Differences in the Lasers
The differences in the four laser models discussed in this manual are as follows:
•
Accuracy: the L-743 and L-742 are four times more accurate for flatness and two times more
accurate for squareness than the L-733 and L-732. The L-733 and L-732 have a pitch/roll/yaw base
with medium adjustments and the L-743 and L-742 have a pitch/roll/yaw base with both coarse and
fine adjustments (see Figure 1).
•
Number of laser planes: the L-743 and the L-733 have three laser planes and the L-742 and L-732
have two laser planes that can be factory-configured for two vertical planes (wall/wall) or one vertical
and one horizontal plane (wall/ceiling).
When drawings are used to describe a procedure, the laser model will be identified in the caption.
However, the procedures themselves are essentially the same for all four lasers. Appendix A, beginning
on Page 24, provides detailed drawings and specifications for each laser model.
