Read all instructions. Failure to

follow all instructions listed below may result in hazardous radiation exposure, electric shock, fire and/or serious injury. The term “tool” in all of

the warnings listed below refers to your mains-operated (corded) tool or battery-operated (cordless) tool.

The following labels are on your tool

for your convenience and safety. They indicate where the laser light is emitted by the tool. ALWAYS BE AWARE of their location when using the tool.

Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself. This tool produces laser class 2M laser radiation and complies with 21 CFR

1040.10 and 1040.11 except for deviations pursuant to Laser Notice No. 50, dated June

24, 2007. This can lead to persons being blinded.

Changes or modifications to this equipment not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

DO NOT remove or deface any warning or caution labels. Removing labels increases the risk of exposure to laser radiation.

Use of controls or adjustments or performance of procedures other than those specified in this manual, may result in hazardous radiation exposure.

General Safety Rules

WARNING

ALWAYS make sure that any bystanders in the vicinity of use are made aware of the dangers of looking directly into the laser tool.

DO NOT place the laser tool in a position that may cause anyone to stare into the laser beam intentionally or unintentionally. Serious eye injury could result.

ALWAYS position the laser tool securely. Damage to the laser tool and/or serious injury to the user could result if the laser tool fails.

ALWAYS use only the accessories that are recommended by the manufacturer of your laser tool. Use of accessories that have been designed for use with other laser tools could result in serious injury.

DO NOT use this laser tool for any purpose other than those outlined in this manual. This could result in serious injury.

DO NOT leave the laser tool “ON” unattended in any operating mode.

DO NOT disassemble the laser tool. There are no user serviceable parts inside. Do not modify the product in any way. Modifying the laser tool may result in hazardous laser radiation exposure.

DO NOT use the laser viewing glasses as safety goggles. The laser viewing glasses are used for improved visualization of the laser beam, but they do not protect against laser radiation.

DO NOT use the laser viewing glasses as sun glasses or in traffic. The laser viewing glasses do not afford complete UV protection and reduce color perception.

DO NOT use any optical tools such as, but not limited to, telescopes or transits to view the laser beam. Serious eye injury could result.

DO NOT stare directly at the laser beam or project the laser beam directly into the eyes of others. Serious eye injury could result.

Work area safety

Keep work area clean and well lit. Cluttered or dark

areas invite accidents.

DO NOT operate the laser tool around children or allow children to operate the laser tool. Serious eye injury could result.

Electrical safety

Batteries can explode or leak, cause

injury or fire. To reduce this risk,

always follow all instructions and warnings on the battery label and package. DO NOT short any battery terminals. DO NOT charge alkaline batteries. DO NOT mix old and new batteries. Replace all of them at the same time with new batteries of the same brand and type. DO NOT mix battery chemistries. Dispose of or recycle batteries per local code. DO NOT dispose of batteries in fire. Keep batteries out of reach of children. Remove batteries if the device will not be used for several months.

Personal safety

Stay alert, watch what you are doing and use common sense when operating a tool. Do not use a tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention

while operating a tool may result in serious personal injury or incorrect measurement results.

Use safety equipment. Always wear eye protection.

Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

WARNING

Use and care

Use the correct tool for your application. The correct

tool will do the job better and safer.

Do not use the tool if the switch does not turn it on and off. Any tool that cannot be controlled with the

switch is dangerous and must be repaired.

Store idle tool out of the reach of children and do not allow persons unfamiliar with the tool or these instructions to operate the tool. Tools are dangerous in

the hands of untrained users.

Maintain tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the operation. If damaged, tool repaired before use. Many accidents are caused by

poorly maintained tools.

Use the tool, accessories, etc., in accordance with these instructions and in the manner intended for the particular type of tool, taking into account the working conditions and the work to be performed.

Use of the tool for operations different from those intended could result in a hazardous situation.

Service

Have your tool serviced by a qualified repair person using only identical replacement parts. This will

ensure that the safety of the tool is maintained.

Develop a periodic maintenance schedule for tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or may be improperly mounted.

Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.

Inserting/Replacing the Battery

Open the battery cover by releasing the battery door clip on the bottom of the housing. If replacing batteries, remove the existing batteries. Insert three “AA” batteries into the tool. Be sure to check for battery polarity, as indicated inside the battery housing.

Note: Refer to Electrical Safety Procedures prior to replacing the batteries.

Alkaline batteries offer the longest battery life when used in this tool.

Note: Extreme temperatures and the use of batteries

with different levels of charge can reduce the operating time of the tool. Always use batteries with the same power rating and from the same manufacturer. For the proper disposal of the used batteries, see the section “Environmental Protection”.

• Remove the batteries from the tool when not using

it for extended periods. When storing for extended

periods, the batteries can corrode and discharge themselves.

Technical Data

Initial Operation

• Protect the tool against moisture and direct sun

irradiation.

• Do not subject the tool to extreme temperatures or

variations in temperature.

For an example, do not leave it in a vehicle for long periods. In case of large variations in temperature, allow the tool to adjust to the ambient temperature before putting it into operation. In case of extreme temperatures or variations in temperature, the accuracy of the tool can be impaired.

• Avoid heavy impact or dropping of the tool. After

heavy exterior impact on the tool, an accuracy check should always be carried out before continuing to work.

Working Advice Horizontal Applications (Fig. 2)

Set the unit on a flat surface. Use the T-Edge to square unit to any surface with a 90° reference for aligning or plumbing.

Vertical Applications

To attach to vertical surface, apply a small portion of adhesive putty to push pads (Fig.3). Align instrument using horizontal leveling vials. Firmly press push buttons to attach unit to surface. (Fig. 4).
