I have a s185 every time I start the machine in the morning it starts right up.If I am using it and shut it down It will crank but won't start unless it sits for 30 min or longer.Also I did notice when I turn key the counter for the glow plugs doesn't come on.But it is in the 80's where I live so maybe the glow plugs don't need to come on.Any help would be appreiated
