• Do not place the laser tool in a manner that may cause someone to unintentionally

look into the laser beam. Serious eye injury may result.

• Do not operate the tool in explosive environments, i.e. in the presence of gases or

flammable liquids.

• Keep the laser tool out of the reach of children and other untrained persons.

• Do not attempt to view the laser beam through optical tools such as telescopes as

serious eye injury may result.

• Always turn the laser tool off when not in use or left unattended for a period of time.

• Remove the batteries when storing the tool for an extended time (more than 3 months)

to avoid damage to the tool should the batteries deteriorate.

6. Operating Instructions

IMPO TANT: It is the responsibility of the user to ensure proper

maintenance of the Self- eveling 3 Dot aser. Conduct periodic

test measurements to ensure the instrument is measuring

accurately and consistently. This is most important if the

instrument has been exposed to extreme temperatures or

moisture. Keep the Self- eveling 3 Dot aser optic lens clean and

inspect for damage.

Battery Installation

To install batteries in the Self- eveling 3 Dot aser:

1. Remove the battery cover, which is located at

the back of the tool, by pressing the battery

cover release found on the left and right side of

the tool and pulling the cover back.

2. Insert 2 “AA” batteries into the battery compart-

ment according to the polarity illustrated inside.

3. Replace the battery cover by seating the bottom door edge first,

then pivoting the battery cover up. Press in the release tabs to

clear the housing as the door closes.

Notes:

• Always check that the locking compensator/power switch is in the

locked position before removing and replacing batteries.

• Use only alkaline batteries.

• Remove the batteries when storing the instrument for an extended

time (more than 3 months) to avoid damage to the tool should the

batteries deteriorate.

Powering the Laser On/Off

Slide the locking compensator up to power on the unit and unlock

the compensator so that the laser can self-level. The status light

will illuminate, and the unit will emit three laser beams (up, front

and down).

Slide the locking compensator down to power off the unit and

engage the pendulum lock. The laser can be safely transported when

the pendulum is locked.

Note: The Self- eveling 3 Dot aser must be within ±5° of level for

the self-leveling feature to function properly. If the instrument is

beyond its 5° self-leveling range, the laser will not self-level, the

laser will flash and the status light will turn red. Once the instrument

has been adjusted to within its 5° self-leveling range, the laser will

self-level, the status light will turn green and the laser light will stop

flashing and remain solid.

Tips from the Pros

• Increasing the Beams’ Visibility – When working in bright

conditions, such as when working near windows or outside walls,

the visibility of the laser beams can be maximized by following

these steps:

• Work towards the laser.

• Use a freestanding target (sold separately).

• Wear laser glasses (sold separately).

Note: aser glasses enhance beam visibility but should never be

used to stare into the beam or be used as safety glasses. Eye

damage may result if these directions are not followed.

Care and Handling

• This Self- eveling 3 Dot aser is a precision tool that must be

handled with care.

• Avoid exposing unit to shock vibrations and extreme temperatures.

• Remove the batteries when storing the unit for an extended time

(more than 3 months) to avoid damage to the unit should the

batteries deteriorate.

• Avoid getting the unit wet.

• Keep the laser unit dry and clean, especially the laser output

window. Remove any moisture or dirt with a soft, dry cloth.

• Do not use harsh chemicals, strong detergents or cleaning

solvents to clean the unit.
