Troubleshooting (type RDG (**)).
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.
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.
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.
Fault Possible causes Measures to be taken
Motor and cutting tool stop
functioning Ice formation in the pneumatic motor Use special lubricant
Blunt cutting tool Change the cutting tool
Fall in pressure Check the compressed-air supply (6 bar)
Dirt, rust or worn lamellae in the
pneumatic motor Send the motor to the FEIN repairs
Advancement too fast or material removal
too high during one revolution Align the gears and/or reduce the plunging depth
Oil loss in the gear box Replenish oil. If oil loss occurs again,
look for leakage point and repair.
Defective chain wheel Damaged chain link Change the chain link
Chain incorrectly joined Check the joins and correct
Chain bolt only partially inserted Fully insert the bolt
Faulty cutting procedure Pipe milling machine and chain are not cor-
rectly aligned 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
Guide shaft not eccentric Adjust the running accuracy, see Chapter „Setting the run-
ning accuracy.“ auf Page 20
Blunt cutting tool Change the cutting tool
Pipe is laid at an incline or vertical,
or pipe is out of round 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
Cutting tool is overloaded Align the gears and/or reduce the plunging depth
The function of the machine is
reduced or ineffective Insufficient or no compressed air Check the compressed-air unit for deficiencies or obstacles
Lamellae are worn Change the lamellae
Motor is insufficiently lubricated Check the oil level in the maintenance unit
Coupling slips Align the gears or request the FEIN factory to adjust the
pick-up torque of the coupling
Strong vibrations Advancement too fast Align gears
Cutting tool too deep Raise the cutting tool
Nuts (11) have not been tightened Tighten nuts
Chain loose Check chain tension
Blunt cutting tool Change the cutting tool
