The indicated weighted effective value of acceleration has been measured
against standard test procedures and can be used by way of comparison with
another device. The indicated weighted effective value of acceleration can also
be used as a preliminary evaluation of the exposure.
CAUTION
CAUTION
The indicated weighted effective value of acceleration can differ during operation
from the indicated value, dependent on the manner in which the device is used.
Dependent upon the actual conditions of use (periodic duty) it may be necessary
to establish safety precautions for the protection of the operator.
2. Start-up
2.1. Electrical connection
WARNING
Caution: Mains voltage present! Before connecting the electric pipe and drain
cleaning machine, check whether the voltage given on the rating plate corre-
sponds to the mains voltage. Only use sockets/extension leads with a functioning
protective contact.
The function of the fault current circuit breaker PRCD (11) must be checked
every time before starting up and starting work:
1. Plug the mains plug into the socket.
2. Press the RESET button (12), the PRCD control lamp (14) lights red
(operation).
3. Pull out the mains plug, the PRCD control lamp must go out.
4. Plug the mains plug back into the socket.
5. Press the RESET button (12), the PRCD control lamp lights red (operation).
6. Press the RESET button (13), the PRCD control lamp must go out.
7. Press the RESET button (12), PRCD control lamp lights red.
REMS Cobra is now ready for operation.
NOTICE
The plug or connecting cable (15) may only be replaced by an authorised REMS
contract customer service workshop.
WARNING
If the described functions of the PRCD fault current circuit breaker are not
fulfi lled, the device may not be used. There is a danger of electric shock. The
PRCD fault current circuit breaker tests the connected device, not the installa-
tion before the socket nor interconnected extension leads or cable reels.
On building sites, in a wet environment, indoors and outdoors or under similar
installation conditions, only operate the electric diamond core drilling machine
on the mains with a fault current protected switch (FI breaker) which interrupts
the power supply as soon as the leakage current to earth exceeds 30 mA for
200 ms. When using an extension lead, a cable cross-section suitable for the
power of the electric cleaning machine must be chosen. The extension lead
must be approved for the protection class specifi ed in 1.5 Electrical data.
2.2. Handling and selection of the pipe and drain cleaning cable
CAUTION
CAUTION
Follow the instructions for tool changing!
The indicated weighted effective value of acceleration can differ duriThe REMS
Cobra machines use lengths of cable which can be connected up as necessary.
The REMS Cobra 22 machine comes either with the cable and tool set 16 or
22 or both. The REMS Cobra 32 machine comes either with the cable and tool
set 22 or 32 or both. The pipe and drain cleaning cables can each be used
without modifi cations to the machine.
For the REMS Cobra 32 machine, the cable and tool set 16 can also be used
when using other clamping jaws 16 (accessories). To do this, remove the guard
(2). Push in the spring sleeve until it touches using a screwdriver. Push the
whole clamping jaw forward and lift out backwards over the parallel pin. Fit
clamping jaw 16 (set). To do this, push the clamping jaw 16 into the system
bearer, push in the spring sleeve until it touches and push the clamping jaw
over the parallel pin.
The pipe and drain cleaning cables are specially hardened and highly fl exible.
They can be extended or shortened very quickly by T-groove safety connectors.

Push the T-bar (7) sideways into the T-groove (8) to do this. The spring-loaded
thrust pin on the bar side locks the two halves together. To separate them, push
back the spring-loaded thrust pin with the cable joint separator (9) and push
the T-bar out of the T-groove. The pipe and drain cleaning cables and pipe and
drain cleaning tools will also fi t other makes of drain cleaning machines. An
adapter drum with a cable Ø 8 mm, length 7.5 m is available as an accessory
for every REMS Cobra 22 and REMS Cobra 32 (see 3.4.).
NOTICE
Do not use pipe and drain cleaning cables with a damaged spring-loaded thrust
pin. The T-bar coupling may not be pushed by hand without cable joint separator
(9) out of the T-groove coupling (8) after locking. The joint could otherwise be
pulled apart during the cleaning process in the pipe by twisting of the pipe and
drain cleaning cable and the pipe and drain cleaning tool. The pipe and drain
cleaning cable and/or pipe and drain cleaning tool then stay in the pipe.
