SAFETY
www.cobratools.com
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your
mains-operated (corded) power tool or battery operated
(cordless) power tool.
Work area safety
• Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
• Do not operate power tools in explosive
atmospheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
Electrical safety
• Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools.
Unmodied plugs and matching outlets will reduce risk
of electric shock.
• 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.
• Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
• Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
the risk of electric shock.
• When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risks of
electric shock.
• If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter
(GFCI) protected supply. Use of a GFCI reduces the
risk of electric shock.
Power tool use and care
• 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.
• 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.
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your nger on the
switch or energizing power tools that have the switch
on invites accidents.
• 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.
• Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long hair
can be caught in moving parts.
• If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
• When lifting heavy objects, always lift with your
knees, never with your back. Consider using two-
people when lift is heavy and/or awkward.
Proper Machine Operation
• Cleaning chemicals can be present in clogged
drains. If you have previously used chemicals or are
unsure, take care to avoid contact with the cable or
debris found in the drain.
• Machine is designed to be used by one person only.
The operator must control both the cable and the foot
switch. Should the cutter stop rotating, the operator
must be able to quickly stop the motor. This helps to
prevent kinking and breaking of the cable which could
cause crushing or striking injuries.
• Do not allow the cable to twist, kink or build up
tension. Do not let the cable endure overstressed
situations. This could potentially result in crushing and/
or striking injuries and unpredicted cable reactions. If
the cable starts to become overstressed, immediately
turn the machine off by taking your foot off the switch
and rotate the cable in the opposite direction until the
twist or buckle has been removed.
• Do not operate machine with motor in reverse.
Reverse is only used when the cable is stuck or
overstressed. Running the machine in reverse could result
in possible kinked or stressed cable and personal injury.
• Never retract the cable from the inlet while drum
is spinning. The cable could whip around and cause
serious personal injury or death.
WARNING indicates a hazardous
situation that, if not avoided, could result in death or
serious injury.
www.cobratools.com
• Disconnect the plug from the power source and/or
the battery pack from the power tool before making
any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
• 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.
• 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
before use. Many accidents are caused by poorly
maintained power tools.
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
• 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 than those intended could result in a
hazardous situation.
Service
• Have your power tool serviced by a qualied repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.

If your machine is not properly operating, do not use it
until the machine is properly repaired.
Do not allow the cable to twist, kink, buckle, become
overstressed or stuck. If the cable begins to get stuck
or buckle/ twist, immediately remove your foot from
the foot switch while rmly holding the cable with
both hands. Allow the machine to come to a complete
stop and the tension to release from the cable. Turn the
machine off and immediately manually rotate the cable
in the opposite direction until the twist or buckle has
been removed.
If the cutter is stuck in the clog, turn the machine into
the OFF position, then to REV and slowly press the foot
switch. Let the machine run slowly in reverse, stopping
the motor often to check if the cutter has become
released by manually retrieving the cable into the
drum. ONLY run the motor in REV if the cutter has
become caught. If the cable begins to get stuck or
buckle/kink/ twist, immediately remove your foot from
the foot switch while rmly holding the cable with
both hands. Allow the machine to come to a complete
stop and the tension to release from the cable. Turn the
machine off and immediately manually rotate the cable
in the opposite direction until the twist or buckle has
been removed.
Fingers or other body parts can be caught in rotating
parts and crush. Do not wear loose clothing, neck ties,
unbuttoned jackets, rings, watches or jewelry and always
tie back long hair. This will help reduce the risk of
entanglement with moving parts.
This machine has manual cable feed and it does NOT
automatically extend or retract the cable into the machine.
Cable MUST be fed by hand. You will use the machine
to clear obstructions, return to hand feeding the cable in
between clogs or joints.
1. Plug the machine into a properly grounded outlet.
Leave the motor in the OFF position.
2. Loosen thumbscrew and pull sufcient cable out of
the drum and place the end of the cable as far into the
inlet as possible. The machine should be NO MORE
THAN 2 FEET from the drain opening, with around 4
feet of uncovered cable between the drain opening and
drum opening. The cable should form a slight arch.
NEVER FORCE cable down the line. When the cable
will not feed further into the drain pipe, the cable is
probably stuck against an elbow or joint in the pipe or
may have reached the clog.
Do not continue to force cable into the
drain pipe. This can cause the cable
to twist, buckle, kink or break.
3. Tighten thumbscrew.
4. Place the motor in the forward (FOR) position and
slowly depress the footswitch to start the machine.
The drum will begin to turn as will the cable.
5. While depressing the foot switch, apply slight pressure
to the top of the arch of cable with both gloved hands.
If your cutter is at an elbow, this will help the cutter
“jump” the elbow, freeing it to continue through the
drain. If your cutter is at the clog, the cable will not
feed further.
6. Continue steps 2-5 until you have reached your clog.
7. Let the cutter do the work. Do not use too much force.
Do not continue to force cable into the drain pipe. This
can cause the cable to twist, buckle, kink or break.
Continue applying pressure to the arch of the cable until
the cutter has cleared past the clog.
Do not allow the cable to twist, kink, and buckle,
become overstressed or stuck. If the cable begins to
get stuck or buckle/twist, immediately remove your
foot from the foot switch while rmly holding the
cable with both hands. Allow the machine to come to
a complete stop and the tension to release from the
cable. Turn the machine off and immediately manually
rotate the cable in the opposite direction until the twist
or buckle has been removed. If the cutter is stuck
in the clog, turn the machine into the OFF position,
then to REV and slowly press the foot switch. Let the
machine run slowly in reverse, stopping the motor
often to check if the cutter has released by manually
retrieving the cable into the drum. ONLY run the motor
in REV if the cutter has become caught. If the cable
begins to get stuck or buckle/kink/twist, immediately
remove your foot from the foot switch while rmly
holding the cable with both hands. Allow the machine
to come to a complete stop and the tension to release
from the cable. Turn the machine off and immediately
manually rotate the cable in the opposite direction
until the twist or buckle has been removed.
If drum continues to rotate under power when the
cable/cutter is stuck, the cable can twist, buckle, kink
or break.
