Oil Replacement
Gear lubrication is an important component in insuring the long service life of your chain hoist.
The type of lubricant will have a great influence. Chain hoist are pre-lubricated at the factory
and do not require initial lubrication. Re-lubrication interval depends upon service. Consult your
local lubricant distributor on the selection that best fits your climate and application.
● Load Chain:
For longer life, the load chain should be lubricated with ISO VG 220 or equivalent extreme-
pressure (EP) lubricating oil.
The chain should be lubricated every week for normal usage. Clean and lubricate more
frequently for heavier usage or severe conditions.
● Hook and Suspension Components:
Hooks and suspension components should be cleaned and lubricated ISO VG 220 or
equivalent extreme-pressure (EP) lubricating oil at least twice per year for normal usage.
Clean and lubricate more frequently for heavier usage or severe conditions.
● Gear box:
Using incorrect type/grade of gearbox oil or the wrong quantity of oil may prevent the winch
from working properly and may affect the ability of the hoist to hold the load.
Gear box should be cleaned and lubricated with ISO VG460 synthetic gear lube for 100
working hours for an initial lubrication and at least once per three months for normal usage.
It requires 250 CC oil in quantity for every time changing.
The oil should be changed more frequently depending on the hoist’s usage and operating
environment.
Dispose of the used oil in accordance with local regulations.
