jobsites operators can improve fuel efficiency Additionally Tier 4 Interim and Tier 4 engine technologies that use diesel oxidation catalysts and diesel particulate filters systems are highly effective at reducing particulate matter contained in excavator engine exhaust Its easier and more efficient for these systems to burn accumulated particulate matter when theyre being operated at a moderate rpm rather than idling The right operation Provide training for safe and proper operation of equipment Having a solid understanding of the various functions of an excavator not only increases productivity but it can avoid unnecessary accidents At the same time by providing hands on training operators can learn an excavators controls faster and distinguish which features will produce better results in certain applications Avoid excessive power Operators with an understanding of a machines various optimum power modes know they should avoid excessive power use Rather operators should set up the machine to deliver power that is adequate for their operation Likewise operators who properly maximize productivity put themselves in a position to protect engine systems and structural components from stress PIT STOP Establish machine limits Operators who are trained on the proper operation of an excavator develop a better understanding of a machines limits and the consequences for activities that push machines beyond rated capacities For example operators should lift only within rated tipping loads Operators should always lift squarely over the side or over the end of the machine If equipped they should select the digging mode on the excavator before using the machine for lifting work Strive for optimum sight lines Many manufacturers have addressed compromised sight lines with rear sloped hoods and re routed hydraulic hoses to increase visibility In addition to reducing component obstructions the cab designs of some manufacturers excavators provide windows that offer 360 degree visibility Being able to see a machines tracks the buckets sides and its many other attachments when digging is critical to an operator Maximizing an excavators life from the moment you purchase it can pay big dividends through increased productivity the reduction of maintenance surprises and safer more efficient operation P Q Debbie McClung is a technical writer for Two Rivers Marketing EDDY CURRENT SEPARATORS MAGNETIC HEAD PULLEYS DRUM MAGNETS OVERHEAD ELECTROMAGNETS ÈÇÓ ÇnÎäÊ ÊUÊ ÈÇÓ Ó Ê 8ÊUÊ777 www pitandquarry com March 2013 PIT QUARRY 85
