Porter-Cable 7812 instruction manual Dry Pick-Up, Wet Pick-Up

NOTE: A small sponge filter is located next to the top filter. This filter helps to cool the motor. Check the filter on a regular basis. If it is dirty, clean it by blowing dry compressed air through it.

DRY PICK-UP

CAUTION: Do not pick up anything that is burning, smoldering, or smoking such as matches, cigarettes, or hot ashes.

Do not use to vacuum combustible explosive materials, such as coal, grain, or other finely divided combustible material.

Do not use to vacuum hazardous, toxic, or carcinogenic materials, such as asbestos or pesticide.

The vacuum cleaner may be used to pick up dry material with or without a dust bag installed. The dust bag provides a convenient method for disposing of the material that is collected.

Always use a paper bag when collecting fine dust. The bag will reduce clogging of the flat filter, and increase dust holding capacity.

WET PICK-UP

CAUTION: Never pick-up explosive liquids (e.g. gasoline, diesel fuel, heating oil, paint thinner, etc.), acids or solvents.

Always remove paper bag before picking up liquids or wet material. The vacuum motor will shut off automatically when the container is full. Move the power switch to the “OFF” position before emptying container.

CAUTION: DISCONNECT APPLIANCE FROM POWER CIRCUIT BEFORE REMOVING POWER UNIT FROM CONTAINER.

The Model 7814 has a drain hose located at the rear of the container. Remove the hose from its holder and point it downward to drain the container (see Fig. 10).

Always clean and dry the interior of the container after using the machine for wet pick-up. Also clean the two brass colored electrodes (see Fig. 11), on the bottom of the motor unit. These electrodes are part of the low-voltage system that stops the vacuum motor when the container is full of liquid or wet material.
