Electrical Safety

Position of Saw:

1.  To avoid the possibility of the receptacle getting wet, position the saw on one side of a wall   mounted 
receptacle to prevent water from dripping onto the receptacle or plug.  The user should arrange a “Drip 
Loop” in the cord connecting the saw to a receptacle.  The “Drip Loop” is that part of the cord below the 
level of the receptacle, or the connector if an extension cord is used, to prevent water traveling along the 
cord and coming in contact with the receptacle. 

2.  If the plug or receptacle does get wet, DON’T unplug the cord.  Disconnect the fuse or circuit breaker 
that supplies power to the tool.  Then unplug and examine the plug  for the presence of water in the 
receptacle.

Extension Cords:
1. Use only outdoor rated extension cords.  These extension cords are identified by a marking 
“Acceptable for use with outdoor appliances; store indoor while not used.”  Use only extension cords 
having an electrical rating not less than the rating of the product, see page 12 for extension cord 
specifications .  Do not use damaged extension cords.  Examine extension cord before using and 
replace if damaged.  Do not abuse extension cords and do not jerk on any cord to disconnect.  Keep 
cord away from heat and sharp edges.  Always disconnect the extension cord from the receptacle before 
disconnecting the saw from the extension cord.

2. WARNING: To reduce the risk of electrocution, keep all connections dry and off the ground.  Do not 
touch the plug with wet hands.

3. Ground Fault Interrupter (GFCI) protection should be provided in the circuit(s) or outlet(s) to be used 
for the saw.  Receptacles are available that have built in GFCI protection and may be used for additional  
measures of safety.
