9.3. Lubricating instructions
Relubricate the main bearing after about 7,000 hours of
operation, using a KP 2 N-30 to DIN 51 502 grease such
as Wälalit LZ 2 or Klüberlub BE 41-542 (approx. 58 g on
DE and approx. 16 g on NDE).
Use a conventional grease gun and press the grease into
the hydraulic-type grease nipples to DIN 71 412 AM 10x1.
The relubricating points are provided on the D and ND
end shields of the machine. The DE grease nipple is
located behind the traction sheave. Turn the traction
sheave until one vent hole coincides with the grease nip-
ple, and the nipple is thus accessible.
