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.

This document describes a Laser Level Kit, Model #9100/40-0909, which is a leveling instrument designed to project distant points or lines using a laser beam. It is suitable for both contractors and DIY users.

Function Description

The primary function of this device is to establish a constant horizontal laser point or line. The main body of the spirit level, made of heavy-duty aluminum, houses two level vials (one horizontal and one adjustable) and a semiconductor laser. When mounted on its leveling base and rotated 360 degrees, the laser consistently projects a horizontal beam. The kit includes a lightweight, sturdy tripod that allows the user to quickly set the laser point at the desired height. Additionally, several attachments are provided to assist in easily finding level and plumb points, and these attachments can be adjusted to various angles.

Usage Features

The kit comes with several accessories to enhance its versatility:

• 360-degree rotating leveling base: This base allows the laser to be rotated fully, ensuring a continuous horizontal projection around a room or worksite.
• Telescoping tripod: The tripod's legs can be expanded and adjusted to position the laser firmly on various surfaces, even uneven ones. It includes a built-in Bull's Eye™ centering vial at the top of its base to aid in achieving a level setup. The tripod also features a handle crank for fixing the laser's elevation to the desired position and a degree scale on the leveling base for setting the level at a required angle.
• 90-degree angle deviator (splitter) lens: By inserting this lens into the laser beam exit hole, the emerging laser beam is split by 90 degrees, creating a vertical (perpendicular) reference line in addition to the standard horizontal laser beam. This is useful for tasks requiring precise right angles.
• Line projection (spreader) lens: This attachment allows the device to project a line onto a wall instead of just a point. To achieve the most accurate line, users are advised to mark two points with the point beam first, then mount the line projector attachment and connect these points with the projected line. It is noted that using this lens may result in a loss of brightness.
• Tinted goggles: These are provided for eye protection when working with the laser.
• 2 AAA (1.5V) batteries: The device operates on these batteries.

Assembly and Adjustment:

1. Battery Installation: To insert or change batteries, the red, threaded connector on the level sleeve must be opened. Two AAA (1.5V) batteries are then inserted as indicated by the diagram on the sleeve.
2. Powering On/Off: The laser level is turned "on" by rotating the knob located above the laser beam exit hole in a clockwise direction. To turn it "off," the knob is rotated counter-clockwise.
3. Tripod Setup: Expand the tripod legs and position it firmly. On uneven surfaces, adjust the telescoping legs and use the built-in Bull's Eye™ centering vial on the tripod's base to achieve a near-level setup.
4. Mounting the Leveling Base: Tightly screw the rotating leveling base onto the tripod.
5. Leveling the Base: Bring the leveling plate of the base to a level position using its three adjusting screws and the built-in Bull's Eye™ centering vial.
6. Mounting the Spirit Level: Place the spirit level on the leveling plate and tighten it with the locking clamp.
7. Fine Leveling: Check the vial to ensure it registers level. Use the regulating screws to adjust the bubble to be exactly between the markings on the vial. For further accuracy, loosen the "stop" screw, rotate the level 90 degrees, and re-check for level using other adjusting screws if necessary. Then, return it to its original position and re-check, re-adjusting as required.
8. Elevation and Angle Adjustment: The tripod's handle crank allows the user to fix the laser point's elevation. The degree scale on the leveling base can be used to set the level at a specific angle.

Maintenance Features

The manual provides specific instructions for maintenance and care:

• Battery Storage: If the laser level is to be stored for periods longer than 3 months, the batteries should be removed from the unit. This prevents potential damage from battery leaks.
• No User-Serviceable Parts: The laser level does not contain any parts that can be serviced by the user. Opening the housing will void the warranty.

Safety Information

Several critical safety warnings are highlighted:

• Eye Protection: Users must never look directly into the laser beam without certified eye protection. Improper use can cause eye injury.
• Beam Direction: The laser beam should not be directed at another person or at reflective surfaces, as even a lower capacity laser beam can cause eye injury.
• Child Safety: The laser level should be stored out of children's reach, as it is not a toy.
• Unauthorized Modifications: Any changes to the laser level that result in increased performance are strictly prohibited. Claims for damages due to injuries resulting from non-compliance with these safety instructions, unauthorized manipulation, or negligence will be refused.
• Battery Disposal: Used (discharged) batteries are considered hazardous waste and must be disposed of properly.
