be taken so as not to overfill the disc brake as this could inhibit
the setting and releasing of the brake and cause additional drag
and wear to the disc brake components.Fill/Add oil to the disc
brake
thru the fill/vent plugonthe top ofthe disc brakehousing
(Point D).Check the level by removing the level plug (Point E).
Draining the oil from the disc brake can be accomplished by

Gearbox – (Points G/H/I)‐Duringthe first hours of operation of
the reduction gears, due to the contact between surfaces that
have not been run‐in, you may find metallic particles in the oil.
Undoubtedlytheseparticleswillhaveanegativeeffectonthelife
of the gears and bearings
within the gearbox.To reduce the
number of metallic particles in the oil we recommend changing

should be petroleum based, non‐detergent gear fluid containing

5.7. Lubrication–Levelwind
In addition to the winch lubrication items covered in Sect. 5.6,
some units are supplied with a levelwind that has several
lubrication and fluid level points that need to be monitored and
maintained(seeFigure10).Toensurealongservicelife,allpoints
requiring lubrication must be serviced with the
correct time
intervalasindicatedintheIntervalChartfollowing.

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
