Preventive maintenance plan: a schedule that actually happens
Build a preventive maintenance plan people follow: service by date and by meter reading, add time limits, plan with estimated dates and track the costs.
The short answer
Base each service on a date, a meter reading or both, and always add a time limit so an idle machine is still checked. Put everything due in one list, review it on a fixed day, and record each service with its cost.
Why do maintenance plans fail?
Plans rarely fail because people do not care. They fail for simple reasons:
- The schedule lives in one person's head, or on a wall chart that nobody updates.
- Reminders sit in private calendars, so they leave with the person.
- Intervals ignore how hard each machine really works.
- When a job is done, nobody writes down what was done or what it cost.
A plan that actually happens closes those gaps. Every machine or vehicle has one record that holds its schedule and its history. Each service is due by date, by meter reading, or both. There is one list of what is due, with one owner. Preventive maintenance means servicing before something breaks, and the plan turns that intention into a habit.
Should you service by date or by meter reading?
Use a meter when wear follows use, and a date when things age with time. A meter is any counter of use, such as engine hours, kilometres or printed pages. Most machines and vehicles need both.
| Trigger | Best for | Examples | Weak spot |
|---|---|---|---|
| Date only | Checks required at set times, and parts that age | Fire extinguisher checks, safety inspections, calibration | Ignores how hard the item works |
| Meter only | Wear that follows use | Oil changes by engine hours, servicing by kilometres | An idle machine never comes due |
| Meter with a time limit | Most engines, vehicles and machines | A 500-hour service, or once a year if that comes first | Needs regular readings |
Start from the maker's manual. It gives the intervals the maker expects, and often both a meter limit and a time limit. Where the manual says nothing, ask the dealer or your workshop what they use.
What is a time backstop, and why do you need one?
A backstop is a time limit that applies even when the meter says a service is not due yet. It protects you in two ways.
First, some wear does not need use. Oil and coolant age, rubber seals dry out and batteries go flat while a machine stands in the yard. Second, a meter plan depends on readings. If nobody logs the hours for a while, the date still brings the machine back into view.
In TagOrbit, a time limit always applies as well as the meter. A service still comes due when the readings stop.
How do estimated dates help you plan?
A meter tells you how far away a service is, but not when it will happen. To book a workshop slot or order parts, you need a date.
You can work one out from the pace of use. Divide the hours left by the hours used per week, and you know roughly how many weeks remain. When the pace changes, the date moves, so regular readings keep it close to reality.
Treat an estimate as an estimate. Show it as one, and keep the reading it came from next to it, so nobody mistakes a forecast for a promise.
In TagOrbit this happens on its own once you log readings. TagOrbit learns the pace of use and moves service dates with it. Each estimated date is labelled "estimated" and names the reading it came from. For engine hours on building sites, read the guide to tracking machines, hours and fuel.
Where do you start if you have no service history?
You will probably start with gaps. Some machines have a full service book, and others have nothing at all. Do not wait for perfect data before you begin.
Take a reading from every meter today. Then find the last service date wherever you can: the service book, old invoices or the workshop's own files. Where nothing is known, plan a first service soon, starting with the machines that work hardest or matter most for safety. From that service on, every interval counts from a known point.
How do you make sure the work actually gets done?
Put everything that is due in one list, and give that list an owner. Several lists mean several places to forget.
In TagOrbit that list is called Needs attention. It collects due dates, meter-based services, low stock and more, most urgent first, with Done and Snooze on each row. Each alert appears inside the application, so opening the list has to be part of someone's routine.
A weekly routine keeps the plan alive:
- Log the meter readings on the same day each week.
- Open the list of what is due and start at the top.
- For each job due soon, book the workshop or give the job to a named person.
- Order the parts the job needs, before the day.
- When the work is finished, write the service down with its cost.
- Mark the row Done. Snooze it only when you have a real new date.
Never snooze a safety inspection without a written reason. A snooze should move a job, not hide it.
What should a service record contain?
A service record is the memory of your plan. Without it, you cannot show that a check happened, and you lose the cost history.
Write down at least:
- the date, and the meter reading at the time;
- what was done, and which parts were used;
- who did it: your own fitter, a workshop or a vendor;
- what it cost, with parts and labour apart if you can;
- anything found that needs a follow-up job.
In TagOrbit you record services and repairs with stages, the workshop or vendor and the cost. Every change keeps its before and after, with who made it and when. Each record's Story tab shows its full timeline, so a machine's whole service history sits in one place.
How do you use the cost of ownership?
Cost of ownership is what an item really costs you over its life: the purchase price plus every service and repair. It helps you decide, with numbers, when to repair and when to replace.
Compare similar machines side by side. When one costs clearly more to keep running than the others, look at why. Sometimes an operator needs training. Sometimes the machine is simply worn out.
In TagOrbit, service and repair costs add up into each item's total cost of ownership. A report can take services as its source, group them, and show subtotals per group and a grand total. You can export it to CSV, Excel or PDF, or print it for the meeting where you decide.
Where does TagOrbit fit?
TagOrbit keeps the plan and its history in one place: dates, meter readings, time limits, estimated dates, Needs attention and service records. It runs in the browser on computers, tablets and phones, so readings can be logged where the machine stands. Every feature is included in one price, shown on the TagOrbit pricing page.
