Extension Cords; Unpacking And Cleaning; Operating Instructions - Delta 31-340 Instruction Manual

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 machine's plug. When
using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord
will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D, 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.

OPERATING INSTRUCTIONS

FOREWORD
Delta Model 31-340 is the ultimate workshop machine for wood sanding and metal grinding. The 3000 SFM belt speed
is ideal for metal grinding, deburring and sharpening, as well as sanding and buffing jobs. The 8" diameter disc
operates at 1725 rpm for finishing hard and soft woods, plastics, compositions and more.
Carefully unpack the machine 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.
