Oil Leakage • Check visually. • To have no leakage of gear oil from packings,
oil seals or oil plugs.
Replace the Packing
and the Oil Seal.

Oil
•
Check the oil level through the oil cap at the top (shown by an arrow)
for electric chain hoist equipped with the friction clutch with mechanical
brake. (Do not open the oil check hole at the side. Or, oil leaks out.) When
checking the oil level, insert the check bar into the oil check hole, tilting the
bar slightly, to see the oil level.
•
The distance between the hole and the oil level is 75 mm for the body size
B, 100 mm for the body size C/D, 120 mm for the body size E, and 130
mm for the body size F respectively.
