1. Introduction
The SPLATRBALL SRB370 Full Auto Water Bead Blaster is designed for outdoor recreational use, firing 7.5mm Splat-R-Ball water bead ammunition. This blaster features a 375-round internal reservoir and can shoot up to 7 rounds per second at a velocity of up to 135 feet per second. The water balls are soft, non-staining, and require virtually no cleanup, as they disintegrate on impact.

3. Setup
- Prepare Water Beads:
Place the 2,500 SplatRBall water beads in a container with plenty of water. Allow them to soak for at least 4 hours, or until they expand to 7.5mm in diameter. Ensure they are fully hydrated for optimal performance and to prevent jamming. - Charge the Battery:
Locate the USB charging port on the blaster. Connect the provided USB charging cable to the blaster and to a compatible USB power source (e.g., wall adapter, computer USB port). The battery is a rechargeable 7.4V 500 mAh unit. Allow sufficient time for a full charge before first use. - Load Water Beads:
Unscrew the cap from the internal reservoir on top of the blaster. Use the foldable water ball loading funnel to carefully pour the hydrated water beads into the reservoir. Ensure the reservoir is securely closed after loading. - Attach Sling Clip (Optional):
If desired, attach the sling clip to the designated attachment points on the blaster for easier carrying during play. - Wear Safety Glasses:
Always wear the provided safety glasses before operating the blaster to protect your eyes from stray water beads.
