Signode PRHM-34 - Troubleshooting: Sealing, Cut-off, and Joint Strength Issues

35
#3 SYMPTOM: SEALING AND CUT-OFF IS INCOMPLETE
CAUSE REMEDY
1. Improper seals being used.
2. Incorrect tool operation pressure or
tension regulator set too low.
3. Worn or broken sealer mechanism.
4. Worn or broken diaphragm (17).
1. Check that the proper Signode seals
are being used (See page 4 of this
manual).
2. A minimum of 70 psig (4.8 bar) is
required to complete the sealing and
cut off cycle. See the illustration on
page 3 for the appearance of a
properly notched seal.
3. Check jaws (47), side plates (53, 56),
notcher (48), cutter (57), or leading
edge of tensioner foot (83). They
should be reasonably sharp. Replace
as required.
4. Check diaphragm (17) for holes or
tears. Replace if damaged.
#4 SYMPTOM: LOWER STRAP SLIPPING THROUGH SEAL
CAUSE REMEDY
1. Improper seals being used.
2. Incorrect tool operating pressure or
tension regulator set too high.
3. Strap tail is too short.
1. Check that the proper Signode seals
are being used (See page 4 of this
manual).
2. Decrease tension by adjusting
regulator of air motor.
3. Increase length of tail strap under
seal.
#5 SYMPTOM: LOW JOINT STRENGTH
CAUSE REMEDY
1. Improper seals being used.
2. Worn or broken sealer mechanism.
1. Check that the proper Signode seals
are being used (See page 4 of this
manual).
2. Replace worn or broken jaws,
notchers, side plates or pins.
