Troubleshooting (type RDG (**)).

Fault
Motor and cutting tool stop
functioning
Defective chain wheel
Faulty cutting procedure
The function of the machine is
reduced or ineffective
Strong vibrations

Maintenance unit.

for type RDG (**)
The service life of a pneumatic system mainly depends on the pro-
cessing of the compressed air.
Therefore, filters and line oilers are built into each pneumatic sys-
tem as maintenance units; however, these have to be operated and
serviced correctly.
Installing the maintenance unit
The installation is carried out in the direction of the arrow, a near
as possible to the consumer (max. distance away, 10 m).
Filter
The compressed-air filter cleans the compressed air, thereby filte-
ring out the moisture and solid substances. A filter insert is installed
of 40 μm. Smaller pore sizes can be supplied upon request.
Maintenance
Drain the condensation water regularly via the draining plug.
Possible causes
Ice formation in the pneumatic motor
Blunt cutting tool
Fall in pressure
Dirt, rust or worn lamellae in the
pneumatic motor
Advancement too fast or material removal
too high during one revolution
Oil loss in the gear box
Damaged chain link
Chain incorrectly joined
Chain bolt only partially inserted
Pipe milling machine and chain are not cor-
rectly aligned
Guide shaft not eccentric
Blunt cutting tool
Pipe is laid at an incline or vertical,
or pipe is out of round
Cutting tool is overloaded
Insufficient or no compressed air
Lamellae are worn
Motor is insufficiently lubricated
Coupling slips
Advancement too fast
Cutting tool too deep
Nuts (11) have not been tightened
Chain loose
Blunt cutting tool
Measures to be taken
Use special lubricant
Change the cutting tool
Check the compressed-air supply (6 bar)
Send the motor to the FEIN repairs
Align the gears and/or reduce the plunging depth
Replenish oil. If oil loss occurs again,
look for leakage point and repair.
Change the chain link
Check the joins and correct
Fully insert the bolt
See Chapter „Preliminary work on the pipe milling machine
(see Fig. A)." auf Page 19 and Abschnitt „Clamping the pipe
milling machine onto the pipe." auf Page 19
Adjust the running accuracy, see Chapter „Setting the run-
ning accuracy." auf Page 20
Change the cutting tool
Use the track guiding device, see Chapter „Clamping the
pipe milling machine onto the pipe." auf Page 19 und Chap-
ter „Track guiding" auf Page 27
Align the gears and/or reduce the plunging depth
Check the compressed-air unit for deficiencies or obstacles
Change the lamellae
Check the oil level in the maintenance unit
Align the gears or request the FEIN factory to adjust the
pick-up torque of the coupling
Align gears
Raise the cutting tool
Tighten nuts
Check chain tension
Change the cutting tool
Cleaning
Release the maintenance unit of pressure and loosen the container
from the bayonet lock. Loosen the impingement disc and take out the
filter insert; clean the filter insert or replace it by a new one. Screw filter
in ensuring O-ring is mounted. Mount container to bayonet lock.
H
Avoid damage!
Plastic containers (polycarbonate) must only be cleaned with water or
benzine used for cleaning purposes.
No liability can be assumed for damage caused due to non-adherence to
these instructions.
