RISK RANKING TABLE:
In the adjacent table, the
consequences, or ‘loss outcomes’ and
their related likelihood assist in accurate-
ly determining the risk ranking attribut-
able to each loss event. For example, a
consequence labelled as ‘Moderate with
a likelihood determined to be ‘Likely’,
yields an effective risk ranking of 17.
The table exhibits a risk ranking,
ranging from 1 to 25, relevant to each set
of probabilities and consequences. A
ranking of 25 constitutes a highly likely,
and thus very serious, event.
Consequently, a ranking of 1 signies the
lowest possible degree of risk, meaning
that particular event is very unlikely to
occur.
Specic controls must be taken in order
to mitigate risk, and where possible,
eliminate it completely.

We would like to ensure that you not only obtain the
best possible results from your new machine, but that
you also, more importantly, operate it in a safe and
comfortable manner. In an effort to achieve this ob-
jective, this manual contains information on how to
do so most effectively. We ask that you please read it
carefully, and understand it clearly, before
operating your machine.
Additionally, please note that the drain and sewer
cleaning procedures must be followed diligently. If
not, this could result in severe injury, and in some
cases, death. Appropriate safety clothing and equip-
ment must be used at all times.
Drain cleaning jetters utilise water at extremely high
pressures in order to clear blockages
containing inevitable build up, such as grease,
sediment and tree roots, from clogged rains. The pres-
sure is generated by restricting the ow of
water with a nozzle at the end of an extremely exible
jetting hose.
The nozzle contains reverse facing,
high-pressure, jets of water, and works to
propel the hose along the drain, effectively clearing
blockages, and ushing away the remaining debris.
FROST PROTECTION
If your environment increases the danger of the water
freezing, the jetter and hose must be completely drained, or the system
thoroughly ushed with antifreeze, as follows:
1. Run the machine until the oat tank is almost empty.
2. Fill with 50% mix of water and antifreeze and run the pump until
antifreeze appears at the high-pressure outlet.
WARNING: Do not use the jetter if there is a chance that ice has formed
within the hose or pump.
4

SAFETY PRECAUTIONS
All individuals operating a high-pressure jetter must ensure
that they are competent in doing so. To provide some basic
guidance, we recommend the following precautions:
1. Never direct the spray jet at any person(s) or
animal(s).
2. Never direct the spray jet at any surface that may
contain asbestos.
3. Do not operate the jetter with a nozzle attached to
the hose while the end of the hose sits outside of
the pipe as the hose will whip out of control and likely
cause injury.
4. Never hold a nger over the high-pressure
nozzle as one’s skin may be penetrated by the
high-pressure water jets.
5. Never direct the spray jet at the machine itself, or
any electrical equipment.
6. After use, release the pressure in the high-pressure
hose by operating the hose reel ball valve, or gun
trigger if operating a gun/lance.
7. Whilst not operating, always switch off the engine,
depressurise all hoses, and disconnect the machine
from the water supply.
8. Certain engine components become extremely
hot when in use, such as the exhaust mufer and the
cylinder head. Thus, switch off the engine and
ALLOW TO COOL before touching or refuelling.
9. Do not attempt any mechanical repair on the
machine. If you do have a problem with your
machine, please contact ROTHENBERGER or their
nominated service agent.
10. Never supply any liquid, other than clean water, to
the water inlet.
11. Never pull the high-pressure hose if it has formed
kinks or nooses. Additionally, never pull the hose
over sharp objects and do not allow the hose to be
driven over. A damaged hose must be
professionally repaired or immediately replaced. Be
sure to visually check all hoses prior to each and
every use.
12. Do not join any jetting hoses together as couplings
may fail or get jammed within the drains.
13. Use your machine only in a well-ventilated area.
14. Ensure the unit remains level during operation, as
low oil levels may lead to engine damage.
15. Do not attempt to disconnect any hose or
coupling whilst pressurised.
16. Do not operate the machine when standing
on ladders. Rather, use a platform tower or
scaffolding.
17. Wear safety goggles when operating the
machine, particles of stone, grit, or other
related substances may be blown around by
high-pressured spray.
19. Remain alert and forever pay attention to
what you are doing and to the machine that
you are operating. Do not use the jetter
while you are tired or under the inuence of
drugs, alcohol or any medication that may
impair judgement.
WORK AREA SAFETY --- MINIMISE HAZARDS
1. Keep your work area clean and well lit.
2. Set-up the jetter and establish your work
area in such a way as to minimise the risk
of injury from high-pressured water, chemical
burns, infections, carbon monoxide, and
other dangers.
3. Mark off the area, with physical barriers
where necessary, in order to keep bystanders,
passing trafc and non-essential personnel
clear and safe.
4. Check for ammable or poisonous liquids,
vapours and dust that have the potential to
ignite. Do not operate the jetter until the
area has been cleaned, and thus deemed to
be safe for operation.
5. Check the condition of the drains before
starting to jet. Drains that are in good
condition will not be damaged by the jetting
process. However, poorly maintained or
constructed drains are highly susceptible to
further damage, and these conditions may
mean that the jetting is far less effective.
RISK ASSESSMENT
COMPLETE A RISK ASSESSMENT OF THE SITE & JOB
BEFORE YOU START.
Please see risk assessment checklist for jetting
equipment on page 3.

