Operating Instructions

1. Power On/Off and Suction Control

• The vacuum is operated via the controller, which can be clipped to your waist belt.
• Press the ON/OFF button on the controller to start or stop the vacuum.
• Use the air volume selection button to cycle through three power settings: Maximum, High, and Normal. Select the appropriate power for the cleaning task.
• The vacuum features a mode memory function, which allows it to start in the last used power setting.

2. Using the LED Job Light

• The controller is equipped with an LED job light. Press the dedicated light button on the controller to illuminate darker areas, improving visibility during operation.

3. Effective Cleaning Techniques

• For general floor cleaning, use the nozzle assembly with the telescopic pipe.
• For hard-to-reach corners, crevices, or delicate surfaces, attach the flexible rubber nozzle directly to the bent pipe or telescopic pipe.
• Move the nozzle slowly and steadily over the surface to allow the vacuum to effectively pick up debris.

Maintenance

Regular maintenance ensures optimal performance and extends the life of your vacuum cleaner.

1. Dust Bag Management

• The DVC660Z has a large 6-liter dust capacity (5.5-liter cloth dust bag capacity).
• Check the dust bag regularly. Replace or empty the cloth dust bag when it is full or when suction power decreases significantly.
• To empty the cloth dust bag, remove it from the unit, shake out the contents, and reinstall. Ensure it is properly sealed.

2. HEPA Filter Cleaning

• The HEPA filter captures very fine particles effectively. Periodically inspect the HEPA filter for dirt and debris.
• To clean, gently tap the filter to dislodge dust or use a soft brush. Do not wash the HEPA filter with water unless specified by Makita, as this can damage it.
• Replace the HEPA filter if it is damaged or if cleaning does not restore suction performance.

3. General Cleaning

• Wipe the exterior of the vacuum unit with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Check the hose, pipes, and nozzles for blockages. Clear any obstructions to maintain optimal airflow.
