WARNING

ELECTRIC SHOCK can kill.

Have an electrician install and service this equipment.

Turn the input power off at the fuse box before working on equipment.

Do not touch electrically hot parts.

Prior to Performing preventative main- tenance, perform the following capaci- tor discharge procedure to avoid elec- tric shock.

---------------------------------------------------------------------

INPUT FILTER CAPACITOR

DISCHARGE PROCEDURE

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

2.Remove the 5/16" hex head screws from the side and top of the machine and remove wrap-around machine cover.

3.Be careful not to make contact with the capacitor terminals that are located on the top and bottom of the Power Board on the right side of the machine.

4.Obtain a high resistance and high wattage resistor (25-1000 ohms and 25 watts minimum). This resis- tor is not supplied with machine. NEVER USE A SHORTING STRAP FOR THIS PROCEDURE.

5.Locate the two capacitor terminals (large hex head cap screws) on the top and bottom of the Power P.C. Board shown in Figure D.1.

6.Use electrically insulated gloves and insulated pli- ers. Hold body of the resistor and connect resistor leads across the two capacitor terminals. Hold resistor in place for 10 seconds. DO NOT TOUCH CAPACITOR TERMINALS WITH YOUR BARE HANDS.

7.Repeat discharge procedure for the other capaci- tor .

8.Check voltage across terminals of all capacitors with a DC voltmeter. Polarity of capacitor terminals is marked on PC board above terminals. Voltage should be zero. If any voltage remains, repeat this capacitor discharge procedure.
