Troubleshooting Guide
(arranged in sequence of machine operation)
Possible Cause
1. Valve V-4 out of adjustment or
defective.
2. Flow control closed.
3. Power valve P-2 defective.
1. Valve V-3 out of adjustment or
defective.
2. Valve V-2 out of adjustment or
defective, sticks closed when box
paddle is actuated.
1. Valve V-6 out of adjustment or
defective.
2. Valve V-5 out of adjustment or
defective.
3. Power valve P-2 defective.
4. Valve V-7 out of adjustment or
defective.
1. Valve V-7 out of adjustment or
defective.
2. Valve V-5 out of adjustment or
defective.
3. Check for loose cylinder rod
connection.
1. Dull blade.
2. Blade out of adjustment.
1. Bad jaw roller.
2. Valve V-6 actuates before tape is in
jaw assembly.
3. Valve V-7 actuated before tape is
clamped.
4. Wave washer (Item #81) missing from
tape holding roller (Item #27).
5. Jaws close too slow.
6. Feed cylinder extends too fast.
7. Low clamping force on tape. Missing
or broken jaw spring (Item #114).
8. Bad one-way roller assembly. End of
tape is not fed into the jaw assembly.
Problem
Cut-off assembly and buffing assembly
cycle extend and retract and unit stops.
Buffing arm/cut-off blade out of sequence,
oscillate back and forth.
Feed assembly retracts and stops.
Feed cylinder extends but does not
actuate V-8 valve.
Tape not cutting or tape end shredding or
buffing rollers stop in mid-stroke and do
not apply the tape.
Tape not being held by jaw assembly.
Correction
1. Adjust or replace valve V-4.
2. Adjust extend flow control for feed
cylinder.
3. Replace valve.
1. Turn off air supply adjust valve V-3.
Retract cut and buffing cylinder to
retracted positions. Actuate and hold
V-3 as air is turned on. This should put
air circuitry in sequence.
2. Adjust or replace valve V-2.
1. Adjust or replace valve V-6.
2. Adjust or replace valve V-5.
3. Replace valve.
4. Adjust or replace valve V-7.
1. Adjust or replace valve V-7.
2. Adjust or replace valve V-5.
3. Retighten and adjust V-8 valve if
needed.
1. Replace blade.
2. Readjust blade and tighten screw.
1. Replace roller.
2. Adjust V-6 valve.
3. Adjust or replace V-7 valve.
4. Replace wave washer.
5. Adjust jaw cylinder flow control.
6. Adjust flow control for extending feed
cylinder.
7. Replace jaw spring.
8. Replace one-way roller assembly
located on feed assembly.
•
To reduce the risk associated with sharp blade hazards:
−
Keep hands and fingers away from tape cutoff blades under orange blade guards. The blades are extremely
sharp
•
To reduce the risk associated with mechanical and pneumatic hazards:
−
Allow only properly trained and qualified personnel to operate and/or service this equipment
•
To reduce the risk associated with pinch and entanglement hazards:
−
Turn air supply off and disconnect before performing any adjustments, maintenance or servicing the machine