SAFE JETTING
STAY SAFE
SAFETY CLOTHING
It is vitally important that all persons operating the unit
must wear protective clothing, such as safety goggles,
face shields, gloves, overalls or raincoat, steel capped
boots as well as ear protection equipment as applicable.
Please refer to page 12 for further details.
ENGINE HAZARDS
Engines emit a toxic, carbon monoxide gas, that is both
colourless and odourless. Therefore, you must not
operate the jetter within an enclosed area.
Petrol is an extremely volatile, ammable and explosive
substance when in the midst of certain environments. In
order to effectively mitigate these risks, please adhere
to the following guidelines:
• Turn off the engine and allow the
mechanism to cool before refuelling.
• The refuelling of the unit must be
completed in a careful and conscious
manner. Please be sure to not overll the
tank, and use suitable equipment when
carrying out this task, such as appropriate
containers and funnels. Once the unit has
been refuelled, ensure that the fuel tank lid
is correctly closed and secured.
• Carefully check for and clean away any
spills before starting the engine.
NOTE various parts of the engine will become hot
whilst operational. These extremely hot surfaces can
cause direct burns and lead to larger res. Hence, you
must ensure that all body parts are kept at a comfort-
able distance away from the hot areas of the engine.
Additionally, remain conscious of the fact that these
engine parts will take some time to cool down. For
more information, please refer to page 3.
JETTER WARNING
Before commencing the operation of your drain
cleaning jetter, ensure that you have read and fully
comprehend this manual:
Note: Certication of the operator is mandatory for
Class B machines - refer to AS/NZS4233.1.
WASH DOWN OPERATION
Never spray any person(s) or animal(s) whilst
operating your jetter with the wash down gun/
lance. To do so would likely result in the severe
injury or death of those sprayed.
BACTERIA WARNING
Sewer lines and drainpipes alike are susceptible
to the often-inevitable build-up of bacteria and
various other dangerous micro-organisms, which
may prove infectious. If exposed to one’s mouth,
nose, ears, eyes, hands, open cuts or any type of
abrasion, this can lead to severe illness or death.
In order to adequately protect the operator
against such threats, it is crucial that one’s arms,
hands, and other areas of the body are thorough-
ly washed with hot and soapy water immediately
after any involvement with sewer lines. For fur-
ther information, please refer to page 3.
Never eat or smoke whilst operating the jetter, as
this may leave you vulnerable to the transfer of
harmful micro-organisms.
The jetting hose has been purposefully marked
at 1 metre from the end of the hose in an effort
to ensure that the operator is notied when he
or she is nearing the end of the jetting hose as it
is being drawn from the drain or sewer line. The
operator must shut off the water pressure owing
to the nozzle before removing the last metre of
jetting hose from the sewer line or drainpipe.
Failure to follow these guidelines may result in
sever injury or death.

and engine daily.
NOTE there are separate oil reservoirs for the pump and
engine.
2. With the machine placed upon a level surface, the
pump oil level should cover the red dot located in
the oil level sight glass on the side of the pump.
If necessary, top-up the oil level (use non foaming type
of oil [refer to pump manufacturers manual]). Be very
careful to not mix different oil grades as this may prove
detrimental to the machine’s performance. If you are
planning to use alternative oil, be sure to rst empty
the remaining oil by unscrewing the drain plug at the
bottom of the pump.
3. After lling the oil to an adequate level, ensure that
the breather plugs is tted back to the pump.
4. Remember to carefully check the engine’s oil level on
a daily basis. Please refer to the engine
manufacturer’s separate handbook for further
guidance.
START UP PROCEDURE
1. Pull a sufcient amount of water supply hose
off the reel and connect this to the water tap.
NOTE the break tank is tted with a low water cut
off switch. This means that the engine will not run
if the water level drops below a certain point.
2. Turn on water supply
NOTE the tap should be fully on. Please ensure
that there are no leaks throughout the supply
hose and/or connections.
3. Ensure that the break tank is full, and the oat
valve has shut off.

