12. Maintenance Guidelines

12.1 Daily Maintenance

• Empty and rinse recovery tank
• Clean brushes and squeegee
• Check machine for leaks or damage

12.2 Weekly Maintenance

• Inspect squeegee blades for wear
• Clean solution filter
• Check tire condition

⚠️ Always turn off the machine before maintenance.

12.3 Battery Maintenance

• Recharge batteries after each shift
• Do not allow batteries to fully discharge regularly
• Keep battery terminals clean and dry

This machine is equipped with optional sealed lead-acid batteries featuring maintenance-free operation, no routine servicing, and automatic pressure-relief protection.

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.

12.4 Squeegee Maintenance – Disassembling the Squeegee (Replacing Blades)

12.4.1 Removing the Squeegee Assembly from the Machine

1. Locate the squeegee assembly at the rear of the machine.
2. Find the vacuum hose connected to the top or center of the squeegee.
3. Hold the hose firmly and pull it straight off the squeegee inlet.
   • Do not twist excessively.
4. Locate the two mounting knobs / hand knobs on the left and right sides.
5. Turn both knobs counterclockwise until they are fully loosened.
6. Carefully lower and remove the squeegee assembly from the mounting bracket.
7. Place the squeegee on a clean work surface.

12.4.2 Removing the Squeegee Blades

1. Loosen the hand knobs or fasteners holding the clamps.
2. Slide the rubber squeegee blades out of the blade holder.
3. Locate the blade retaining clamps or brackets.
4. Remove the rear clamp, then the front clamp.
5. Inspect the blades:
   • Replace if worn, torn, or uneven
   • Flip if the blade has a usable second edge

12.4.3 Installing the Squeegee Blades

1. Insert the front blade into the front blade slot.
   • Make sure it is centered and straight.
2. Install the rear blade in the same way.
3. Reinstall the front and rear clamps.
4. Tighten the hand knobs by hand only.
   • Do not over-tighten.

12.4.4 Installing the Squeegee Assembly

1. Lift the squeegee assembly and align it with the mounting bracket.
2. Position the assembly evenly between the mounts.
3. Tighten both mounting knobs clockwise until secure.
4. Reconnect the vacuum hose:
   • Push it fully onto the squeegee inlet
   • Ensure a tight seal

12.4.5 Squeegee Adjustment

Proper adjustment is important for good water pickup.

1. Lower the squeegee to the floor.
2. Check that both blades touch the floor evenly.
3. Adjust the angle or height if needed using the adjustment knobs.
4. The rear blade should form a smooth, even curve against the floor.

12.4.6 Final Check

1. Turn the machine ON.
2. Run the machine for a short test.
3. Check for:
   • Proper water pickup
   • No water streaks
   • Secure hose connection
4. Re-adjust if necessary.

Notes

• Always replace blades in pairs for best performance.
• Clean the squeegee after each use to extend blade life.
• Improper installation can reduce water recovery.

12.5 Cleaning Brush Maintenance

Daily Maintenance (After Each Use)

• Power off the machine and remove the brush
• Remove hair, string, and debris from bristles
• Rinse with clean water only (no hot water or corrosive chemicals)
• Air dry in a well-ventilated area; do not expose to direct sunlight

Routine Inspection (Weekly / Monthly)

• Check bristle wear and deformation
• Ensure brush is securely mounted
• Inspect drive hub for abnormal wear
• Rotate brush position if applicable to ensure even wear

Replacement Criteria

Replace the brush when:

• Bristle length is worn to approx. 50% of original
• Bristles are severely bent, flattened, or broken
• Cleaning performance is noticeably reduced
• Abnormal vibration or noise occurs (after excluding other causes)

Proper Use Guidelines

• Use the correct brush type for the floor surface
• Do not over-apply brush pressure
• Avoid prolonged use on uneven or sharp surfaces
• Do not operate with excessively worn brushes
