General Safety Instructions for power tools
WARNING
WARNING
Read all the s
afet
y notes, instructions, illustrations and technical data which
come with this power tool.
Failure to heed the following instructions can lead to
electric shock, fi re and/or severe injuries.
Keep all safety notes and instructions for the future.
The term "power tool" used in the safety notes refers to mains operated power tools
(with power cable).
1) Work area safety
a) Keep work area clean an
d w
ell lit.
Untidiness or poorly lit working areas can
lead to accidents.
b) Do not operate power tools in explosive atmospheres, such as in the pres-
ence of fl ammable liquids, gases or dust.
Power tools create sparks which
may ignite the dust or fum
es.
c) Keep children and bystanders away while operating a power tool.
Distrac-
tions can cause you to lose control.
2) Electrical safety
a) Power tool plugs mu
st match the outlet. Never modify the plug in any way.
Do not use any adapter plugs with earthed (grounded) power tools.
Unmod-
ifi ed plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces, such as pipes,
radiators, ranges and refrigerators.
There is an increased risk of electric shock
if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions.
Water entering a power
tool will increase the risk of electric shock.
d) Do not misuse the connecting cable to carry or hang up the power tool or
to pull the plug out of the socket. Keep the connecting cable away from
heat, oil, sharp edges or moving tool parts.
Damaged or knotted cables
increase the risk of electric shock.
e) When operating a power tool o
utdoors, use an extension cord suitable for
outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric
shock.
f) If operating a power tool in a damp location is unavoidable, use a residual
current device (RCD) protected supply.
Use of an RCD reduces the risk of
electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating
a power tool. Do not use a power tool while you are tired or under the infl u-
ence of drugs, alcohol or medication.
A moment of inattention while operating
power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection.
Protective
equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protec-
tion used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before
connecting to power
source, picking up or carrying the tool.
Carrying power
tools with your fi nger on the switch or energising power tools that have the switch
on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on.
A
wrench or a key left attached to a rotating part of the power tool may result in
personal injury.
e) Do not overreach. Keep proper footing and balance at all times.
This enables
better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing
or jewellery. Keep your hair,
clothing and gloves away from moving parts.
Loose clothes, jewellery or long
hair can be caught in moving parts.
g) Do not take your safety for granted and ignore the safety rules for power
tools even if you are very familiar with the power tool after frequent use.
Careless handling can lead to severe injury within split seconds.
4) Power tool use and care
a) Do not force
the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which it was
designed.
b) Do not use the power tool if the switch does not turn it on and off.
Any power
tool that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source before making any adjustments,
changing acces
sories, or storing power tools.
Such preventive safety meas-
ures reduce the risk of starting the power tool ac
cidentally.
d) Store idle power tools out of the reach of children and do
not allow persons
unfamiliar with the power tool or these instructions to operate the power
tool.
Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired by qualifi ed technical
personnel or an authorised REMS service shop before use.
Many accidents
are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to
be performed.
Use of the power tool for operations different from those intended
could result in a hazardous situation.
h) Keep handles and gripping surfaces dry, clean and free from oil and grease.
Slippery handles and gripping surfaces prevent safe handling and control of the
power tool in unforeseeable situations.
5) Service
a) Have your power tool serviced by a qualifi ed repair person using only
identical replacement parts.
This will ensure that the safety of the power tool
is maintained.

2. Start-up
2.1. Electrical connection
WARNING
WARNING
Caution: Mains voltage present!
Before connecting the power tool, check
whether the voltage given on the rating plate corresponds to the mains voltage.
On building sites, in a wet environment, indoors and outdoors or under similar
installation conditions, only operate the power tool on the mains with a fault
current protection switch (FI switch) which interrupts the power supply as soon
as the leakage current to earth exceeds 30 mA for 200 ms.
2.2. Mounting the pipe cleaning spiral in the spiral drum (10)
When a new pipe cleaning spiral is mounted, this must be bent approx. 45°
about 50 mm before the rear end of the spiral and then pushed through the
open chuck (5) / thrust gear (
11
) into the spiral drum so that the pipe cleaning
spiral winds up in clockwise direction looking though the end opening of the
spiral drum (10). Push in the pipe cleaning spiral until the club head (6) protrudes
approx. 200 mm from the chuck (5) / thrust gear (
11
).
