•To attach the laser tool, screw the 1/4"-20 mount 13 into the tool
and tighten. Turn the knob and tool together as necessary to properly
position the laser line or lines.
•To adjust the height of the laser lines, adjust the height using the
adjustment knob on the ceiling grid clip 18 of the BM 3 17.
Tip: It is recommended to clean the back of the L-bracket 16 before
mounting via the magnets to make sure you have the optimal mag-
netic hold of the tool on the mounting surface. Cleaning this will re-
duce the amount of interference from any dust or debris between the
magnets 15, L-bracket 16 and the mounting surface on the jobsite.
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
measuring tool to adjust to the ambient temperature before putting it
into operation. In case of extreme temperatures or variations in tem-
perature, the accuracy of the measuring tool can be impaired.
Avoid heavy impact to or falling down of the measuring tool.
Damage to the measuring tool can impair its accuracy. After heavy
impact or shock, compare the laser lines with a known horizontal or
vertical reference line.
Switch the tool off during transport. Slide the On/Off switch 2 to
the "Off" position when transporting the measuring tool. This locks the
leveling unit, which can be damaged in case of intense movement.
