An Auto-Level is a Professional Leveling Tool used by Contractors, Builders, Land Surveying Professionals, or the Engineer who demands accurate leveling every time. Auto Levels set up fast, are easy to use, and save time and money on every job
Guidelines and Safe Uses. The level unit is set-up in a position which gives a clear view of all points to be leveled, or as many as is feasible under site conditions. Each position where the level is set-up is referred to as a station, and stations may be marked for future reference by means of a timber peg, steel pin, brass tag or paint mark as befits the conditions. Marking of stations in this way allows levels and angles to be checked at a later date if a discrepancy is found.
After use make sure all parts are in for another use. Clean up the tripod after all uses. Service your automatic level occasionally. Storage and Handling Store in a cool place away from dust and impurities. Never use during rain. Avoid dropping the automatic level.
The automatic level is used in the constriction industry and is used for the following: It is used to find the slope distance of a hill. It is used to level the surface of the land.
A set square or triangle object used in engineering and technical drawing, is aimed at providing a straightedge at a right angle or other particular planar angle to the baseline. The simplest form of set square is a triangular piece of transparent plastic (or formerly of polished wood) with the centre removed. The set square used most commonly bears the markings of a ruler and a half circle protractor; the outer edges are typically beveled.These set squares come in two usual forms, both right triangles: one with 90-45-45 degree angles, the other with 30-60-90 degree angles. Combining the two forms by placing the hypotenuses together will also yield 15° and 75° angles. They are often purchased in packs with protractors and compasses. Here, the body of the object is cut in half and rejoined with a hinge marked with angles. Adjustment to the marked angle will produce any desired angle up to a maximum of 180°.
A wrench is a tool used to provide grip and mechanical advantage in applying torque to turn objects usually rotary fasteners such as nuts and bolts. Guidelines for safe use.