ROTHENBERGER SAFETY PROTECTION
SAFETY VALVE :This device protects the pump
as it releases excessive pressure if the unloader has
been tampered with.
Please do not tamper with the preset unloader and
safety valve. It is very dangerous to do so and will
void your warranty.
ALTERING PUMPING SYSTEM MAY
RESULT IN SEVERE INJURY OR DEATH
Warranty will be void if any high-pressure equipment
has been altered by unauthorised persons. Over-speed-
ing or over-pressurising of the pumping system can be
extremely dangerous and will signicantly reduce the
life of your Draining Cleaning Jetter. It may also result
in injury or death.
ROTHENBERGER SAFETY PROTECTION
Your high-pressure pumping system operates as the
heart of your drain cleaning jetter. Accordingly, the
Pump has been specically designed to operate with
cold water for pipe water jetting and high-pressure
wash down applications.
High-pressure is created when the pump outlet is
restricted with a nozzle. All high-pressure outlet
connections, hosing and equipment is rated well above
the maximum operating pressure of the pump.
Please be sure to never adjust the regulators on your
pump. Doing so will void your warranty. Additionally,
for any high-pressure pumping system malfunctions,
please contact ROTHENBERGER, or an approved and
qualied service centre.
Due to the obvious safety hazards that accompany the
operation of high-pressure systems, be sure to use only
approved and genuine high-pressure hoses and
components when replacing or repairing your drain
cleaning jetters. For further guidance around this,
please contact ROTHENBERGER or the Distributor from
whom you purchased your unit.

SAFE JETTING
PERSONAL PROTECTIVE EQUIPMENT
Appropriate personal protective equipment
should be worn where:
• Hazards cannot be prevented or otherwise suitably
controlled, e.g. by engineering or administration
controls, total enclosure or substitution.
• Complete protection is essential, e.g. in certain
occupational environments containing hazardous
levels that are uncertain
• Please note that the provision and use of certain
personal protective equipment certainly does not
reduce or replace the necessity of proper
Occupational Health and Safety prevention measures,
such as engineering or administrative controls, to be
exercised. Such preventative measures should always
be fully explored and implemented where applicable,
well before considering the utilization of
personal protective equipment. Where personal
protective equipment is deemed necessary, and thus,
issued, proper instruction and adequate training must
be provided regarding its correct use and
maintenance.
Head Protection
Where appropriate suitable head protection
complying with AS/NZS 1801 should be worn.
Eye Protection
In compliance with AS/NZS 1337, eye protection,
adequate for both purpose and individual t, should
be worn at all times when in the vicinity of any water
blasting operations. Where the liquid is likely to cause
eye damage, and thus, the individual operator is
vulnerable, full visor and goggles are recommended.
Body Protection
In compliance with AS/NZS 3765.1 (or AS/NZS 3765.2 if
working with hazardous chemicals) all persons should
wear suitable waterproof clothing, applicable to the
nature of work being done. Specically, liquid or
chemical-resistant suits should be worn where there
is an assessed risk to health or of injury that can be
prevented by such equipment.
Hand Protection
In compliance with AS/NZS 2161.2, AS/NZS 2161.3 or
AS/NZS 2161.5, appropriate hand protection should be
worn where there is an assessed risk of injury that can
be prevented by such equipment.
Foot Protection
In compliance with AS/NZS 2210.2, appropriate
occupational footwear should be worn at all times.
Furthermore, a lower leg guard should be used by
water blasting operators where it has been assessed
that the risk of foot injury could be prevented by such
equipment. Please refer to AS/NZS 2210.2 for guidance
around the appropriate selection of footwear.
Hearing Protection
In compliance with AS/NZS 1270, appropriate hearing
protection should be worn at all times where the level
of noise exceeds the limits stipulated by regulatory
authorities.

