the fi rst tool. Introduce the tool and cable into the pipe. Switch the electric pipe
and drain cleaning machine to rotate clockwise (switch position ("1") at the
switch (3). Draw the pipe and drain cleaning cable manually out of the electric
pipe and drain cleaning machine and push it into the pipe to be cleaned until
it develops a bend.
WARNING
Wear a suitable guide glove!
With the other hand, press down hard on the carrying handle (4) until the pipe
and drain cleaning cable (5) rotates. Spring force applied to the cable produces
the necessary thrust. When the bend has straightened, pull the carrying handle
(4) upwards. The pipe and drain cleaning cable immediately comes to a stand-
still. Feed in the pipe and drain cleaning cable again manually until a bend
develops. Then apply fi rm pressure to the carrying handle (4) again until the
bend straightens. Keep repeating the procedure. Connect up further lengths
of cable as necessary until it reaches the obstruction and clears it.
When it reaches the obstruction (resistance), it is important that the pipe and
drain cleaning cable (5) is advanced with care (one centimetre at a time) . If
the pipe and drain cleaning cable seizes, the carrying handle (4) must be pulled
up immediately because the cable could otherwise break.
However, if a pipe and drain cleaning tool (6) has become blocked by an
obstruction, it should be freed by repeated, brief reversal of the direction of
rotation of the electric pipe and drain cleaning machine to anticlockwise (switch
position "R") and clockwise (switch position "1"). Use the anticlockwise setting
only for this process. All other operations including the recovery of the cable
are carried out in clockwise direction.
3.2. Recovering the pipe and drain cleaning cable
Recovery of the pipe and drain cleaning cable (5) also takes place in clockwise
direction. Withdraw the rotating pipe and drain cleaning cable from the pipe
until it develops a bend. Release the pressure from the carrying handle (4) and
push the pipe and drain cleaning cable back into the electric pipe and drain
cleaning machine. Press the handle again and draw the pipe and drain cleaning
cable out of the pipe until it has developed a bend again. Keep repeating the
procedure until a length of cable has been pushed completely into the electric
pipe and drain cleaning machine or guide hose and it can be disconnected
from the following length of cable. Remove disconnected lengths of cable from
the pipe and drain cleaning 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
obstruction and therefore to select a suitable tool (see 2.3) with which the entire
cross section of the pipe can then be completely cleaned.
5. Faults
WARNING
Switch off the switch (3) and pull out the mains plug before fi xing the fault!
5.1. Fault: Electric pipe and drain cleaning machine not working.
Cause:
● Fault current circuit breaker PRCD (11) is not switched on.
● Connecting cable (15)/PRCD defective.
● Electric pipe and drain cleaning machine defective.
5.2. Fault: Pipe and drain cleaning cable (5) does not rotate despite pressed carrying handle (4).
Cause:
● Tool got stuck at an obstruction.
● Clamping jaws defective.
5.3. Fault: Pipe and drain cleaning cable (5) and/or pipe and drain cleaning tool (6) stays in the pipe.
Cause:
● Connector was not closed.
● Spring-loaded thrust pin of the pipe and drain cleaning cable (5) of the T-bar
connector (7) defective.
● Bore for locking the spring-loaded thrust pin of the T-groove connector (8)
soiled/damaged.
● pipe and drain cleaning cable (5) broken.
3.4. Adapter drum with 8 mm pipe and drain cleaning cable (accessory)
Remove the guard (2) and guide hose (1). Fit the adapter drum (Fig. 3) (10)
with the Ø 8 mm pipe and drain cleaning cable in their place. The adapter drum
contains a clamping jaw set for the Ø 8 mm pipe and drain cleaning cable. The
operating procedure with this pipe and drain cleaning cable is the same as with
the Ø 16, 22 and 32.pipe and drain cleaning cables.
3.5. Taking out of operation and transport (Fig. 5)
Wind the guide hose (1) and mains lead (15) as described.. Fix the guide hose
(1) and mains lead (15) with the tightening strap (16) (accessory art. no. 131104)
to the carrying and pressure loading handle (4) and transport the device by the
carrying and pressure loading handle (4).
4. Maintenance
Notwithstanding the maintenance described below, it is recommended to send
in the power tool to an authorised REMS contract customer service workshop
for inspection and periodic testing of electrical devices at least once a year. In
Germany, such periodic testing of electrical devices should be performed in
accordance with DIN VDE 0701-0702 and also prescribed for mobile electrical
equipment according to the accident prevention rules DGUV, regulation 3
"Electrical Systems and Equipment". In addition, the respective national safety
provisions, rules and regulations valid for the application site must be considered
and observed.
4.1 Maintenance
WARNING
Pull out the mains plug before maintenance work!
REMS Cobra is maintenance-free. The bearings of the drive shaft run iln a
permanent grease bearing. The machine therefore requires no lubrication.
Clean the REMS Cobra, pipe and drain cleaning cables and pipe and drain
cleaning tools after every use, especially also the clamping jaws and the area
around the clamping jaws.. Also clean the T-bar (7) and T-groove (8) connectors
of the pipe and drain cleaning cables (5) and pipe and drain cleaning tools (6).
Clean the spring-loaded thrust pin of the T-bar (7) connector and check correct
function. Clean heavily soiled metal parts with the REMS CleanM (Art. No.
140119) cleaner, for example, and then protect against rust. Clean plastic parts
(e.g. housing) only with the REMS CleanM machine cleaner (Art. No. 140119)
or a mild soap and a damp cloth. Do not use household cleaners These often
contain chemicals which can damage the plastic parts. Never use petrol,
turpentine, thinner or similar products to clean plastic parts. Make sure that
liquids never get inside the electric pipe and drain cleaning machine. Never
immerse the electric pipe and drain cleaning machine in liquid.
4.2 Inspection/Maintenance
WARNING
Pull out the mains plug before maintenance and repair work! This work
may only be performed by qualifi ed personnel.
Remedy:
● Switch on fault current circuit breaker PRCD as described in 2.1.
● Have the connecting cable/PRCD replaced by qualifi ed technicians or an
authorised REMS contract customer service workshop.
● Have the pipe cleaning machine inspected/repaired by an authorised REMS
customer service workshop.
Remedy:
● Work the pipe and drain cleaning tool free by repeatedly switching the direction
of rotation briefl y from anticlockwise (switch position "R") to clockwise (switch
position "1") at the switch (3).
● Change the clamping jaws (see 2.2) or have them changed by an authorised
REMS customer service workshop.
Remedy:
● Check that the connector is tight after locking before use. Use a retrieving
auger to retrieve pipe and drain cleaning cable(s) (5) and/or pipe and drain
cleaning tools (6) left in the pipe.
● Change the pipe and drain cleaning cable.
● Clean bore or change pipe and drain cleaning cable (5) and/or pipe and drain
cleaning tool (6).
● Use retrieving auger to retrieve pipe and drain cleaning cable(s) (5) and/or pipe
and drain cleaning tools left in the pipe. Do not continue using broken pipe and
drain cleaning cables.
