6. Aging sealing strips cause air leakage.

Additionally, low battery levels can reduce the fan's rotational speed, thereby affecting overall vacuuming performance. It is recommended to regularly clean or replace the filter, inspect the suction channels and fan condition, empty the debris hopper promptly, and adjust or replace worn brushes to ensure the sweeper maintains consistent cleaning and vacuuming performance.

Why has the sweeper's driving speed slowed down?

A reduction in the driving speed of a commercial sweeper is typically linked to the battery, drive motor, control system, or mechanical components. Common causes include:

1. Insufficient charge or aging of the lead-acid battery, resulting in lower output voltage and reduced power to the drive motor.

2. Wear, overheating protection activation, or malfunction of the drive motor, which affects driving speed.

3. Abnormalities or damage to the controller parameters, causing the driving speed to be restricted.

4. Damage to tires, the transmission system, or bearings, leading to increased resistance and slower movement.

Additionally, factors such as excessive load, an overfilled waste hopper, or prolonged continuous operation causing high system temperatures may trigger protection modes. It is recommended to first check the battery level and connections, then inspect the drive motor, controller, and transmission components for proper function. Promptly cleaning the equipment and avoiding overload operation will help ensure the sweeper maintains its normal driving speed and operational efficiency.

Why can't the debris bin be installed properly?

Issues with installing the debris bin on a commercial sweeper are usually related to the bin's structure, the position of its guide rails, sealing components, or the operator's technique. Common causes include:

1. Incorrect installation position

2. Guide rails or latches obstructed by foreign objects

3. Bin deformation preventing proper alignment

4. Damaged sealing strips or bin mounting hardware

5. Bin overfilled with debris

Additionally, some sweepers require installation at a specific orientation and angle; improper handling can prevent the bin from locking into place correctly. It is recommended to empty the bin before use, inspect the guide rails, latches, and seals for damage, ensure the bin is not deformed, and follow the equipment manual for proper installation. This ensures the bin is securely fastened and prevents issues such as loosening or dust leakage during operation.

Why does vibration occur during machine operation?

Vibration often occurs during the operation of commercial sweepers and is typically associated with the brush discs, roller brushes, wheel assemblies, motors, and mechanical connection components. Common causes include:

1. Imbalanced installation of the main brush or side brushes

2. Uneven brush bristle wear or entanglement with foreign objects, causing wobbling during rotation

3. Wear on drive wheels, bearings, or transmission components, leading to unstable operation

4. Loose motor mounting screws or abnormal motor operation, which can also cause equipment vibration

Additionally, uneven ground surfaces, abnormal tire pressure, or large foreign objects jammed inside the machine can lead to noticeable vibration during operation. It is recommended to inspect and clean the brushes, ensure they are securely installed, check for loose motor components, bearings, and fasteners, and promptly replace worn parts to ensure smoother and safer sweeper operation.

Why is a fault code displayed on the control panel?

If the control panel of a commercial sweeper suddenly displays a fault code, it usually indicates that the machine has detected an anomaly in the electrical system, drive system, or sensors. Common causes include:

1. Abnormal battery voltage

2. Motor overload

3. Controller malfunction

4. Loose wiring connections

5. Damaged sensors or abnormal loads during operation

Fault codes and protective shutdowns may also be triggered by prolonged heavy-duty operation, brushes becoming jammed by obstacles, or motor overheating. It is recommended to troubleshoot based on the fault code definitions: first, check the battery level and wiring connections; verify that the brush deck, side brushes, and drive wheels are free of obstructions; and ensure all motor and sensor connections are secure. If the fault code persists, contact a professional technician for inspection to prevent further equipment damage caused by continued operation.

What should you do if a sweeper malfunctions and the issue cannot be resolved?