OPERATING TIPS
We would like to provide you with some tried and
tested tips and techniques to make your jetting
experience an easier and more enjoyable one.
• Be sure to always use the safety plate as it will protect
your jetting hose against damage from both sharp
edges and rough surfaces present at the entrance
to the drain. Remember, more damage is done to a
hose upon the entering and exiting of the drain than
anywhere else. Additionally, the safety plate prevents
the jetting nozzle from accidentally existing the drain
whilst under pressure.
• Begin your jetting with a long nozzle, such as the
Predator, or for smaller drains, such as the
Compressor.
• To combat extremely tight bends, remove the quick
coupler from the hose, the cowling from the nozzle,
and connect the head directly to the hose.
• Twist your jet hose in order to effectively manoeuvre
it around tight bends and traps
• Once you have broken through the blockage, change
to the Root Ranger in order to clear the tree roots
from the sides of the drain. Additionally, when using
the Root Ranger Turbine, the hose must be twisted in
order to thoroughly clear the root choke from all
sides of the pipe.
• To prevent the Root Ranger Turbine from entering
side channels, simply push through the junction
as quickly as possible, without twisting it. Doing so
will maintain the turbine on a straight path.
• If your hose happens to become jammed, which is a
fairly common occurrence, pull the hose hard and
then let it go quickly so that it may snap back and
loosen itself. Additionally, turn off the jet, pull the
hose, and then turn the jet back on once more.
• When accessing a square junction down a shaft, a
section of 50mm of pipe with an elbow on the end
may help direct your nozzle up and into the desired
location. Alternatively, you may run your hose
through a section of exible pipe, such as a 50mm ag
drain, in order to assist in the directing and
protecting of the jetting hose.
While the Root Ranger is considered top of the line,
it will become stuck on a regular basis. In an effort to
mitigate this:
• Attempt running the Root Ranger straight towards
the blockage, without twisting the hose.
• Delay the twisting of the hose to when you are
actually cutting the roots or retrieving the hose from
the blockage. Such a practice will stop it moving up
any branch drains, toilet pans and PVC capped
inspection openings!
• When managing drain larger than 6’’, be sure to add
an extension to the Root Ranger in order to prevent
it from becoming wedged.

HOSE WEAR
Jetting hoses must be checked daily for wear and tear,
and immediately replaced if deemed to be damaged.
ROTHENBERGER supply strictly premium quality,
exible jetting hoses on all jetters.
Never be tempted to use a lower grade hose.
STAY SAFE.

SAFE JETTING
NOZZLES
There are 3 main types of penetrating nozzles; the
Predator, the Negotiator, and the Compressor.
Furthermore, these 3 nozzles come in different
conguration options; 3 rear 1 forward, 6 rear 1
forward, and 6 rear only.
The Predator is a great starting choice for
general purpose drain cleaning. It
comprises a long-pointed nose used for
penetrating deep into a choke and blasting out the
debris.
The Negotiator has been purposely
designed in a shorter manner in order
to move more effectively around tight bends and traps.
It is a nice multi-purpose nozzle for any drain cleaning
application.
The Compressor is smaller yet again,
and this nozzle is best used when
attacking smaller blockages. A new extension may also
be purchased for the Compressor.
The Root Ranger is used to clear
what the Penetrator nozzles leave
behind. It consists of 1 rear thrust
port and an optional front jet. This nozzle will
effectively clear almost anything from the drain and is
the primary root cutter used by plumbers throughout
the world.
• Do not hold any nozzle while pressurised.
• Do not allow any nozzle to leave the drain while
pressurised.
• Hoses must be conspicuously marked at a nominal
distance of 1 metre from the nozzle to indicate the
location of the nozzle.
• Always use a safety plate or safety shield in case
nozzle turns through 180° in the pipe and returns
back to the entry.
• The bend radius of the hose, coupling & nozzle
combined should be more than the internal diameter
of the pipe. If not, a starter bar (a length of rigid pipe)
should be tted to increase the bend radius as
necessary.
Root Ranger Turbo Nozzle
• Never use the Root Ranger nozzle in the drain with
a diameter that is larger than 150mm (6’’) without a
xed extension that equals the diameter of the pipe.
• The Root Ranger nozzle must be used in accordance
with your own safe work place environment
guidelines.
• Never allow an inexperienced operator to operate
this nozzle.
• Clean Root Ranger nozzle after every use and then
store in a safe place. Regularly remove the turbine
barrel in order to clear debris. Any debris that are
left in the barrel may damage the ceramic insert.
• Ensure the nozzle is not damaged and the jets are
not obstructed.
• Never become lackadaisical whilst operating the
Root Ranger nozzle! The jet of the Root Ranger has
the capacity to cause massive injuries to your esh
and organs. Additionally, ensure a fast shut down
procedure is ready and waiting whilst you are
operating this nozzle.
Please note that dropping the Root Ranger may
damage the ceramic insert.
NOZZLE SAFETY - RESPECT THE PRESSURE
NOZZLE WEAR
As drain cleaning nozzles or wash down nozzles have
worn, pressure loss will occur. Regular nozzle replace-
ment is imperative if you intend to maintain constant
and maximum efciency of your drain cleaning jetter.