The size of the cable required depends on the diameter of the pipe to be
cleaned. See 1.3 for guidance.
The type of cable to be selected depends on the length and position of the
pipe to be cleaned as well as on the type of obstruction expected. The standard
pipe and drain cleaning cable is used for universal pipe and drain cleaning
operations. Being highly fl exible, it is particularly suitable for dealing with tight
bends or several bends in succession. For obstructions presenting particular
problems, e.g. when it is necessary to slice through roots, the pipe and drain
cleaning cable S with thicker cable wire (accessory) is to be recommended. A
weather and temperature-resistant plastic core is incorporated into the pipe
and drain cleaning cable with core (accessory) which prevents dirt from collecting
inside the cable or long fi bres from lodging in the spirals.
2.3. Selection of suitable pipe and drain cleaning tool
2.3.1. Straight auger
Used as the starting tool to withdraw a sample from which the cause of the
obstruction can be determined. Also to clear a solid blockage caused by textiles,
paper, kitchen waste etc. to permit the fl ow of water.
2.3.2. Bulbous auger
Used for minor obstructions caused by textiles or paper, due to its high fl exibility.
The extended club-head facilitates advancement in tight bends.
2.3.3. Funnel auger
Used for textile and paper obstructions in particular. Is especially useful for
larger diameter pipes due to its generous radius of action. Can also be used
as a recovery tool for cables left in the pipe.
2.3.4. Retrieving auger
Use for retrieving pipe and drain cleaning cables left in the pipe. With extended,
specially angled grappling arm. Not suitable for boring operations.
2.3.5. Serrated blade borer
Used to bore out greasy or heavily silted pipes. The tool is riveted to the
connector (not soldered or welded) so as to prevent any deformation of the
hardened spring steel blades.
2.3.6. Serrated cross-blade borer
Multi-purpose tool for obstructions of all kinds, including incrustations (e.g.
limescale deposits on the inside of the pipe). The tool is riveted to the connector
(not soldered or welded) so as to prevent any deformation of the hardened spring
steel blades. Recommended for use with pipe and drain cleaning cables S.
2.3.7. Forked cutter
Size 16 with one blade as a forked cutter, with two blades as a cross-forked
cutter, made of hardened spring steel to remove moderate to severe silting or
persistent grease contamination. Size 22 and 32 with serrated, replaceable
blade as a serrated forked cutter, made of hardened spring steel, and with
multiple uses, e.g. for clearing silting or to reduce (break down) root infestation.
2.3.8. Root cutter
Tool with hardened, replaceable ring-type saw, cutting to the front and rear.
Specially designed for root infested pipes. Recommended for use with pipe
and drain cleaning cables S.
2.3.9. Chain fl ail
The most important tool of all for the removal of greasy deposits and incrusta-
tions (e.g. limescale deposits on the inside of the pipe). Chain fl ails with smooth
rings for breakable pipes, e.g. plastic. Chain fl ails with spiked links for cast iron
or concrete pipes.
3. Operation
3.1. Investigation/removal of the obstruction
Position the electric pipe and drain cleaning machine 30 – 50 cm in front of the
opening of the pipe to be cleaned.
Check to ensure that the guard (2) has been installed on the chuck mount
together with the guide hose (1) for the cable. Install if necessary!
The guide hose prevents the cable from twisting if the tool becomes blocked,
as well as cushioning its vibrations and collecting any dirt it may have picked up.
Feed the drain cleaning cable (5) into the electric pipe cleaning machine with
the T-groove connector (7) leading until approximately 50 cm of the cable length
is protruding from the pipe cleaning machine. Never connect more than one
length of cable cable at a time. Connect the drain cleaning tool (6) to the free
end of the drain cleaning cable, i.e. push sideways into the T-groove of the
drain cleaning cable until the connector locks home. Use the straight auger as
