Instructions for use
The following procedure is best performed on a flat and
Place the Laser String on the ground with the alignment bar
approximately ½” to 1 ½” from the edge of the tire and release the
handle. The Laser String
straight edge should now be against the surface of the tire.
Using the level vial, level the Laser String tripod with
the front adjustable leg. NOTE:
The laser tripod will be at a 7-degree angle with the level vial
at level. This is normal.
Check to see if the limit pins are touching the edge of the
two-inch holes. If
touching, repeat steps 1 and 2 until limit pins clear edges.
Caution: The laser being used is a low power
laser with a light output of only a few milli-watts.
It should not be confused with powerful lasers intended for
burning, cutting, and drilling. Although
the beam is low power it should be handled with caution and common
sense. The greatest
potential for harm from lasers is to the eyes.
Just as one should not look directly into the sun or high
intensity lamps, avoid looking directly at the laser beam or staring at
the reflections from the laser mirror used in the system.
Advise other personnel in the immediate area of the use of
lasers. Keep this product
out of the reach of children.
Turn on the laser by pressing the red push button on the
switch cap. Some models may
have a rotating black rubber knob.
Take two measurements at arrows shown in illustration as
you would in a typical string setup.
Adjust rear axle until measurements are equal.
Place Laser String on opposite side of vehicle.
Take two measurements at arrows shown in illustration as you
would in a typical string setup. Measurements should be equal with those taken in the previous
step. If they are unequal
and the vehicle has a solid rear axle there is a toe condition.
For independent rear, adjust for equal measurements.
Once measurements are equal (zero rear offset) use the
Laser String to set toe angle and measure camber angle using the common
string method by measuring from the laser to your front wheel.
Additionally, by using the red laser marking on the ground, it is
possible to determine the contact patch alignment front to rear.
using laser head for fixturing, alternate methods of using the level
vial for setting laser perpendicularly to your work piece are
recommended for higher accuracy. Fro
applications of distance greater than 14 feet it is recommended that the
two foot alignment bar be calibrated to specific tolerances.
The factory calibration of the laser to alignment bar is set for
parallelism of ± .032 @ 14 feet.
