- Read “Recommended Practices for the Use of Manually Operated High Pressure Jetting Equipment”
- All personnel must be trained in safe operation of water blasting equipment
- Never aim WB gun at your body or others. Remember that Zero thrust guns discharge water in both directions
- Do not use damaged or leaking fittings
- Inspect hoses, lances, and nozzles for leaks, obstructions, or other damage before use.
- Never tie the gun trigger closed
- Always brace for gun re-coil
- Do not operate water blast equipment in pressure ranges outside of maximum working pressure.
- Do not modify or alter any equipment.
- Only replace gun tips with the same blast nozzles. Do not use different rated nozzles.
- Change both tips when servicing Zero Thrust Gun
- Flush hoses before replacing tips.
- If rupture disc burst, before replacing find and determine cause.
- When gun kits or tips are change, reduce engine “T” handle throttle valve clockwise completely before re-engaging the PTO. If not, the rupture disc will burst.

Care and Use of High Pressure Hose
Following are All Hose & Specialty’s list of Do’s and Don’ts for the proper and safe handling of a high-pressure hose. The improper use of a high-pressure hose can cause DEATH, personal injury or property damage. NEVER handle a leaking hose assembly. Treat any injury form high-pressure fluid seriously and seek immediate medical attention.
- Teat high-pressure hose with extreme caution. SPIR STAR hoses are wire reinforced hoses, not garden hoses and should be treated with the same care as a high-pressure containment vessel.
- When using hoses for water jetting, read and understand Recommended Practices for the Use of Manually Operated High Pressure Water jet Equipment (Water jet Technology Association.
- Always visually inspect for frayed, damaged, or wear spots before using.
- Check the hose end connections and threads for wear, rust, cracks, mechanical abuse or other deterioration, which could produce a dangerous projectile.
- Know the working pressure and burst pressures of all hoses before using them.
- Always use clean, filtered water to prolong hose life. Some plants water sources are high in sulfur, which attack stainless steel.
- Always clean, drain and coil hoses after use. Soda and water usually provide an excellent cleaning agent.
- Always wear protective gloves, eyewear and garments when handling high-pressure hose and water jet lances.
- Never use a hose with cuts or wire showing through the outer cover
- Never use a hose that has been kinked
- Don’t use a hose that has bubbles or blisters in the outer cover.
- Don’t exceed the bend radius and pressure rating for each hose.
- Don’t run over or crush the hose with heavy vehicles
- Don’t use a hose with corroded or leaking end connections. Take them out of service immediately.
- Don’t use hoses that have bee exposed to chemical attack or over temperature.
- Avoid using dirty water or water with sulfur compounds in it.
- Tests have documented that hoses fail more rapidly when using water sources from chemical plants and refineries.
- Don’t bend the hose over scaffolding or pull heavy equipment with the hose.
- Don’t let hose support its own weight off towers or buildings
- Don’t expect water jetting or hydraulic hose to last forever.
