Blowing pull line into cable conduits (ø 25-200 mm)
Operating Manual EZ300 Version 05/2021 page 14 / 30
8. Blowing mode with EZ300
1. Conduit ends must be clean and cut off evenly
(if not possible
→
use orange cone)
2. Decide on the conduit end at higher level
3. Post control person on opposite side (where device is not in use).
(eye protection, wear safety goggles)
4. Fill the tank with the mixture of gasoline and engine oil
– see instructions
5. Adjust blowing connection (bayonet catch)
6. Fix head piece or special equipment appropriate to conduit Ø
7. Provide shuttle suitable for pipe inside diameter
TOLERANCE to inside Ø + 0 / -2 mm (see shuttle installation)
8. Start the engine according to the instructions
9. Apply foam ring close to conduit
10. First blow through the tube with air only (dirt, dust, water)
11. Check volume of air flowing out (be careful!)
12. Switch off the engine
13. Insert the pull line through the pull line supply and knot it tightly to the screw of the shuttle, with only
a short end left
14. Place the corresponding shuttle in conduit
15. Start the engine
16. Place the foam ring close to the conduit and blow in the pull line without interruption
17. Increase blowing speed by throttle lever, if necessary lock throttle lever
18. DO NOT block air intake/screen of the EZ300 with clothing or body
19. As soon as the shuttle has reached the end of the conduit, the pull line stops uncoiling
- if the shuttle pauses: pull back by hand and try from the opposite side or with alternative
accessories (see use of accessories eg. suction mode)
20. Store the device in a safe place and switch off the engine as instructed
21. Insert side: cut the line and secure it from retraction
22. Outlet side: release shuttle and secure line from retraction
Blowing mode completed: always remove head piece and blowing connection!
How to couple two pull lines rolls:
If the existing line length of one roll is not sufficient, you may add another line roll:
1. You are working with a started roll of pull line, make sure to secure the end of the line so that it
cannot slip into the duct (large knot / tie object)
2. Stop the blowing process on time before the end of the line
3. Release the knot / object and carefully pull the remaining line completely through the line supply
4. Thread the line start of the second roll through the line supply
5. Tie the end of the first roll firmly and strongly to the start of the second roll (for example, with a
Figure Eight (Flemish) knot)
6. Place the EZ100 tight to the duct and continue blowing
7. When working with a parachute make sure to keep pull line tense, to keep parachute open.
ATTENTION: connecting two roll ends automatically reduces the tensile strength
NEVER BLOW IN SHUTTLE WITHOUT PULL LINE
–
MAY GET STUCK OR LOST IN THE DUCT AND CAN’T GET PULLED BACK.
