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.

The tool is intended for the horizontal and diagonal

aligning of tiles and laminate.

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.

Features

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.

Switching On and Off

To switch on the tool, press the On/Off switch 1once

briefly. Immediately after switching on, the tool projects

the two laser lines 90° from the exit openings 2.

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).
