6. Maintenance
6.1 Cleaning
Wipe down the blaster with a damp cloth as needed. Do not submerge the blaster in water. Ensure no water enters the internal electronic components.
6.2 Storing Gelfire Rounds
Store hydrated Gelfire rounds in an airtight container away from direct sunlight and extreme temperatures to prevent them from drying out. If rounds dry out, they can be rehydrated by soaking them in water again.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Blaster not firing / Rounds getting stuck | Rounds not fully hydrated or jammed in the feeding mechanism. | Ensure rounds are fully hydrated (3-4 hours soak time). Gently shake the blaster to dislodge any stuck rounds. If the issue persists, remove the hopper and clear any visible obstructions. |
| Blaster not turning on | Battery is not charged or not properly inserted. | Ensure the rechargeable battery is fully charged and correctly inserted into the blaster. Check the power switch is in the 'ON' position. |
| Low firing velocity | Battery charge is low. | Recharge the battery. Performance may decrease as the battery drains. |
