DO NOT use the laser viewing glasses as
sun glasses or in traffic. The laser viewing
glasses do not provide complete UV protection
and reduce color perception.
DO NOT use any optical tools such as, but
not limited to, telescopes or transits to view
the laser beam. Serious eye injury could result.
DO NOT stare directly at the laser beam
or project the laser beam directly into the
eyes of others. Serious eye injury could result.
Use caution when using measuring tools
in the vicinity of electrical hazards.
If glass light house breaks when dropped,
broken glass can cause laceration hazard
and unit to lose its IP rating. Contact
customer service immediately.
Protect the measuring tool
against heat, e.g., against
continuous intense sunlight, fire,
water, and moisture. Danger of explosion.
Magnets
Keep the tool and laser
target away from cardiac
pacemakers. The magnets of
the tool and laser target plate
generate a field that can
impair the function of cardiac
pacemakers.
Keep the tool and laser target away from
magnetic data medium and magnetically-
sensitive equipment. The effect of the
magnets of the tool and laser target plate can
lead to irreversible data loss.
Placing an external magnetic field in close
proximity with the GRL 500 may energize
the output terminals. Risk of fire hazard.
Noise Information
Measured sound values determined
according to EN 60745. Typically the
A-weighted sound pressure level of the
measuring tool is less than 110 dB (A).

Use and Care
Use the correct tool for your application.
The correct tool will do the job better and safer.
Do not use the tool if the switch does not
turn it on and off. Any tool that cannot be
controlled with the switch is dangerous and
must be repaired.
Store idle tool out of the reach of children
and do not allow persons unfamiliar with
the tool or these instructions to operate
the tool. Tools are dangerous in the hands of
untrained users.
Maintain tools. Check for misalignment
or binding of moving parts, breakage of
parts and any other condition that may
affect the operation. If damaged, get the
tool repaired before use. Many accidents
are caused by poorly maintained tools.
Use the tool, accessories, etc., in
accordance with these instructions and
in the manner intended for the particular
type of tool, taking into account the
working conditions and the work to be
performed. Use of the tool for operations
different from those intended could result in a
hazardous situation.
Service
Have your tool serviced by a qualified
repair person using only identical
replacement parts. This will ensure that the
safety of the tool is maintained.
Develop a periodic maintenance schedule
for tool. Follow checking and recalibration
procedures outlined in the instruction manual.
When cleaning a tool be careful not to
disassemble any portion of the tool
since internal wires may be misplaced or
pinched or may be improperly mounted.
Certain cleaning agents such as gasoline,
carbon tetrachloride, ammonia, etc. may
damage plastic parts.
