FCC Statement

Changes or modiﬁcations to this unit not

expressly approved by the party responsible for

compliance could void the user’s authority to operate the

equipment.

Note: This product has been tested and found to comply with the

limits for a Class B Digital device, pursuant to Part 15 of the FCC

Rules. These limits are designed to provide reasonable protec-

tion against harmful interference in a residential installation.

This equipment generates, uses, and can radiate radio frequency

energy and, if not installed and used in accordance with the

instructions, may cause harmful interference to radio communica-

tions. However, there is no guarantee that interference will not

occur in a particular installation. If this equipment does cause

harmful interference to radio or television reception, which can

be determined by turning the equipment oﬀ and on, the user is

encouraged to try to correct the interference by one or more of

the following measures:

– Reorient or relocate the receiving antenna.

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 measure-

ment 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.

Keep the measuring tool away from cardiac pace-

makers. The magnet plate 7generates a ﬁeld that

can impair the function of cardiac pacemakers.

Keep the measuring tool away from magnetic data medium and

magnetically-sensitive equipment. The eﬀect of the magnet plate

7can lead to irreversible data loss.

Noise Information

The A-weighted sound pressure level of the audio signal at one

meter distance is 80 dB(A).

Do not hold the tool close to your ear!

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 oper-

ate 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 af-

fect the operation. If damaged, tool repaired before use. Many

accidents are caused by poorly maintained tools.

Intended Use

The tool is intended for detecting pulsating line lasers.

Preparation

Inserting/Replacing the Battery

Alkaline batteries are recommended for the tool.

Pull the latch 16 of battery lid outward and open the battery lid 15.

When inserting batteries, pay attention to the correct polarity.

When the battery low indicator aappears for the ﬁrst time on the

display 6, the measuring tool can still be operated for approx. 2 h.

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.

Use the tool, accessories, etc., in accordance with these in-

structions 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 clean-

ing 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.

1) The working range can be decreased by unfavorable environmental

conditions (e.g. direct sun exposure).

2) The angular accuracy between the 45° laser line and the 90° laser line is

max. ±5/32 @ 30 ft (+/-0.4 mm/m).

3) Conductive pollution occurs, or dry, non-conductive pollution occurs

which becomes conductive due to condensation which is expected. In such

conditions, equipment is normally protected against exposure to direct

sunlight, precipitation, and full wind pressure, but neither temperature nor

humidity is controlled.

Please observe the article number on the type plate of your tool.

The trade names of the individual tools may vary.

Operation

Initial Operation

tProtect the tool against moisture.

tDo not subject the tool to extreme temperatures or variations

in temperature. As an example, do not leave it in vehicles for

longer 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.

DO NOT stare directly at the laser beam or project

the laser beam directly into the eyes of others.

Serious eye injury could result.

Setting Up the Tool (see ﬁgure A)

Position the tool at least 17 ft (5 m) away from the cross-line

laser. Switch on the pulsating function of the cross-line laser and

select horizontal or vertical operation.

Note: Do not select cross-line operation or else faulty indications

on the height of the laser beam can occur.

Position the tool in such a manner that the laser beam can reach

the reception area 5. Align the tool in such a manner that the la-

ser beam runs horizontally through the reception area (as shown

in the ﬁgure).

Switching On and Oﬀ

tA loud audio signal sounds when switching on the tool. There-

fore, keep the tool away from your ear or other people when

switching on. The loud audio signal can cause hearing defects.

To switch on the tool, press the On/Oﬀ button 3. An audio signal

will sound and all LEDs will light up brieﬂy.

To switch oﬀ the tool, press the On/Oﬀ button 3again. All dis-

play indicators as well as all LEDs light up brieﬂy and an audio

signal sounds before the tool switches oﬀ.
