Battery Safety
The FMHT77617 laser is powered by a Li-ion battery.

WARNING:
To reduce the risk of injury, the user must read the product User Manual, Laser Safety Manual, and the Battery Safety Manual.

Charging the Battery

Use the charging unit that is packaged with the FMHT77617 laser to charge the laser’s Li-ion battery.

1. Insert the electrical plug at one end of the charging unit into an electrical outlet (Figure B 1 ).
2. On the back of the laser, pull the port cover off and to the side (Figure B 2 ).
3. Insert the small end of the charging unit into the laser’s charging port (Figure B 3 ).
4. Allow the battery time to charge fully. The Power LED will remain on while the battery is charging.
5. After the Power LED turns off, disconnect the charging unit from the electrical outlet and the laser’s charging port.
6. Push the port cover back over the laser’s charging port.

Whenever the laser is not in use, slide the Power/Transport Lock switch to the LEFT to the Locked/OFF position (Figure A\ 1 ) to save battery power.

Using the Mounting Block

On the bottom of the laser is a moveable block (Figure D ).

• To use the magnets on the front of the laser (Figure A 8 ) to mount the laser against the side of a steel beam, do not extend the moveable block (Figure D 1 ). This will allow the down dot to be aligned with the edge of the steel beam.
• To mount the laser over a point on the floor (using a multifunction bracket or a tripod), pull out the moveable block until it clicks in place (Figure D 2 ). This will allow the laser down dot to display through the 5/8-11 mounting hole and the laser to be rotated over the 5/8-11 mounting hole without moving the vertical position of the laser.

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. Slide the Power/Transport Lock switch to the right to the Unlocked/ON position (Figure A 2 ).
3. Press (Figure A 6 ) once to display a horizontal laser line, a second time to display a down dot, and a third time to display a horizontal line and a down dot.
4. Check the laser beams. The laser is designed to self-level.
   • If the laser is tilted so much that it cannot self-level (> 4°), the laser beams will continually flash twice and (Figure A 4 ) will flash constantly on the keypad.
   • If the laser beams flash, 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.
5. Press (Figure A 5 ) once to display a vertical laser line from the front of the laser, a second time to display a vertical laser line from the side of the laser, and a third time to display both vertical lines.
6. Press (Figure A 7 ) to test the Pulse mode. will illuminate, and the laser beams will appear lighter since they are flashing at a very rapid rate. You will only use Pulse mode with a detector to display the laser beams long range.
7. 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 first 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, flat, 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 9m (30′) 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 laser against the end of a 9m (30′) wall (Figure E 1 ).
2. Turn the laser ON.
3. Press once to display a horizontal laser beam.
4. Turn the laser toward the opposite end of the wall and parallel to the adjacent wall.
5. At least 9m (30′) apart on the laser beam, mark a GB and b .
6. Turn the laser 180º.
7. Adjust the height of the laser so the center of the beam is aligned with a (Figure E 2 ).
8. Directly above or below b , mark c along the laser beam (Figure E 3 ).
9. Measure the vertical distance between b and c .
10. If your measurement is greater than the Allowable Distance Between b and c for the corresponding Distance Between Walls in the following table, the laser must be serviced at an authorized service center

Distance Between Walls	Allowable Distance Between b and c
9m (30′)	6mm (1/4”)
12m (40′)	8mm (5/16”)
15m (50′)	10mm (13/32”)

Horizontal Beam – Pitch Direction

Checking the horizontal pitch calibration of the laser requires a single wall at least 9m (30′) long. 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 laser against the end of a 9m (30′) wall (Figure F 1 ).
2. Turn the laser ON.
3. Press once to display a horizontal laser beam.

7. Position the laser toward the first end of the same wall and parallel to the adjacent wall.
8. Adjust the height of the laser so the center of the beam is aligned with b .
9. Directly above or below a , mark c along the laser beam (Figure F 3 ).
10. Measure the distance between a and c .
11. If your measurement is greater than the Allowable Distance Between a and c for the corresponding Distance Between Walls in the following table, the laser must be serviced at an authorized service center.

Distance Between Walls	Allowable Distance Between a and c
9m (30′)	6mm (1/4”)
12m (40′)	8mm (5/16”)
15m (50′)	10mm (13/32”)

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 9m (30′), with one person on the floor 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. Place the laser on a smooth, flat, stable surface that is level in both directions (Figure G 1 ).
2. Turn the laser ON.
3. Press three times to display the front and side vertical beams.
4. Press twice to display the down dot.
5. On the level surface, mark the position of the down dot a (Figure G 2 ).
6. On the ceiling, mark two short lines, b and c, where the front and side laser beams cross.
7. Pick up and rotate the laser 180º, and position the down dot directly over a the previous position of the down dot, as shown in Figure G 3.
8. On the ceiling, look at the position of the two laser beams. If they are not parallel to marked lines b and c, turn the laser until the laser beams are closely lined up with b and c .
9. On the ceiling, mark two short lines, d and e, where the beams cross.
10. Measure the distance between marked lines b and d and marked lines c and e.
11. If your measurement is greater than the Allowable Distance Between Marked Lines for the corresponding Ceiling Height in 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-levelling. Each laser is calibrated at the factory to find level as long as it is positioned on a flat surface within an average ± 4° of level. No manual adjustments are required.
• Use the laser on a smooth, flat, level surface.

Turning the Laser Off

Slide the Power/Transport Lock switch to the OFF/Locked position (Figure A 1 ) when the laser is not in use. If the switch is not placed in the Locked position, the laser will not turn off.
Using the Laser with 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 GB with this model. Accessories that may be suitable for one laser may create a risk of injury when used with another laser. The bottom of the laser is equipped with 1/4-20 and 5/8-11 female threads (Figure C ) to accommodate current or future Stanley accessories. Only use Stanley accessories specified for use with this laser. Follow the directions included with the accessory. 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:

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 -20 ˚C (-5 ˚F) or above 60 ˚C (140 ˚F).
• To maintain the accuracy of your work, check the laser often 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

• Make sure the laser’s Li-ion battery is fully charged.
• Be sure to keep the laser dry.
• If the laser unit is heated above 50 ˚C (120 ˚F), 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

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, the laser beams will flash, 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 find 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 flat 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 unqualified personnel may result in a risk of injury. To locate your nearest Stanley service center, go to  http://www.2helpU.com
