Accuracy Adjustment
Checking Vertical Accuracy
To check the vertical accuracy of your Rugby laser, place the unit in the
laydown position on a flat, level surface approximately 50-100 ft (15-30 m)
from a wall.
• Hang a plumb line on the wall.
• Move the Rugby until the vertical, rotating beam is aligned to the plumb
line.
• If the rotating beam is not plumb, adjustment is necessary.
