Important safety rules: • • • Turn off engine. Turn off engine and remove spark plug cap before cleaning, inspecting, or servicing the water pump. Guards / shields.
Operation – Preparing the Water Pump for Each Use Step Two: Select a Suitable Site WARNING Choose a suitable site for operating your water pump to avoid equipment damage and/or injury and possible death from carbon monoxide poisoning, electric shock, or fire. Choose a site that meets all of the criteria specified. Important safety rules: • Select a suitable site. Before using the water pump, you must select a suitable OUTDOOR location for installation and operation.
Operation – Preparing the Water Pump for Each Use 2. Outdoors only d. Place the water pump so that the muffler exhaust fumes will not be directed towards people or building air intakes. e. Ensure that working, battery-operated or battery back-up carbon monoxide alarms are used in any dwelling/structure that is in close proximity to the running water pump. WARNING: Never attempt to attach ductwork to the muffler system to allow for installation inside an enclosure.
Operation – Preparing the Water Pump for Each Use 5. Hearing protection The water pump can produce noise levels in excess of up to 95 dB in close proximity, which can be dangerous to human hearing with prolonged exposure. WARNING: Never attempt to attach ductwork to the muffler system to lower noise levels. This could cause hot air deflection, heat build-up, and increased exhaust back-pressure, resulting in possible exhaust leakage or damage to the water pump engine.
Operation – Preparing the Water Pump for Each Use Step Three: Fueling WARNING Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel. Use extreme care when handling gasoline. 1. Engine off / cool The engine must be off and allowed to cool at least two minutes before adding fuel. WARNING: A running engine is hot enough to ignite fuel. Never add fuel or remove gas cap if engine is running or still hot. 2. Outdoor location Fill fuel tank outdoors – never indoors.
Operation – Preparing the Water Pump for Each Use Static electricity and filling the gasoline tank: Static electricity can initiate from ungrounded gasoline tanks or containers, from flowing gasoline, and from persons carrying a static electric charge Static electricity can explosively ignite gasoline vapors that are present during the fueling process, resulting in serious burns to nearby persons.
Operation – Preparing the Water Pump for Each Use Step Four: Attach a suction strainer WARNING This pump is design to pump water only. Never use the water pump to pump flammable liquids. 1. Attach suction strainer A suction strainer should be attached to the suction hose. A suction strainer has holes or slots small enough to prevent large debris from working through and damaging the pump. 2. Keep the strainer Keep the strainer clean.
