5.6. Lubrication‐Winch
Thewinch has a numberoflubrication and fluidlevel points that
needtobemonitoredandmaintained(seeFigure9).Toensurea
long service life, all points requiring lubrication must be serviced
with the correct time interval as indicated in the Interval Chart
following.

These recommended lubrication intervals are based on
intermittent operation of the winch defined as eight hours per
day,fivedaysperweek.Anumberofotherfactorsalsoinfluence
the lubrication intervals, such as:duration of use, load range,
protection of the unit from the environment, corrosive
environments, ambient temperatures,
etc. These factors may
requireashorterintervalbetweenlubricationchecks.

During normal operation moisture can collect in the motor
housing.This will be even more
prevalent in cold temperature
environments where there is a large deviation between the
operating temperature of the motor and the ambient air
temperature.This accumulated moisture should be drained
regularly (Point C) after the winch has been allowed to sit for a
period of time to allow the water to
separate out from the oil.
