Pneumatic motor
The pneumatic motor is to be examined and cleaned thoroughly,
using clean, oiled compressed air, free from water, after 200 hours
of operation, however at least once a year. We therefore recom-
mend our central repairs department for maintenance and repair
work on the pneumatic motor.
Avoid damage!
Failure to carry out the stipulated checks can result in considerable da-
mage and a reduction in the performance of the pneumatic motor.
Disassembling the pneumatic motor:
■
Position the pipe milling machine such that the pneumatic motor
is at the highest point of the tool spindle holder.
■
Remove the 6 fillister head screws (18) (see Fig. A).
■
Remove the pneumatic motor.
Assemble in the reverse sequence. Care must be taken to connect
the motor pinion and planetary gear exactly.
Feed unit (see Fig. A)
■
Keep the surface area of the pipe nut (17) free from any dirt and
rust formation and always grease slightly.
■
When changing the gear oil, clean the movement thread and gre-
ase.
Disassembly:
■
Remove the fillister head screw (8).
■
Pull the bolt (5) out of the cover.
■
Then, using the handwheel unscrew the feed unit from the pipe nut.
■
Clean and grease the threaded parts (see the section on “Lubri-
cants and lubrication plan” on page 23).
■
Change any faulty oil rings.
Assembly:
Assemble in the reverse sequence. Do not damage the oil rings
during assembly!
Clamping unit
Avoid dirtying the thread on the eye bolts
(3, Fig. G) in the sprung chain tensioner.
If necessary, clean and grease the thread.
Lubricants and lubrication plan
Lubricants for the pneumatic motor
The pneumatic motor is lubricated via the oiler of the maintenance
unit. Merely add a few droplets of oil into the air intake of the pneu-
matic motor after prolonged downtime.
Lubricating oil for the tool spindle holder
Gear-oil viscosity recommendation for different ambient tempera-
ture ranges:
Machines with country code N34 (recognisable by the Order No.
on the type plate by digit 9 and 10, which have the numbers 3 and
4 7 360 XX XX 34 X) are delivered with BMB 100.
On delivery, the tool spindle holder is filled with ARAL OIL Degol
BMB 460. We urgently request you NOT to use any other gear oil.
Lubricants for gliding surfaces
For lubricating and maintaining the gliding surfaces we recommend
acidless, water-resistant branded, friction-bearing grease products.
