The machine frame together with the axles has the task of guiding
the clamped-on pipe milling machine on the pipe, and transmitting
the forces for cutting and advancing. The alignment to the respec-
tive external diameter of the pipe is made by adjusting the running
axle (10). The clamping chains are composed of individual, identical
chain links that are joined together.
The number of the required chain links, i.e. the length of the clam-
ping chain, depends on the external diameter of the pipe.
Before putting into operation.
Preliminary work on the pipe to be machined.
Pipes that are cut in the warehouse must be supported underne-
ath such that the cutting tool does not wedge.
In the case of pipes that have been laid, a distance away from the
pit wall of at least 50 cm, measured from the outer side of the
pipe, must be given at any place over a length of 1 m.
The surface of the pipe must be free from any dirt or earth.
Remove any soft protective coating on the surface of the pipe.
The cutting tool must be selected according to the pipe material,
the required form of machining and the cooling lubricant.
For further information, please contact your coolant/lubricant sup-
plier (also see compressed-air cooling-lubricant device
9 12 01 002 00 4).
Preliminary work on the pipe milling machine
(see Fig. A).
Loosen the two nuts (11) lying opposite each other.
Raise the tool spindle holder (16) on the feed unit (7) using the
handwheel (in the carrying case).
Remove the tight-fit screws (9) and re-mount the running axle (10)
to the present external diameter of the pipe according to the
instructions on the specification plate (4). For intermediate sizes,
use the next largest external diameter of pipe. Tighten the tight-fit
screws (9) again.

Drive out the clamping fixtures (1) for the clamping chains by tur-
ning the sprung chain tensioner such that after placing the pipe mil-
ling machine on, sufficient clamping/tensioning distance is available.
Assemble the clamping chains to fit the external diameter of the
pipe. Position the pipe milling machine on the pipe.
Clamping the pipe milling machine onto the pipe.
Mounting the link chains.
Place the link chains (that still have open ends) on both sides of the
pipe milling machine, over the pipe.
Raise the pipe milling machine and push the link chains underneath
the chain wheels so that the link chains are in the mesh after the
pipe milling machine has been placed down. Place the link chains
with their open ends over the chain wheels of the clamping axle
(14) and running axle (10). Finally close using the bolt
(3 02 17 216 00 4) and secure with the 2 securing
rings (4 26 34 020 00 5).
Tensioning the link chains.
Mount the link chains loosely over the pipe first by turning both the
sprung chain tensioners. For exact alignment, push the pipe milling
machine backwards and forwards a few times along the circumfe-
rence of the pipe.
Tension the link chains by turning the sprung chain tensioners until
the pin (24, see Fig. A) juts into the elongated hole of the sprung
chain tensioner inside the groove punched in the circumference.
Watch the position of the pin during the cutting process. If the pipe
should prove to be out of round, either retension or loosen.
!
Do not continue to turn the sprung chain tensioner beyond this point!
Assembling the cutting tools.
!
by switching ON unintentionallyn.
Before assembly, remove the mains plug or the compressed-air hose.

the undervoltage trip disconnects the pipe milling machine from the

mains in order to prevent it from starting again unintentionally.
39.4 – 51.2
The pipe milling machine is put into operation again by actuating the
51.2 – 118.1
motor protection switch.
The switchgear combination is to be positioned such that it is acces-
sible for the operator at all times.

Danger of accidents!
Risk of injury
Before mounting, clean the tool spindle and also the fitting area
and contact surfaces.
Mount the cutting tool.
Tighten the tool tensioning nut.
The pipe milling machines with electric
drive have an upstream switchgear combi-
nation that contains the following compo-
nents:
-Main switch/reversing switch
-Motor protection switch
-Undervoltage release
-Plug connections
The main switch is used for switching on
and for reversing the direction of rotation.
The motor protection switch and the
undervoltage release form one unit. In the
case of overload, the motor protection
switch switches off; if there is a power cut,
In front of the switchgear combination use
a switch box with additional ON/OFF
switch for actuating the pipe milling
machine in areas in Zone 2 where there is
risk of explosion.
The switch box is to be positioned such
that it is accessible for the operator at all
times.
!
Danger of explosion
The switchgear combination is to be set
up outside Zone 2.
!
After actuating the automatic circuit
breaker, the auxiliary switch must be swit-
ched off first prior to switching on again.
