3. Keep all guards and safety devices in place. Do not operate this equipment with guards
removed or damaged.
4. Keep hands, feet and loose clothing away from moving parts, especially at cable entry
points.
5. Always stop the machine and isolate compressed air and electrical services to carry out
lubrication and servicing.
6. Check machine before starting for worn or damaged parts. Check for signs of loose nuts
and bolts etc.
7. If machine is left unattended, insure that unauthorized use is prevented.
8. Never leave the machine unattended while in use.
9. Consider the use of safety barriers, especially when used in public places, observe all
statutory requirements for working environments.
10. Beware of pinch points involved with rotating components.
11. Beware of hot surfaces, machine uses compressed air.
12. When operating machine always wear appropriate safety clothing, hearing protection, eye
protection, hard hat, safety shoes and leather gloves, machine operates with compressed
air at up to 220 psi.
13. Prior to installation insure the tube route is connected properly.

16. No personnel are to be in manholes or ducts when the Cable Blowing Machine is being
operated.
17. The machine must be operated on firm ground.
18. Stay clear of cables or lines under tension.
19. Stay clear of pressurized air line and tube.
20. Only use the machine for its intended purpose. Do not use the roller drive without the air
chamber to push or to retrieve cable or blow air in the far end of tube to help cable
recovery.
21. Do not place cable drum too close to the Cable Blowing Machine.
22. Do not tamper with pressure relief valves or pressure reducing valves.
23. Ensure the cable drum rotates freely on its stand, the cable should leave from the top of
the drum.
24. The cable should enter the machine in a clean and dry condition. In damp, dusty atmos-
pheres, the cable should be cleaned continuously as it enters the machine.
FAILURE TO DO SO MAY RESULT IN PERSONAL INJURY, AS THE CABLE
COULD BE EJECTED FROM THE CABLE BLOWING MACHINE WITH HIGH
FORCE AND VELOCITY.

Tube connecting fittings are suitable for operating at 220 PSI air pressure.
Tube clamp securely tightened.
Compressor capacity 220 PSI and suitable for size of tube being used.
Cable drum must be located directly behind and in line with the blowing machine.
Air chamber, drive rollers, cable guides, must be clean and free from debris, sludge, dirt,
water and lubricant.
The cable must be hand guided into the blowing machine through a dry clean cloth by the
operator wearing work gloves.
Ensure the compressed air supply is not applied to the cable until required amount of ca-
ble has been installed.

3. GENERAL DESCRIPTION
The GMP Whisper Micro Cable Blowing Machine is
designed to install micro fiber cable into micro tubes.
The Whisper uses a user supplied variable speed drill
to drive a compliant roller.
The shaft is covered with a rubber roller to prevent
damage to the cable. The roller may be changed
quickly using one simple tool.
The pressure the rollers apply to the cable is adjusta-
ble.
A full range of accessories is available to allow the
machine to handle a wide range of cables and micro
tubes.
The Whisper may be placed on a stand or on the optional tripod kit to bring the cable to a suitable height. The Whisper is supplied with a reinforced soft case which will protect the ma-
chine from damage during transit and storage.
