Introduction
The first of June, and winter is officially here. The mornings in the Bay of Plenty have that proper chill to them now, the days are short, and the rain is settling in for the season. Over the last couple of weeks we have talked about swapping your shed from summer to winter, and how to store the seasonal tools properly. So now that winter has actually arrived — what is the one job that matters most?
It is a fair question, because winter brings a long list of maintenance jobs and it is easy to feel like you should be doing all of them at once. But if you are short on time and you only get to one thing, there is a clear answer.
The most important thing to do in winter is this: deal with your fuel and get your gear serviced before the cold and damp do their damage. Everything else — storage, cleaning, sharpening — matters too, but fuel and servicing are what stand between you and a tool that simply will not start when you need it.
Why fuel is the number one winter job
Ask any small-engine technician what kills more tools over winter than anything else, and the answer is fuel. Not frost, not cold — fuel.
Petrol does not cope well with sitting still. Over the weeks of a winter layup it starts to break down, separate and absorb moisture from the damp Bay of Plenty air. The result is gum and varnish in the carburettor, a fuel system that no longer flows properly, and a tool that turns over but will not fire. By the time you discover the problem, the fix is often a carburettor clean or rebuild rather than a five-minute job.
What "dealing with the fuel" actually means
- For tools you are storing: run the tank dry, or fill it and add a fuel stabiliser so the petrol stays usable
- For two-stroke tools: only ever store with fresh, correctly mixed fuel — old mix separates and absorbs water fastest of all
- For year-round tools like the chainsaw: keep fresh fuel on hand and avoid letting a part-used tank sit for weeks between jobs
- Never leave stale, untreated petrol sitting in a tank or carburettor over winter
Get this one thing right and you have avoided the single most common — and most expensive — winter breakdown.
A close second: the winter service
If fuel is the job you must not skip, a winter service is the job that covers everything else in one go. This is the time of year our workshop fills up, and for good reason. A service before or during the cold season means your gear is protected against the things winter throws at it, and ready the moment you need it.
What a winter service covers
- Fuel system cleaning and carburettor adjustment, so nothing gums up
- Fresh oil and filters, protecting the engine internals from corrosion
- Chain, bar and blade care — sharpening, tensioning and replacing worn parts
- Electrical and battery checks on battery-powered equipment
- Safety feature testing, including chain brakes and guards
- A full lubrication and clean of moving parts that moisture would otherwise attack
Booking this in now means you are not joining the queue in spring when everyone else suddenly remembers their mower.
Do not forget the firewood gear
Winter is firewood season, and your chainsaw is about to become the hardest-working tool you own. Between cutting and splitting for the fire and clearing branches after winter storms, it does not get the rest the summer tools do — which makes keeping it in top shape part of that "most important job."
- Sharpen the chain — a sharp chain cuts faster, safer and with less strain on the saw
- Check the tension before every session
- Keep fresh fuel and bar oil on hand so you are never tempted to run it dry or low
- Service it now if it has been sitting since last winter
A chainsaw that is ready to go turns firewood duty into a quick job. One that is dull, badly fuelled or unserviced turns it into a struggle — and a safety risk.
Work warm, dry and safe
One last thing that is easy to overlook: winter jobs happen in colder, wetter, lower-light conditions, and that changes how you should approach them.
- Wear the right gear — warm, dry, and with proper protective equipment for the job
- Let cold tools warm up briefly before working them hard
- Work in good light — winter days are short, so do not push jobs into the dusk
- Take your time — cold hands and slippery surfaces are exactly when accidents happen
Looking after yourself is as much a part of winter readiness as looking after the gear.
The one job, in a sentence
If you take nothing else from this: sort your fuel and book a service. Everything else — storage, cleaning, sharpening, the right wet-weather gear — builds on that foundation, but those two steps are what keep your tools alive through a New Zealand winter and ready for the firewood and cleanup jobs that define the season.
Welcome winter on your terms. A tool with sorted fuel and a fresh service does not care how cold the morning is — it just starts. That is the whole point.
The STIHL-certified team at STIHL SHOP Tauranga is here to help you get there. Book a winter service, talk to us about your fuel and storage, and head into the cold season knowing your gear is ready. There is no better time than the first week of winter to get it sorted.
