CONTROL OWNING AND OPERATING COSTS
Customer Personal Service (CPS) is part of John Deere’s proactive, fix-before-fail
strategy on machine maintenance that will help control costs, increase profits, and
reduce stress . Included in this comprehensive lineup of ongoing programs and ser-
vices are:
Fluid analysis program – tells you what’s going on inside all of your machine’s
major components so you’ll know if there’s a problem before you see a decline in
performance . Fluid analysis is included in most extended coverage and preventive-
maintenance agreements .
Component life-cycle data – gives you vital information on the projected life
span of components and lets you make informed decisions on machine maintenance
by telling you approximately how many hours of use you can expect from an
engine, transmission, or hydraulic pump . This information can be used to preempt
catastrophic downtime by servicing major components at about 80 percent of
their life cycle .
Preventive Maintenance (PM) agreements – give you a fixed cost for main-
taining a machine for a given period of time . They also help you avoid downtime
by ensuring that critical maintenance work gets done right and on schedule . On-
site preventive maintenance service performed where and when you need it helps
protect you from the expense of catastrophic failures and lets you avoid waste-
disposal hassles .
Extended coverage – gives you a fixed cost for machine repairs for a given
period of time so you can effectively manage costs . Whether you work in a severe-
service setting or just want to spread the risk of doing business, this is a great
way to custom-fit coverage for your operation . And an extended coverage contract
also travels well because it’s backed by John Deere and is honored by all Deere
construction dealers .
Customer Support Advisors (CSAs) – Deere believes the CSA program lends
a personal quality to Customer Personal Service (CPS) . Certified CSAs have the
knowledge and skills for helping make important decisions on machine mainte-
nance and repair . Their mission is to help you implement a plan that’s right for
your business and take the burden of machine maintenance off your shoulders .
