1. General Information
The V2 is a unique device designed for the installation of fiber optic cables directly into ducts. The
V2 consists of a duct clamp and a belt drive system, which, when combined, installs a cable into an
airtight duct at speeds ranging from 0-200 m/min.
The V2 comes equipped with an LCD display as standard. The machine should be complemented with
specified duct clamps, cable seals, and cable guides depending on the dimensions of the duct and
cable for installation.
This user manual provides a comprehensive description of the V2, designed to feed fiber optic cable
through ducts. The duct must have been previously installed underground or above ground to receive
the fiber optic cable and must be suciently long at the outlet to be received by the machine. The
duct must be made of material with adequate pressure resistance to be tightly sealed in the machine’s
duct clamps. The duct should be airtight up to a pressure of 16 bar. Duct sizes range from 7 mm-50
mm, while fiber optic cables range from 2.4 mm-16 mm.
The V2 consists of a duct clamp manufactured in two halves that clamp around the duct. The duct
clamp holds a seal through which the fiber optic cable is fed before entering the duct. The duct
clamp and cable seals can be replaced to accommodate dierent duct and cable sizes. The duct is
mechanically clamped between the clamps, preventing movement in all directions. Seals fit around the
duct when clamped securely.
The fiber optic cable is fed through the duct with a combined pulling/pushing force. The pulling force
is achieved when pressurized air is fed into the duct clamp and forced into the duct, generating
resistance on the fiber cable from the airflow passing over it. The pushing force is created by engaging
the belt drive system. As the belt drive system feeds the fiber cable into the duct, pulling force is
generated by the airflow. The fiber optic cable floats inside the duct, minimizing resistance to being
pushed in by the belt drive.
The use of the V2 for operations other than those described in this manual is considered hazardous
and is discouraged. The manufacturer is relieved of any responsibility, civil or criminal, for the use of this
machine for purposes other than intended. The manufacturer’s responsibility ceases, and the warranty
becomes void when any of the following occur:
A. When the V2 is used for purposes other than described in this manual.
B. Modifications and/or alterations are made without written approval from the manufacturer.
C. Non-use of original manufacturer parts.
D. Poor maintenance.
E. Failure to use provided safety devices or equipment.
F. Connection of this device to machines and/or parts that have not been manufactured or
approved in writing by the manufacturer.
G. The V2 should not be used to install any cable other than fiber optic cable specified within the
range outlined in this user manual.
H. The V2 must not operate without oil in the oil reservoir, immediately voiding the warranty.
I. Check the oil level in the reservoir daily.
Jetting AB is not responsible for damages resulting from improper use of the V2.

Always use clean, oil-free, and dry air.
Route all hoses in a safety way to prevent tripping hazards.
To avoid creating tripping hazards, Place the air hose away from the work
area and secure it to a stable object.

6. Cable Crash Test
Cable crash testing is a rapid and simple step that should be completed before attempting to install
fiber cable with the V2. This test is necessary to set the regulator’s position for the motors under the
breakpoint (pressure force) where the V2 can cause fiber cable damage due to over-pressurization or
encountering an obstacle in the duct system. Each fiber cable has dierent pressure values based on size
and design.
IMPORTANT
Use the same size of cable and duct that will be used for the job.
Jetting cannot be responsible for any cable damage.
Crash Test: For all cable types > 3 mm diameter
Set the pressure between the belt drives and fiber cable at the lowest possible setting that allows a
desirable installation speed.
1. Insert the fiber cable and seal into the duct as it would be for the actual installation.
2. Install a 2-3 m test length of duct in the V2 clamp and secure the clamp.
3. Block the end of the test length of duct.
4. Tighten the belt drives against the fiber cable with the belt drive engaged in the forward direction until
the fiber begins to be installed.
5. Insert the fiber cable into the blocked end of the duct.
6. Belt drive slippage should occur on the fiber before the fiber bends.
7. Tighten the belt drives against the fiber cable half a turn.
8. Repeat steps 6-7 until the fiber cable bends. This is your pressure force slip limit.
9. Loosen the belt drives on the fiber cable a quarter turn and perform the test again to confirm that no
bending has occurred. MAINTAIN THIS SETTING FOR THE FIBER CABLE FOR ACTUAL INSTALLATION!
10. Replace the test length of duct with the actual installation duct and proceed to section 7. Machine
Operation of V2.
13
Always wear protective equipment: a safety helmet,
safety glasses, steel-reinforced safety shoes, and
work gloves.

7.3. Activate Air Pressure
Slowly open the ball valve to allow airflow to the duct clamp. Do not apply maximum air pressure and
flow on the initial air insertion. Do not open the air supply until the desired speed slows down (about
100 m). Then gradually increase the air pressure in steps of about 10-20% at a time. Follow the speed of
the cable installation and balance air pressure gently against belt drive speed. Too much air can slow
down or stop the installation.
7.4. Adjust Speed
Use the regulator to adjust the belt drive speed in combination with the Easy Joystick Controller to ensure
smooth installation and match the amount of air pressure used so that the forces cooperate.
7.5. Install Cable
The cable must be dry and clean of dirt.
7.6. Stop Belt Drive
To stop the belt drive, reduce the air pressure on the regulator or move the Easy Joystick Controller to the
STOP position. The emergency stop is activated by turning it clockwise.
14
Do not exceed 16 bars when using the device. Compressed
air generates flying debris. Always wear personal protective
equipment.
7. Machine Operation
7.1. Verify Adjustable Pressure Force
Verify that the adjustable pressure force is set to the established crash test value, and the speed is at a
minimum. Turn the regulator to 0 bar by lifting and rotating the ring fully counterclockwise. Ensure that
the Easy Joystick Controller is in the STOP position.
7.2. Connect Belt Drive
The belt drive can be maneuvered forward and backward with the Easy Joystick Controller. For instal-
lation, connect the belt drives by first increasing the regulator to the desired air pressure for the motors,
e.g., 1-6 bars. For forward drive, move the Easy Joystick Controller to the forward position. This operates
continuously and also controls the speed. Install the cable in the duct with motor power only until the
speed starts to slow down (about 100 m). Then, compressed air is added.

7.7. Check Oil Level
Check the pneumatic oil container to ensure continuous oil mist lubrication to the motors.
The oil level must always be above the hose in the oil container.
Max
Min
7.8. Refill Oil
