(3) Drain the fuel filter
When water and dirt are mixed in with the fuel, it becomes impossible for the fuel injection pump
and the valve to work. Drain periodically to keep the filter from becoming clogged. When ther<|
is a lot of drain collected in the oil/water separator at the bottom of the fuel filter, the fuei filte
alarm lamp on the control panel (optional) will light up. (4LHA-HTP/-HTZP)

(4) Inspection of Battery
Fire due to Electric Short-Circuits
Always turn off the battery switch or detach the earth cable (-) before
inspecting the electrical system. Failure to do so could cause short-
circuiting and fires.
Proper Ventilation of the Battery Area
Be sure the area around the battery is well-ventilated and there is
nothing which could start a fire. During operation and charging, hydrogen
gas is emitted from the battery and can be easily ignited.
Battery Fluid
Battery fluid is diluted sulfuric acid. It can blind you if it gets in your
eyes, or burn your skin. Keep the fluid away from your body. Wash it off
immediately with a large quantity of fresh water if you get any on you.
