eng
suitable for dealing with tight bends or several bends in succession. For obstruc-
tions presenting particular problems, e.g. when it is necessary to slice through
roots, the drain cleaning cable type S, made of heavier gauge wire (accessory),
is recommended. The cable with a core (accessory) contains a weather- and
temperature-resistant plastic core which prevents dirt from collecting inside the
cable or long fibres from lodging in the spirals.
2.3. Selection of suitable 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 flow of w ater.
2.3.2. Bulbous auger
Used for minor obstructions caused by textiles or paper, due to its high flexibility.
The extended club-type head facilitates advancement in tight bends.
2.3.3. Funnel auger
Used for textile and paper obstructions in particular. Is especially useful for
cleaning 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
Used to recover cables left in the pipe by means of an 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. This 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). This tool is riveted to the connector
(not soldered or welded), so as to prevent any deformation of the hardened
spring steel blades.
2.3.7. Forked cutters
Size 16 with one blade as a forked cutter or two blades as a cross-forked
cutter, made of hardened spring steel and designed 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. to remove 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.
2.3.9. Chain flail
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) as the final drain cleaning
operation. The version with smooth rings should be used for breakable pipes
made of e.g. plastic, while the version with spiked links should be used for cast
or concrete pipes.
3. Operation
3.1. Investigation of the obstruction
Position the machine 30 – 50 cm in front of the opening giving access to the
affected pipe.
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 a length of cable (5) into the machine, with the grooved part of the connector
(8) leading, until approximately 50 cm projects from the machine. Never connect
more than one length of cable at a time. Connect the drain cleaning tool (6) to
the free end of the cable, i.e. insert sideways into the T-groove of the cable
connector until it locks home. Use the straight auger as the first tool. Introduce
the tool and cable into the pipe. Switch on the machine with the switch (3) set
to rotate clockwise (switch position „1"). Draw the cable manually out of the
machine and feed it into the pipe until the cable develops a bend.
WARNING
Wear a suitable glove!
With the other hand, press down hard on the carrying handle (4) until the cable
rotates. Spring force applied to the cable produces the necessary thrust. When
the bend has straightened, pull the handle (4) upwards. The cable will imme-
diately come to a standstill. Feed in the cable manually again until a bend
develops, then apply firm pressure to the handle (4) until the bend straightens.
Keep repeating this procedure. Connect up further lengths of cable as neces-
sary until it reaches the obstruction and clears it. When it reaches the obstruc-
tion (resistance), it is important to ensure that it is advanced with care (one
centimetre at a time). If it seizes, the handle must be pulled upwards immediately,
otherwise the cable may break.
However, if a tool has become blocked by an obstruction, it should be freed by
the repeated reversal of the direction of rotation of the machine, i.e. anticklock-
wise (switch position „R") and clockwise (switch position „1"). Use the anticlock-
wise setting only for this process. All other operations including the recovery
of the cable are carried out in the clockwise direction.
3.2. Recovering the cable
Recovery of the cable takes place in the clockwise direction. Withdraw the
rotating cable from the pipe until it develops a bend. Release the pressure from
the handle (4) and push the cable back into the machine. Press down on the
handle and withdraw more cable from the pipe until it again develops a bend.
Repeat this process until a length of cable has been completely fed into the
machine or guide hose and it can be disconnected from the following length of
cable. Remove disconnected lengths of cable from the machine and guide
hose. Repeat this process until the entire length of cable has been removed
from the pipe.
3.3. Cleaning the pipe
From an examination of the contamination affecting the withdrawn straight
auger, it is generally possible to form conclusions as to the cause of the obstruc-
tion and therefore to select a suitable tool (see 2.3) with which the entire cross
section of the pipe can then be completely cleaned.
3.4. Adapter drum with 8 mm cable (accessory)
Remove the chuck mount guard (2) and cable guide hose (1) and replace them
with the adapter drum (Fig. 3 (10)) with the 8 mm diameter cable. The adapter
drum incorporates a collet for the 8 mm diameter cable. The operating proce-
dure with this cable is the same as that for the 16, 22 and 32 mm diameter
cables.
4. Maintenance
DANGER
Pull out the mains plug before carrying out maintenance or repair work!
This work may only be performed by qualified personnel.
4.1. Maintenance
The REMS Cobra is maintenance-free. The bearings of the drive shaft run in
a permanent grease filling and therefore require no lubrication. Clean pipe and
drain cleaning cables after each use.
4.2. Inspection/Upkeep
This work may only be carried out by qualified personnel and with original spare
parts.
5. Trouble
5.1. Trouble: Cable is not rotating despite of pressed down pressure loading
handle.
Cause:
● Tool got stuck at an obstruction (see 3.1.).
5.2. Trouble: Cable left in the pipe.
Cause: ● Connector was not closed.
● Broken cable.
6. Disposal
The units may not be thrown into the domestic waste at the end of use. They
must be disposed of properly by law.
