UNPACKING AND CLEANING Your new Disc Sander is shipped complete in one container. Carefully unpack the sander and all loose items from the shipping container. Fig. 2, illustrates the sander and all loose items. Remove the protective coating from machined surfaces of the machine. This coating can be removed with a soft cloth moistened with kerosene (do not use acetone, gasoline or lacquer thinner for this purpose). After cleaning, cover all unpainted surfaces with a good quality paste wax.
CONNECTING DISC SANDER TO POWER SOURCE POWER CONNECTIONS A separate electrical circuit should be used for your tools. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-prong grounding type plugs and 3-pole receptacles which accept the tool’s plug.
EXTENSION CORDS Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and a 3-pole receptacle which will accept the tool’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the tool. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Fig. 7, shows the correct gauge to use depending on the cord length.
