Use with Accessories Working with Wall Mount (Optional Accessory) The durable metal wall mount provides a flexible, yet sturdy means of positioning the tool in the desired location. 1. Determine the approximate height at which the laser beam will need to be project. To ensure the ability to adjust the tool height either up or down to the intended laser line, the top of the mount should be positioned so that the slot on the back side of the mount is even with intended laser line. 2. Choose the surface on which the mount will be attached, wall, T-bar framing or beam. 3. Secure the mount to the mounting surface When mounting to a wall, drive two or three study screws into the wall with at least one driven into a stud. Make sure the screw heads are wide than the upper end of the screw openings. When mounting to a T-bar framing or beam, slide the slot on the back side of the mount over the frame and tighten the two knurled knobs. Make sure that full surface of the bolt ends press against the T-bar framing or beam. 4. Securely attach the tool to the mount using the 5/8-11 knurled knob on the underside of the platform. 5. Adjust the height of the tool over an 8" / 20 mm vertical extension range using the inch or metric scale on the side of the bar and using the height locking knob. Working with Tripod (Optional Accessory) A tripod 26 offers a stable, height-adjustable measuring support. Place the tool via the tripod mount 7 onto the 5/8-11 male thread of the tripod and screw the locking screw of the tripod tight. Working with the Measuring Plate (Optional Accessory) With the measuring plate 23, it is possible to project the laser mark onto the floor or the laser height onto a wall. The red acrylic used in the target enhances the laser beam, making the laser dot more visible. With the zero field and the scale, the offset or drop to the required height can be measured and projected at another location. This eliminates the necessity of precisely adjusting the tool to the height to be projected. The measuring plate 23 has a reflective coating that enhances the visibility of the laser beam at greater distances or in intense sunlight. The brightness intensification can be seen only when viewing, parallel to the laser beam, onto the measuring plate Laser Viewing Glasses (Optional Accessory) The laser viewing glasses filter out the ambient light. This makes the red light of the laser appear brighter for the eyes. The red plastic used in the glasses enhances the laser beam, making the laser dot more visible. These glasses are particularly useful when using the GRL145HV laser tools outdoors or in brightly lit environments. • 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. -14-
