Choosing the wrong tool can also overwork the user. For a given bit size and material, it takes more effort and strength to make a electric hole with a hammer drill than with a rotary hammer. This is a matter of weight motor distribution and leverage: With a rotary hammer, the heft of the tool itself provides much of the drilling force; hammer drills are much more dependent on pressure applied by the operator. This isn''t necessarily a problem for drilling an occasional hole or two, but for heavy repetitive use, a rotary hammer is the clear winner.

CPU systems are extremely stable and can be very energy efficient depending on duty cycle especially when combined with parallel LS circuits. Here, the duty cycle of a telehandler makes this very attractive. They feature a simple low-cost open center main valve converted to closed center with tailored spools and offer very good metering to minimize interference when multifunctioning.In the accompanying example, two separate valves art" used to control the functions. A 40 gpm valve is used for the boom up/down and retract/extend. A smaller 20 gpm valve is selected for tilt, frame level, left/right outriggers and auxiliary. An integrated circuit is affixed to the lower flow valve that provides load sense for the brakes, priority steering and pilot pressure. When the lift or telescopic function is activated the orifice is closed off and the pump goes to compensator pressure. It is also true for the tilt, frame level, outriggers and auxiliary functions. This is accomplished by sending the load sense signal through open center core of the 40 gpm valve on to the 20 gpm valve via power beyond. Since the pump in this example supplies only electric the flow requested any combination of valves is possible.
