WORKINGWITH OBSTRUCTIONS AND USER INTERFERENCE

(See Figures 8 and 9)

Figure 8 illustrates the nature of the laser line projected from the Laser Trac TM

Level° It is actually a "plane" of laser light. This is important because
obstructions and user interference that takes place in front of the device
WILL NOT affect the laser line projected on either side of the user or obstruction.

Figure 9 illustrates the ability of the Laser Trac TM Level to provide a straight and
level line on either side of a large obstruction, such as a hot water heater.

REFERENCING AND LEVELING ACROSS MULTIPLE ADJACENT
SURFACES (See Figures 10 and 11)

The Laser Trac TM Level's plane of light is also useful when working with two or

more adjacent surfaces_
Figure t0 illustrates its use in aligning electrical boxes on stud work with two

adjoining walls,,

Figure 11 illustrates pictures being aligned on multiple room walls.

USING THE LASER TRAC TM LEVEL

This level can be easily and conveniently used in several ways, it can be
hand-held, wall-mounted with the pin base or placed in the precision leveling

base_ Also use tripod base (included) to mount level to a tripod (not included)_

USING AS A HAND-HELD LEVEL (See Figures 12 and 13)

This level can be held in one hand for use as a straight line reference tool

(as shown in Fig. 12).
It can be easily adjusted with the finger or thumb 90 ° from a horizontal to

vertical line and all angles in between.

As a hand-held device the Laser Trac TM
Level can be used for quick reference

and alignment across any two points of
reference such as lining up cut-outs
and fixtures on drywall or checking wall
paper and paint trim. Also ideal for
insuring straight placement of mounted
fixtures and brackets, such as stair
railing fittings (as shown in Fig. 13).
