5.3. Use of K-150 with petrol engine
WARNINGS:
oDo not run the engine in a closed area. Exhaust gas contains carbon monoxide, an odourless and deadly poison.
oGasoline is extremely flammable and can be explosive under certain conditions. Stop engine and allow the
engine to cool off before refuelling.
oWhen refuelling or working on the carburettor / fuel circuit, make sure the area is well ventilated, do not
smoke and stay away from any source of flame or sparks. Do not fill the tank so the fuel level rises into the filler
neck or level surface of the level gauge. If the tank is overfilled, heat may cause the fuel to expand and overflow
through the vents in the tank cap. Wipe off any spilled gasoline immediately.
oKeep the engine at least 1 mtr. away from buildings, obstructions and other burnable objects. To avoid getting
an electric shock, do not touch the spark plug or spark plug lead during engine running.
oTo avoid a serious burn, do not touch a hot engine muffler. Before you service or remove parts stop engine and
allow the engine to cool down.
oAlways remove the spark plug lead from the spark plug when servicing the engine to prevent accidental starting.
