CONTROL OWNING AND OPERATING COSTS
Customer Personal Service (CPS) is part of John Deere’s proactive, fix-before-fail strat-
egy on machine maintenance that will help control costs, increase profits, and reduce
stress. Included in this comprehensive lineup of ongoing programs and services 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 maintain-
ing a machine for a given period of time. They also help you avoid downtime by ensur-
ing 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 construc-
tion dealers.
Customer Support Advisors (CSAs) – Deere believes the CSA program lends
a personal quality to Customer Personal Service (CPS). Certified CSAs have the knowl-
edge and skills for helping make important decisions on machine maintenance 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.
