EQUIPMENT MAINTENANCE

Offsite Sweeping LLC’s approach for equipment maintenance begins with our maintenance staff.

Currently, we have seven full-time mechanics with over ten years’ experience each. We have in-house metal fabrication and welding shop so that we can accelerate any structural repairs. These repairs range from fixing a hinge on a large debris truck to completely overhauling a sweeper’s elevator or hopper system. We have found this to be an extremely valuable asset to our operation, as quickly getting the parts necessary to have operational equipment on the road is one of the most challenging aspects for any sweeping company. The ability to keep most of that work in-house is crucial to our success. We have an additional six employees who assist in the shop, and with servicing and staging equipment for the next shift. Before and after every sweeper operator or large debris truck operator completes a shift, a pre-trip and a post-trip inspection report is completed and turned into the shop.

The shop mechanics review these inspection reports daily and make all necessary repairs prior to the equipment hitting the road again.

Our centralized headquarters located at 2113 E Jackson Street, Phoenix, AZ 85034 encompasses roughly

3 acres including a 25,000 square foot shop with 8 repair bays, washout and refueling area, along with space for debris dumping and dirt screening. We have an extremely large investment of parts in stock on our shelves covering almost every replacement part available, as minimizing lead time for parts that could extend equipment downtime is very crucial. We have systems in place where every sweeper and debris truck rolls through the shop for a mechanic’s inspection prior to being cleared for the next shift. In addition to daily inspections, we have routine maintenance schedules for all equipment. Most major repairs including engine rebuilds, transmission replacements, drivelines, and all things hydraulic are also completed at our shop. When we have sweeper systems that need repair, those repairs are also taken care of at our shop unless we run into unsolvable complications. On those rare occasions, we have many local service providers that we can source from. We have built great working relationships with all of our suppliers and repair shop vendors which has helped move our needs to the top of their lists when necessary. Scenarios where trucks are taken to outside repair shops typically are due to internal transmission issues, problems with emissions reporting systems that we are unable to solve, or complicated electrical problems. Those situations require dedicated personnel with special software and knowledge. Our outside repair shop vendors are fully capable of those repairs when we call upon them to assist.

Time frame for specific major sweeper system repairs due to ware:

Sweeper Elevator Floor o The process to replace a sweeper elevator floor includes removing chains & flights, along with roller bars and sprockets. Then the floor sections are removed. Usually some of the bolts require a torch to get them removed. With the floor removed, we will repair any excessive damage to the elevator side walls, clean off the rails, and install the new floor pans. After installing the new floor pans, new sprockets are put on the rollers, new chains are installed, and flights are then attached. After confirmation of an operational elevator system, the rear broom is re-installed to complete the job. The turn-around for this job is about 2-days depending on the severity of repairs required to the elevator walls.

Flights and Chains / Conveyor System o The Nescon X-Broom, Elgin Broom Bear and Schwarze Avalanche Sweepers use flights and chains. Typically, we are able to remove existing flights and chains, string up new ones and get the truck operational within 1-day for this job. In the event a roller bar or sprockets needs replacement, we are most likely able to keep the repair down to a single day activity.

o The Elgin Eagle Sweeper uses a conveyer system. On occasion, the conveyer can get ripped and require replacement. The replacement of the conveyer is a 1-day job. We always stock a conveyer system for Elgin Eagle Sweepers when the

Elgin Eagle Sweeper is part of our fleet so that in the event one is needed, we don’t have to wait for it to be shipped to us. If the roller bars are required to be replaced, our staff can keep this repair down to a 1-day job.

Replacement of Water Tank o On occasion a sweeper’s water tank can get punctured due to excessive ware and vibrations that occur during normal operations. When that happens, water leaks out of the tank and limits the sweeper’s amount of time sweeping prior to needing to refill with water. To maintain efficient operations, water tanks need to be replaced when that happens. Our staff typically can remove and replace a water tank during a single 24-hour period or less.

The Offsite Sweeping repair shop’s ability to tackle critical repairs (Truck and Sweeper functions) as quickly as possible to get our equipment back on the road servicing our clients is an essential foundation to our underlying success. This attribute of our operation will continue through the duration of this contract.

Maintenance and Training Program:

We perform manufacturers’ suggested maintenance frequency cycles at our facility for all fluids and filters including oil, fuel, air, hydraulic, transmission, DPF, coolant, brakes, differential, wheel grease, etc. Daily checks of all filters and fluids are performed prior to sweepers and large debris trucks being staged for the next work shift.

At Offsite Sweeping, we are always looking for qualified personnel to help in the repair shop.

We have hired some mechanics right out of the local diesel schools, and other with years of experience at other shops. Upon hire, a new employee would start by learning our assembly line process on how we turn a truck from returning from a shift to being staged for its next sweep. That includes the washout, refueling, and servicing processes. Depending on previous experience, the employee may work as a “washout/service” personnel to continue the learning process. Some of the more experienced new hires would accelerate into the shop where they would have their own tools along with many shop tools available to assist with repairs. Supervision with some of the tenured mechanics allows new maintenance personnel to learn all aspects of repair jobs and get familiar with the individual pieces of equipment.

Seeing and doing the work alongside current mechanics who have been doing these repairs for many years has proven to be a valuable tool in further educating staff members. All of our existing shop mechanics have their own strengths, while one person may be better with electrical, another with engine building and another with air or hydraulic systems, we tend to lean on each other and work as a team to accomplish the tasks required to provide our services in a safe and efficient manner. With these processes in place every day is a new adventure where all mechanics can learn something new that will help them advance Offsite Sweeping forward. In addition to the staffing processes above, all repairs that are safety related including brakes, lights, and other items require two mechanics to verify completion prior to the equipment repaired to be cleared for the road. Our mechanics attend continuing education events to maintain all certifications that they have earned within their occupation.

We have had a great safety record due to this process, as rarely have we encountered any at-fault accidents due to equipment malfunctions.

Detailed day-to-day and periodic maintenance and service schedules:

Daily Maintenance for sweepers includes the list below. Replacement, repair, and replenishing fluids occur as needed daily.

o Verify all tires are inflated and lighting including arrow board functionality on sweeper and/or attenuator trailer.

o Empty hopper.

o Power-wash the entire truck, including elevator with flights and chains.

o Verify the length of main broom, gutter brooms, and drag shoe carbides.

o Verify presence of sweeper center divider.

o Check oil, transmission fluid, coolant, DEF, hydraulic fluid, and fuel levels.

o Grease all bearings on truck.

o Verify functionality of sweeper’s water system.

o Test all sweeping functions, if any deficiencies arise, notify shop mechanics so that the equipment can be repaired.

o Stage on street with attenuator trailer so that sweeper operator can perform pre-trip inspection prior to work shift.

Periodic Maintenance to be performed at intervals recommended by manufacturers.

o Oil Change including filters o Fuel filter change o Air filter change o Collant flush o Transmission fluid change o Hydraulic fluid filtering and changing o Chassis lubrication o Brake air-dryer diagnosis and change o Power steering filter and fluid change o Regen DPF system when notified, and on occasion to clear particulates o Additional maintenance to be performed as needed

The large debris trucks receive similar maintenance cycles based on frequency of use for the components that they possess. We check the lights and the water-tank pumps daily to ensure full functionality of those features.
