3.0 CRITICAL POINTS THAT DRAMATICALLY AFFECT THE
OPERATION OF THE CABLE BLOWING MACHINE
Below is a list of point what dramatically affect the operation of the cable blowing machine:
1.
Pressure on the cable (position of the close arm assembly) should be set as per the instructions.
2.
Belts to be closed at all times when cable is installed into machine.
3.
Cord seals in air chamber in good condition and correctly fitted to provide good sealing.
4.
Correct cable and duct seal fitted.
5.
Duct fully connected and pressure tested.
6.
Duct and connecting fittings are suitable for operating at 15 Bar air pressure.
7.
Duct clamp securely tightened.
8.
Compressor capacity 15 Bar and suitable for the size of duct being used.
9.
Cable drum must be location directly behind and in line with the cable blowing machine.
10.
Air chamber, drive belts, pulleys and cable guides must be clean and free from debris, sludge, dirt,
water and lubricant.
11.
The cable must be hand guided into the cable blowing machine through a dry clean cloth by the opera-
tor wearing suitable work gloves.
12.
Ensure the compressed air supply is not applied to the cable until approximately 150 feet of cable has
been installed or the motor begins to labor.
DISCLAIMER
General Machine Products takes care in the design of its products to help ensure that the cable is
protected during installation. Due to the variety and different methods of cable manufacture the
responsibility of checking the cable compatibility with the equipment lies with the operator.
Therefore, GMP cannot accept liability for any damage to the cable.
2.2 GENERAL PNEUMATIC SAFETY INSTRUCTIONS
The GMP Jetstream Cable Blowing Machine is a pneumatic device, using pressurized air to project cable
at high velocities. Please observe the following precautions when operating the Cable Blowing Machine:
-
Compressed air can cause flying debris. This could cause personal injury. Always wear personal
protective equipment.
Ensure no personnel are in the manhole at the far end of the cable run. Severe personal injury may result.
Never open the air chamber when pressurized.
Only AUTHORIZED, fully trained personnel should operate the air compressor.
2.3 GENERAL ELECTRICAL SAFETY INSTRUCTIONS
The machine has electronic and electrical power and control circuits. Electric shock hazards exist that
could result in severe personal injury. Observe the following precautions to avoid electrical hazards:
Do not operate in water. Do not expose the machine to rain.
Do not remove cover of electronic control panel or power supply unit. There are no user serviceable parts
inside. Refer servicing to qualified service personnel.
