A. Improper use of injector by filling boiler at a rapid rate when
drifting or standing in a siding, unless you have a heavy bright fire to
heat the injected water to the boiler temperature as fast as it comes
into the boiler. Excessive use of the blower, especially with a light
fire or when cleaning the fire. Improper attention to machinery, such as
keeping parts not properly lubricated, rods not properly keyed, wedges
not adjusted, carrying too much or too little water in the boiler,
working water through the cylinders, allowing engine to slip
unnecessarily, use of sand on one rail only or otherwise improperly;
being careless in any way where care is required and not properly
reporting the necessary work so it can be done promptly.
