	* A reservoir should have baffles that force the liquid to take a twisted path and be large enough to hold 2 to 3 minutes of maximum pump flow, with room to spare.		* A reservoir should have baffles that force the liquid to take a twisted path and be large enough to hold 2 to 3 minutes of maximum pump flow, with room to spare.
	* Fluid contamination is marked by oxidation, gummy deposits, sludge, bubbles and noise. Not to mention premature wear and/or failure.		* Fluid contamination is marked by oxidation, gummy deposits, sludge, bubbles and noise. Not to mention premature wear and/or failure.
			* If operating in noticeably dusty conditions the system should have heavy duty breathers and chrome plated piston rods.

			===Fluid/Oil===
			* Fluid and filter replacement schedules should be determined by having the fluid tested periodically.
			* Viscosity should probably be changed in spring and fall.
			* To drain the fluid, run the system to get it hot, then drain from the lowest point.
			* Use a light viscosity fluid with a rust inhibitor to flush out deposits.
			* When adding fluid, use a 25 micron filter or a 200 mesh metal screen.
			* If the system becomes dramatically contaminated then drain and clean the reservoir, inspect all valves, cylinders, lines and hoses for wear and/or particles, flush all components, replace filters, dispose of the contaminated fluid. Change filters after 50 hours of operation on clean fluid.

	* Malleable iron, "...a material which has properties about half way between those of steel and of cast iron. Its chief virtue is its ability to resist repeated shock...Malleable castings are widely used in small castings such as those used in locks...and gun parts, the process is especially effective because decarbonization is more complete than in parts which have thick sections...Malleable castings should not be welded...However, malleable castings can be successfully brazed, or soldered with hard solder or brass."
	* Annealed gray iron, "...is extensively used in vise castings and to replace malleable iron in farm machinery. It can be made much more rapidly than malleable iron, and in some ways is superior to it...[it can] stand much bending and possess many of the properties of a mild steel."
	* Wrought iron, "...it is easily welded on the anvil or with a torch. It can be shaped and bent into intricate forms. It differs from mild steel chiefly in the fact that it contains evenly diffused slag...Wrought iron does not become fluid, so it cannot be used for casting."
	* Steel, "If all the carbon and impurities are removed from cast iron and then an amount of carbon up to 2 per cent added in such a way that it combines with the iron, steel will be produced...This steel of low-carbon content is the steel used in building bridges and making the frames of skyscrapers. It can be forged, rolled, or welded. If more carbon is added, the steel takes on a new property; it can then be made very hard by heating it to red heat and cooling it quickly. It is then called tool steel. This is the steel used for making files, chisels, and cutting tools. It has a remarkable property in that after it has been hardened it can be tempered to intermediate degrees of hardness...Tool steel, because of its properties, has become one of the most useful materials employed in industry. It can be annealed so that it is easy to work with files or other metal-cutting tools."		* Steel, "If all the carbon and impurities are removed from cast iron and then an amount of carbon up to 2 per cent added in such a way that it combines with the iron, steel will be produced...This steel of low-carbon content is the steel used in building bridges and making the frames of skyscrapers.

	* Zinc, "zinc's most common use is as an alloy of copper and aluminum. We seldom make things of solid zinc, but it can be cast and soldered. It is used in its sheet form for lining tanks and for roofing."
	* Lead, "It is easy to cut and shape. It is generally joined by a process which has come to be called lead burning, but is really welding. Lead is also added to brass as an alloy to make the brass machine easily, and it is alloyed with tin to make soft solder."
	* Tin, "...is used extensively to coat steel; tin cans, for example, are really tin-coated steel cans. We have just mentioned the use of tin in combination with lead to make solder. It alloys with copper to form bronze."
