Safety Precautions
WARNING
• There is a risk of fire, electric shock or ph ysical harm if y ou attempt to disassemble or repair the instrument yourself.
Repairs are to be carried out by TOPCON or an authorized dealer ONLY!
• Laser beams can be dangerous and can cause eye injury if used incorrectly.
Never attempt to repair the instrument yourself.
• Laser beams can be dangerous. They can cause eye injury.
Do not stare into beam or view directly with optical instruments.
• Risk of fire or electric shock.
Do not use a wet battery.
• May ignite explosively.
Never use an instrument near flammable gas or liquid matter, and do not use in a coal
mine.

CAUTION
Use of controls, adjustment to the laser , or the performing of any procedures other than
those specified herein may result in hazardous radiation exposure.
DO NOT allow anyone to work directly in the path of the laser beam.
Always make sure the laser is operating above the height of your crews heads.
Exposure to laser light may cause momentary blindness. Always use caution when operating equipment near a laser.
Do not allow skin or clothing to come into contact with acid from the batteries. If this occurs, wash off with copious amounts of water and seek medical attention.
Damaged or broken carrying cases may fall open causing injury, or damage to the laser.
Do not use a carrying case with damaged belts, grips or latches.
It could be dangerous if the instrument falls off of its mount. Please chec k that y ou have
mounted the instrument to the wall mount or tripod securely and correctly.
An unstable tripod can pose a potential risk of injury or damage to the laser.
Always check that screws or leg locks are tight and tripod is sitting firmly.
Please note that the tips of tripod can be hazardous and be aware of this when setting
up or carrying the tripod.

1
Set the RL-H2Sa on a tripod or flat surface.
(See "Instrument Set-up Procedure " on page
12.)
2
Turn the instrument ON and enter a grade if
desired. (See "Entering Grade " on page 18.)
3
Set beam rotation to the desired speed.
(See "Changing rotation speed " on page 16.)
4
Set the electronic beam shutter (mask) for specific quadrants if desired. (See "Masking
(Laser beam shutter) " on page 21.)
5
Turn on LS-70 laser sensor. If high-precision
detection is desired, select that setting on the LS-70.( See "Standard / Optional Accessories " on page 36 for more information.)
6
Use the LS-70 to intercept the rotating laser beam to check a specific elevation.

Preparation and Functions
Battery Installation
For battery installation instructions, see "Maintaining Power Sources " on page 22.
Instrument Set-up Procedure
1
Set the instrument on any smooth surface that is within ±5° of true level. The RL-H2Sa
auto-level system will not function if the unit is placed more that 5° out of level. For best
operation, it is recommended that it be mounted to a tripod. Beam slope can be set in the
X-axis (See "Entering Grade " on page 18.

Battery Warning Indicator
The Battery warning indicator indicates the battery power remaining.
Battery is sufficient.
The power is low, but laser is still usable.
In this state, the laser will transmit the battery warning signal to laser sensor.
AC/DC converter AD-9B or AD-7C is available for continuing the operation.
Dead batteries. The rotary head stops and no beam is emitted from the laser.
Blinking
Recharge the battery (BT-51Q Ni-MH rechargeable battery) or replace the dry batteries with
new ones. (The laser will shut down a few minutes after the blinking indicator comes on.)
AC/DC conv erter AD-9B or AD-7C is availab le but it is necessary to turn OFF the instrument
once, and turn ON the instrument again.
Note
• When BT-51Q (Ni-MH rechargeable battery) is used, the blinking period will be
shorter because of the characteristic of the battery.
• The LS-70A and LS-70B laser sensors can detect and signal low power state
of laser.
