1. GENERAL SAFETY RULES
Read all instructions. Failure to follow all
instructions listed below may result in
hazardous radiation exposure, electric
shock, fire, and/or serious injury.
• CAUTION—use of controls or adjustments or performance
of procedures other than those specified herein may result
in hazardous radiation exposure.
• DO NOT operate this instrument in areas where there is risk
of fire or explosion, like in the presence of flammable liquids,
gases, dust, etc.
• DO NOT disassemble the instrument. There are no user
serviceable parts inside. Disassembling the instrument will
void all warranties on the product.
• DO NOT modify the instrument in any way. Modifying the
instrument may result in hazardous laser radiation exposure.
• To ensure that the instrument is used safely, follow all safety
and operating instructions in this manual. If the instrument
is not used as described in this operation manual, the safety
features of this device may be impaired.
• To avoid personal injuries and damage to the instrument, use
extreme caution when working around hot machine or engine parts,
such as radiators, exhaust manifolds, catalytic converters, etc.
• Repair and servicing must always be performed by qualified
repair personnel. Repairs performed by unqualified personnel
could result in serious injury.
• This instrument is designed for indoor use at temperatures
between 32°F and 122°F (0°C to 50°C), altitudes up to 6500
ft. (2,000 m), and 10% to 90% relative humidity.
2. LASER SAFETY RULES
This label is on your
l a s e r i n s t r u m e n t
f o r y o u r s a f e t y.
ALWAYS BE AWARE
of its location when
u s i n g t h e t o o l .
DO NOT direct the laser beam at persons or
animals and do not stare into the laser beam
yourself. This tool produces class 2 laser
radiation and complies with 21 CFR 1040.10 and
1040.11 except for deviations pursuant to Laser
Notice No. 50, dated June 24, 2007. This can lead
to persons being blinded.
Working safely with this instrument is possible only when the
operating and safety information are read completely and the
instructions contained therein are strictly followed.
•
Never make the warning labels on the instrument unrecognizable.
• Never aim the beam at a workpiece with a reflective surface.
• Mirrors or similar reflective surfaces are not recommended for laser
use, as these could reflect the beam back towards the operator.
• Do not point the laser beam at persons or animals and do not look
into the laser beam yourself, not even from a long distance.
• Do not use laser viewing glasses as safety goggles, because they
do not protect against laser radiation.
• Do not allow children to use the measuring tool without supervision.
They could unintentionally blind other people.
• ALWAYS: Make sure that any bystanders in the vicinity of use are
made aware of the dangers of looking directly into the instrument.
