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

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

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

        Warnings<\/h2>\n
          \n
        • 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<\/strong> (e.g. an M130 spring may deliver performance corresponding to M140-150), and their actual output could exceed the declared durability limits of the gearbox. We recommend using only the included Specna Arms springs<\/strong>. When using springs from other manufacturers, we recommend choosing an M120 spring<\/strong> to reduce the risk of damaging the rifle with a spring that does not correspond to its stated rating.<\/li>\n
        • When replacing a spring with progressive (non-uniform) coils<\/strong>, make sure that the end of the spring with the more tightly wound coils is positioned on the spring guide<\/strong>, facing outwards from the gearbox.<\/li>\n
        • Never store the rifle with the battery connected.<\/strong><\/li>\n
        • Never store the rifle with pre-cocking activated.<\/strong> Before storing the rifle, always release the piston to its forward position to prevent unnecessary stress or damage to the spring.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"
