3PR, 3PG Users Manual ii
Introduction The 3PR and 3PG Point Laser Levels (the Product) are battery-powered, self-leveling, professional grade instruments. Use the Product to layout reference points and to make sure conditions are level and plumb. The 3PR emits a dashed red line and is for use indoors. The 3PG emits a dashed green line and is for use outdoors.
3PR, 3PG Users Manual • Do not look directly into the laser with optical tools (for example, binoculars, telescopes, microscopes). Optical tools can focus the laser and be dangerous to the eye. • Remove the batteries if the Product is not used for an extended period of time, or if stored in temperatures above 50 °C. If the batteries are not removed, battery leakage can damage the Product. • Do not use the Product if it operates incorrectly. • Do not look into the laser.

3PR, 3PG Users Manual Level To determine if an existing item is level: To identify new level and grade marks: 1. Point the horizontal laser at the target area. 1. Put the bottom of the Product on a stable surface. 2. Measure the distance from the item to the laser. See Figure 2. 2. Turn the Product around on its center until the horizontal laser points to the target area. See Figure 1. 3. Place a mark at the level or grade point on the target area. 3.
Point Laser Levels Plumb Plumb The Product can send plumb marks up, down, or cantilevered over the edge of a building or shaft opening. To identify new plumb marks on a ceiling or roof: 1. Place a cross mark on the point to be transposed. 2. Center the down laser over the cross mark. See Figure 3. 3. Place a mark at the point where the up laser intersects the target area. To identify new plumb marks on a floor, repeat the steps above but interchange the down and up lasers.
3PR, 3PG Users Manual To determine if an existing item is plumb: Check Accuracy of the Product 1. Point either the up or down laser at the target area. Periodically check the accuracy of the Product. 2. Measure the distance from the item to the laser. See Figure 4. Check Accuracy of Level 3. Repeat step 2 at various distances from the Product. To check the accuracy of the level: If the measurements are the same from each distance from the Product, the item is plumb. 1.

Measure the distance between mark on target and mark and mark and mark on target If the distances are the same, the laser is level. . 9. If the distances are not the same, subtract the lesser measurement from the greater measurement and divide by two to calculate the difference of error.
3PR, 3PG Users Manual Check Accuracy of Plumb 4. Place a cross mark at the point where the up laser intersects the target area at the top of the site. To check the accuracy of the plumb: 1. Find a site that has a ≥3.05 m (10 ft) vertical height. 2. Place a cross mark at the bottom of the site. 3. Center the down laser on both axes of the cross mark. See Figure 6. 1 2 1 2 3 4 1 2 ≥ 3.05 m 10 ft 1 - 2 ≤ 6 mm @ 30 m 5. Turn the Product 180 ° on its center. 6. Repeat step 3 and step 4.
Point Laser Levels Maintenance Clean the Product Clean the case with a damp cloth and a weak soap solution. Do not use abrasives, isopropyl alcohol, or solvents to clean the case or optic windows. 1 Batteries Replace the batteries when the Indicator LED is yellow. To install or replace the batteries (See Figure 7.): 1. Remove the Product from the holster. 2 2. Remove the battery compartment lid. 3. Install three AA batteries with the correct polarity. 4. Replace the battery compartment lid. 5.
