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.

FOREWORD
Delta Model 37-350 and 37-365X DJ-20 is a 8" Precision Jointer with a cutting capacity of 8" (203mm) width, 5/8" depth
(16mm max.) and 5/8" (16mm) rabbeting. Unit includes; heavy-duty 1-1/2 hp, 120/240 volt motor, fence, three-knife
cutterhead, cutterhead guard, and push blocks.
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

1. Disconnect the machine from the power source.
2. Move the transformer primary pigtail to the proper terminal corresponding to the new input voltage.
3. Change the leads in the motor junction box for the proper line voltage, as shown on the motor nameplate.
4. Change the heater elements in the overload block for the proper voltage/amperage, as shown on the motor
nameplate. The correct heater elements can be identified by referring to the chart inside the motor starter box.
OPERATING INSTRUCTIONS
UNPACKING AND CLEANING
CUTTERHEAD ROTATION
The rotation of the cutterhead must be in a clockwise direction when viewed from the left side of the
machine; that is, the knives must be rotating toward the infeed table from the top. If the cutterhead rotation is incorrect,
disconnect the machine from the power source and proceed as follows:
Single Phase Machines – Interchange leads T5 and T8 in the motor junction box.
Three Phase Machines – Interchange any two of the three incoming power lines.
