• Do not operate the laser in explosive atmospheres,
such as in the presence of ammable liquids, gases,
or dust. This tool may create sparks which may ignite the
dust or fumes.
• Store an idle laser out of reach of children and other
untrained persons. Lasers are dangerous in the hands of
untrained users.
• Tool service MUST be performed by qualied repair
personnel. Service or maintenance performed by unqualied
personnel may result in injury. To locate your nearest Stanley
service centre go to http://www.2helpU.com.
• Do not use optical tools such as a telescope or transit to
view the laser beam. Serious eye injury could result.
• Do not place the laser in a position which may cause
anyone to intentionally or unintentionally stare into the
laser beam. Serious eye injury could result.
• Do not position the laser near a reective surface which
may reect the laser beam toward anyone’s eyes. Serious
eye injury could result.
• Turn the laser off when it is not in use. Leaving the laser
on increases the risk of staring into the laser beam.
• Do not modify the laser in any way. Modifying the tool may
result in hazardous laser radiation exposure.
• Do not operate the laser around children or allow
children to operate the laser. Serious eye injury may result.
• Do not remove or deface warning labels. If labels are
removed, the user or others may inadvertently expose
themselves to radiation.
• Before use, verify the thermometer’s operation by measuring
a known temperature.
• Do not direct the laser beam toward aircraft or moving
vehicles. Serious eye injury may result.
• Do not splash or immerse the unit in water.
• The measurement result of an object with high emissivity
may be lower than the actual temperature of that object.
Heat injury may result.
CAUTION: The laser should be protected against the
following:
• Electro magnetic elds (created by arc welders,
induction heaters and similar items.)
• Thermal shock caused by large or sudden
ambient temperature changes. For best accuracy
allow 30 minutes for the thermometer to stabilize
the temperature before use.
• Do not leave the laser on or near objects of
high temperature.
Personal Safety
• Stay alert, watch what you are doing, and use common sense
when operating the laser. Do not use the laser when you are
tired or under the inuence of drugs, alcohol, or medication.
A moment of inattention while operating the laser may result
in serious personal injury.
• Use personal protective equipment. Always wear eye
protection. Depending on the work conditions, wearing
protective equipment such as a dust mask, non-skid
safety shoes, hard hat, and hearing protection will reduce
personal injury.
Tool Use and Care
• Do not use the laser if it will not turn on or off. Any tool that
cannot be controlled with the switch is dangerous and must
be repaired.
• Follow instructions in the Maintenance section of this
manual. Use of unauthorised parts or failure to follow
Maintenance instructions may create a risk of electric shock
or injury.
Battery Safety
WARNING:
Batteries can explode, or leak, and can cause
injury or re. To reduce this risk:
• Carefully follow all instructions and warnings on the battery
label and package.
