To remove the fuse, turn the fuse cap located on
the line voltage selector in the direction indicated ,
by the arrow. Then remove the fuse plug from the
unit. Put the fuse plug back so that the proper line
voltage marking can be seen through the cut in the
edge of the plug. Whenever the position of the
selector is changed, check the rating of the fuse.
A 3A fuse is to be used for either 220V or 240V
operation and a 6A rating for 110V, 120V or 130V
operation. If the rating of the fuse is correct,
replace cap.

FUSE REPLACEMENT

When the fuse blows, remove the fuse cap and
replace the fuse with a new one. Fig. C.
