1. Turn the laser upside down.
2. On the bottom of the laser, lift up the latch to open the battery
compartment cover (Figure B1).
3. Insert two new, high-quality, name brand AA batteries, making
sure to position the - and + ends of each battery as noted
inside the battery compartment (Figure B2).
4. Push the battery compartment cover closed until it snaps in
place (Figure B3).
When the laser is not in use, keep the Power/Transport Lock
switch in the center (OFF) position (Figure A2) to save
battery power.
Turning the Laser On
1. Place the laser on a smooth, flat, level surface, with the
laser facing straight ahead toward the opposing wall (0º
position).
2. Turn the laser ON to display the horizontal and vertical
laser beams. Either:
• Move the Power/Transport Lock switch to the left to keep
the pendulum locked and display the cross beams in
manual mode (Figure A1).
• Move the Power/Transport Lock switch to the right to
unlock the pendulum and display the cross beams in
self-leveling mode (Figure A3).
3. Check the horizontal and vertical laser beams.
• If the laser is tilted so much that it cannot self-level
(> 4°), or the laser is not level in manual mode, the laser
beams will flash.
• If the laser beams ash, the laser is not level (or plumb)
and should NOT BE USED for determining or marking
level or plumb. Try repositioning the laser on a level
surface.
4. If ANY of the following statements are TRUE, continue with
the instructions for Checking Laser Accuracy BEFORE
USING THE LASER for a project.
• This is the first time you are using the laser (in case the
laser was exposed to extreme temperatures).
• The laser has not been checked for accuracy in a
while.
• The laser may have been dropped.
Checking Laser Accuracy
The laser tools are sealed and calibrated at the factory. It
is recommended that you perform an accuracy check prior
to using the laser for the rst time (in case the laser was
exposed to extreme temperatures) and then regularly to
ensure the accuracy of your work. When performing any of
the accuracy checks listed in this manual, follow these
guidelines:
• Use the largest area/distance possible, closest to the
operating distance. The greater the area/distance, the
easier to measure the accuracy of the laser.
• Place the laser on a smooth, at, stable surface that is
level in both directions.
• Mark the center of the laser beam.
Horizontal Beam - Scan Direction
Checking the horizontal scan calibration of the laser requires
two walls at least 30′ (9m) apart. It is important to conduct
a calibration check using a distance no shorter than the distance
of the applications for which the tool will be used.
1. Place the back of the laser against a wall and facing straight
ahead toward the opposing wall (Figure D1).
2. Move the Power/Transport Lock switch to the right (Figure
A3)to turn the laser ON in self-leveling mode and display
the horizontal and vertical beams.
3. Turn the laser 45º counter-clockwise so that the right-most
end of the laser line is displayed on the wall.
4. Mark a on the center of the beam on the wall.
5. Turn the laser 90º clockwise so that the left-most end of
the laser line is displayed near a(Figure D2).
6. Mark b on the center of the beam on the wall.
7. Measure the vertical distance between aand b.

Using the Laser
Operating Tips
• Always mark the center of the beam created by the laser.
• Extreme temperature changes may cause movement of
internal parts that can affect accuracy. Check your accuracy
often while working.
• If the laser is ever dropped, check to make sure it is still
calibrated.
• As long as the laser is properly calibrated, the laser is self-
leveling. Each laser is calibrated at the factory to nd level as
long as it is positioned on a at surface within average ± 4°
of level. No manual adjustments are required.
• Use the laser on a smooth, at, level, surface.
Turning the Laser Off
Slide the Power/Transport Lock switch to the OFF position
(Figure A2) when the laser is not in use. If the switch is not
placed in the OFF position, the laser will not turn off.
Using the Laser with the Bracket
A bracket (Figure G) is included with the laser so you can
easily attach the laser to a stud, ceiling grid, or pole.
1. Securely attach the laser to the bracket.
• Using the 1/4-20 thread on the bottom, side, or back of the
laser (Figure C), position the laser on the 1/4-20 thread
on the bracket arm (Figure G1).
• Turn the laser knob (Figure G2) clockwise to lock the
laser on the 1/4-20 thread on the bracket arm.
