• Mount the coupling (H1) and lubricate internally with NLGI 2
Lithium grease. Provide an adequate quantity of fat, in order to have a
medium filling.
• Reassembly the motor without forcing onto the seals (H9).
Adjusting the self-lubricating pump
• The automatic lubricating pump is adjusted by the manufacturer
before the shipping.
• If consumption noticeably differs from the indicated value, adjust it
as follows:
-
Remove the upper protection cover;
-
Using a screwdriver and a 10 mm wrench, adjust the adjusting
screw (K). Close the nut and remount the upper protection cover;
-
It is advisable to turn the screw of ¼ of turn and verify the actual
consumption.
Pic. 6.12
Do not reduce oil consumption below the value
indicated in par. 2.3 (for functioning at speeds
different from the maximum, flow is proportionate
to rotating speed).
• ½ turn of the adjusting screw causes a variation in the flow of
approximately 40 - 80 g/h , depending on using conditions.
