SAFETY WARNINGS
WARNING
warnings and instructions may result in electric
shock, fi re and/or serious injury. Save these instruc-
tions - This operator’s manual contains important
safety and operating instructions for the MILWAUKEE Infrared Temp-Gun™ Thermometer.
Before using the Temp-Gun™, read this operator’s manual and all labels on the Temp-Gun™.
Read all safety warnings and instructions. Failure to follow the
LASER 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. Unpre-
dictable results may occur.
WORK AREA SAFETY
• Keep children and bystanders away while operating Temp-Gun™. Store idle Temp-Guns™ out
of the reach of children and do not allow persons
unfamiliar with the tool or these instructions 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 removing batteries, possibly causing fi re.
PERSONAL SAFETY
• 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 u-
ence 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
• 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 terminals together
may cause burns or a fi re.
• Under abusive conditions, liquid may be ejected
from the battery, avoid contact. If contact accidentally occurs, fl ush with water. If liquid con-
tacts 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-
2
aged, take it to a MILWAUKEE service facility.
• Store in a cool, dry place. Do not store where
temperatures may exceed 140°F (60°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.