2. If needed, change the height or position of the laser on the
bracket.
• Turn the adjustment knob (Figure G3) counter-clockwise
to loosen the bracket arm.
• Slide the bracket arm up or down to the desired height
(Figure G4). To change the bracket from 90°to 180°,
slide the bracket arm to the top of the bracket and then flip
the arm to the right (Figure G5).
• Turn the adjustment knob (Figure G3) clockwise to lock
the bracket arm in place.
3. Use the bracket’s clamp (Figure G6) to hold the laser in
place on a stud, ceiling grid, or pole.
• If necessary, rotate the clamp so it is positioned at the
correct angle for attaching to the object. While holding the
bracket arm with one hand, use your other hand to turn
the clamp (Figure G7).
• Position the bracket’s clamp around the stud, ceiling
grid, or pole.
• Turn the clamp knob (Figure G8) clockwise until the
clamp is tight around the object and the bracket is held
in place.

Vertical Beam - Plumb
Checking the vertical (plumb) calibration of the laser can be
most accurately done when there is a substantial amount of
vertical height available, ideally 30′ (9m), with one person on
the oor positioning the laser and another person near a ceiling
to mark the position of the beam. It is important to conduct
a calibration check using a distance no shorter than the distance
of the applications for which the tool will be used.
1. On the oor between two walls, mark a 5 ft. (1.5 m) line
that is parallel to the adjacent wall (Figure F1).
2. Move the Power/Transport Lock switch to the right (Figure
A3)to turn the laser ON in self-leveling mode and display
the horizontal and vertical beams.
3. Place the laser at one end of the line on the oor, making
sure the vertical laser beam is aligned and centered on the
line.
4. Where the vertical laser beam appears on the ceiling, mark
a. (This should be directly over the midpoint of the line on
the oor.)
5. Move the laser to the other end of the line on the oor
(Figure F2).
6. Where the vertical laser beam appears on the ceiling, mark
b, directly beside the rst mark a.
7. Measure the distance between aand b.
8. If your measurement is greater than the Allowable
Distance Between aand bfor the corresponding
Ceiling Height Din the following table, the laser must be
serviced at an authorized service center.

Using the Laser
Operating Tips
• Always mark the center of the beam created by the laser.
• Extreme temperature changes may cause movement of
internal parts that can affect accuracy. Check your accuracy
often while working.
• If the laser is ever dropped, check to make sure it is still
calibrated.
• As long as the laser is properly calibrated, the laser is self-
leveling. Each laser is calibrated at the factory to nd level as
long as it is positioned on a at surface within average ± 4°
of level. No manual adjustments are required.
• Use the laser on a smooth, at, level, surface.
Turning the Laser Off
Slide the Power/Transport Lock switch to the OFF position
(Figure A2) when the laser is not in use. If the switch is not
placed in the OFF position, the laser will not turn off.
Using the Laser with the Bracket
A bracket (Figure G) is included with the laser so you can
easily attach the laser to a stud, ceiling grid, or pole.
1. Securely attach the laser to the bracket.
• Using the 1/4-20 thread on the bottom, side, or back of the
laser (Figure C), position the laser on the 1/4-20 thread
on the bracket arm (Figure G1).
• Turn the laser knob (Figure G2) clockwise to lock the
laser on the 1/4-20 thread on the bracket arm.
2. If needed, change the height or position of the laser on the
bracket.
• Turn the adjustment knob (Figure G3) counter-clockwise
to loosen the bracket arm.
• Slide the bracket arm up or down to the desired height
(Figure G4). To change the bracket from 90°to 180°,
slide the bracket arm to the top of the bracket and then flip
the arm to the right (Figure G5).
• Turn the adjustment knob (Figure G3) clockwise to lock
the bracket arm in place.
3. Use the bracket’s clamp (Figure G6) to hold the laser in
place on a stud, ceiling grid, or pole.
• If necessary, rotate the clamp so it is positioned at the
correct angle for attaching to the object. While holding the
bracket arm with one hand, use your other hand to turn
the clamp (Figure G7).
• Position the bracket’s clamp around the stud, ceiling
grid, or pole.
