HAMAR LASER L-708, Operation Manual

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.
