-11- 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 a...

-12- DO NOT use any optical tools such as, but not limited to, tele-scopes or transits to view the laser beam. Serious eye injury could result. 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, alco...

-13- 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 condi...

-16- Preparation Inserting/Replacing the Battery Alkali-manganese batteries are recommended for the measuring tool.– Fold open the battery lid 7 and insert the batteries. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery compartment.If...

-17- Initial Operation Protect the measuring tool against moisture and direct sun exposure. Do not subject the measuring tool to extreme temperatures or variations in temperature. For example, do not leave it in vehicles for a long time. In case of large variations in temperature, allow the measurin...

-19- Deactivating the Automatic Shut-off: – To deactivate automatic shut-off, hold down button 6 for at least 3 s with the measuring tool switched on. When automatic shut-off is deactivated, the laser lines will flash briefly as confirmation. Note: When the operating temperature exceeds 113° F (+ 45° C...

-20- If the measuring tool is outside of the self-leveling range, the laser lines will flash quickly. If during work with automatic leveling you switch to the “working with-out automatic leveling” mode (On/Off switch 2 in position “ ”), the first combination of this mode’s lines is always activated. W...

-22- In addition to external influences, device-specific influences (e.g. falls or heavy impacts) can also lead to deviations. For this reason, check the leveling accuracy each time before beginning work.First, check both the height as well as the leveling accuracy of the hori-zontal laser line, then t...

-24- d 180° A B – The difference d of both marked points I and III on wall A indicates the actual height deviation of the measuring tool. The maximum permitted deviation dmax can be calculated as follows:dmax = double the distance between the walls x 0.0118 in (0.3 mm)Example: If the distance betwee...

-26- d 2,5 m A B 8 ft (2.5 m) 16 ft (5 m) – The difference d of both marked points I and III on wall A indicates the actual deviation of the measuring tool from the level plane. The maximum permitted deviation dmax can be calculated as follows:dmax = double the distance between the walls x 0.0118 in...

-28- 7 ft (2 m) d – The difference d between point III and the center of the laser line at the upper edge of the door opening results in the actual deviation of the measuring tool from the vertical plane. – Measure the height of the door opening. The maximum permitted deviation dmax is calculated as...
