Select Best Path for Projectile
If more than one path is available, cap one of the paths.

Multi-path Hose
When cleaning a hose or tube configuration with multiple paths, as shown in Illustration 7, clean the closest path to the projectile starting point first. All openings down stream must be capped to allow only one path for the projectile to follow. For example, plug all hoses to the right of path #1 for proper projectile direction and cleaning. Next, plug 1 and 3 for path 2 cleaning, and finally plug 1 and 2 for path 3 cleaning.Operating Procedure
Before operating the hose cleaner group, check to make sure all the necessary safety precautions have been taken and always observe all safety instructions.Note: A clean gun, clean nozzles, and clean (not degraded) projectiles must be used. Degraded projectiles can leave behind particles in the hoses.
Select the proper nozzle and projectile for the hose to be cleaned. Refer to Tool Operating Manual, NEHS0643.

Latching Faceplate
Close the faceplate and make sure the safety bar and release mechanism locks the faceplate into position. Refer to Illustration 8.
Illustration 9 g01244656
Projectile Catcher
Make sure that the exit end of the hose is correctly contained in the projectile catcher (or catcher bag) and the catcher is secure. Refer to Illustration 9.
A 130-6422 Job Bag should be used while cleaning smaller hose assemblies in the field. Since some of these assemblies will be disconnected, but not removed from machinery, the usage of 130-6422 Job Bag is recommended.Note: Recover the used projectile so the projectile can be analyzed to determine the condition and cleanliness of the hose.

Firing Projectile
Place the nozzle firmly against the hose, making a firm seal. Obtain an airtight seal. In the event of a nozzle does not fit correctly, try reducing the nozzle size. Refer to Illustration 10.
Depress the trigger, making sure that the trigger remains depressed until the projectile emerges from the other end of the hose. If the trigger is released prior to the projectile emerging, the projectile will remain in the hose until the trigger is pressed again.
Based on cleaning level desired, repeat the procedure (with a new projectile) from the opposite end of the hose.Projectile Storage and Disposal
New projectiles should be stored in covered boxes or contaminant free cabinets to reduce exposure to direct sunlight or florescent light.Note: Exposure to direct sunlight or florescent light will cause discoloration and deterioration of the projectiles over time. Leave projectiles in protective shipping bags.Do not reuse projectiles. Projectiles are discarded after one use only. Used projectiles must be disposed of properly.Troubleshooting

Troubleshooting
Problem Solution
Projectile remains lodged in the hose tube, pipe, or assembly To clear a projectile, operate the projectile launcher from the other end of the pipe or hose without using a projectile.
Check hose, tube, or pipe for leaks, holes, or breakages.
Check for line restriction in tube or hose. For example, inside diameter going from 10 mm (0.4 inch.)
Check projectiles for tear marks.
Check air pressure setting of the air source.
Check condition of hose and fittings from
