EXTENSION CORDS

31-390 ONLY:

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 matching 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. C, shows the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

FUNCTIONAL DESCRIPTION

FOREWORD

Delta Model 31-390 is a large capacity Edge Sander for fast, efficient, straight and bevel edge sanding with the added ability to handle contour sanding jobs. The standard unit includes; motor, stand legs, push-button controls, magnetic starter, transformer, overload protection, laminate coated tables, graphite platens, three sanding drums with 80 grit medium abrasive sleeves and 6" x 132" belt, sealed ball bearing idler pulley, rubber contact motor pulley, belt guard with hinged end caps and instruction manual.

UNPACKING AND CLEANING

Carefully unpack the tool, two legs and all loose items from the shipping container(s). Remove the protective coating from all unpainted surfaces. This coating may be removed with a soft cloth moistened with kerosene (do not use acetone, gasoline or lacquer thinner for this purpose). After cleaning, cover the unpainted surfaces with a good quality household floor paste wax.

Fig. 2, illustrates the basic sander (A) removed from the shipping container. Place the sander (A) on a supporting surface that will hold 375 lbs., such as two saw horses, which will allow safe and efficient assembly of the legs.
