- Lightweight combat
Compared with traditional copper and iron water guns, it is about 35% lighter, does not cause fatigue when held for a long time, and speeds up the rescue movement line.
- Corrosion-resistant and impact-resistant
The main body is made of aviation-grade aluminum alloy, with a hard surface oxidation treatment. It is resistant to acid and alkali, shockproof and wear-resistant, and can adapt to harsh rescue environments.
- Modular interfaces can be freely selected
The standard and custom interfaces cover mainstream systems such as Storz, GOST, BS336, and Franch, making it easy to connect with global devices.
- Ergonomic grip
Anti-slip texture and temperature-friendly heat insulation design ensure stable operation even when wearing gloves, suitable for both winter and summer.

Practical operation
Fast connection test
1.Clean the interface:
Before connecting, use your fingers to wipe the sealing surfaces of the water hose interface and the gun body interface to ensure there are no sand particles or impurities.
2.Align the snap-in clip:
Align the protruding ears of the hose connector with the grooves of the gun body interface, and push it in horizontally all the way to the end.
3.Rotary locking:
Listen for a clear "click" sound, and confirm that the two protruding ears are securely locked. Perform a manual gentle pull test to ensure they will not come apart.
4.Do not use tools to forcefully tighten! Lock it by hand and it will meet the sealing requirements.
Switching among three spraying modes
Mode 1: Direct current jet - Powerful impact, directly targeting the fire source
Operation: Rotate the rotating adjustment ring at the tip of the gun clockwise to the position marked "DC".
Gesture: Hold both hands together in front of you. The front hand should grip the anti-slip area at the front of the gun body, and the rear hand should firmly hold the handle at the end of the gun. Stand sideways with your body and lower your center of gravity.
Usage: To extinguish large-scale open fires, for demolition, and for long-distance water spraying.
The water pressure should be gradually increased from low to high to avoid water hammer impact.
Mode 2: Spray water - for covering and cooling, creating a water curtain
Operation: Rotate the rotary adjustment ring counterclockwise until it reaches the position marked "Spray".
Gesture: It can be performed with either one hand or both hands, making it easy to perform a sweeping motion in a fan shape.
Usage: Cooling the fire scene, dispersing smoke, diluting chemical leaks, protecting unburned surrounding materials.
The misty water has a wide coverage area. Please keep a safe distance from the fire source to prevent steam burns.
Mode 3: Water Curtain Self-Supporting - Blocking Heat Radiation and Creating a Safe Zone
Operation: In spray mode, continue to turn the adjustment ring backward by half a notch (for some models, there is an independent water curtain setting), or slightly close the valve at the end of the gun to make the water curtain wider and more spread out.
Purpose: To establish a protective barrier for firefighters at the front of a high-temperature fire scene, providing cover for demolition or evacuation.
This mode consumes a large amount of water. Ensure that the water supply is sufficient.

Practical skills and safety tips
Anti-backflow: When using the water gun, the nozzle must be aimed in a safe direction or at the ground first. Wait until the pressure stabilizes before aiming at the target. The backflow force of the high-pressure water jet should not be underestimated.
1
The stance while holding the gun should be as stable as a rock.
Water hose supervisor: Positioned behind the water gun operator, responsible for straightening the water hose to prevent entanglement and tripping, and following instructions to slowly open/close the water supply valve to avoid sudden pressure changes.
Communication: Use clear and concise commands, such as "boil water", "apply pressure", "stop water supply", "switch to spray mode".
2
Collaborative Operations: Water Hose Management and Coordination with Water Gun Operators.
Chemical fire scene: Use the spray mode first for dilution and isolation. After the operation is completed, the gun body must be thoroughly rinsed with a large amount of water, especially the interfaces and adjustment parts.

Maintenance Guide
The Golden Three Steps, none of which can be omitted:
Immediately rinse (complete within 30 minutes after returning from the fire scene)
Rinse the outside and inside of the water gun with clean running fresh water.
Focus on thoroughly cleaning the gaps of the adjustment ring, switches, etc., to remove smoke residue, chemical residues and impurities.
Action: Switch all modes and allow the water to flow through each channel.
Inspection and drying (completed on the same day)
Check for sealing integrity: After drying, inspect each interface and switch area for any traces of water droplets.
Check the moving parts: Ensure that the rotating adjustment ring and the valve switch are still functioning smoothly and there is no sticking.
Complete drying: Place it in a well-ventilated and cool area to dry naturally. Do not expose it to direct sunlight.
Regular maintenance (monthly or after each 10 uses)
Light lubrication: At the rotational axis of the adjusting ring, apply a small amount of silicone-based lubricant (do not use oily grease, as it is prone to attracting dust).
Sealing ring inspection: Visual inspection of all sealing rings inside the gun for any cracks or deformations. The spare sealing ring package included with the product can be replaced at any time.
Storage: Close the interface protection cover and store it on a dry equipment rack.

FAQ
Q: Is the daily maintenance complicated?
A: It's very simple. Just follow these three steps:
- Post-war cleaning: Rinse the surface and interior with clean water to remove debris.
- Regular inspection: Check whether the sealing ring is intact and whether the rotating parts are functioning smoothly.
- Storage: Keep in a dry place and avoid prolonged exposure to sunlight and rain.
Q: Compared to traditional copper or stainless steel water guns, what are the advantages?
A: The core advantages are threefold: lightweight, durable, and energy-efficient.
- Light: The weight has been reduced by more than one-third, significantly reducing fatigue during movement, lifting, and prolonged operation, thereby enhancing efficiency.
- Nai: Aluminum alloy is inherently resistant to chemical corrosion, making it particularly suitable for use in chemical fire situations or in coastal areas, and it has a longer service life.
- Province: By ensuring the same performance level, we can help you save the costs of purchasing individual equipment and the subsequent maintenance costs.
Q: How can I determine whether I should buy a basic DC model or a dual-purpose model?
A: Choose based on the main task scenario:
- Basic straight water gun: Suitable for teams with a single task and a focus on maximum range and impact force, such as in warehouses and airports.
- Spray/Direct Current Dual Function Type: Suitable for complex comprehensive firefighting operations. This model can be used for multiple purposes with one gun, offering the highest cost-effectiveness and covering over 90% of fire situations.
Common abnormal situations
| Phenomenon | Possible reasons | Quick solutions |
| A small amount of water leakage at the interface | There are sand particles or wear on the sealing ring | Disconnect the connection, clean the sealing groove, and replace the sealing ring |
| The adjusting ring is difficult to rotate. | Internal dirt or impurities get stuck after being heated. | Rinse with clean water and gently tap around the adjusting ring. Spray in a silicone-based lubricant. |
| The water spray is scattered and the range is insufficient. | There is an object blocking the nozzle of the gun head. | Turn off the water supply, remove the nozzle, and use a fine needle to clean it. |
| The valve is closed too tightly. | The internal valve stem lacks lubrication. | Drop a small amount of the special fire valve lubricant through the valve gap, and then open and close the valve several times. |
Remember: When the problem cannot be solved quickly, immediately switch to the backup gun to ensure combat effectiveness.
The MED water gun is your reliable companion in every emergency. Proper use and meticulous maintenance will ensure that it performs at its best every time it goes into action.
