Importance of maintenance — monthly testing isn't optional

We have lost count of how many customers have called us in an outage with a generator that won't start. In almost every case, the unit hasn't been started in 6+ months. Batteries are flat, fuel has gone off, or coolant has degraded. None of these are expensive to prevent — but they all kill availability when it matters most.

01

Monthly self-test — what should happen automatically

Every standby generator with a DSE controller can be scheduled to crank, start, and run unloaded for 10–15 minutes weekly or monthly. The benefits: • Confirms the battery has enough capacity to crank • Circulates oil through the engine bearings • Warms the alternator windings (preventing moisture build-up that causes insulation breakdown) • Surfaces any fault codes BEFORE the real outage
02

Why monthly isn't enough on its own

A 10-minute unloaded run does nothing for wet stacking, fuel-filter blocking, coolant degradation, or alternator bearing wear. That's why a proper service plan also schedules: • Quarterly visual inspection (visual leak check, controller log download) • Annual oil + filter + coolant service • Annual load-bank test • Fuel-tank inspection every 24 months • Battery replacement every 4 years (max)
03

Beyond service life — warranty and insurance

Skipping scheduled maintenance voids most manufacturer warranties. Some insurance underwriters require proof of annual service for fire/business-interruption cover. Our stamped service reports satisfy both.

Oil/filter changes — yes, with care, and using OEM-spec parts. Load-bank testing and EPA / network compliance checks — no, requires accredited equipment and tickets. Warranty stamping requires an authorised service partner.
