What are some important safety precautions to be aware of when operating the pump?
Never inhale exhaust gasses as they contain carbon monoxide, a colorless, odorless and extremely dangerous gas which can cause unconsciousness or death. Never operate the pump indoors or in a poorly ventilated area, such as a tunnel or cave. Exercise extreme care when operating the engine near people or animals. Keep the exhaust pipe free of foreign objects. Gasoline is extremely flammable and its vapors can explode if ignited. Do not refuel indoors or in a poorly ventilated area. Be sure to stop the pump prior to refueling. Do not remove the fuel tank cap nor fill the fuel tank while the engine is hot or running. Allow the engine to cool at least 2 minutes before refueling. Do not overfill the fuel tank. If fuel is spilled, wipe it away carefully and wait until the fuel has dried before starting the engine. After refueling, make sure that the fuel cap is secured to prevent spillage. Do not operate the pump while smoking or near an open flame. Do not use around dry brush, twigs, cloth rags, or other flammable materials. Keep the cooling air intake (recoil starter area) and muffler side of the engine at least 1 meter (3 feet) away from buildings, obstructions, and other burnable objects. Keep the pump away from flammables and other hazardous materials (trash, rags, lubricants, explosives). Be careful of hot parts. The muffler and other engine parts become very hot while the pump is running or just after it has stopped. Operate the pump in a safe area and keep children away from the running pump. Do not use the diaphragm pump for the mixture of water and oil. Do not touch the spark plug and ignition cable when starting and operating the engine. Operate the pump on a stable, level surface. If the engine is tilted, fuel spillage may result. Do not transport the pump with fuel in the tank or with the fuel strainer cock open. Keep the unit dry (do not operate it in rainy conditions). Operating the engine at a steep incline may cause seizure due to improper lubrication even with a maximum oil level.
What should I check before operating the pump?
Carefully check fuel hoses and joints for looseness and fuel leakage. Check bolts and nuts for looseness. Check the engine oil and refill if necessary. Check the fuel level and refill if necessary. Keep cylinder fins and the recoil starter free of dirt, grass, and other debris. Wear snug-fitting working clothes when operating the engine.
