I. SPECIFICATIONS
II. CAN OPENER DESCRIPTION
The Model 270 electric can opener, manufactured by the Edlund Company, is approved by
the appropriate certifying organizations. The model 270 can opener is a table-type opener
with a sculpted base to guide a full No. 10 can. All the external parts are manufactured of
stainless steel and other non-corrosive materials. The knifeholder, knife, drive gear and shield
can be removed easily without tools for replacement or cleaning.
The Model 270 operates at two speeds. The high speed is used for most can opening
operations. The low speed is intended for difficult to open cans. The operating speed can
be selected by positioning the rocker switch on the side of the opener to the speed desired.
III. CAN OPENER OPERATION
To operate, plug the power cord into a grounded outlet with the same voltage as listed on
the back of the can opener. If opening a standard seven-inch high no. 10 can, slide the can
against the can opener sculpted front and drive gear. and pull the handle forward to its
locked-down position. Remove your hand from the can when the can opener starts turning
the can. The motor will start and the can will rotate until the lid is severed from the can,
after one full revolution. Raise the actuating lever to stop the opener.
If the lid is not completely severed or if the can is ejected from the gear, consult the
maintenance instruction and/or trouble-shooting guide later in this manual. After opening
the can, raise the lever and grasp the can simultaneously
CAUTION: SEVERED CAN LIDS HAVE SHARP EDGES. USE OF A PROTECTIVE
GLOVE OR TONGS IS ADVISED WHEN HANDLING LIDS.

IV. CLEANING AND MAINTENANCE INSTRUCTIONS
WARNING: NEVER CLEAN OR MAINTAIN ANY CAN OPENER WITHOUT
UNPLUGGING THE UNIT FROM ELECTRICAL POWER SOURCE.
THE CAN OPENER MUST BE KEPT CLEAN.
The Model 270 can opener must be kept clean, not only for the obvious reasons of
sanitation, but more important, for operational reasons as well. The rotary knife of an
electric can opener must rotate freely for the can opener to operate properly. If the knife is
bound by residual food product, the knife will not rotate and wear will not be distributed
around the periphery of the knife.
MORE IMPORTANT THAN THE WEAR, A NON-ROTATING KNIFE
WILL NO LONGER BE SHEARING THE METAL CAN TOP AS
DESIGNED AND METAL SLIVERS MAY OCCUR!
The knifeholder, knife, gear and shield can be removed as follows in order to clean
and maintain the Model 270 can opener.
Removal of the knifeholder, knife, gear and shield.
1. To remove the above parts, first rotate the knifeholder latch clockwise.
2. Slide the knifeholder to the right (Fig.1)
3. Rotate the knifeholder counterclockwise and then pull it off to the right. Knifeholder is now
free. (Fig.2)
4. To remove the knife, grasp it by the shoulder, twist it and pull it off (Fig.3)
5. To remove the gear and the shield, rotate the shield 1/4 turn clockwise. (Fig.4)
6. The shield and the gear can now be removed. (Fig.5)

CAUTION: MAKE SURE THAT THE KNIFEHOLDER IS LATCHED AND THE GEAR
IS PROPERLY LOCKED IN PLACE BEFORE OPERATING THE CAN OPENER.
DO NOT OPERATE THE CAN OPENER WITHOUT INSERTING A CAN.
1. The knife should be removed often so that the knife, knife stud and knife holder can be properly
cleaned. Remove the knife holder, which contains the knife stud and knife according to the above
instructions and clean the knife, knife stud and knife holder. After these parts are clean, the knife
stud, which is part of the knife holder, should be examined to make sure that the rubber "O" ring on
the knife stud is in place and in good condition. To greatly reduce the chances of the knife sticking,
the knife and knife stud should be lubricated with vegetable oil. Replace the knife so that the larger
diameter of the knife is toward the front boss of the knife stud. BE SURE THAT THE KNIFE
ROTATES EASILY AFTER IT IS ASSEMBLED ON THE KNIFE STUD.
BEFORE EACH USE, INSPECT THE EDGE OF THE CAN OPENER KNIFE FOR NICKS
OR SIGNS OF WEAR.
2. The factory-made edge of the can opener knife is designed to separate the metal can lid. It will
not function properly if allowed to become dull or nicked. If through wear a knife becomes
excessively dull, it will be difficult to pierce the can and the knife will no longer separate the lid
completely at the end of the cut. Replace the knife when it becomes excessively dull or if nicks
occur on the cutting edge.
WARNING: NEVER TRY TO SHARPEN A CAN OPENER KNIFE. IF THE KNIFE
EDGE IS MADE TRULY SHARP, IT CAN SHAVE OFF SLIVERS.
3. The teeth of the drive gear must be clean and sharp. Remove and clean the teeth of the drive
gear after each use to remove the build-up of food residues. If the drive gear starts to slip on the
bead of the can, its teeth may be worn. Replace the gear by using the previous disassembly and
assembly instructions.
4. The can opener housing and other external parts are made of stainless steel and can be easily
cleaned using a damp cloth.
WARNING: NEVER CLEAN ANY PART OF THE OPENER WITHOUT UNPLUGGING
FROM THE ELECTRICAL POWER SOURCE. NEVER SUBMERGE OR PLACE CAN
OPENER IN WATER.
5. If for any reason the can opener does not function properly, consult the Troubleshooting Guide
for assistance or contact an authorized service agent.
