Johnson 9100 User manual

ABOUT THIS PRODUCT
This leveling instrument uses a laser beam to plot distant points or lines.
The sleeve, or main body, of this spirit level is made of heavy-duty aluminum
and contains two level vials (horizontal and adjustable) as well as a
semi-conductor laser.
When installed on the leveling base and rotated 360-degrees, the laser
point (beam) of this level will always project at a constant horizontal. The
lightweight, yet sturdy, tripod quickly sets the laser point at the required
height. The laser point attachments included in the kit help find level and
plumb points easily. These attachments can be adjusted to any angle.
This level may be used both indoors and out. It is suitable for contractors
and DIY’ers alike.
ACCESSORIES INCLUDED
• 360-degree rotating leveling base
• Telescoping tripod
• 90-degree angle deviator (splitter) lens
• Line projection (spreader) lens
• Tinted goggles
• 2 AAA (1.5V) batteries
ATTENTION! ATTENTION!
• Never look into the laser beam without certified eye protection.
Improper use of this laser level may cause injury to the eyes.
• Do not direct laser beam at another person or reflective surfaces.
Even a lower capacity laser beam may cause injury to the eyes.
• Store laser level out of children’s reach. It is not a toy.
• Any change to the laser level resulting in increased performance is
strictly prohibted. Any claim for damages due to injuries resulting
from the non-compliance of these safety instructions will be refused.
• When storing laser level for time periods over 3 months, remove the
batteries from the unit in order to avoid damage due to battery leaks.
• This laser level does not contain any serviceable parts. Never open
the housing, as this will void the warranty.

ASSEMBLY & OPERATING MANUAL

INSERTING/CHANGING BATTERIES
& ACTIVATING THE LASER BEAM
Open the red, threaded connector
and insert the two AAA (1.5V) batteries
as shown on the diagram printed on
the level sleeve.
To turn the laser level “on”, rotate the
knob located above the laser beam
exit hole in a clockwise direction.
To turn the beam “off”, rotate the
knob counter-clockwise.
Note: Used (discharged) batteries
are hazardous waste and must be
disposed of properly.
ASSEMBLY & ADJUSTMENT
Expand the legs of the tripod and position it firmly on an
even, near-level surface. On uneven surfaces and inclines,
compensate by adjusting the telescoping legs of the tripod
and find level with the aid of the built-in Bull’s Eye™ centering
vial (found at the top of the tripod’s base).
Tightly screw the rotating leveling base and tripod together.
Bring the leveling plate of the base into a level position
by means of the three adjusting screws and the built-in
Bull’s Eye™ centering vial.
Place the spirit level on the leveling plate and tighten
it with the locking clamp. Check to ensure the vial registers level.
Use the regulating screws to adjust. (Center the bubble exactly
between the markings on the vial).
Loosen the “stop” screw, rotate the level 90 degrees and check for level
again using one of the other adjusting screw(s)--if necessary. Return to
original position and re-check, re-adjusting if required.
The elevation of the laser point can be fixed to the desired position
using the tripod’s handle crank. Use the degree scale on the leveling
base to set the level at the required angle.

90° ANGLE/
BEAM SPLITTING OPTION
By inserting the splitter lens into the laser beam
exit hole, the emerging laser beam is split by
90 degrees. This generates a vertical (perpen-
dicular) reference line to the standard, horizon-
tal laser beam.
LINE PROJECTION
By mounting the line projector attachment, a
line will be projected onto the wall (instead of a
point). In order to achieve the most accurate
line, mark two points with the help of the point
beam. Mount the line projector attachment and
connect these points with the projected line.
Please note: Use of the line projection lens
results in a loss of brightness.
WARNING!
DO NOT LOOK DIRECTLY INTO THE LIGHT BEAM.
DO NOT AIM LIGHT BEAM DIRECTLY INTO EYES.
THIS WILL DAMAGE THE EYES.
