Do not use a high pressure water to clean the winch as it may inject
moisture into vital mechanical parts.
WARNING
It is of utmost importance that the cleanliness and lubrication of all moving parts are
observed at all times.
For most Sepson winches, the gear drive is placed inside a closed container filled
with grease. If the gear drive needs to be repaired use grease of NLGI 2 grade that
has lithium complex soap as thickener. Sepson recommends Mobil Grease XHP
222 or similar. Grease the winch nipples every year.
Sepson winches with planetary gear may leak some oil. The seal between the rope
drum and gear housing is a V-ring, to allow the rope drum to rotate. A small amount
of oil will leak out from the V-ring seal.
Note that all grease consists of oil and a thickener. If the winch is not used for a
long time the grease will bleed and seperate the oil and thickener. The “bleeding”
temperature for Mobil Grease XHP 222 is 30 °C - 40 °C.
On some winches, the gear drive runs in an oil bath and this oil should be replaced
every third year.
The position of the drain plug, filler hole and level plug is found in technical
information for the winch.
Check that there is no water condensation in the gear housing. Unscrew the
draining plug in the bottom of the gear housing once a year and drain. Use
protective gloves and collect the liquid in a vessel.
