Take care of...
• Check the internal components of the gear
unit for corrosion.
Possible damage if neglected
• Damage to gears and bearings
• Fill gear unit up to correct level.
• Use required oil and correct viscosity.
• Oil level too low -> damage to gears and
bearings
• Oil level too high -> leakage, increased oil
tem
erature
• Viscosity too high (thick oil) -
> lubrication is
unsatisfactory with very low starting
temperature.
• Viscosity too low (very fluid oil) -> too thin
oil film: bearing damage and pitting or
scuffing on gears
• Use clean oil and fill oil trough prefiltered
unit (avoid abrasive particles and water).
• Correct tightening of fixation bolts
• Retorque after 50 to 100 hours of first
o
eration.
• Abrasive wear of bearings and gears due to
foreign particles in oil
• Loosening of bolts and displacement of
the gear unit -> misalignment -> ...
• Correct functioning of control equipment
• Install and connect correctly lubrication group
and control switches.
• No alarm in case of malfunctioning
Damage to bearings and gears
• No lubrication -> damage to gears and
bearings.
• Check the direction of rotation of the low
speed shaft (built in backstop): refer to the
dimensional drawing.
• Wrong direction of rotation -> damage to
the backstop and other parts
Take care of...
• First oil change after 100 hours, max 800
hours to take out small wear particles due to
running in.
Possible dama
e if ne
lected
• Premature damage to gears and bearings
(Final impact - long term effect)
• Regular oil change when oil has lost its
lubrication capacity.
• Avoid enterin
of sand, water, cement,...
• If oil has lost its capacities, anti-scuffing and
anti corrosion are unsatisfactory ->
damage to gears and bearings
• Dama
e to
ears and bearin
s
• Check breather. • Obstructed breather -> leakages
-> too low oil level
-> damage to bearings and gears.
Note: This quick reference for handling the gear unit is not exhaustive.
The obligation to read the complete service manual remains.
