2. Safety Information
Always observe basic safety precautions when using electrical appliances to reduce the risk of fire, electric shock, and personal injury.
2.1 General Safety Guidelines
- Read all instructions before operating the pump.
- Keep the work area clean and well-lit.
- Do not operate the pump in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Keep children and bystanders away while operating the pump.
- Do not immerse the pump's motor housing in water. Only the submersible barrel should be submerged.
- Always ensure the battery is fully charged before use.
- Use only the specified battery and charger for this pump.
- Do not use the pump to transfer flammable or corrosive liquids.
2.2 Overcurrent Protection
The SEESII WSP001 pump is equipped with an advanced overcurrent protection system for safe operation. This system automatically shuts off the pump and illuminates an indicator light if:
- The pump base is lifted out of the water.
- The hose becomes bent or obstructed.
- The bottom filter becomes clogged with debris (e.g., grass, mud).
This safeguard prevents motor damage and extends the pump's lifespan. If the pump shuts off due to overcurrent protection, identify and resolve the issue (e.g., clear clogs, straighten hose) before restarting.
