The most official version of the sweeper operation sequence and troubleshooting method
Sweepers have been widely adopted across various industries and using them correctly along with timely maintenance can significantly extend their lifespan. Today, I'm excited to share with you the official procedures for operating sweepers and troubleshooting common issues. Packed with essential information, make sure to bookmark this guide!
1. Connect the main unit to the enclosed sweeper body using its quick-connect device. Ensure that the locking pin of the quick-connect device is fully inserted into the pin hole of the sweeper attachment, and that the lever is fully pressed down and locked. When connecting the enclosed sweeper body, make sure that the contact surfaces are free of mud and other impurities to ensure that the connection plates are fully aligned. During the connection process, it is crucial to lift the enclosed sweeper completely off the ground; otherwise, the bottom of the connection plate may not align properly, preventing the locking pin from securing and potentially causing the sweeper to detach, resulting in a serious accident.
2. Connect the hydraulic quick couplings of the enclosed sweeper to the main unit, ensuring that the quick couplings are correctly and securely connected.
When installing or removing hydraulic quick couplings, always make sure to turn off the engine and use the pressure relief feature to release the internal pressure in the pipelines.
Tip: To enhance the lifespan of the motor, try to route the motor's drain lines directly back to the main unit's oil tank whenever possible. This practice helps maintain optimal hydraulic system efficiency and prevents potential pressure buildup that could damage the motor.
3. Maintaining the proper brush compression can enhance the sweeping results. Here's how you can adjust it: ① Position the sweeper on a flat surface that is relatively dirty. ② Slowly rotate the brush roller, lower the sweeper to the ground, and run it in working condition for about half a minute. ③ Lift the sweeper, reverse, apply the brakes, turn off the power source, and check the sweeping traces. The width of the sweeping traces should be around 150mm, and the length should correspond to the length of the brush roller. ④ If the width of the sweeping traces is not close to the reference value, adjust the brush compression by turning the adjustment bolts located at either end of the sweeper.
Tip: Ensure to adjust the bolts on both ends simultaneously to prevent uneven wear of the brushes. This not only helps maintain the sweeper's efficiency but also extends the lifespan of the brushes.
4. Start the equipment and get the brush rolling, then slowly lower the sweeper. Ensure the edge of the sweeper bucket just touches the ground surface, with the back end of the bucket slightly lifted off the ground. As you move the main unit, continue sweeping (as shown in Figure 4.1). For optimal sweeping results, try to keep the travel speed as low as possible. When starting the equipment, keep the engine throttle at idle. Use the variable flow control switch to slowly engage the button, minimizing hydraulic shock and thus protecting the motor during start-up. Run the machine for a few minutes to allow the motor speed to stabilize before increasing to the appropriate throttle setting.
5. During the sweeping process, try to minimize the downward pressure on the sweeper to reduce excessive wear on the brushes. After using the sweeper for a period, check the wear of the brushes and adjust the brush compression appropriately using the adjustment bolts to ensure optimal sweeping results.
6. Operating the brush roller at low speeds and maintaining a moderate travel speed can better remove grit from hard surfaces. If the travel speed is too fast, it will kick up dust and impair the operator's visibility.
7. If there is not much debris on the ground, consider reducing the brush roller speed and the brush compression based on the conditions to minimize wear on the brush segments.
8. Different road surfaces will cause varying degrees of wear on the equipment. For instance, surfaces with residual moisture from milling, dry asphalt, and dry concrete will all exhibit different levels of wear, especially concrete surfaces which tend to have the most significant wear. Theoretically, a set of brush segments has an estimated lifespan of about 200-300 hours.
9. After completing the sweeping, stop the brush roller and lift the sweeper a certain distance from the ground for transportation to the unloading site. You may slightly retract the bucket to prevent material from falling out during transit. During transportation, do not lift the sweeper too high off the ground to avoid accidents.
10. Once at the unloading site, lift and tip the sweeper bucket to dump the material. During unloading, avoid banging or shaking the bucket harshly. If your main unit is not equipped with an automatic bucket leveling feature for lifting, lifting the sweeper to dump materials may cause the sweeper's cover to flip back, potentially striking the hydraulic quick-change connectors or the cab. If your equipment does not have an automatic bucket leveling feature, make sure to keep the sweeper level throughout the lifting process.
Tip: The HCN enclosed sweeper has a patented design feature in the form of a cover anti-overturn mechanism. This innovative solution provides comprehensive protection and enhances operational safety by preventing the cover from flipping too far during use.
11. At the end of the sweeping operation, gradually reduce the throttle, allowing the engine speed to decrease to idle before turning off the fuel supply switch to the sweeper. This process helps ensure that the engine and hydraulic systems are not abruptly halted, which can help extend their longevity.
12. When storing the sweeper, first disconnect the hydraulic quick couplings, then detach it from the quick-change device. Before removing the sweeper, ensure it is placed on a stable and flat surface to secure it properly.
Before disassembling the hydraulic quick couplings, make sure to turn off the engine and use the pressure relief function to release any internal pressure in the lines. This safety measure prevents accidents and damage to the hydraulic system.
