Generator Boys offers a large variety of services to both industrial companies and the general public. We install new generators and also offer service and maintenance on all makes of generators. Maintenance contracts are also available depending on how often your generator is used. Our 24 hour call out service will make sure that your generators keep running, even when they are working under pressure. If there is a problem with your generator, we can do a fault finding analysis on all makes of generators.  

Servicing & Maintenance On All Makes Of Generators

Any generator set used for emergency or primary power supply must have periodic service and maintenance performed on it. Setting up a planned maintenance schedule, and performing all associated testing will insure generator availability on demand. The possibility of generator failures escalate when service and maintenance checks are not done.

Concept Of Planned Maintenance

Planned maintenance can be defined as performing service, maintenance, inspections and testing on a generator set on a pre-determined schedule. Each maintenance schedule should include inspections as stated on the listed below:

Visual Checks

Planned maintenance will define the checks to be completed at a certain time. Coolant, lubricating oil and coolant levels must be at specified levels, but these can be contaminated. When performing standard maintenance inspections look for the following:

Generator Refuelling Services From Generator Boys

Whether you own a small business or a large company, it is vitally important to have a back-up power system in place to take over during the event of a power outage. Failure to do so may result in major risks such as:

Because of diesel’s stability, reliability and cost efficiency diesel powered generators are more commonly relied on than generators powered by other fuels. It is because of this that they are the first choice back up power source for hospitals, farms, and industries that rely on information stored on an electronic database which can be compromised during a power outage.

Battery Failure

The single most frequent service call for generator failure is related to battery failure. Eighty percent of all battery failure is related to sulphation build-up — the accumulation of lead sulphates on the plates of lead-acid batteries.

Low Coolant Levels

The most obvious cause for a low coolant level is either an external or internal leak. Pay close attention to any visible puddles of coolant during inspections of the unit(s).

Oil Or Fuel, Leaks

Most often, apparent, oil leaks are not in fact leaks but the result of “wet stacking” (or “engine slobber”) caused by excessive no-load run time.

Controls Not In Auto

“Not in auto” messages are the direct result of human error. The obvious reason for “not in auto” situations is because the main control switch was left in the off position.

Air In The Fuel System

This is a common problem with newer generators that are not run on a regular basis. Closer tolerances within the fuel systems to meet today's emission requirements make fuel systems more susceptible to air affecting start-up.

Ran Out Of Fuel

Mechanical fuel level gauges may not always be accurate. Unlike a vehicle that is moving and using a higher percentage of its tank's capacity, a generator tank has no movement, causing the fuel to become stagnant.

High Fuel Level Alarm

High fuel level alarms are required by government regulations to prevent the overfilling of a fuel tank. The alarm should activate when the fuel tank reaches between 90% and 95% capacity.

Breaker Trip

First, verify that nobody has accidentally pushed a remote emergency stop switch.
If a breaker trips after the automatic transfer switch (ATS), the generator will not start. The status of the automatic transfer switch should be checked during a power outage. The ATS should have lights or a display showing the switch position and source availability. If you find a breaker tripped, make sure you can determine the cause of the trip prior to resetting.

On Site Load Testing Of Generators

The purpose of a generator is to offer a reliable source of power to your facility or commercial operation throughout an emergency, when power from the grid is unexpectedly lost, or is temporarily unavailable in your environment.
