SAFETY CAUTIONS Warning Risk of fire and explosion Never use open fire When topping up or replacing fuel or engine oil, or cleaning parts in wash oil, do not light a match, smoke or use any other open fire nearby. Doing these is extremely dangerous as fuel and oils can catch fire. Completely wipe off any spilt fuel or engine oil as they are flammable and can be a fire hazard. Store fuel and engine oil in a well-ventilated place. Firmly tighten the cap of the container. Keep things tidy around the engine Keep fuel, engine oil or any other flammables as well as explosives and other dangerous materials away from the engine. These materials can ignite and explode.

Keep the engine and the surrounding area free of waste, dirt, foreign matter, etc. These substances can be a fire hazard and invite overheating. In particular, ensure that the top of the battery is clean after service operations. Any waste left on the battery can cause short circuit. Keep a running engine at least 1 m (3.3 ft.) away from the surrounding building or equipment to eliminate the risk of fire. Do not open the crankcase until it has cooled down Do not attempt to open the crankcase side cover immediately after the engine is stopped. Wait at least 10 minutes until the engine has sufficiently cooled down.

If fresh air flows into the crankcase with the engine still hot, the remaining mist of oil may ignite and cause explosion. Pay attention to fuel and oil leakage If leakage of fuel or oil is found, immediately take measures to stop it. If leaking fuel or engine oil spills over the heated engine, fire may start, possibly leading to bodily injury or equipment damage. Use explosion-proof light When checking fuel, engine oil, coolant, battery electrolyte, etc., use explosion-proof light. If ordinary light is used, these fluids may ignite and explode. Prevent short circuit Before inspecting or servicing the electrical/electronic system, disconnect the negative (-) cable from the battery terminal.

Failure to observe this can cause the circuit to short, possibly starting a fire. Loose terminals and damaged cables/wires can cause short circuit or even fire. Before carrying out service operation, check for loose or damaged components and repair or replace as required. Keep fire extinguisher and first-aid kit at hand Keep a fire extinguisher at hand. Become familiar with the handling of the fire extinguisher. Store a first-aid kit at the designated place. The kit should be kept fully supplied so that it can serve the purpose at any time. Establish a set of actions to take in the event of fire or accident, including emergency contact numbers and means of communication. 0 - 2
