4. ACCURACY CHECK This instrument requires no calibration. The regular accuracy checks ensure that the instrument's accuracy has not been impaired by falls or heavy impacts. It is recommended to check the laser level accuracy each time before beginning workday usage. The accuracy check procedure includes three steps: the horizontal line height check (step 1) , the horizontal line leveling check (step 2) , the vertical line leveling check (step 3) . If, during one of the tests, the measured deviation exceeds the allowable deviation, repeat the test procedure. Should the readings persist over the allowable deviation, the instrument is out of calibration and must be serviced. Contact ToughBuilt ® Customer Service for additional support. It is recommended to conduct the accuracy check on a wall distance close to the distance of the applications for which the instrument will be used. The following accuracy check procedure suggests the most practical scenarios at the recommended distance. The surface of the area where the accuracy check procedure is conducted must be sufficiently level, so that the instrument remains within the self-leveling range of ± 4° from the 0° level position.
Using The QuickSet ® Multi-Position Bracket The QuickSet ® Multi-Position Bracket allows mounting the instrument onto various objects ranging in thickness between 1/4" and 2-3/8" (6mm and 60mm). The instrument mounted onto the bracket can be positioned in various orientations and project either a leveled or a tilted line. 1. To attach the bracket to the desired object, loosen the Clamping Knob 11 , mount the bracket, and tighten the Clamping Knob 11 . DO NOT overtighten. 2. To attach the instrument to the bracket using the QuickSet ® Mount 9 , slide the rear side of the instrument towards the QuickSet ® Release Button 13 along the QuickSet ® Rails 12 , until a click sound is heard. 3. To change the position of the instrument, loosen the Positioning Knob 10 and adjust the bracket until the instrument is in the desired position. Tighten the Positioning Knob 10 to secure the instrument position. DO NOT overtighten. 4. Power-ON and verify the line position by following the Power-ON procedures. Make additional adjustments if necessary. 5. To dismount the instrument from the bracket, press the QuickSet ® Release Button 13 , and pull the instrument until it is completely separated from the bracket.
