      Instructions for putting the gun into operation<\/h2>\n

      Before you can fire the gun, you must activate the HAL ETU unit<\/strong> and follow this procedure exactly. Otherwise, the gun will not respond to the connected battery:<\/p>\n

        \n
      1. Set the fire selector to Safe.<\/li>\n
      2. Connect the battery and wait 3 seconds until you hear a beep.<\/li>\n
      3. Press and hold the trigger for 5 seconds until you hear another beep.<\/li>\n
      4. The gun is now ready for use.<\/li>\n<\/ol>\n

        Warnings<\/h2>\n
          \n
        • The battery and charger are not included<\/strong> and must be purchased separately.<\/li>\n
        • Before first use, the HAL ETU\u2122 unit must be calibrated (see above)<\/strong>.<\/li>\n
        • Springs from some manufacturers are significantly overrated in terms of actual power<\/strong> (e.g. an M130 spring may deliver performance corresponding to M140-150), which could exceed the declared durability of the gearbox. We recommend using only the supplied Specna Arms springs<\/strong>. When using springs from other manufacturers, we recommend choosing springs rated at M120<\/strong> to reduce the risk of damage caused by a spring whose actual strength does not correspond to its marking.<\/li>\n
        • When replacing the spring with one featuring progressive (non-uniform) winding<\/strong>, make sure that the end with the tighter coils is positioned on the spring guide<\/strong>, facing outwards from the gearbox.<\/li>\n
        • Never store the gun with the battery connected.<\/strong><\/li>\n
        • Never store the gun with pre-cocking activated.<\/strong> Before storage, always release the piston to its forward position to prevent unnecessary stress and potential damage to the spring.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"
