Azimuth safety collar installation on pipe support Note that the installation of the antenna should be accomplished by qualified personnels, and well trained person in fair climatic conditions (In any case, always respect the safety regulation in effect in the country). Activities involving the use of pulleys, ropes, carabiners and others accessories to hoist antennas and associated products are inherently dangerous. You are responsible for your own actions and decisions. The use of hoisting systems must be done by qualified and skilled personnel. Always use certified and controlled equipments, and be sure to respect the breaking load and the working load limit of each element (pulleys, ropes, carabiners ). RFS disclaims any responsibility in case of non repect of these warnings..

Elevation fine adjustment (Feed system not shown) Torque tighten the 2 M10 screws (refer to torque table joined), then loosen it, ¼ turn Principle for an installation with a left offset Loosen or tighten M10 brass nuts to adjust the Elevation After complete elevation fine adjustment, torque tighten the 2 M10 screws 13. Azimuth fine adjustment (Feed system not shown) Loosen M12 nuts of the 2 V-Bolts Principle for an installation with a left offset Loosen or tighten M10 brass nuts to adjust the Azimuth. After complete Azimuth fine adjustment, lock each first nut of the V-bolts (greased) at the specific torque, (refer to torque table joined) then tighten the second nut against the first one using usual wrench (do not use 2 wrenches to fix the second nut). Then tighten the 2 brass nuts M10 of the Azimuth spindle. NMT e 10/11
