The following describes the operational features of the L-708 Laser, shown 

in Figure 1.  

 

 

The power switch 

has a lighted LED to indicate that power is ON.  

 

The  battery  pack connector 

accepts a slip-fit probe with a flexible 

cord.  

 

The bubble level vial 

on  the laser mounting flange is  used for 

rotational accuracy. When the bubble  in the level vial is  centered 

horizontally, all adjustments controlling laser beam angle will shift the 

laser beam vertically or horizontally with reference to the bore/target 

axis. If the bubble is 

not 

centered, any adjustment to one laser axis will 

change the laser beam position in both axes. The levels also provide 

fixture mounting repeatability.  

 

Precision Angular Adjustment Knobs 

provide angular pointing control for the laser beam so it can 

be tilted with a resolution of .0007 in. in 100 ft. (0.018mm in 30.5 m). The L-708LD laser has an 

angular adjustment resolution of .0014  in.  in 200 feet 

(0.036 mm in 61 m).  

 

The  Center of Adjustment Range Indicator for 

Coarse Adjustments

 is a small window containing 

a white dot. The white dot follows the coarse 

angular adjustment of both axes.   If the white dot 

displays  in the center of the window, both the 

Horizontal and Vertical angular adjustments  are 

centered. 

 

The Fine Adjust Tool Bar 

swivels to indicate the 

middle of the adjustment range of the fine 

adjustment knobs.  Rotate the bar (located under the 

Vertical and Horizontal Fine Adjust knobs)  and 

tighten  the knobs until they nearly touch the tool 

bar. Rotate the bar away from the knobs and the 

knobs are now in the middle of the adjustment 

range.

Starting an Alignment with the L-708 

To start the alignment, it is important to make sure the L-708’s angular adjustments are in the center of 

their adjustment range.  There are two indicators to aid in setting the adjustments in the center of their 

range: 

 

1.

 

Coarse Angular Adjustment 

 

Indicator

 – a white dot in a round window 

that indicates how far off center the coarse 

angular adjustments are.  To start an 

alignment, ensure the white dot is centered 

in the window using the 

coarse

 angular 

adjustments.
