4.7SCHEDULED MAINTENANCE

The following is a recommended maintenance schedule for Generac Guardian small standby and residential gen- erator sets. The established intervals in the schedule are the maximum recommended when the unit is used in an average service application. They will need to be decreased (performed more frequently) if the unit is used in a severe application. Use the unit hour meter or calendar time, whichever occurs first, from the previous mainte- nance interval to determine the next required maintenance interval.

Service Maintenance Interval Information:

The various service maintenance intervals are designated by interval numbers as follows:

1An early inspection of the generator set to insure it is ready to operate when required and to identify any poten- tial problem areas.

Performed monthly or following each 10 hours of operation of the unit and requires approximately .5 man- hours per unit to complete.

This inspection may be performed by the end user providing the following safety steps are taken to prevent the engine from starting automatically without warning:

To prevent injury, perform the following steps in the order indicated before starting any maintenance:

•Disable the generator set from starting and/or connecting to the load by setting the control panel AUTO-OFF-MANUAL switch to the OFF position.

•Remove the control panel fuse.

•Turn off utility supply to engine water heater.

•Turn off the battery charger by turning off utility supply to the transfer switch.

•Remove the negative battery cable.

The battery charger must be turned off BEFORE removing the battery cable to prevent an over current condi- tion from burning out sensitive control panel components and circuits.

Following all maintenance, reverse these steps to insure the unit is returned to standby setup for normal operation when required.

2A break-in service inspection of the generator set to insure it is ready to operate and carry the load when required, and to identify any potential problem areas.

Performed ONLY ONCE following the first three months or the first 30 hours of operation after purchase of the unit and requires approximately 2.5 man-hours per unit to complete.

This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge to accomplish and should be performed only by an authorized Generac Service Dealer.

3An operational inspection of the generator set to insure it is ready to operate and carry the load when required, and to identify any potential problem areas.

Performed semi-annually or following each 50 hours of operation of the unit and requires approximately 1.5 man-hours per unit to complete.

This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge to accomplish and should be performed only by an authorized Generac Service Dealer.

4A mid-level inspection of the generator set to insure it is ready to operate and carry the load when required, and to identify any potential problem areas.

Performed annually or following each 100 hours of operation of the unit and requires approximately 4.0 man-hours per unit to complete.

This inspection contains some maintenance tasks which require special tools, equipment, and/or knowledge to accomplish and should be performed only by an authorized Generac Service Dealer.

One of the standout features of these models is the use of Generac’s G-Force Engine, specifically designed for reliability and longevity. This engine is notorious for its durability, capable of handling demanding workloads and proving to be more efficient than typical engines found in similar generators. It provides quick start times, lower emissions, and is built to withstand extended operational cycles.

Another notable technology in these models is the Quiet-Test™ mode, which enables the generator to run at a lower RPM while it performs an exercise routine. This feature not only reduces noise during operation but also conserves fuel, making it an eco-friendly option that doesn’t compromise on performance.

The generators are equipped with advanced monitoring and control features, including the Mobile Link™ application compatibility. This allows users to monitor the status of their generator remotely via a smartphone or tablet, offering peace of mind and real-time access to the generator's operational functioning. This connectivity also enables the user to receive alerts and notifications about maintenance needs or when the generator is in need of attention.

In terms of design, these models boast a robust steel enclosure that offers superior protection against the elements, thereby enhancing durability and ensuring efficient operation regardless of weather conditions. The enclosures also come with a weather-resistant finish, making them suitable for outdoor installation.

Moreover, the generators feature a well-thought-out installation process with easily accessible controls and noise-reduction technology, which helps minimize disturbances for residential applications. They also offer multiple power outputs, catering to varied energy needs, from essential home appliances to larger devices.
