It is com pletely safe during norm al operation. H ow ever, carelessness in servicing the oven can result in an electric shock or possible danger from a short circuit. You are asked to observe the follow ing precautions carefully. A lw ays rem ove the pow er plug from the outlet before servicing. 9) R em ove the door open button and button spring from the control panel. 10) R everse the above steps for reassem bly. To rem ove high voltage capacitor 1) R em ove a screw w hich secure the grounding ring term inal of the H . V. diode and the capacitor holder. 3) R everse the above steps for reassem bly. High voltage circuit w iring 7. To rem ove m agnetron 1) R em ove a screw w hich secure the m agnetron. 3) R everse the above steps for reassem bly. DISASSEMBLY AND ASSEMBLY NOTE N ever install the m agnetron w ithout the m etallic gasket plate w hich is packed with each m agnetron to prevent m icrow ave leakage. W henever repair w ork is carried out on m agnetron, check the m icrow ave leakage. It shall not exceed 4m W /cm 2 for a fully assem bled oven w ith door norm ally closed. 8. To rem ove w ind guide assembly 1) R em ove a screw for earthing. 2) R em ove the noise filter from the w ind guide. 3) R em ove a screw w hich secure the w ind guide assem bly. [. . . ] COMPONENT TEST PROCEDURE H igh voltage is present at the high voltage term inal of the high voltage transform er during any cooking cycle. It is neither necessary nor advisable to attem pt m easurem ent of the high voltage. B efore touching any oven com ponents or w iring, alw ays unplug the oven from its pow er source and discharge the capacitor. H igh voltage transform er (1) R em ove connections from the transform er term inals and check continuity. [. . . ]
