-A '''screw pump''' is a small [[building]] that can lift liquids ([[water]] or [[magma]]) from one level below onto the same [[Z-level]] as the pump. It is two tiles by one tile in size, and it can be either manually operated by a [[dwarf]] with the [[pump operator]] job or by using [[gear assembly|gear assemblies]] connected to [[water wheel]]s and/or [[windmill]]s.
+A '''screw pump''' is a small [[building]] that can lift liquids ([[water]] or [[magma]]) from one level below onto the same [[Z-level]] as the pump. It is two tiles by one tile in size, and it can be either manually operated by a [[dwarf]] with the [[pump operator]] job or by being [[power]]ed by [[water wheel]]s and/or [[windmill]]s.
 The direction you want the fluid to travel must be chosen at the time of construction.  Pumping only occurs in a straight line, and involves a total of 4 tiles in a row - the liquid source, two for the pump, and the output. The "rise" in levels occurs on the first tile, the intake side, from one level below up to the level of the pump*.  Pumped fluids can and will flow immediately after being pumped, as normal for that fluid.  Pumped fluids will have a [[pressure]] equal to the exit [[z-level]] - a pump never "forces" water to a higher [[z-level]] than the output tile.

 * Pumps can also be used in conjunction with a [[water wheel]] or a [[windmill]] to become self-powered.
 * Active mechanisms connected to the pump will automatically start the pump; to prevent this either restrict liquid flow using floodgates or hatches, or put in a [[gear assembly]] linked to a [[lever]] to disconnect the [[power]].
-* Adjacent pumps ''automatically'' transfer mechanical power to any other adjacent pump(s), no [[axle]] or [[mechanism]] is required.  If too many pumps are adjacent, there may be insufficient power to power them.
+* Adjacent pumps ''automatically'' transfer mechanical power to any other adjacent pump(s), no [[axle]] or [[mechanism]] is required.  If too many pumps are adjacent, there may be insufficient power to run them. This does '''not''' apply to pumps being manually operated by dwarves.
 * A hatch above the input tile (on the same level as the pump) that is linked to a trigger (a [[lever]] or [[pressure plate]]) makes an effective on/off switch for that pump.
 * In order to build pumps in a "hanging" state, as in the stacked screw pump example (below), one of its tiles must be able to connect to a nearby machine, either already existing or designated to be built. If, when the screw pump's construction is completed, the supporting mechanism has not yet been completed, it will promptly collapse into its component parts.

 * Pumps do '''not''' push liquids '''up''' additional Z-levels above them.  They only deliver water to their own level.  That is, if you direct the output of a screw pump into a 1-square space surrounded by walls, the water will not "overflow" the walls. Consequently, a pump will refuse to move liquid if the level it is pumping to is completely filled.  Higher levels can be achieved using a "pump stack" (below). (See [[Pressure]])
-* In order to safely pump magma, you do not need to build a pump out of [[magma-safe]] materials, unless the open tile is going to be submerged in magma.
+* In order to safely pump magma, the pump must be made of [[magma-safe]] materials or the pump's components will melt or burn. Curiously, if the [[pipe segment]] is made of any [[metal]], then none of the pump's components will heat up, allowing a wooden corkscrew to pump magma without problems. This is likely a bug.
 * Magma, which normally has no pressure, will behave like pressurized when pumped. For example, when pumped into an U-turn, magma will come out at the other end. Normal (non-pumped) magma would just pool at the lowest level. This may be either very useful (can be used to build pressure towers for magma) or deadly (forge level flooded with magma, because someone tried to pump magma into a volcano).
 * Pump's pseudo-pressure doesn't work across diagonals. If there is a diagonal-only passage in your tunnel, liquids will seep slowly through it, instead of bursting through above their normal maximal speed, like they would if there was good passage.

 # If you thought ahead, you should only need one axle to connect the surface gear to the pump. A pump can be powered from any side.
-I recommend that you connect a lever to one of your gears beforehand. The pump will start pumping as soon as it has power.

 You can change stuff around as the situation dictates, but that should get you started.
