• Do not use with damaged cord or plug. If appliance is not working as it
should, has been dropped, damaged, left outdoors, or dropped into water, return
it to a service center.
• Do not pull or carry by cord, use cord as a handle, close a door on cord, or pull

Inspection
Carefully unpack and inspect your machine f or shipping damage. Each unit is tested and thoroughly
inspected before shipment, and any damage is the responsibility of the deliv ery carrier who should
be notified immediately.
Electrical
This machine is designed to operate on a standard 15 amp. 115 volt, 60 hz, AC circuit. Voltages
below 105 volts AC or above 125 volts AC could cause serious damage to the motor.
WARNING
To reduce the risk of electric shock - Do not expose to rain. Store indoors.
Grounding Instructions
This appliance must be grounded. If it should malfunction or breakdown, grounding provides a
path of least resistance for electric current to reduce the risk of electric shock. This appliance is
equipped with a cord having an equipment-grounding conductor and grounding plug. The plug
must be plugged into an appropriate outlet that is properly installed and grounded in accordance
with all local codes and ordinances.
D ANGER - Improper connection of the equipment-grounding conductor can result in a risk
of electric shock. Check with a qualified electrician or service person if you are in doubt as to
whether the outlet is properly grounded. Do not modify the plug provided with the appliance — if
it will not fit the outlet, have a proper outlet installed by a qualified electrician.
This appliance is for use on a nominal 120-v olt circuit and has a grounding plug that looks like the
plug illustrated in sketch A below. Make sure that the appliance is connected to an outlet having
the same configuration as the plug. No adapter should be used with this appliance.

User Maintenance Instructions
All service and repair should be performed by qualified vacuum service representative or
electrician. No user serviceable components are employed in the electrical vacuum lid
head assembly. No lubrication of the motor is required.
Cloth Bag & Hose Assembly
Cloth bag and hose assembly are user maintenance items and can be replaced when worn
out. For optimum performance, empty and clean filter bag regularly. A clogged and dirty
bag restricts the flow of air and results in reduced vacuum. The hose assembly can be
maintained by wiping off with a dampened cloth of mild liquid soap and water , then allowed
to dry.
Cord Storage
While not in use storage can be accomplished by winding cord around motor lid assembly .
Cord should be completely unwound from lid assembly during operation.
• Do not use with damaged cord or plug. If appliance is not working as it should, has been
dropped, damaged, left outdoors, or dropped into water, return to service center.
• Do not pull or carry by cord, use cord as handle, close a door on cord, or pull cord around
sharp edges or corners. Do not run appliance over cord. Keep cord away from heated
surfaces.
• Do not unplug by pulling cord. To unplug, grasp the plug, not the cord.
• Do not handle plug or appliance with wet hands.
• Always unplug the machine when removing the motor head off the tank.
This equipment should be stored indoors and not exposed to rain.
Always unplug the machine when removing the motor head off the tank. This equipment
