Generator Servicing & Maintenance in Perth

Dependable Service for Continuous Power

At Ozwide Power, we service, maintain and repair generators across Perth — from industrial and building standby sets in Kewdale, Welshpool, Kwinana, Henderson, Canning Vale, Malaga, Osborne Park, Wangara and the Perth CBD, to home and property backup generators in suburbs like Stirling, Ellenbrook, Canning Vale and Baldivis. Whether you run a single standby unit or manage a fleet of critical power assets, our Perth-based technicians come to you.

Using OEM-approved service procedures and genuine parts, we inspect, test and service all major generator and engine brands — Caterpillar (Cat), Cummins, Kohler (SDMO), Denyo, Kubota, Yanmar, Perkins, FPT, PowerLink, Atlas Copco, Pramac, Generac, Gentech and Dunlite. Every visit ends with a digital service report covering hour readings, findings and recommendations — available in your customer online portal alongside your schedule and any remedial quotes — so you have the records your insurer, auditor or building manager asks for.

From scheduled 250, 500 and 1,000-hour servicing and fixed-price preventative maintenance agreements to fault diagnosis, load bank testing and breakdown support, we look after generators for manufacturing, logistics, mining, telecommunications, healthcare, government and residential customers. Metro sites are our core; the Peel region, South West, Wheatbelt and Mid West are covered by arrangement.

WE'RE TRUSTED ACROSS WA

We're a proud Australian company delivering industrial power generator solutions to customers across Perth and Western Australia. As a dedicated WA service provider, we put customer service first — offering products with useful innovations, smart technical advice, and solid aftermarket service and repairs. We're not about being the biggest name around, just the one you can count on.

Generator Brands We Service

Our technicians are experienced across the brands that power Australian industry, agriculture and homes. If yours isn't listed, ask — we service any make.

Heavy industrial, mining & critical power

  • Caterpillar (Cat) — the benchmark for heavy mining and civil construction, backed locally by WesTrac; large-kVA prime and standby sets.
  • Cummins — dominant in healthcare, data centres and major infrastructure for its transient load response and local engineering support.
  • Kohler Energy (formerly SDMO) — widely specified in commercial buildings and industrial complexes for advanced control systems and premium build quality.
  • Denyo — the Japanese brand favoured by hire fleets for being quiet, reliable and near-indestructible on harsh construction sites.

Diesel engines behind agricultural, remote & mid-tier industrial sets

  • Kubota — the standard for sub-50 kVA industrial power in rural WA; fuel-efficient continuous operation in dusty conditions.
  • Yanmar — durable, compact diesel generators and pump sets used across agriculture and marine.
  • Perkins — the engine inside a large share of Australia's mid-tier industrial generators; long service intervals and strong local parts availability. Ozwide Power is a Perkins OEM dealer.
  • Volvo Penta — heavy-duty engines behind many 100–600 kVA Pramac and packaged sets. Ozwide Power is a Volvo OEM dealer.
  • FPT (Fiat Powertrain) — heavy-duty, efficient diesel power packs increasingly found in large irrigation and standby units.

Packaged generator builders & Australian integrators

  • Pramac — heavy-duty commercial and industrial generators on Perkins, Yanmar, Cummins and Volvo engines, deployed for commercial backup and manufacturing plants nationwide. Ozwide Power is a Pramac Authorised Dealer, and a Perkins and Volvo OEM dealer.
  • Generac — home standby and light commercial sets; we sell and service the range.
  • PowerLink — high-volume, competitively priced, mine-spec compliant diesel generators common on WA worksites.
  • Atlas Copco — robust, highly mobile rental-spec generators built for outback towing and weather.
  • Gentech / Dunlite — Australian-built industrial, agricultural and mine-spec generators on Honda, Yamaha and Kubota engines.

What Does a Generator Service Include?

A generator service is a routine inspection, test and replacement of wear items that keeps the unit safe, reliable and ready to start. It's preventative: the point is to find the flat battery, blocked filter or contaminated fuel before a power outage does. A standard Ozwide Power service covers:

  • Engine oil and filter change using the manufacturer's specified grade to protect against wear and extend engine life.
  • Air filter service or replacement to keep combustion efficient and dust out of the engine — critical in WA conditions.
  • Fuel filter replacement and fuel system inspection, checking for water, contamination and diesel bug in tanks that have sat idle.
  • Battery load test and charging system check — the single most common cause of a no-start.
  • Cooling system inspection: coolant level and condition, hoses, belts, radiator and fan.
  • Control panel, alarm and safety shutdown verification to confirm monitoring and protection functions operate correctly.
  • Transfer switch / changeover test on standby installations to confirm the unit picks up load when the mains drop.
  • Test run under load with voltage, frequency and temperature recorded.
  • Digital service report emailed after the visit with hour reading, findings, photos and what's due at the next interval.
  • Customer online portal access to monitor your service schedule, download reports and review remedial quotes.
  • Fluid sampling by an independent laboratory (optional) — oil, coolant and fuel analysis to detect wear and contamination early.

How Often Should a Generator Be Serviced?

  • Standby / emergency sets (run rarely): full service every 12 months, plus a monthly no-load test run and a quarterly run under load.
  • Prime / continuous power: every 250–500 running hours — check your engine manual, as Perkins, Kubota, Yanmar and Cummins intervals differ.
  • Portable and job-site sets: every 100 hours or annually, whichever comes first.
  • All diesel units: fuel polishing every 12–24 months if the fuel sits unused — stale diesel is the leading cause of standby failure in WA's heat.

Why Generator Maintenance Matters

  • Extends equipment life by catching wear and contamination before they cause major failures.
  • Reduces unexpected breakdowns and expensive emergency callouts.
  • Ensures the unit starts and carries load during a mains outage — when it actually counts.
  • Maintains fuel efficiency and rated output.
  • Keeps the manufacturer's warranty valid and supports compliance with Australian standards.
  • Protects the value of the asset and lowers total cost of ownership.

Preventative Maintenance Agreements

A generator that only runs when the mains fail needs to be maintained as if it runs every day. Ozwide Power Preventative Maintenance Agreements put your servicing on a fixed schedule at a fixed annual price, so the unit is inspected, tested and ready before it's needed — not after it's failed.

Each agreement is built around your equipment, running hours, how critical the load is and the manufacturer's service intervals. Visits can be monthly, quarterly, bi-annual or annual. A typical agreement includes:

  • Scheduled service visits — monthly, quarterly, bi-annual or annual to suit the site and how critical the load is; 250 / 500 / 1,000-hour intervals for prime-power units — booked in advance and around your operation.
  • Priority breakdown response — agreement customers go to the front of the queue when a unit goes down.
  • Parts pre-ordered — filters, belts and consumables are on hand for each visit, not waiting on freight.
  • Full service history on file — every report, hour reading and recommendation kept for warranty, insurance and compliance audits.
  • Customer online portal — log in any time to see upcoming scheduled visits, download digital service reports and review and approve remedial quotes.
  • Fluid sampling by an independent laboratory — oil, coolant and fuel samples analysed off-site to pick up wear metals, contamination and coolant breakdown before they cause a failure.
  • Load bank testing — optional annual test under load, recommended for building standby and life-safety sets.
  • Fuel condition checks — with diesel polishing scheduled when fuel has sat for 12 months or more.

Regular maintenance identifies wear and deterioration before it becomes a major repair, reduces downtime and callout costs, keeps your manufacturer's warranty valid and supports compliance with Australian standards.
