1. General information
The MJet V2 is a unique device for installing cable optic cable directly into duct. The MJet V2 is comprised
of an air block and a belt drive that, when combined installs a cable into an airtight duct, run at speeds
of 0 to 0-200m/min.
The MJet V2 greatly reduces pulling stress on the cable. The adjustable clamping force (push force) of the
belts will (stall the motor or) slip if the cable hits an obstruction.
The MJet V2 comes standard with a Digital LCD meter display, lube, oil and a service kit in a wooden
case.
These operating instructions contain a full description of the MJet V2, which have been designed for the
purpose of feeding cable through duct of uniform cross section. The duct must have previously been
installed underground or overhead to receive the optic cable and must be of sufficient length on exit to
be received by the machine. The duct must be of material with sufficient compression strength for it to
be adequately sealed in the duct clamps of the machine. The duct must be airtight up to a pressure of
16bar. Duct(s) sizes range from 7 mm-50 mm, while cable optic cable(s) range from 2,4 mm-16 mm.
The MJet V2 consists of an air block that is made in two halves that clamp together around the duct/pipe.
The duct/pipe clamps hold a seal that the optical cable is fed through before entering the duct/pipe. The
duct/pipe clamps and cable seals can be interchanged to accommodate different duct/pipe and
cable sizes. The duct/pipe is mechanically clamped between the duct clamps at the exit of the air block,
preventing movement in any direction. Seals conform around the duct when clamped.
The optic cable is fed through the duct by a combined pulling/pushing force. The pulling force is achieved
when pressurized air is fed into the air block and forced into the duct, generating drag on the cable
from airflow passing over it. The pushing force is created by engaging the belt drive system. As the belt
drive feeds cable into the duct, drag force is created by the airflow. The optic cable floats in the duct,
minimizing any resistance to being pushed in by the belt drive.
The use of the MJet V2 for operations other than those described in this manual are considered
dangerous and are discouraged. Use of this machine for work other then what is intended, relieves the
manufacturer from any responsibility, civil or penal. The manufacturer's responsibility ceases, and the
warranty is voided when one of the following occurs:
A.
When MJet V2 is used for purposes other than what is detailed in this manual.
B.
Tampering and/or modifications carried out without written approval of the manufacturer.
C.
Not using original manufactured replacement parts.
D.
Poor maintenance.
E.
Not using supplied safety devices or equipment.
F.
Connection of this unit to machines and/or parts not produced or authorized in writing by the
manufacturer.
G.
The MJet V2 should not be used to install any cable other than cable optic cable specified within
the range outlined in this instruction manual.
H.
The MJet V2 should not be run without oil in the oil mist canister, this will immediately void the
warranty.
Jetting is not responsible for injuries incurred as a result of improper use of the MJet V2.
