2.8 Lubricating gear box, axis 6
• Remove the plug from the drain hole (1). See Figure 8
• Grease through the radial nipple of the turning gear (2).
• Rotate axis 6 while greasing.
• Continue to grease until new grease exudes from the drain hole (1). See Volume
below.
Move axis 6 backwards and forwards a couple of times before the plugs are replaced,
so that excess grease is pressed out. This is to prevent over-pressure in the gearbox,
with risks for leakage.
Volume:
- 0.30 litres (0.085 US gallon).
- About 0.4 litres (0.11 US gallon) should be used when changing the grease.
Type of grease:
- ABB 3HAC 2331-1 Molywhite RE No 00
Figure 8 Greasing axis 6.
