(Note: Be sure to <br />position the base so that the tower can be hinged In the direction where there <br />are no obstructions.) Mark off a circle approximately 2 to 3 Inches larger than <br />the cyIInder. <br />3. Dig a hole 4 feet deep (deep enough to completely bury the cylinder below ground <br />I eve I). <br />4 Drop the cylinder In the hole and with It as yertical as possible throw the soil <br />back Into the cylinder and around it, tamping It solid after every 6 to 8 Inches <br />of fill. (Note: Be sure cylinder Is flush or below the ground surface. See <br />Draw Ing C750409.) <br />5. When the cylinder Is approximately one-half full of dirt, attach the base twer <br />section to the pipe sleeves of the base as shown on Drawing C750409 This Is <br />necessary to avoid distortion of the cylinder as you continue to fill and tamp <br />the soil In the base. <br />6. Continue to fill and tamp the soil into the cylinder to within 6 Inches of the <br />top. <br />7. Plumb the tower section by placing a level on the outside of each leg adjusting <br />to the plumb position by loosening and re-aligning the BXC31 angle <br />brackets until the tower Is plumb. (Note: The brackets must be extremely <br />tight when the tower section Is plumb.) <br />Remove the top 1/2” x 3-1/2" bolts on the pivot side of the tower that <br />the pipe sleeves to the yokes. Then remove both bolts on the side opposite the <br />pivot direction. The section can now be hinged to the ground. <br />Assemble the rest 6f the tower as per BX tower Instructions. Hinge the tower <br />up and when vertical put the 1/2" x 3-1/2" bolts back through the yokes and <br />pipe sleeves. Then tighten all base bolts securely. <br />10. Complete filling the cylinder with dirt and tamp firmly. <br />11 After Installation Is completed, the base should be rechccked In about 30 days <br />t7be surethat the hardware r«;alns tight and It should be rechecked every six <br />months. <br />12. Towers Installed In sand or gravel should be guyed or bracketed. <br />NOTES . . <br />Do not Install towers near power Unas. All towers should he Installed °“T oT <br />falling distance of power lines since every electrical and teleohone wire should be <br />considered dangerous. <br />Unarco-Rohn recomands antl-cIImb s^tlons on all towers to prevent unauthorized <br />persons from climbing towers. <br />All antenna Installations must be grounded per local or national codes. <br />All towers should be Installed by experienced and trained personnel. <br />All types of antenna installations should be Thorougnly Inspect^ by , <br />personnel at least twice a year and remarked with hazard and warning labels to In <br />sure safety and proper performance. <br />8. <br />9.
