2) Tightening time Longer tightening time results in increased tightening torque. Excessive tightening, however, adds no value and reduces the life of the tool. 3) Different bolt diameters The size of the bolt diameter affects the tightening torque. Generally, as the bolt diameter increases, tightening torque rises. 4) Tightening conditions Tightening torque will vary, even with the same bolt, according to grade, length, and torque coefficient (the fixed coefficient indicated by the manufacturer upon production). IX. ACCESSORIES Use only bits suitable for size of chuck. Tightening torque will vary , even with the same bolting material (e.g. steel), according to the surface finish. Torque is greatly reduced when the bolt and nut start turning together. 5) Socket play Torque is lowered as the six-sided configuration of the socket of the wrong size is used to tighten a bolt. 6) Switch (Variable speed control trigger) Torque is lowered if the unit is used with the switch not fully pulled out. 7) Effect of Connecting Adaptor The tightening torque will be lowered through the use of a universal joint or a connecting adaptor.

For the final tightening, use the oneshot impact function. • Depending on the type of screw or the hardness of the material, the screw may not be completely flush with the surface. When working with cabinet boards or other more decorative materials where screws need to sit flush on the surface, use the lighter digital clutch's setting to avoid damaging the material, and then finish using the one-shot impact function. - 13 -
