STROBEL
5. 1 Oil drain pipe
To facilitate machine maintenance, at the machine body or at the lower
cover respectively there is oil drain pipe 133.0764 going through the table
top, thus enabling to drain the oil without removing the machine head.
The oil drain pipe
133.0764 is sealed by means of seal ring 193.0530 and
screw 173.0772 (fig. 18).
For machine assembly and for shipment the screw borings in cover
112.0085 are sealed by means of ring 193.0530 and screw 193.0772 as
well as three rings 190.0010 and screws 172.0521 each (fig. 17).
Before mounting head to the table top screws 193.0772 and 172.0521
with the seal rings have to be removed and the oil drain pipe with sealing
washer 190.0178 has to be mounted and sealed (fig. 18).
To drain the waste oil put a receptacle under the pipe and remove screw
193.0772 only. After having drained the oil screw on screw 193.0772 and
seal
it.
Dispose of old oil properly!
A T T E N T I 0 N ! Danger!
Observe safety instructions under 1 .3 and operating
instructions before starting any maintenance or repair
works. Failure to do so can result in serious bodily
injuries.
After having drained the oil rinse the machine thoroughly with petroleum
and
then refill with new oil.
When removing the inner cover, also oil pipe 196.0716 for the automatic
lubrication which comes from the oil pump through the inner cover with oil,
is removed (fig. 6)
When re-mounting the inner cover please observe that the lower end of the
main oil pipe is put into the conical opening of the oil outlet piece of the oil
pump (fig. 6). If you fail to do so the automatic lubrication does not work
and the machine may be damaged seriously by jamming of the shafts in the
bearings.
Therefore these
instructions should be observed carefully and after refilling
new oil make sure the automatic lubrication works properly by briefly
operating the machine and controlling the class at the outer cover.
Before operating
the machine make sure that all protection devices (e. g.
cover, belt-guard, etc.) are
effective and that all screws are tightened.
