When a Model 270 electric can opener is returned to the factory for warranty repair, repair or for any
other service issues, the following procedure will be used:
1.
Read the Quality Improvement Report that accompanies the product to determine what problems
or complaints that the customer has listed.
2.
Perform a ground continuity test and a dielectric withstand test according to the Final Inspection
Procedure EC1062.
A. If the unit passes both tests, proceed to step #3.
B. If the unit fails the ground continuity test, proceed to step #7.
C. If the unit passes the ground continuity test but fails the dielectric withstand test, proceed to
step #8.
3.
If the unit passes both the ground continuity and the dielectric withstand test, it is safe to operate.
Plug the cord set into a receptacle with the same voltage as listed on the rating label and check to
be sure the motor runs when the actuating lever is actuated.
4.
A. If the customer has not listed any problems or complaints, proceed to step #6.
B. If the customer has listed any problems or complaints in the Quality Improvement Report, check
to see if these complaints can be duplicated.
5.
If the can opener functions as the customer has described, proceed to the
Troubleshooting Guide to find the cause or causes of the problem and correct according to the
correction procedure listed in the Trouble Shooting Guide and then perform the Final Inspection
Procedure EC1062.
6.
If the can opener does not function as the customer has described or if the customer has not listed
any problems or has not fully described the problem, open a few cans to determine just how the
can opener is functioning. Check the front to back clearance between the back of the knife and the
front of the gear. When the actuating lever is in the down position to make sure it is 0.017 – 0.022
wide. Check the up and down clearance between the top of the drive gear and the bottom of the
knife holder with the knife removed and the actuating lever in the down position to be sure it is
between .102 - .107 inch. Check the on position of the motor to be sure the motor comes on just
as the knife starts down over the top of the drive gear teeth and that the motor starts before the
knife pierces the can.
If the can opener is not functioning properly, proceed to the Trouble Shooting Guide and find the
cause or causes of this problem. Correct the problem using the correction procedure listed and
perform the Final Inspection Procedure EC1062.
7.
If the unit has failed the ground continuity test proceed to the Trouble Shooting Guide, find the
cause of the problem and correct according to the correction procedure. After the problem has
been corrected, proceed to step #2 to perform the ground continuity and the dielectric withstand
test to make sure that the unit is safe to operate before doing any repair.
8.
If the can opener passes the ground continuity test, but fails the dielectric withstand test, consult
the Trouble Shooting Guide and correct the problem using the correction procedure listed.
9.
If the actuating lever and cam assembly are removed for any reason, remove the
frame assembly and check the motor endplay and the length of the motor brushes. If the endplay
exceeds 0.035 inches, shim the motor to reduce the end-
play to 0.030 inches maximum. Replace the brushes and brush springs as needed.
