TOOLS REQUIRED

The following tools will be needed to perform this maintenance evolution:

1.Small flathead screwdriver

2.Needle nose pliers

TIME REQUIRED

It is estimated that it will take (1) person twenty min- utes to perform this task, not including all of the items indicat- ed in the section entitled “PREPARATION”.

IMPORTANT NOTES

1.Read these instructions thoroughly before attempt- ing this maintenance evolution. Become familiar with the parts and what actions need to be taken. This will save time in the long run!

2.Note: Even though the photos in these instructions show a vacuum breaker that has been removed from the plumbing assembly, these maintenance steps could be performed with it installed so long as the requirements in the section entitled “PREPARATION” have been met.

Removing the cap

4.Set the cap to the side.

5.Using the needle nose pliers, gently lift out the plunger and set to the side. Examine the brass seating surface inside the vacuum breaker. The plunger is required to sit flat on this sur- face so it must be free of defects, imperfections and the like. If there is debris, remove it. If it is chipped or cracked then the vacuum breaker must be replaced. Failure to do so may result in the vacuum breaker not working according to its design and could result in damage to the dishmachine.

JPX-300NSU specifications

The Jackson JPX-300NSU is an advanced self-defense tool that combines cutting-edge technology with user-friendly design, making it a reliable option for individuals seeking personal protection. This innovative device is not just a standard pepper spray; it incorporates unique features that enhance its functionality and effectiveness.

One of the standout characteristics of the JPX-300NSU is its propulsion system. Unlike traditional aerosol sprays, this device uses a pyrotechnic propellant to launch a pepper-based projectile at a high velocity, allowing for a range of up to 7.5 meters (approximately 25 feet). This extended range gives users the advantage of keeping an intruder at a safe distance while still effectively incapacitating them. The projectile disperses upon impact, creating a broad aerosol cloud that disorients an assailant.

The JPX-300NSU is designed for ease of use, featuring a simple, intuitive trigger mechanism that allows for quick deployment under stress. Its ergonomic grip ensures a comfortable hold, even in high-pressure situations. Additionally, the device is equipped with a safety lock to prevent accidental discharge, which is essential for ensuring user safety.

Another notable feature of the JPX-300NSU is its ability to shoot two cartridges in rapid succession. Each cartridge is pre-loaded with a potent pepper formula, which is known for its debilitating effects. The device comes with interchangeable cartridges, allowing users to select the specific formulation that suits their needs, whether it's a standard pepper spray or a more specialized formula with additional irritants.

The robust construction of the JPX-300NSU ensures durability and reliability. Its lightweight and compact design make it easily portable, fitting conveniently in a purse or pocket. This makes the device not only effective but also accessible for everyday carry.

Moreover, the JPX-300NSU is equipped with a clear viewing window that allows users to assess remaining contents, ensuring they are always aware of their device's readiness. This foresight can be crucial in potentially dangerous situations.

In conclusion, the Jackson JPX-300NSU is an innovative self-defense tool that blends cutting-edge technology with practical design. Its extended range, rapid-fire capability, and specialized cartridges make it a formidable option for personal protection, all while maintaining user safety and ease of use.
