MAINTENANCE TIPS FOR THE 3 Inspect the fan and fan inlet. This should be done daily. Look for  debris buildup that can cause vibration and result in bearing and drive line damage. The fan should be replaced at the first sign of machine vibration. When it is time to replace the fan, the drive line should also be replaced with new bearings to keep it fresh and up-to-date. 4 Inspect and replace air seals. All rubber seals that are associated  with the fan inlet, intake tubes and doors of the hopper should be replaced as they become worn to allow a tight seal for optimum vacuum. All rubber seals should be replaced routinely. 5 Inspect and adjust the sweeping head. On all air sweepers the  sweeping head is considered the most important part of the machine. Any time the sweeping head is out of adjustment the sweeper performance will decline dramatically. A bent or twisted sweeping head will be very difficult to adjust, and since it is the most important part it should be kept in alignment and the rubber skirts replaced when it is no longer possible to be adjusted. 6 Successful sweeping companies tend to employ a good maintenance program for their sweepers although each maintenance program looks different from company to company. Some companies want their drivers to know how to perform basic maintenance on the sweeper so that they can fix something small out in the field, while others have a full team of mechanics that check each sweeper when they come in the morning. Inspect the rubber skirts daily. The rubber skirts reach the  ground, so make sure they are sealing to the ground creating optimum vacuum. The rubber skirts should be replaced when it is no longer possible to achieve a good seal on the ground. M any companies look to the off-season to buy new (or new to them) equipment. Remember that maintenance starts as soon as you get a sweeper. “It is important to go through that manual when you first receive the unit, even if you’ve been in business for many years, as minor points of maintenance change from model year to model year,” says Costas Cordonis, Schwarze’s warranty and training administrator. “A good preventative maintenance program is the best costbenefit value to your sweeper. Every sweeping contractor and municipality should have a program in place to catch any loose parts, misalignments, vibrations, etc. early on. To keep your sweeper energized and performing well, vital sweeper system and parts must be well maintained and replaced in a timely manner as the need arises.” CORDONIS OFFERS THE FOLLOWING TIPS: 1 C  lean the debris hopper daily. Daily cleaning helps avoid dirt accumulation, which will generate rust as well as restrict the air flow and the performance. 2 M  aintain the hopper screen. This is essential because the hopper screen is the main area where the air flow will move freely to the fan. So maintain the screen, keep it clean and keep it free of any obstructions. 16 NORTH AMERICAN SW EEPER NOVE M BE R 2013 V i si t U s Fol l o w Us
