How to Use a Laser Level on Land

Stand a tripod on the ground. Tighten down the leg locks on the tripod with your fingers. Screw the platform screw on the top of the tripod tightly into the tripod socket on the bottom of the laser level.

Slide the power switch on the back of the laser level on. Let the laser level self-level itself; level the laser by hand using the bubble on the top and adjusting the legs of the tripod if no self-leveling mechanism is included.

Rotate the tripod's platform so that the front of the laser level is pointing toward the wall where the concrete is to be poured. Tighten the knob on the tripod to lock the laser level so that it can no longer be moved.

Wrap the laser receiving module's strap around the measurement pole about a third in from one end. Tighten the strap.

Place the end of the pole farthest from the laser receiving module against the base of the wall. Stand the pole against the wall. Slide the power switch on the laser receiving module to the "On" position.

Loosen the strap on the laser receiving module. Raise or lower the module to follow the direction that an arrow on the LCD screen of the module is indicating. Stop moving the module when the beeping is regular and a flashing green light appears on the screen. Tighten the module's strap.

Place the pole against the vertical grade stake that is away from the wall and designates where the concrete will be poured. Raise or lower the pole until you hear beeping from the module indicating a level line. Draw across the bottom of the pole on the grade stake with a pencil. The line is level with the elevation of the bottom of the wall.

Measure 1-1/4 inches down from the drawn line to indicate the height that the concrete should have when poured to have the appropriate slope
