The motor casing must be inspected in the following way:
Remove the inspection plug pos. D beneath the motor. Any seepage of oil or liquid can be seen immediately.
In case of abnormal seepage it is necessary to check the seal in the oil chamber.
If it is necessary to dry up the motor windings, contact an electric motor repair shop.
EQUIPMENT
The equipment should be inspected for wear and corrosion. The winch is to be lubricated with grease. Inspect
brake and lock. Retighten screws. If the screws are loose dismount them and lubricate with Loctite 243 prior to
re-mounting.
MOUNTING/DISMOUNTING OF UNIT
NOTE
: a major repair should take place at a workshop which is specialized in this type of repair. We can refer
to a service partner in your territory.
Below please find some general conditions regarding mounting/dismounting of Landia mixer type POPR-I.
The drawing attached to the spare parts list shows the construction of the unit. Not all parts can/should be
dismantled, e.g. do not press the rotor off the shaft.
When dismounting the unit, handle the mechanical seals with care as they are not shock resistant.
Prior to remounting, all sealing surfaces must be cleaned, all O-rings must be checked and changed if necessary.
Adhesive substance (Loctite 243) must be applied on all bolt joints. All bolts must be tightened with a torque
