or local power company. For appliances intended to operate 
from battery power, or other sources, refer to the operating 
instructions.

8. Polarization

If  the appliance is equipped with a polarized alternating-

current line plug (a plug having one blade wider than the 

other), this plug will fit into the power outlet only one way. 

This is a safety feature. If  you are unable to insert the plug 
fully into the outlet, try reversing the plug. If  the plug should 

still fail to fit, contact your electrician to replace your obsolete 

outlet. Do not defeat the safety purpose of  the polarized plug.

9. Grounding

If  the appliance is equipped with a 3-wire grounding-type 
plug, a plug having a third (grounding) pin, this plug will only 
fit into a grounding-type power outlet. This is safety feature. 

If  you are unable to insert the plug into the outlet, contact 
your electrician to replace your obsolete outlet. Do not defeat 
the safety purpose of  the grounding-type plug.

10. Power Cord Protection

Power supply cords should be routed so that they are not 
likely to be walked on or pinched by items placed upon or 
against them, paying particular attention to cords at plugs, 

convenience receptacles, and the point where they exit from 

the appliance.

11. Damage Requiring Service

Unplug this appliance from the wall outlet and refer servicing 

to qualified service personnel under the following conditions:

a.  When the power-supply cord or plug is damaged.
b. 

If  liquid has been spilled, or objects have fallen into the  

appliance.

c. 

If  the appliance has been exposed to rain or water.

d.  If  the appliance does not operate normally by following 

the operating Instructions. Adjust only those controls 

that are covered by the operating instructions as an 

improper adjustment of  other controls may result in 
damage and will often require extensive work by a 
qualified technician to restore the appliance to its normal 

operation.

e.  If  the appliance has been dropped or the cabinet has 

been damaged.

f. 

When the appliance exhibits a distinct change in 

performance-this indicates a need for service.

12. Servicing
