13.Operating Functions and Protection Features

13.1. Low Voltage Protection

This machine is equipped with a two-level low voltage protection system designed to protect the battery from damage and ensure safe operation.

Level 2 Protection (Battery voltage below 41V):

• Driving (travel) function remains available
• All sweeping and scrubbing functions are automatically disabled
• Return the machine to the charging area immediately
• Recharge the battery as soon as possible

Level 1 Protection (Battery voltage below 40V):

• All machine functions are automatically shut down
• This protection prevents excessive battery discharge and permanent damage
• Recharge the battery immediately before resuming operation

Frequent operation below the protection voltage may significantly reduce battery service life.

13.2. Hill Start Assist Function

The machine is equipped with a hill start assist function to improve safety and ease of operation on inclines.

• When the machine stops on an uphill slope, the brake does not need to be applied
• The system allows the machine to roll backward slowly and in a controlled manner
• Press the accelerator to move forward normally

Important:

• Do not turn off the power while the hill start assist function is active, as this may disable the function and affect safety

13.3. Adjustable Water Flow Function

The machine features water flow adjustment controls.

• Water flow can be increased or decreased using the designated buttons
• Allows adjustment of dust suppression or cleaning water volume
• Suitable for different operating environments and surface conditions
• Helps improve cleaning efficiency while reducing water consumption

13.4. Front Side Brush Anti-Collision Protection

Both front side brushes are designed with forward and backward swinging arms.

• Brushes automatically deflect when contacting obstacles
• Improves cleaning performance along edges and corners
• Protects the brush system and machine body from impact damage
• Extends the service life of the brush components

14. After Use Maintenance

• Check brushes for wear and debris.
• Empty the vacuum collection bin.

General Charging Principles

• Charge after each use. Recharge the battery as soon as the machine finishes operating.
• Do not deep discharge frequently. Avoid running the battery down to its minimum protection voltage.
• Use as you charge, charge as you use. Frequent partial charging is recommended to maximize battery life.

1. What Is a Short Circuit and How Does It Affect Battery Performance?

A short circuit occurs when the positive and negative terminals are directly connected, either externally or internally within the battery, causing a high current flow.

Effects of a Short Circuit:

• During charging, battery voltage rises very slowly and remains at a low level
• Electrolyte temperature increases rapidly and excessively
• Electrolyte density increases slowly or shows little to no change
• During discharge, terminal voltage drops quickly

Short circuits can cause severe damage, overheating, and permanent loss of battery capacity.

2. What Is Over-Discharge and How Does It Affect Battery Performance?

Over-discharge occurs when the battery continues discharging after reaching its minimum operating voltage.

Effects of Over-Discharge:

• Battery voltage drops sharply in a short time
• Internal chemical reactions become unstable
• Repeated over-discharge causes the positive plates to lose activity
• Battery service life is significantly reduced
• Operating time decreases and charging time increases

To protect battery life, avoid repeated deep or over-discharge conditions.

3. How Should the Battery Be Stored After Use?

Batteries are sensitive components. If the machine will not be used for an extended period:

• Remove the battery from the machine
• Store it in a dry, well-ventilated location at room temperature
• Avoid leaving the battery installed, as connected electrical components and circuit boards may cause continuous micro-discharge, even when the machine is powered off

Proper storage helps prevent capacity loss and premature aging.

4. Why Does Battery Life Become Shortened?

Common causes of reduced battery life include:

• Insufficient charging over long periods
• Leaving the battery uncharged for extended periods after discharge
• Frequent over-discharge during operation
• Using a non-standard or non-approved charger, leading to over-charging
• Voltage imbalance between batteries within a battery pack
• Long-term operation under low-voltage conditions

To ensure optimal performance and service life, always use the specified charger and follow the recommended charging and usage practices.

17. Troubleshooting

Problem	Possible Cause	Solution
Poor sweeping performance	Worn brooms	Replace brooms
Excessive dust	Clogged filter	Clean or replace filter
Machine will not move	Low battery	Recharge

18. Storage

• Clean the machine thoroughly before storage.
• Store indoors in a dry, well-ventilated area.
• Fully charge batteries before long-term storage.
• Disconnect battery (if applicable).

Proper use and maintenance will ensure safe operation and long-lasting performance.

19. Safety Notes

• Always test the horn and lights before operation.
• Do not operate on slopes exceeding the manufacturer’s limits.
• Avoid pressing individual function buttons after starting the sweeper unless necessary.
• Make sure no debris is obstructing brushes or water spray before starting.
