CHARGE PROCEDURE

1.Turn off input power and disconnect input power lines.

2.Remove the hex head screws from the top and the sides of the machine. Remove the handle bar and the wrap-around machine cover.

3.Remove the two case sides. There are hex head screws on each side.

CAUTION

TO PREVENT DAMAGE TO MACHINE, AVOID

UNNECESSARY MOVEMENT OF FRONT PANEL.

4.Obtain a high resistance and high wattage resistor (25-1000 ohms and 25 watts minimum). This resistor is not supplied with the machine. Secure this resistor to a piece of insulating material such as a glastic board. See Figure D.3. NEVER USE A SHORTING STRAP FOR THIS PROCEDURE.
