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.
