PLAN AHEAD 

1. Always wear ear protection to cut noise and eye protection and / or face shield to prevent debris from flying or 

ricocheting into eyes and face which could result in serous injury.   

2. Dress safely in long pants and wear safety boots, safety gloves, safety helmets with visors, etc. Other protective 

equipment is advisable when using chemicals, cleaning detergents or other corrosive or abrasive substances.   

3. Do not operate pressure washing equipment if you have consumed alcohol or taken medication.   
4. Keep pets, children and bystanders a safe distance away from your work area. A minimum of 50 feet is recommended. 
5. Do not spray directly at glass or fragile objects.   
6. CAUTION after turning off your pressure washer and water supply, there is still high pressure water trapped in 

the system. You must release the pressure by triggering the gun after the engine has completely stopped. 

 

PRECAUTIONS FOR GASOLINE ENGINE 

1. Follow all safety precautions, operating procedures and maintenance listed in your engine operator’s manual 

which came with the pressure cleaner.

2. DO NOT fill the engine with gasoline when the engine is running, hot or near an open flame. DO NOT SMOKE.   
3. Do Not run power washers in an enclosed area for the exhaust fumes and hazard of noise. Exhaust fumes 

contain poisonous carbon monoxide gas. Breathing exhaust gases can cause serious illness or death.

4. Do Not touch or come in contact with hot mufflers, cylinders, cooling fins or hot exhaust gases as this may 

result in severe burns.   

5. Never tamper with governor spring, governor links or other components which may increase the speed (RPM) 

of the engine.   

6. Do Not operate pressure cleaners in the presence of flammable vapors or gases. When servicing pressure 

cleaning equipment, be sure to properly dispose of any flammable materials.

7. Do Not make adjustments to your equipment without first removing the spark plug.   
8. When transporting pressure cleaners, the fuel shut-off valves must be in the closed position, to prevent fuel 

from spilling out. 

 

MISCELLANEOUS SAFETY PRECAUTIONS 

1. Check all high pressure hose and fittings periodically for cuts or wear. Immediately replace all suspect 

components to prevent injury. Do not place high pressure hose on the engine muffler or drag across abrasive surfaces. 

2. Inspect pressure cleaner for oil, fuel and/or water leaks.   
3. Operate unit on level surface only. Otherwise fuel may spill on engine and/or pump. Lubrication may be 

insufficient if unit is not level.   

4. Never start power washers without adequate water supply.   
5. HIGH PRESSURE SPRAY CAN CAUSE SERIOUS INJURY Never point or aim the gun/wand at yourself or anyone 

else. Never put your hand, fingers or body directly in front of the spray nozzle. 

6. Do Not run the unit for longer that 2 minutes with spray gun in the closed position.   
7. Clean up spilled soap, fuel or oil immediately to avoid falls.   
8. Keep clutter out of work area to avoid falls.   
9. Never squeeze the spray gun trigger unless you are securely braced. The force of water through the nozzle is 

powerful enough to cause you to lose your balance and fall.   

10. Never attempt to use power washers on or near any electrical outlets, fuse boxes, transformers, high voltage 

wires, etc. Severe electrical shock or death may occur.

11. Do not use the appliance if important parts of appliance are damaged, e.g. safety devices, high pressure hoses, 

trigger gun.   

12. WARNING! Suds or soap powder are the only cleaning scour designed for this appliance. The use of other 

cleaning agent or chemicals may adversely affect the safety of appliance.

13. Only use genuine pressure cleaning equipment parts (eg.: High pressure hoses, fittings and couplings etc. ) for
