Load Banking

When a generator is lightly loaded for an extended period, a condition known as wet stacking can occur within the engine and after treatment system, resulting in a reduction of load acceptance and total power output. To recover a diesel engine from a wet-stacked condition, it must undergo increasing levels of load up to the full rated output until the symptom resides. Our field support team is equipped with industrial load banks and can dispatch to your location to service fleets of all sizes.

Engine Diagnostics

Today’s technologically advanced equipment may require specialized tools and technicians that can interpret, resolve, and clear alarm codes and faults. The costs of diagnostic equipment and labor can be quite high. Generac Mobile’s team of qualified field service technicians can dispatch to locations and provide on-site diagnostics, reducing travel and shipping costs along with reducing the total amount of down time.

Service Regeneration

Interim and Final Tier 4 diesel generators with a DPF after treatment have the capability to passively and actively regenerate the system to reduce soot and ash levels. However, all too often customers find themselves beyond the point of no return resulting in service regeneration; required to remove a 50% de-rated condition. While taking the unit to an engine service dealer is an option, Generac Mobile technicians can dispatch to locations and provide on-site assistance.

Equipment Refurbishment

As equipment in your fleet ages, it becomes less efficient and may stop working altogether. Maximize your investment by having Generac Mobile technical service experts review your current equipment, recommend repairs and upgrades and conduct factory-certified refurbishment to extend the service life of your equipment. For certain equipment, refurbishment can greatly reduce expenses by extending the life of your existing Fleet.

Service Contracts

No matter the size or location of your mobile equipment, Generac Mobile can work with our servicing dealer network to identify a custom solution that will fit your unique needs.

Downline Support

Fleet managers can see large influxes of down equipment during peak rental seasons. Instead of leaving assets frozen on the deadline, our team of factory trained support representatives can work with customers from the job site to the corporate office to get your fleet back up and running.

Delivery Inspection

All Generac Mobile equipment is factory tested prior to delivery to the customer. However, there are still activities required on-site to get the equipment jobsite ready. This includes assessing the equipment condition for shipping damage, filling and verifying fluid levels, deploying the tow hitch, performing initial startup and green-tagging the equipment for rental. Trust our factory-trained technicians to provide on-site inspection, providing you with an additional level of confidence and peace of mind before deploying equipment to the jobsite.

Technical Training

Generac Mobile offers customized training for your equipment.

Level 1: Generac Mobile offers field based level 1 technician training at the customer’s location. This training level is required for any level of servicing dealer. Time, date, and location are coordinated between the customer and a factory representative.

Level 2: While level 1 training is often comprehensive enough for most rental dealers, some customers may want a more comprehensive dedicated training course. The level 2 training is three-day factory course held at the Generac Training Center in Eagle, WI. Courses are scheduled throughout the year.
