Oil control
The oil is controlled by removing the upper oil plug, pos. A. The oil has to be clean and the level has to reach the plug
hole. Oil type: see spare parts list. If the oil is dirty it has to be exchanged.
A. Upper oil plug
B. Lower oil plug
C. Stop screw / grease nipple
D. Inspection screw
The oil is drained by removing the plug, pos. B. In case of contaminated oil, check the seals and wear bushings.
Oil is filled by oil plug, pos. A.
Grease the front sealing system (see spare part list if necessary). Grease lubrication must be done by removing the
stop screw, pos. C, which sits just behind the propeller hub; enclosed grease nipple is fitted, after which grease
lubrication must take place through this. Before any reassembly of the propeller, fill the hub with grease.
The motor casing must be checked in the following way: Remove the inspection plug, pos. D beneath the motor. Any
leakage of oil or liquid can be seen immediately.
In case of abnormal leakage, it is necessary to check the seal in the oil chamber. In case of doubt, Landia can be
contacted. If it is necessary to dry up the motor windings, contact a special workshop.
Equipment
The equipment should be checked for wear and corrosion. The winch needs to be lubricated with grease. The brake
and lock must be checked. Tightening of screws must be done. If the screws are loose, remove them and lubricate
with an adhesive substance (e.g. Loctite) prior to reinstallation.
Disassembling/assembling
A major repair should take place at a special workshop.
Below please find some general conditions regarding disassembling/ assembling of Landia mixer type POPR-I.
