with specifi cally desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and fi 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 termi-
nals together may cause burns or a fi re.