• Turn the clamp knob (Figure G8) clockwise until the
clamp is tight around the object and the bracket is held
in place.
Using the Laser with Other Accessories
WARNING:
Since accessories other than those offered by
STANLEY have not been tested with this laser, use of
such accessories with this laser could be hazardous.
Only use STANLEY®accessories that are recommended for use
with this model. Accessories that may be suitable for one laser
may create a risk of injury when used with another laser.
The laser is equipped with a 1/4-20 female thread on the
bottom, side, and back (Figure C) to accommodate current or
future STANLEY®accessories.
• Only use STANLEY® accessories specied for use with this
laser and carefully follow the directions included with the
accessory.
Other recommended accessories for use with this laser are
available at extra cost from your local dealer or authorized
service center. If you need assistance locating any accessory,
please contact your nearest STANLEY service center or visit our
website: http://www.STANLEY.com.
Maintenance
• When the laser is not in use, clean the exterior parts with a
damp cloth, wipe the laser with a soft dry cloth to make sure it
is dry, and then store the laser in the kit box provided.
• Although the laser exterior is solvent resistant, NEVER use
solvents to clean the laser.
• Do not store the laser at temperatures below -5 ˚F (-20 ˚C) or
above 140 ˚F (60 ˚C).
• To maintain the accuracy of your work, check the laser often

E
14
to make sure it is properly calibrated.
• Calibration checks and other maintenance repairs may be
performed by STANLEY service centers.
Troubleshooting
The Laser Does Not Turn On
• Check the AA batteries to make sure:
• Each battery is installed correctly, according to (+) and (–)
listed inside the battery compartment.
• The battery contacts are clean and free of rust or corrosion.
• The batteries are new, high-quality, name brand batteries
to reduce the chance of battery leakage.
• Make sure the AA batteries are in proper working condition. If
in doubt, try installing new batteries.
• When using rechargeable batteries, make sure the batteries
are fully charged.
• Be sure to keep the laser dry.
• If the laser unit is heated above 120 ˚F (50 ˚C), the unit will
not turn ON. If the laser has been stored in extremely hot
temperatures, allow it to cool. The laser level will not be
damaged by using the Power/Transport Lock switch before
cooling to its proper operating temperature.
The Laser Beams Flash
When in self-leveling mode, the lasers are designed to self-
level up to an average of 4° in all directions. If the laser is tilted
so much that the internal mechanism cannot level itself (or the
laser is not level when in manual mode), the laser beams will
ash indicating that the tilt range has been exceeded.
THE FLASHING BEAMS CREATED BY THE LASER ARE
NOT LEVEL OR PLUMB AND SHOULD NOT BE USED
FOR DETERMINING OR MARKING LEVEL OR PLUMB. Try
repositioning the laser on a more level surface.
The Laser Beams Will Not Stop Moving
The laser is a precision instrument. Therefore, if it is not
positioned on a stable (and motionless) surface, the laser will
continue to try to nd level. If the beam will not stop moving, try
placing the laser on a more stable surface. Also, try to make
sure that the surface is relatively at and level, so that the laser
is stable.
Service and Repairs
Note: Disassembling the laser level will void all warranties on
the product.
To assure product SAFETY and RELIABILITY, repairs,
maintenance and adjustment should be performed by
authorized service centers. Service or maintenance performed
by unqualied personnel may result in a risk of injury. To locate

레이저 사용
작동 팁
• 항상 레이저 빔의 중심을 표시하십시오.
• 극한의 기온 변화는 정확도에 영향을 줄수있는 내부
부품의 움직임을 야기할 수있습니다. 작업하는 동안 종
종정확도를 확인하십시오.
• 레이저를 떨어뜨렸던 적이 있는 경우, 레이저가 그대로
보정되어 있는지 확인하십시오.
• 레이저가 제대로 교정되어 있으면 레이저는 자체적으
로수평을 유지합니다. 각레이저는 평균 ± 4°의수평 내
의평평한 표면에 위치하는 한수평을 유지하도록 공장
에서 조정되어 있습니다. 수동으로 조정할 필요가 없습
니다.
