Setup
Unpacking and Assembly:

- Attach Hose: Insert the Twist N Lock Hose (1-1/4" x 4') into the suction port on the front of the vacuum and twist to secure.
Filter Installation:
The vacuum includes two types of filters for different cleaning tasks:
- Foam Filter (for Wet Vacuuming): This filter is designed to protect the motor when vacuuming liquids. Ensure it is properly seated over the motor housing before wet use.
- Cloth Filter with Support Ring (for Dry Vacuuming): This filter is for collecting dry debris. Place it over the motor housing and secure it with the support ring.
Always use the correct filter for the task to ensure optimal performance and prevent damage to the motor.

Operating Instructions
Powering On/Off:
Plug the power cord into a suitable electrical outlet. Press the power button located on the top of the unit to turn the vacuum on or off.
Wet Vacuuming:
- Ensure the foam filter is correctly installed.
- Use the appropriate attachment for liquid spills.
- Move the nozzle slowly over the liquid to allow for maximum suction.
- The vacuum will automatically shut off when the tank is full to prevent overflow. Empty the tank immediately after wet use.
Dry Vacuuming:
- Ensure the cloth filter with support ring is correctly installed.
- Select the appropriate cleaning tool (e.g., crevice tool for tight spaces, utility nozzle for general debris).
- Vacuum dry debris from surfaces.
Blower Function:
To use the blower function, remove the hose from the suction port and insert it into the blower port located on the opposite side of the vacuum. This allows you to clear debris from driveways, workshops, or other areas.

Maintenance
Emptying the Tank:
After each use, especially wet vacuuming, unlatch the motorhead and carefully empty the contents of the tank. Dispose of collected debris and liquids responsibly.
Filter Care:
- Cloth Filter: Regularly blow dust off the cloth filter to maintain optimal suction. Change the filter after multiple cleanings or when suction noticeably decreases.
- Foam Filter: Rinse the foam filter with water and allow it to air dry completely before reinstallation.
Hose Maintenance:
To lock and unlock the hose, turn it 1/4 turn. Ensure the hose is free of blockages and stored properly to prevent kinks or damage.
Troubleshooting
Loss of Suction:
- Check Filter: A clogged filter is a common cause of reduced suction. Clean or replace the filter as needed.
- Check Hose/Attachments: Ensure the hose and all attachments are securely connected and free of blockages.
- Check Tank: The tank may be full, especially during wet vacuuming, triggering the automatic shut-off. Empty the tank.
- Lid Seal: Ensure the motorhead is properly seated and latched onto the tank to create a tight seal.
