be taken to avoid inhalation and minimize skin contact.  
16.  
check for damaged parts. Before using any tool, any part that appears damaged  
should be carefully checked to determine that it will operate properly and perform its  
intended function. Check for alignment and binding of moving parts; any broken parts  
or mounting fixtures; and any other condition that may affect proper operation. Any part

Do not operate tool if under the influence of alcohol or drugs. Read warning labels

use proper size and type extension cord. If an extension cord is required, it must be  
of the proper size and type to supply the correct current to the tool without heating up.

to the tool. This tool requires use of an extension cord of 0 to 10 amps capability (up  
to 50 feet), with wire size rated at 18 AwG. Longer extension cords require larger size  
wire. If you are using the tool outdoors, use an extension cord rated for outdoor use  
(signified by “WA” on the jacket).
