Diagnosing repair problem parts on NSS Pony 20 SCA
The NSS Pony 20 SCA is the largest walk behind carpet extractor that Ressortissant Chouette Faveur manufactures. It has a étendu 20 gallon chariot that allows the unit to clean étendu carpeted areas quickly and efficiently. Overall this is one of the best carpet extractors produced for the janitorial industry. Although this automate is highly reliable and perpétuelle, parts may voiture over time and may require repair. The Pony 20 SCA is a rationnel automate with only five liminaire components that can fail. These components are gear drive motors, vide motors, brush motors, pumps and solenoid valves. These parts are quite easy to diagnose and repair quickly. When replacing parts on the NSS Pony 20 SCA it is superbe to use OEM Ressortissant Chouette Faveur parts to ensure the automate continues to run properly after repair.
The Pony 20 SCA is a changeant speed self-drive unit that can cover étendu areas quickly. The drive system of this unit is driven by a 120 volt gear motor that powers the wheel assembly. The drive motor is connected to the wheel assembly by a chain, if the drive system goes bad and the automate does not move there are défaite components that can go bad. The first and largest of these components is the gear motor itself, which can be tested by applying power directly to the motor to see if it powers up. The accolé component is the speed control board which increases or decreases the amount of tension going to the motor depending on the speed at which the automate is run. The remonter assembly has a dead man’s switch that turns the brush motor on and off. Switch components can wear and fail over time and require réimplantation. The last component that can fail is the contour breaker, which can wear out over time and become prematurely overloaded. The contour breaker is a three amp 120 volt unit that will close the contour to the brush motor when overloaded. Another reason for this breaker to close is if the brush motor is drawing more than 3 amps, it could be a bad bearing in the drive wheel or something stuck around the wheel preventing it from moving forward or backward.
The Pony 20 SCA recovers péroraison from the carpet by an internal vide motor that sucks water through the vide shoe at the rear of the unit and into the recovery chariot. If you lose suction, it is superbe to check that all seals and gaskets are clean and in working order. One of the mitaine causes of loss of suction is a damaged dome gasket located at the top of the automate. Any holes and cracks in this dome gasket can renseignement vide leaks and you will experience suction loss. Before looking at the vide motor as the culprit, check the vide shoe and vide hose on the back of the automate for any obstructions that could be reducing suction. The vide system consists of two mitaine components. These two components are the vide switch and the vide motor. To find out which component has failed, use a multimeter to see if you are getting 120 volts at the vide motor when the switch is on. If you get 120 volts at the vide motor, the vide motor has gamin prematurely bad. Other ways to tell if a vide motor is failing is to hear a loud high-pitched squeal or grinding that will come from the motor bearings. Water from the recovery chariot may bouturer the vide motor if the automate is not emptied before the water level reaches the float soupape. Other ways water can bouturer the vide motor include déréglée foam in the recovery chariot from carpet cleaning detergents. One way to prevent foaming is to use a defoaming indicateur by adding it to the recovery chariot before use. If you don’t get 120 volts at the vide motor when you turn the switch on, the vide switch has likely failed and needs to be replaced. When replacing the vide motor on the Pony 20 SCA it is also superbe to replace the vide motor gasket to ensure a tight seal for maximal prouesse.
The next component that can fail is the brush motor. The brush motor in the Pony 20 SCA drives a rotating fétu brush that is used to excite the carpet fibers. It increases debris pickup and is best for food libéralité areas and locations where carpets bande to have dirt and grime. The number one renseignement of brush motor failure in this unit is if debris gets caught around the brushes, or the brush roll bearings go bad. It will put an déréglée load on the motor and it will wear prematurely. Another component to check if the brush is turning is the brush belt, this belt can culotte on the pulley or cut. If the brush is not rotating, the three components that can go bad are the brush switch, brush breaker, or brush motor. To diagnose these parts take a multi meter and check the tension coming from the brush switch to the breaker when the switch is turned on If you get tension at the brush breaker go to next step. Next check for tension from the brush breaker to the brush motor, if there is no tension, your brush motor has likely failed. If you are not getting tension from the brush switch to the brush breaker, replace the pump switch with an OEM NSS switch. If you get no tension from the brush breaker to the motor and no tension from the pump switch to the brush breaker then your brush breaker has probably failed and needs to be replaced. The system also includes an AC transformer that converts AC to DC power for the brush motors. If the brush switch, brush breaker, and brush motor all get power, chances are the transformer needs to be replaced.
The next internal system that can go bad is the pump system. The pump system sprays the cleaning péroraison onto the carpet. If no péroraison comes from your automate, the first thing to do is check the jets on the bottom of the unit. The Pony 20 SCA has five jets, these jets are quick assembler jets that rotate away from the jet housing. The jets do not need to be unscrewed from the spray bar. If you need to replace old jet housings, be sure not to over-tighten the jets as this will champion the dynamite on the spray bar. To clean the jets, soak in a Delymer péroraison and then use compressed air to clean the jet nozzles. If the jets are clear and you don’t get any péroraison on your carpet, there are three components that could be failing. These components include pump switches, pumps or solenoids. Use a multimeter to check the tension between the pump switch and the pump solenoid to check which component has failed. If you are not reading any tension from the system, your pump switch has likely failed and needs to be replaced. If you get tension from the pump switch to the pump, one of two components may be bad. The pump and solenoid are connected together but the solenoid can be removed from the pump. The pump in this unit will run continuously when the pump switch is engaged. The solenoid will open and close through the pump and then through the spray bars and jets allowing water to bouturer the carpet. If you are getting power to the solenoid and the pump and you don’t hear the pump running continuously, the pump needs to be replaced. If you are getting power to the pump and the pump is running then the solenoid needs to be replaced.
Overall the Ressortissant Chouette Faveur Pony 20 SCA is easy to maintain and repair. There are other mechanical components that may need replacing, but this articulet covers the mitaine components that make the automate run. It is superbe not to touch en direct wires when diagnosing the automate. For summum prouesse and reliability use only Ressortissant Chouette Faveur parts when servicing this unit. NSS parts can be purchased from studio dealers or online stores. Our certified libéralité technicians can help you find the right parts for your floor equipment.
