These "L“ brackets are bolted through the slotted holes on the rotor and top plate with the short legs of the "L" bracket toward the outside of the tower. See Orawing C-750429. 2. Run the U-bolt through the open side of the formed "V" clamp and into the "L" bracket placing the 5/16" nuts and washers on the U-bolt loosely. 3. To Install the mast, place one end of It through the upper U-bolt assembly end plate and slide It down into the lower U-bolt assembly. Then tighten the U-bolt assembly to hold the mast. 4. Adjustments to make the mast vertical may be made by moving the "L" brackets In the slotted holes. The HBX - Heavy Duty and HOBX - Extra Heavy Duty Towers are furnished with a mast clang) Installed on the top plate aade from a pipe floor flange, which Is provided with three bolts to be used as set screws to secure the mast. The bo* of hardware consists of one U-bolt assembly as described above and It can be Installed on the lower plate as 1$ Instructed above. If required. ASSEMBLY INSTRUCTIONS BREAKING DOHW BUNDLE 1.If your tower Includes the 8* mast and/or three 4* base stubs, remove them. Remove the package of nuts, bolts, and washers. 2.Lay the bundle on Its side and remove the tower sections. Start with the Innermost section of the package (the smallest section) and remove by pulling out with quick, firm jerks. It is not necessary nor desirable to pry the tower sections out with tools as damage may result. 3.Inspect all tower sections on delivery to make sure there are no loose or broken rivets caused by transport mis handling. If a rivet Is broken or loose. It should be replaced by a snug-fitting machine bolt and nut, securely tightened. TOWER After you have chosen the desired type of base for your tower (concrete base with 8X6 concre^base concrete base, or BXC\ cylinder base which hinges over and requires no concrete) and It Is oro^rly Installed per base instructions, bolt the base section (the largest section) to the base. Proceed with the erection as follows: I by bolting together each section with the proper size bolts. To erect the tower, section by section vertically, you should use an EFBX erect.on flxtuw for J'AlsIng the section being Installed into the previous section. (Note: Do not use an erection fixture to lut more than the weight of one tower section at a time.) By using BXHC or BXCA base the tower can be assembled on the ground and hinged up using extreme caution. When hinging up. watch for power lines, trees, etc. 3. Loose, missing or faulty rivets should be replaced with a similar size nut and bolt which can be obtained at any local hardware store. NOTE; 3/8" bolts are to be used on BXl, BX2 and the tep of BX3 sections. 9/16" bolts are used on the bottom of the 6X2 and all sections from BX4 through BX8 (BX8 Is the largest section).* One set of cross braces on one face of the too section 1$ purposely left off to allow easy wcess to the rotor elate for Installing the mast and rotor. (Note: Only one person should be on the tower at one time.) NOTES ON installing BCTATCRS Most all makes of rotators can be Installed on the rotor plate inside tne top tower J* ^itrilth There is a short piece of tubing furnished with each tower that can be used as a (fo^J ^ the mast clmm) installed on the top plate as Is described under the heading of Mast Assembly. Oo not Install rotators on the HOBX top plate.. for the HBX - Heavy Duty and HOBX - Extra Heavy Duty Towers, when a rotator is used a ^ piece Of or Pl^ I.O. larger than the 0.0. of the mast can be Installed in the pipe flange clamp and used as a bearing sleeve for mast to turn in. FOR installing the ROTATOR ITSELF. FOLLOW THE PROCEDURES OUTLINED BELOW: Sow. inline model rotators mount directly to the rotor plate. (The lower housing of tim rotator Is "O* 4« dnim 1 'he necessary holes For mounting most rotors are pre-Ounched In the olate Itself snd theis done.) ne '’•cessary mji«« « .. . . . . . . from the bottom of the plate upward\ holts ^Or mouniinq prwyuru.neu m s/i**.* - Z ^ ^ i « _ IliJ ?!: i™ to the upper housing (4.1/a- * r bolts) are to be inserted from the bottom of the plate upward ® ?t It desirable to place J/B" nuts to act as spacers between the rotor plate and the rotator.and into tne rotor.
