A. IMPROPER USE OF FITTINGS HAZARD
Do not operate the pump with improperly connected, sized, worn or loose fittings, pipes or hoses. Operating
the pump under these conditions could result in personal injury and property damage.
1. Ensure all fittings, pipes and hoses are properly rated for the maximum pressure rating and flow of the pump.
2. Check all fittings and pipes for cracks or damaged threads.
3. Check all hoses for cuts, wear, leaks, kinks or collapse before each use.
4. Ensure all connections are tight and secure.
5. Use PTFE thread tape or pipe thread sealant (sparingly) to reconnect plumbing. Do not wrap tape beyond the last
thread, this will prevent tape from becoming lodged in the pump or accessories.
6. Apply proper sealants to assure secure fit or easy disassembly when servicing.
B. FROZEN LIQUID HAZARD
Do not operate the pump with frozen liquid. Operating the pump under this condition could over pressurize
and jettison the manifold from the crankcase causing personal injury and property damage.
1. Store pump or pumping system in an environmentally controlled room protected from freezing temperatures.
2. Follow procedures in TECH BULLETIN 083 to winterize pump.
C. CLEANING PUMP HAZARD
Do not use solvents that are flammable and toxic to clean or degrease equipment. Use of these solvents could
result in personal injury and property damage.
1. Follow safety instructions as found in MSDS or on packaging of each liquid.
2. Clean equipment in a well ventilated area.
3. Disposal of solvents to be in accordance with local, state and federal regulations.
D. OPERATING BEYOND SPECIFICATIONS HAZARD
Do not operate the pump outside the specifications of individual pump data sheet or service manual.
Operating the pump under these conditions could result in personal injury and property damage.
1. Do not operate the pump faster than the maximum recommended RPM.
2. Do not operate the pump at pressures higher than the maximum
recommended pressure.
3. Do not operate the pump at temperatures higher than the maximum recommended temperatures.
4. Do not use accessories that are not compatible or rated for the pump.
G. OXYGEN HAZARD
Do not charge Prrrrr-O-Lators (Pulsation Dampeners) with oxygen. Oxygen may cause an explosion causing
personal injury, death or property damage.
1. Use nitrogen only when charging pulsation dampeners, DO NOT USE OXYGEN.
2. Use proper charging tools to charge pulsation dampeners.
3. Charge pulsation dampener within specifications stated on data sheet to assure proper pulsation dampening and
prevent failure of bladder.
H. FALL HAZARD
Do not operate pressure washer while standing on slippery or unstable surface unless extraordinary safety
precautions are observed. Pressure washing may create slippery surface on which a person may slip and fall
causing personal injury or death.
1. Wear suitable footwear to maintain a good grip on wet surfaces.
2. Do not stand on ladders or scaffolding.
3. Do not over reach or stand on unstable supports.
4. Keep good footing and balance and hold gun with both hands to control kick back.
