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
!
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

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).
