15.  Stay alert, watch what you are doing and use 
common sense when operating an appliance.  
Do not use an appliance while you are tired or 
under the influence of drugs, alcohol or medication.   
A moment of inattention while operating 
appliances may result in serious personal injury.

on the appliance.  These carry important safety 
information.  If unreadable or missing, contact

k.  The battery Charger gets hot during 
use.  The Charger’s heat can build up 
to unsafe levels and create a fire 
hazard if it does not receive adequate 
ventilation, due to an electrical fault, or if it is 
used in a hot environment.  Do not place the 
Charger on a flammable surface.  Do not 
obstruct any vents on the Charger.