OPERATOR’S HAND SIGNALS
This section offers a set of hand-signals, or non-verbal
communications, to be utilised when carrying out water
jetting operations.
•Pressurise System
Thumb pointing upwards with the
rest of the hand closed. Starting at
shoulder height, the arms move up
and down.
•Depressurise System
Formulate a st. Starting at
shoulder height, move the
arm back and forth.
•Raise Pressure
First nger pointing up with the
rest of the hand closed. Move the
hand in a circular motion.
•Lower Pressure
First nger pointing down with the
rest of the hand closed. Move the
hand in a circular motion.
Medical Recommendation
If an accident occurs in which pressurised water
penetrates, or appears to have penetrated the skin,
one must seek medical assistance immediately.
Immediate First Aid
In situations where medical examination is not
immediately possible, such as when an injury is
sustained in a remote location, appropriate rst aid
should be applied, and the patient observed closely
until medical treatment becomes available.
Medical Alert Card
All operators engaged in commercial and industrial
water blasting activities should carry an easily
accessible, waterproof medical alert card. This card
should:
• Outline the likely nature of particular injuries and
post-accident infections that may be caused by high
pressure water blasting;
• Provide details of the necessary rst-aid treatment
that must be applied immediately and maintained
until medical treatment may be arranged; and
• Provide the name(s) and phone numbers of medicos
that should be contacted in order to obtain expert
medical advice for the treatment of high-pressure
water blasting injuries.
Additionally, the card may:
• Identify the worker, and;
• Outline medical information concerning the worker,
such as one’s blood type, allergies, and other unique
conditions, such as asthma.
ACCIDENT REPORTING
•Reporting: All accidents or injuries, regardless of
whether they are deemed to be ‘lost time’ or ‘no lost
time’ injuries, must be recorded, thus adhering to
the recommendations detailed in AS 1885.1.
Additionally, incidents deemed to be ‘near misses’
must also be recorded in an effort to provide an
accurate record of signicant incidents that hold the
potential to lead to a serious injury in the workplace.
Consequently, appropriate measures may be
implemented to minimise or even eliminate these
potential hazards.
•Personal Injuries: In the event that a person is
injured as a result of the impact caused by a water jet,
the injury itself may appear insignicant and thus
provide little explanation as to the extent of the injury
sustained below the surface of the skin. While only
a small hole may be present, quantities of water may
have penetrated the skin, entering the esh, deeper
tissues and organs, causing serious injury.
15
For those that sustain equipment related injuries whilst
operating the system, immediate hospital attention
is critical. In such cases, it is imperative that medical
personnel be apprised of all facts relevant to the injury
at hand.

WARNINGS
OVER-SPEEDING & MOUNTING
•Over-Speeding : Do not operate the machine at over
pre-set engine speeds as this can cause serious pump
damage and will void the warranty.
•Frame Tie-Downs: Do not operate the machine while
the frame is secured by transit only tie-down points as
this may lead to frame damage.
• Machine should be mounted on a at surface or level
mounting points to prevent any stress to the frame.
• Machine should be installed in a manner that allows
access to the pump and engine for maintenance
purposes.
• Machine shall not be installed in an enclosed
environment.
HIGH-PRESSURE SETTING
•High Pressure Setting : The high-pressure pump is
specically factory set to operate at its rated
pressure. DO NOT ADJUST. Tampering with the
pressure regulator can be very DANGEROUS.
Consequently, it will void the warranty.
•CHECK NOZZLES & COUPLINGS WEEKLY, clean after
each use
Furthermore, if the pressure does begin to decline,
check the nozzle for expected wear. If you nd that
a nozzle is worn, it should be replaced immediately.
Using the machine with an incorrect nozzle size can
be very DANGEROUS to the operator and will void
the warranty.
JETTER DAILY CHECKLIST
1. Check pump oil level.
2. Check engine oil level.
3. Check nozzle for wear.
4. Check all high-pressure components for any leaks,
damage, wear or corrosion, such as the gun/lance,
