3. Right battery cartridge
4. Left battery cartridge
  • CAUTION: Always install the battery cartridge fully until the red indicator cannot be seen. If not, it may accidentally fall out of the appliance, causing injury to you or someone around you.
  • CAUTION: Do not install the battery cartridge forcibly. If the cartridge does not slide in easily, it is not being inserted correctly.
  • The cleaner has double battery slots. You can choose with either double batteries or single batteries according to your needs.

With double batteries

  • Continuous drive with two batteries allows longer runtime and more efficient cleaning. When the first battery is becoming empty, the cleaner automatically switches a power source, so it continues working with the second battery.
  • NOTE: The right battery slot (when facing the front of the cleaner) has priority over the left battery slot.
  • The left battery slot will only be identified as a power source, either when no battery is installed in the right battery slot or the battery in the right battery slot becomes empty.
  • NOTE: You can remove the battery from the right battery slot and recharge it after the cleaner has switched its power source from the right battery slot to the left without ceasing operation. To give priority back to the right battery slot after installing a recharged battery, restart the cleaner.
  • NOTE: When the cleaner switches the power source from the first battery to the second, it may require a temporary halt in operations, causing a slight loss of suction. This is not malfunction so the cleaner recovers and resumes operations immediately after the pause.

With a single battery

  • Only one battery is required as a power source in either the right or left battery slot. The cleaner automatically determines which battery slot is available.

CYCLONE ATTACHMENT

Optional accessory
NOTE: When using the cyclone attachment with this appliance, a bent pipe is also required.

  1. Cyclone attachment

About the cyclone attachment
Using the cleaner with the cyclone attachment installed reduces the amount of dust that enters the dust bag, which helps to prevent the suction force from weakening. In addition, cleaning after use is also simple.

  • CAUTION: Always ensure the tool is switched off and the battery cartridge is removed before carrying out any work on the tool. If the battery cartridge is left inserted, the cleaner may start unexpectedly and result in injury.
  • CAUTION: Clean the mesh filter of the cyclone attachment and the dust bag of the cleaner unit when they become clogged. Continued use in the clogged condition may result in heating or smoke.
  • NOTICE: When the cyclone attachment is attached, do not use the cyclone attachment in the horizontal or upward-facing condition. Doing so may cause the mesh filter to become clogged.
  • NOTICE: Always use the cleaner with the dust bag installed, even when using the cyclone attachment. Using the cleaner without the dust bag installed may result in a motor malfunction.
  • NOTE: Check that the cyclone attachment, cleaner, and straight pipe are locked properly before use.
  • NOTE: Empty the dust case of the cyclone attachment and the dust bag of the cleaner when the dust has accumulated. Continued use will result in weakened suction force.
  • NOTE: You can use the cyclone attachment with or without the lock function.
  • NOTE: To install or remove the cyclone attachment, refer to the section “Using as a cleaner”.
