Generator set maintenance: the complete guide

A generator set only proves its worth when you need it most: during a power cut. That is why maintenance isn't an expense, it's an insurance policy. In this guide we sum up what we see every day in the workshop.

How often should maintenance be carried out?

As a general rule, an annual service for standby units in occasional use, and six-monthly servicing or running-hours-based servicing for units that work frequently. A set that doesn't start for years builds up silent problems: sulfated batteries, degraded fuel, dried-out seals.

What a proper service includes

• Oil and filter change (oil, fuel, air).
• Battery condition and charge.
• Coolant and cooling circuit.
• Automatic start test and load test.
• Inspection of belts, hoses and leaks.
• Cleaning and check of the control panel.

The load test: what many people forget

Starting the set with no load doesn't prove it will work when you need it. The load test confirms it delivers its true power output and prevents wet stacking (unburnt fuel) in diesel engines.

Warning signs

Excessive smoke, hard starting, new noises, leaks or a panel flagging faults: don't wait for the blackout. A timely service costs a fraction of an emergency repair.

Maintenance contract

For businesses, the marine sector and industry, a tailored contract ensures regular servicing, 24/7 priority and, in many cases, a discount on spare parts. At GEYMO we tailor it to how critical your installation is.