• 매끄럽고, 평평하며 반반한 표면 위에서 레이저를 사용
하십시오.
레이저 끄기
레이저를 사용하지 않을 때는 전원/운반 잠금 스위치를
OFF 위치(그림 A 2 )로밀어 놓습니다. 스위치가 OFF 위
치에 있지 않을 경우 레이저가 꺼지지 않습니다.
레이저에 브라켓 사용하기
레이저를 스터드, 천장 그리드 또는 봉에 쉽게 장착할 수
있도록 브라켓(그림 G )이레이저에 포함되어 있습니다.
1. 레이저를 브라켓에 안전하게 장착합니다.
• 레이저의 하단, 측면 또는 뒤쪽에 있는 1/4-20 스레
드를 사용해서(그림 C ), 브라켓 암의 1/4-20 스레드
에레이저를 놓습니다(그림 G 1 ).
• 레이저 노브(그림 G 2 )를시계 방향으로 돌려서
레이저를 브라켓 암의 1/4-20 스레드에 잠급니다.
2. 필요할 경우, 브라켓에서 레이저의 높이나 위치를 변
경합니다.
• 조정 노브(그림 G 3 )를시계 방향으로 돌려서 브
라켓 암을 풉니다.
• 브라켓 암을 위또는 아래로 밀어서 원하는 높이에
맞춥니다(그림 G 4 ). 브라켓을 90°에서 180°로변
경하려면, 브라켓 암을 브라켓의 위쪽으로 민다음
암을 오른쪽으로 획젖힙니다(그림 G 5 ).
• 조정 노브(그림 G 3 )를시계 방향으로 돌려서 브
라켓 암을 제자리에 잠급니다.
3. 브라켓의 클램프(그림 G 6 )를사용하여 레이저를
스터드, 천장 그리드 또는 봉의 제자리에 고정합니다.
• 필요할 경우 물체를 장착할 수있는 정확한 각도에
위치하도록 클램프를 돌립니다. 브라켓 암을 한손
으로 잡고 있는 동안, 다른 손을 사용해서 클램프를
돌립니다(그림 G 7 ).
• 브라켓의 클램프를 스터드, 천장 그리드 또는 봉주
위에 놓습니다.
• 클램프가 물체 주위로 꽉끼고 브라켓이 제자리에
잡힐 때까지 클램프 노브를 시계 방향(그림 G 8 )
으로 돌립니다.
레이저에 기타 액세서리 사용하기
경고: 알맞지 않은 액세서리를 이레이저와 함께
사용하면 위험할 수있습니다.
이 모델과 함께 사용하도록 권장되는 STANLEY® 액세서
리만 사용하십시오. 한 가지 레이저에 적합한 액세서리
를 다른 레이저와 함께 사용하면 부상을 입을 수 있습니
다.
현재 또는 미래의 STANLEY® 액세서리를 위한 충분한 공간
을제공하기 위해 레이저에는 하단, 측면 및뒤쪽(그림 C)
에1/4-20 암스레드가 설치되어 있습니다.
• 이레이저와 함께 사용하도록 지정된 STANLEY®액세서
리만 사용하고 액세서리에 포함되어 있는 지시 사항을
따르십시오.
본레이저와 함께 사용을 권장하는 기타 액세서리는
해당 지역에 있는 판매점이나 공인 서비스 센터를 통해

면, 가까운 STANLEY 서비스 센터에 문의하거나 웹사이트:
http://www.STANLEYTOOLS.co.kr를방문하십시오.
유지 보수
• 레이저를 사용하지 않을 때는, 젖은 헝겊으로 외부 부품
을청소하고 부드러운 마른 헝겊으로 레이저를 닦아 확
실히 건조시킨 다음 제공된 키트 박스에 레이저를 보관
하십시오.
• 레이저 외관이 용제에 강하더라도 레이저를 청소하는
데절대 사용하지 마십시오.
• -20 ˚C (-5 ˚F) 미만 또는 60 ˚C (140 ˚F) 이상의 온도에서 레
이저를 보관하지 마십시오.
• 작업의 정확성을 유지하려면, 종종 레이저를 점검해 적
절히 보정되었는지 확인하십시오.
