Initial Setup Guidelines
Calibration is your responsibility, check it often.
Although the L5 is an exceptionally rugged laser, it is well worth the effort
to check calibration before you first use it and then at regular intervals to
insure that you are doing the highest quality work possible. Always
check calibration if the laser has been handled roughly. See "checking
and adjusting calibration" on page 14.
Check your setup.
Outdoors: Check your setup from time to time, using enginee red
benchmarks on the jobsite to assure that your work is correct and
matches the design of the job. Realize that even engineered
benchmarks may not be perfect and enough verification must be done to
be confident you are properly set up. If there are not suitable
benchmarks on the site, you should set your own by driving stakes and
recording their elevations, or by marking the laser beam height on stable
objects such as telephone poles, concrete walls, etc. The benchmarks
should be 90
0
apart for greatest accuracy. Having benchmarks to check
is of great value for jobs where setups need to match day after day.
Indoors: Make reference marks, preferably 90
0
apart, once you have set
the laser up either horizontally or vertically. Check your setup from time
to time using the marks as a guide.
Work as close to the laser as possible.
You can work up to 330 feet (100 meters) from the L5 with the system
receiver, or with the MC-1 machine control receiver. As wit h all
instruments, the farther away you work, the more any error can build-up.
Set the laser in a safe place, as close to your work as possible.
Maintain your equipment.
Keeping tripod and mounting hardware tight, and being sure grade rods
are in good condition, can prevent errors and performance problems.
Accessories
Aluminum Tripod
The model T2 adjustable aluminum tripod provides a stable platform for
outdoor or indoor work. Allowing a beam height from approximately 4
feet to 6 feet above the surface it rests on, the T2 is an excellent choice
for typical construction setups. The T2 is a flat head tripod with a 5/8-11
male mounting thread.
Aluminum Grade Rod
The model GR1 grade rod (see photo on left page) is a six foot fixed
height aluminum grade rod with two sets of markings: Feet / Inches /
Eighths of an inch, and Feet / Tenths / Hundredths of a foot.
Ceiling Bracket
The CB bracket replaces the fixed "Y" shaped part of the basic system
mount to allow height adjustment for T-bar ceiling setups and more
flexibility for vertical setups. If you often do T-bar ceiling work, or need
more precise vertical adjustability than the basic mount provides, this
bracket will be a great addition to your system.
Magnetic Target
The MT1 magnetic target is used to display the visible beam of the L5
and provide a relative position indication. Used when installing T-bar
ceiling and steel stud wall framing, the magnetic target allows hands free
alignment.
B50 Rechargeable Battery Kit
Under its battery door, the L5 has a built-in jack for recharging batteries.
The B50 rechargeable battery kit provides two industrial grade Ni-Cd
batteries and a battery charger designed for a 10 hour charge time.
Although Ni-Cad batteries will provide approximately 1/3 the operating
time of alkaline batteries, they are an environmentally friendly upgrade
for your system. Caution: Only charge Ni-Cad batteries!
