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 finger 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 muffler 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 influence 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 traffic and non-essential personnel
clear and safe.
4. Check for flammable 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.
