General Leveling and Aligning
1.  Place the laser on a flat surface.  The laser must be level within its self-

leveling range.

2.  Adjust the position of the lines and plumb point so they are at the desired 

positions.

3.  Mark the position of the wall, elevation, 

floor or ceiling.

Installing and Plumbing a Wall
1.  Place the laser so the Vertical Line Beam 

is positioned over the desired wall location 

(usually indicated by 2 floor marks).
Note:

 If the floor track is already installed 

the laser should be setup using the 

extendable legs so the Vertical Line can 

be positioned over the edge of the track. 

2.  Use the Vertical Line Beam to position 

the top track.

3.  Use the Vertical Line Beam to position 

the floor track.

 The batteries should be removed when storing the laser more 

than 30 days.

1.  Turn the battery door knob counterclockwise to release the battery pack.
2.  Install/remove the 4 x AA batteries.
  Note: When installing the batteries, be sure to note the positive (+) and 

negative (–) diagrams molded on the battery housing.

3.  Put the battery pack in place and lock it by turning the knob clockwise.
Battery Charger

1.  Plug the battery recharger’s plug into the 

laser’s  battery recharging jack.

2.  Plug the battery recharger into the wall 

outlet.

 A full charge will be reached in 4-5 

hours.

Thank you for choosing the Spectra Precision

®

 1.5PL from the Trimble

®

 family 

of precision products. This simple-to-use tool allows you to perform leveling 

or vertical plumb work. You can also use the laser outdoors for leveling and 

aligning applications (optional HR220 receiver required).
Before using the laser, be sure to read this operator’s manual carefully. 

Included in it is information about setting up, using, and maintaining the 

laser. Also included in this manual are CAUTIONS and Notes. Each of these 

words represents a level or danger or concern. A CAUTION indicates a hazard 

or unsafe practice that could result in minor injury or property damage. A 
Note

 indicates important information unrelated to safety.

1.  Power and Audio Button – turns the 

receiver ON and OFF and changes the 

audio to LOUD, LOW or OFF.

a.  Automatic Shutoff - If the photocell 

does not detect the laser beam for 30 

minutes, the receiver shuts off 

automatically.

2.  Marking Notches (both sides) – align 

with the on-grade portion of the 

photocell and are used to mark elevation 

readings. The marking notches are 50 

mm (2 in.) from the top of the receiver.

3.  Liquid Crystal Display (LCD) – 

displays the elevation, power, audio and 

battery status.

4. Bubble vials - aids in keeping receiver 

level in both horizontal and vertical 

planes.

5.  Photocell – detects the laser beam when 

it strikes the receiver.

6.  Audio Port – is the opening the sound 

comes out of.

7.  Clamp-Tab Recess – is the area that the 

general-purpose clamp’s release tab fits 

into.

8.  Label – shows the serial number and manufacturing date.
9.  Magnet—holds the receiver on a wall molding, cross-T, runner, etc.
10.LEDs – show the position of the receiver relative to the laser beam (above 

grade [red], on grade [green] or below grade [blue]).

11.Battery Housing – holds 2 AA alkaline batteries.
12. Battery Door Latch– opens the battery compartment.

The C61 clamp allows the receiver to be attached to a survey rod or wooden pole.
1.  Release Tab – allows the receiver to be locked onto or released from the 

general-purpose clamp.

2.  Jaws – close/open so that the general-purpose clamp can be attached to or 

released from a survey rod or wooden pole.

3.  Jaws Screw – controls the closing/

opening of the jaws.

4.  Reading Edge – aligns with the 

receiver’s on-grade marking notches.

5.  Bubble Screw Holes – are where the 

optional 1277-6251S rod bubble kit 

is mounted.

1.  Unlock the laser’s compensator by turning the 

compensator lock/ unlock knob to the LEFT. 

The Power On/Low Battery LED illuminates 

RED and the vial lights GREEN when the unit 

has been set up inside its self-leveling range. 

  When the batteries need to be charged/changed the Power On / Low 

Battery LED flashes RED.

 For added mechanism protection always lock the laser when not in use 

by turning the compensator lock/ unlock knob to the RIGHT.

Automatic Mode
1.  Turn the compensator knob to the On-Position- the Power On / Low 

Battery LED illuminates RED and the vial lights GREEN when the unit 

has been set up inside its self-leveling range. 

2.  The beams can be activated/deactivated using the buttons

Installing a Ceiling
1.  Measure up from the floor (or other reference mark) to the finished ceiling 

height.

2.  Install the first piece of wall molding.
3.  Mount the (optional) wall mount with the attached laser to the wall molding.
4.  Adjust the elevation of the wall mount slider so that the level beam is at wall 

molding height. Install the rest of the wall molding.

5.  Lower the laser 5 cm (2.0 in.) on the wall mount so that the level beam is at 

the horizontal target elevation.

6.  Install the ceiling’s cross Ts and main Ts.

Performing Layout for Angles Other than 90°
1.  Set up the unit over the 1st base-line reference point 
2.  Use the handle to make a rough alignment to the 2nd base-line reference 

point, then use the fine adjustment knobs for final alignment 

3.  Use the angle ring to set the 0-mark on the reference line 
4.  Use the handle to roughly align the unit to the required angle position 
5.  Use the fine adjustment knobs to adjust the unit until the required angle is 

positioned exactly above the reference line.
