Insert the four swivel casters into the designated holes on the bottom of the vacuum tank. Push firmly until they click into place, ensuring secure attachment for mobility.
Connect the 1-7/8 inch x 7 feet CLICK-N-LOCK EVA Hose to the intake port on the front of the vacuum for suction mode. For blower functionality, attach the hose to the exhaust port located on the motor head.
For dry vacuuming, ensure the cartridge filter is securely installed over the motor housing inside the tank. For wet vacuuming, the cartridge filter must be removed. A foam filter (not included, but typically used for wet applications) can be installed if desired, but the unit can operate for wet pickup without it.

Utilize the built-in cord management system on the vacuum's motor head to neatly store the power cord when not in use, preventing tangles and ensuring easy access.
Plug the power cord into a grounded electrical outlet. Press the yellow power switch located on the top of the motor head to turn the vacuum on or off.

Ensure the cartridge filter is installed. Attach the hose to the intake port. Select the appropriate accessory (e.g., Pick Up Tool, Crevice Tool) for the surface you are cleaning. Move the nozzle over the dry debris to collect it.
Remove the cartridge filter before wet vacuuming. Attach the hose to the intake port. Use the Floor-Squeegee Tool for efficient liquid pickup. Move the squeegee over the liquid spills to collect them into the tank.
To use the blower function, detach the hose from the intake port and securely attach it to the exhaust port on the motor head. The vacuum will now expel air, allowing you to clear debris from surfaces or inflate items.

The vacuum comes with various HOOK-N-STORE accessories. Attach extension wands for extended reach. Use the Pick Up Tool for general debris, the Crevice Tool for tight spaces, and the Floor-Squeegee Tool for liquids or by removing the squeegee insert, for dry floor cleaning.

Regularly empty the 6-gallon tank to maintain optimal suction performance. For dry debris, unlatch the motor head and carefully lift it off. Dispose of collected debris. For liquids, unlatch the motor head and pour out the liquid from the tank.
For dry use, periodically blow dust off the cartridge filter to maintain suction. Replace the cartridge filter (Koblenz part numbers: 45-1168-00-9 Standard, 45-1170-00-5 Fine dust, 45-1169-00-7 Washable) after multiple cleanings or when performance decreases. For wet use, ensure the foam filter (if used) is clean and free of debris.
Inspect the 1-7/8 inch x 7 feet EVA hose and all accessories for blockages or damage before and after each use. Clear any obstructions to ensure proper airflow. Store accessories using the HOOK-N-STORE system around the tank's perimeter.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Not plugged in; tripped circuit breaker | Ensure cord is securely plugged into a working outlet; check and reset circuit breaker. |
| Low suction | Clogged hose/filter; full tank; incorrect filter for application | Check hose and accessories for blockages; clean or replace filter; empty tank; ensure correct filter is used (remove cartridge for wet). |
| Motor runs, but no suction | Hose not properly attached; blockage in hose/nozzle | Ensure hose is securely connected to the intake port; clear any blockages in the hose or nozzle. |
