Lubrication
The bearings on the cutterhead are factory
lubricated and sealed for life – no lubrication
required.
Gearbox
– The oil in the gearbox must be
drained and replaced after the first 20 hours of
operation. (See the
Lubrication Table
).
Inspect levels periodically and change yearly.
Replace gear oil more frequently under heavy
use. Fill until the oil reaches the top of the filler
plug port for correct oil level.
Figure 39
