Gearbox / oil change

Fig. 68
Dispose of waste oil in accordance with environmental protection requirements.
Oil lubrication
Under normal operating conditions, the lubricant must be changed at least every 10 years. Under exceptional con‐
ditions, e.g. increased ambient temperatures, we recommend that oil changes be adapted to suit these conditions.
Oil quality
Universal gear oil Shell Donax TD 10W-30 with wear-minimising additives, range of viscosity 10W-30. If oils are
used that are not approved, malfunctions of the slipping clutch may occur. For higher or lower ambient temperatures
than -20 °C to + 40 °C, contact the manufacturer.
Oil change
Drain the old oil at operating temperature. First remove the control unit with the plug-and-socket connections (2)
under the electrical equipment cover set (3). Now remove the screws of the gearbox cover (1). Turn the gearbox in
such a way that the oil is drained. The flushing oil should have a viscosity of 46 – 68 mm
The quantity of flushing oil used should be approximately twice that specified for lubrication. Then flush the gears
by switching the hoist on and allowing the hook to run several times over the entire length of its path. Then drain the
flushing oil and refill the gearbox with new oil. For the required oil quantities please refer to the table below. Part no.
