Assembling the cutting ball
The cutting ball is screwed onto the high-pressure hose on
the vehicle. The thread size depends on the size of the
cutting ball and can be found in the section “Technical
Data” on page 10.
Normally, the nozzle has a counterclockwise thread, while
the connecting thread rotates clockwise. This prevents the
nozzle from detaching itself from the connecting thread
during operation.
Setting up the work area
Prior to working with the cutting ball, the following actions
must be taken:
•Set up barriers and safety equipment (warning triangle,
block off the area, etc.)
•The necessary information on the wastewater flowing
through the shaft must be obtained (chemicals, gas,
vapors, etc.)
•Measuring instruments such as explosive gas meters,
oxygen meters, gas warning devices, etc. must be
readily available.
•The work area must be blocked off and secured so that
there is no risk of falling or other traffic-related
dangers.
•Make sure that the appropriate nozzle sizes are
available for cleaning the pipes. The application range
of each nozzle is listed in the "Technical Data" section
on page 10.
•The layout of the pipes must be known and the
respective blueprints must be available before
starting the work. Support personal must be on hand
to monitor potential discharge openings in the pipe.
•Have the liability waiver signed to protect against any
possible damages.

DANGER
Risk of falling!
WARNING
Trip hazard!
WARNING
Toxic substances, do not inhale!
CAUTION
Risk of property damage!
Never let the cutting ball skip (e.g., pulling the
hose back and suddenly letting go)! This may
damage the ball and the pipe.
Pay attention to the warning signs that inform
you of the necessary personal protective
equipment to be worn!

June 4, 2020 ©2020 enz® technik ag 13
Operating the cutting ball
•Push the entire length of the tool into the pipe to be
cleaned.
•Slowly increase the pressure to 100 bar at the end of
the nozzle. This pressure is enough to clean a pipe
effectively.
•Measure the length of the pipe to be cleaned (mark it
on the hose) and check the mark constantly during the
cleaning process.
•In difficult terrain or when working over large
distances, support personnel must monitor the exit
shaft.
•Pull the tool back at regular intervals to avoid
blockages
Cleaning pipes with minor damages
Slightly damaged pipes will usually exhibit cracks in the
pipe's wall. If detected, please contact the respective
department or authorities.
When working inside a slightly damaged pipe, extreme
caution must be used. When flushing the cracks, pipe
fragments can break off and the surrounding area may be
flushed out.
Use extreme caution when cleaning and, if in doubt, stop
using the tool.
Completing the work process
If possible, use a special sewer pipe video camera to inspect
the cleaned pipes. Pay special attention to ensure that
exiting fluids do not drain into environmentally-sensitive
areas.
After completing the pipe cleaning process, reseal all shafts.

Adding Vibration
CB
In case of hard deposits, you can add more vibration.
Stage 1
Loosen the locking screw and remove the eccentric weight.
Screw the locking screw back into the cutting ball.
Stage 2 (CB90)
Remove the locking screw and the eccentric weight. You
should now be able to cut away hard deposits.
After use, put the eccentric weight and the lock screw back
in place. This will prevent parts from getting lost.

Maintenance
Replacing nozzle inserts
The nozzle inserts must be inspected during regular
intervals (once a month). The wear and tear of the nozzle
depends on the degree of contamination of the used water.
If recycled water is being used, the nozzle inserts must be
inspected daily.
CAUTION
Worn nozzle inserts impair the efficiency of the
cleaning process.
Damaged nozzle inserts may only be replaced by
identical nozzle inserts with the same diameter.
If you do not know the nozzle diameter, JetCalc
must be used to determine it. If the tool is not
correctly assembled, it may become damaged..
•Coat the nozzle insert threads and the inner threads of
the nozzle with Loctite No. 243 adhesive. Both threads
must be cleaned before applying the adhesive!
•Immediately screw the nozzle inserts into the tool body
up to the mechanical stop, then use a socket wrench to
slightly tighten each insert.
Care
After long periods of non-use, spray the nozzle
holes and the connecting threads with OIL
SPRAY BIO (item no. C191).
Disposal, environmental protection
Do not use excessive amounts of water. This will help
preserve our natural resources.
The tools do not require any special disposal procedure.
Simply dispose of them with other scrap metal.
Please note that pipes are only cleaned if the composition
of the wastewater is known (in particular industrial
wastewater). Under no circumstances may chemicals or
other toxic substances flow through defective pipes and
enter environmentally-sensitive watersheds or other areas.
Defective pipes or leaking substances must be reported to
the supervisor.
