Operating Instructions
Dry Vacuuming
For dry debris collection, ensure the cartridge filter is properly installed. A dust collection bag can also be used for easier disposal of dry debris.

Wet Vacuuming
Before wet vacuuming, remove the cartridge filter and install the foam wet filter. Do not use a dust collection bag for wet pickup. The 4-gallon tank capacity allows for significant liquid collection.

Blower Function
The vacuum can be converted into a powerful blower. To activate the blower function, detach the hose from the intake port and connect it to the exhaust port located on the motor head. This feature is useful for clearing debris from workshops, garages, or outdoor areas.
Extended Reach
The combination of the 7-foot hose and the power cord provides a total cleaning reach of 25 feet, allowing access to larger areas without frequently changing power outlets.

Maintenance
Filter Maintenance
- Cartridge Filter (Dry Use): Regularly check the cartridge filter for dust buildup. Tap it gently to dislodge debris or rinse it with water if heavily soiled. Allow it to air dry completely before reinstallation. Replace if damaged or if suction performance decreases significantly.
- Foam Wet Filter (Wet Use): After wet vacuuming, remove and rinse the foam filter with water. Squeeze out excess water and allow it to air dry completely before storing or using for subsequent wet pickup.
Tank Emptying
To empty the collection tank, unlatch the motor head and lift it off. Dispose of dry debris or liquid contents appropriately. Clean the inside of the tank with a damp cloth if necessary.

Wipe the exterior of the vacuum with a damp cloth. Inspect the hose and accessories for blockages or damage. Store the vacuum and its accessories in a dry place.
