MACHINE MAINTENANCE 

 
All general information about machine maintenance is based on normal machine working 
conditions: indoor, moderate dust and low moisture environment, and maximum rotation of 
32 RPM of turntable/rotary arm. They should be regarded as guidelines, reviewed and 
corrected according to requirements of actual use and conditions. 
 

MOTOR MAINTENANCE 

 
An occasional inspection of the brushes should be made in order to establish a wear rate. 
Replacement brushes should be installed before old brushes wear to 9/16” long, measured 
on the long side. After replacing brushes run the motor near rated speed for at least 1/2 
hour with no load to seat the new brushes. 
Failure to properly seat the new brushes may cause commutator damage and rapid wear of 
the new brushes. If the commutator becomes rough, scored or out of shape, a competent 
motor shop should disassemble it and resurface the commutator. 
With every third brush change, have a competent motor shop resurface the commutator and 
blow the carbon dust out of the motor. 
 

REDUCER OIL CHANGE 

 
All external cap screws and plugs on the reducing transmission should be checked for 
tightness after the first week. It is recommended to change the oil every six months or at 
least 1800 hours of operation, whichever comes first. When adding or changing oil, the 
transmission should never be filled above the oil level mark indicated, because leakage and 
overheating may occur. Below is the list of the type of lubricant that should be used.

RING BEARING MAINTENANCE (when applicable) 

 
The ring bearing (located under the turntable) should be re-lubricated internally and 
externally. 
 

Internally:

 by injecting grease into all the lubrication nipples in succession until a collar of 

fresh grease appears around the perimeter of the ring. The re-lubrication interval suggested 
for these bearings, used in Stretch Wrapping Machinery is 750 hours, with a maximum 
period of 6 months. The lubricant should be fresh and applied in sufficient quantities to 
make sure all surfaces are lubricated.
