MAINTENANCE AND REPAIR INSTRUCTIONS

WARNING: To avoid serious personal injury, be sure the unit is off and unplugged before cleaning or performing any maintenance on it.

SERVICING OF DOUBLE-INSULATED UNITS

This unit is double-insulated. In a double- insulated unit, two systems of insulation are provided instead of grounding. No grounding means is provided on a double-insulated unit, nor should a means for grounding be added to this unit.

Servicing a double-insulated unit requires extreme care and knowledge of the system, and should be done only by qualified service personnel. Replacement parts for a double- insulated unit must be identical to the parts they replace. Refer any repair to an authorized service dealer. A double-insulated unit is marked with the words “DOUBLE INSULATION” or

“DOUBLE INSULATED.”

CLEARING A BLOCKED IMPELLER

1.Push the switch to the OFF position and disconnect the Blower/Vacuum from the power source and wait for the impeller to stop.

2.Remove the vacuum tubes by reversing the instructions on page 8 (Figs. 7, 8 and 9). The vacuum bag can also be removed by referring to pages 8 and 9 of the Operator's Manual.

3.Carefully remove material blocking the impeller. Inspect the blades to assure no damage has occurred. Rotate the blades by hand to assure the blockage is completely cleared.

4.Replace the vacuum bag and vacuum tubes.

5.Reconnect to power source and resume use.

CLEANING THE UNIT

1.Push the switch to the OFF position and disconnect the Blower/Vacuum from the power source.

2.Use a small brush or the air discharge of a vacuum cleaner brush to keep the air vents free of obstructions.

3.Do not use any strong detergents on the plastic housing or plastic components. Those parts can be damaged by certain household cleaners that contain aromatic oils such as pine and lemon, and by solvents such as kerosene. Moisture can also cause a shock hazard. Wipe off any moisture with a soft cloth.

CLEANING THE VACUUM BAG

1.Empty the bag after each use to avoid deterioration and obstructing air flow, which will reduce the performance of the vacuum.

2.Wearing eye protection and a dust mask, clean the bag as needed. Turn the bag inside out after initial emptying and vigorously shake out dust and debris.

3.Wash the bag once a year or more often if needed as follows:

a.Remove the vacuum bag elbow tube. (Reverse the procedure shown in Fig. 10.)

b.Turn bag inside out.

c.Hang up.

d.Hose down thoroughly.

e.Hang to dry.

f.Reinstall vacuum bag elbow tube (Fig. 10).

INSPECTION OF EXTENSION CORDS

Inspect all extension cords periodically. Look closely for deterioration, cuts or cracks in the insulation. Also inspect the connectors for damage. Replace the cords if any defects or damage appear.

STORAGE INSTRUCTIONS

Store the unit indoors, away from moisture and harmful substances such as fertilizers and solvents. Store in a dry and high or locked-up place, out of the reach of children.
