• Check the operating hours
using the CH Meter.
Criteria
• To have no apparent deformation and flaw.
Service Limit of Chain Pin
(Do not fall short of the limit value.)

• The difference between dimensions a (vertical)
and b (lateral) must be within 0.5 mm.
• To have no apparent deformation and abrasion
• To have no deformation, abrasion and damage
• To be attached securely without loosening
Criteria
• To have no leakage of gear oil from packings,
oil seals or oil plugs.
• Oil is filled enough close to the oil check hole.
• 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.
• Gear oil has viscosity but not stained.
• Refer to "Guidelines and Precautions on Gear
Oil Change Cycle" for the replacement of oil.