3. Operation
3.1. Operation REMS Mini-Cobra
A
CAUTION
CAUTION
Only operate the electric pipe cleaning machine with both hands, always grip
the thrust handle (1) and switch handle (2) tightly.
Note reaction torque of the
drive unit on the spiral drum (10) when switching on and off! Start the electric
pipe cleaning machine preferably at low speed and increase slowly as required.
Pull out the pipe cleaning spiral Ø 8 mm or Ø 10 mm approx. 150 mm. For pipe
cleaning spiral Ø 8 mm, turn the thrust handle (1) to the stop, for the pipe
cleaning spiral Ø 10 mm until it meets a resistance and then turn it further
approximately one revolution. Set the direction of rotation switch (3) to the arrow
in the direction of the spiral drum (10) to feed the pipe cleaning spiral into the
pipe. The arrow direction corresponds to the feed direction of the pipe cleaning
spiral. With the adjusting wheel on the safety inching switch (4) the speed can
be limited from the lowest stage A to the highest stage F. Press the safety
inching switch (4) lightly so that the spiral drum (10) turns, then increase the
speed slowly as required. If the cleaning spiral meets a resistance, the speed
may have to be reduced or the electric pipe cleaning machine switched off, set
the direction of rotation switch (3) to the arrow in the direction of the switch
handle (2) so that the feed direction can be reversed. After clearing the blockage,
switch off the electric pipe cleaning machine, set the direction of rotation switch
(3) to the arrow in the direction of the swit6ch handle (2) to retract the pipe
cleaning spiral from the pipe. The electric pipe cleaning machine must be
switched off about 200 mm before the club head (6) reaches the thrust gear
(11). After cleaning work, the thrust handle (1) must be released for transport
and the pipe cleaning spiral must be pushed back by hand into the spiral drum
(10) up to just before the stop of the club head (6) on the thrust gear (11).
CAUTION
CAUTION
The pipe cleaning spiral can whiplash if the distance between the end of the
pipe/drain and the thrust gear (
11
) is too great (danger of injury)!
NOTICE
NOTICE
Only push the pipe cleaning spiral into the pipe to an extent that at least two
windings remain in the spiral drum (10) when cleaning. If the pipe cleaning
spiral is pushed further, the motor can no longer retract the spiral. The pipe
cleaning spiral then has to be pushed back into the spiral drum (10) about 2
windings by hand. Then the automatic return starts working again.
The club head (6) formed on the pipe cleaning spiral may never be allowed to
get into the thrust gear (
11
) because otherwise the pipe cleaning spiral will be
damaged.
3.2. Operation REMS Mini-Cobra
Pull the pipe cleaning spiral approx. 300 mm out of the spiral drum (10), tighten
the chuck (5) by hand and insert the spiral into the pipe to be cleaned. Hold
the handle (7) tight and turn the spiral drum (10) clockwise by turning the crank
(8) with your other hand. Only insert the pipe cleaning spiral into the pipe to an
extent that the chuck (5) can still be operated by hand. Open the chuck (5) and
pull the pipe cleaning spiral about 300 mm back out of the spiral drum (10).
Repeat the process until you can feel a resistance or the blockage is cleared.
Pull back the pipe cleaning spiral by hand and push it back into the spiral drum.
3.3. Operation of REMS Mini-Cobra with a suitable electric drill/electric screw-
driver
If an e
lectric drill/electric screwdriver is used to drive the REMS Mini-Cobra,

Pull the pipe cleaning spiral about 300 mm out of the spiral drum (10), tighten
the chuck
(5) by hand. Always start the electric drill screwdriver at low speed
in right right hand rotation and increase the speed as required. Only insert the
pipe cleaning spiral into the p
ipe to an extent that the chuck (5) can still be
operated by hand. Switch off the electric drill/screwdriver. Open the chuck (5)
and pull the pipe cleaning spiral about 300 mm back out of the spiral drum (10).
Repeat the process until you c
an feel a resistance or the blockage is cleared.
Keep a maximum distance of 200 mm between the end of the pipe/drain and
the chuck (5) otherwise the pipe cleaning spiral can loop. Always pull back the
pipe cleaning spiral by hand and push it back into the spiral drum. Only use
anticlockwise rotation of the electric drill/screwdriver if the pipe cleaning spiral
is jammed in the pipe. Switch the electric drill/screwdriver carefully between
clockwise and anticlockwise rotation to remedy this.
