2. Inspection and Adjustment (3) Bleeding the fuel system Bleed the fuel system according to the following procedures. When there is air in the fuel system, the fuel injection pump will not be able to function. 1) Check the fuel oil level in the fuel tank. Refuel if insufficient. 2) Open the cock of the water separator. 3) Loosen the air bleeding bolt on the water separator by turning 2~3 times to the counter-clockwise using screw driver or spanner. 4) When the fuel coming out is clear and not mixed with any bubble, tighten the air bleeding bolt. 5) Feed the fuel with the fuel priming pump or electro-magnetic fuel feed pump. z In case of the engine using the electro-magnetic fuel feed pump.
Turn the starter switch to the ON position and hold it in the position for 10~15 seconds to operate the fuel feed pump. z In case of the engine installed the fuel filter mounting with the fuel priming pump. The priming pump is on the top of the fuel filter mounting. Move the priming pump up and down to feed fuel until feel your hand slightly heavy. (4) Battery electrolyte level check and battery recharging F ire due to electric short-circuit z Make sure to turn off the battery switch or disconnect the negative cable (-) before inspecting the electrical system. Failure to do so could cause short-circuiting and fires.
z Always disconnect the (-) Negative battery cable first before disconnecting the battery cables from battery. An accidental "Short circuit" may cause damage, fire and or personal injury. And remember to connect the (-) Negative battery cable (back onto the battery) LAST. P roper ventilation of the battery area Keep the area around the battery well ventilated, paying attention to keep away any fire source. During operation or charging, hydrogen gas is generated from the battery and can be easily ignited. D o not come in contact with battery electrolyte Pay sufficient attention to avoid your eyes or skin from being in contact with the fluid.
The battery electrolyte is dilute sulfuric acid and causes burns. Wash it off immediately with a large amount of fresh water if you get any on you. 29
