400e Airsoft FAQs

How Do I Operate My AEG?

1. Start with a freshly charged battery.
2. Remove the battery cover and install the battery securely.
3. Load the magazine:
   • Fill the reservoir with BBs.
   • Use the wheel on the bottom of the magazine to load BBs into the firing side.
4. Insert the magazine into the rifle.
5. Select semi-auto or full-auto mode, and you are ready to shoot.

How Do I Adjust the Hop-Up?

1. Open the side cover to access the hop-up adjustment wheel.
2. Turn the wheel to increase or decrease the hop-up.
   • Heavier ammunition: Requires more hop-up.
   • Lighter ammunition: Requires less hop-up.
3. Adjust until the BBs fly as flat and far as possible.

What Should I Do If My Gun Isn’t Working or Is Faulty?

• Check the Battery: Ensure it is fully charged and in good working condition.
• Inspect the Barrel: Make sure the barrel is clean and free of jams.
• Ammunition: Always use clean, new BBs. Reusing ammunition can cause jams.
• Motor Issues:
  • If the motor is turning but the gun isn’t firing, adjust the set screw on the bottom of the grip.
  • Adjusting the screw can help the motor engage the gearbox properly.

For a detailed guide on set screw adjustments, refer to this video: Set Screw Adjustment.

Firing Issues

If your rifle isn’t firing, follow these steps:

1. Check the Battery:

   • Use a voltmeter to confirm the battery is fully charged.

2. Inspect for Gear Jams:

   • Gear jams can occur due to firing with a weak or undercharged battery or storing the gun with the gears partially cycled.
   • Symptoms of a gear jam include:
     • Clicking noise when pulling the trigger.
     • The motor in the pistol grip “twitches.”
     • The wiring and battery become warm.
   • Important: Stop firing if you notice these symptoms to avoid overheating and damaging your gun or battery.

3. Resolve Gear Jams:

   • Adjust the set screw on the bottom of the handle to ease the motor off the gearbox.
   • Refer to this guide: Set Screw Adjustment.

How Do I Connect the 9-Pin Low Voltage Buzzer Alarm?

The buzzer alarm connects to the balance lead of the LiPo battery, not directly to the 400e.

• For instructions, watch this video: Connecting the Voltage Alarm.

Tips:

• Disconnect the battery from the 400e when not in use.
• Always unplug the voltage alarm from the LiPo battery when not in use to prevent power drain.
