5.2. Installation Steps
- Disassemble: Carefully disassemble your AEG/gel blaster to access the motor housing and gearbox.
- Remove Old Motor: Disconnect the wiring and remove the existing 480 brushed motor.
- Install New Motor: Insert the T238 BL-480 Brushless Motor into the motor housing. Ensure the pinion gear properly engages with the gearbox bevel gear.
- Connect Wiring: Connect the motor wires to your AEG/gel blaster's wiring harness. Ensure correct polarity.
- Reassemble: Carefully reassemble your AEG/gel blaster.

6. Operating Instructions
6.1. Adjusting Motor Speed (RPM)
The T238 BL-480 motor features a built-in potentiometer for adjusting the motor's RPM from 50% to 100% of its maximum speed. This allows for fine-tuning performance to match different play styles or gearbox setups.
- Locate Adjustment Screw: Identify the small adjustment screw on the motor's end cap.
- Use Appropriate Tool: Use a small, non-metallic adjustment tool (not the hex key) to turn the potentiometer.
- Adjust RPM: Turn the screw clockwise to increase RPM and counter-clockwise to decrease RPM. Make small adjustments and test the motor's performance.

7. Maintenance
One of the primary benefits of a brushless motor is its reduced maintenance requirements compared to brushed motors. The absence of brushes eliminates wear and tear from friction, leading to a longer lifespan and consistent performance.
- Regular Inspection: Periodically inspect the motor for any visible damage, loose connections, or debris.
- Cleanliness: Keep the motor free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning.
- Pinion Gear: The pinion gear may require occasional inspection for wear. Use the provided 1.3mm hex key for removal if replacement is necessary. Do not attempt to open the motor casing for internal cleaning or lubrication, as this is generally not required for brushless motors and may void any potential warranty.
8. Troubleshooting
8.1. Common Issues
- Motor Not Responding:
- Check battery charge and connection.
- Verify all wiring connections are secure and correctly polarized.
- Ensure the motor is properly seated in the gearbox and not binding.
- Reduced Performance/Weak Trigger Response:
- Check battery health and charge level.
- Ensure the RPM adjustment is set appropriately (not too low).
- Inspect gearbox components for excessive friction or damage.
- Unusual Noise (e.g., Ticking):
- A ticking noise could indicate an issue with internal components, potentially a faulty capacitor. If this occurs, discontinue use and consider professional inspection or contact support.
- Ensure the motor's pinion gear is correctly meshed with the gearbox bevel gear. Improper shimming can cause grinding noises.
