MAINTENANCE
WARNING
ALWAYS UNPLUG THE SLICER BEFORE PERFORMING ANY TYPE
OF MAINTENANCE TASK.
REMOVING BLADE FRAMES
Remove the top guard and front guard by removing the twelve slotted head screws
which hold them in place. See the illustration on the next page.
In addition to the above, the infeed table must be removed to allow removal of the
lower blade frame. This can be done by removing the two slotted head screws
securing it and pulling the table down out of the clips and out through the infeed
opening. See the illustration on the next page.
NOTE
Removal of the lower blade frame is not required to change its blades.
Pull the clip from the eccentric pin and slide the link toward the eccentric pin mounting
plate. See the illustration below.

REMOVING BLADE FRAMES (Continued)
WARNING
BLADES ARE EXTREMELY SHARP. ALWAYS HANDLE BLADE
FRAMES WITH CARE
Carefully lift the upper blade frame from the slicer. See the next illustration.
NOTE
Removal of the lower blade frame is not required to change its blades.
Remove the lower blade frame by first removing the capscrews. Do this with the cradle
in its normal top position, then remove the clip and link, and lift the blade frame from
the slicer in a manner similar to the upper frame removal.

MODEL 711 COUNTER TOP SLICER
0711S20005-4
REPLACING BLADE FRAMES
To replace the blade frames, reverse the removal procedures. ensure that the feet of
the blade frames rest snugly on the swing shafts. Tighten capscrews at the feet
securely with a wrench. Top links must be attached to the blade frames with clips back
in position.
CHANGING THE BLADES
WARNING
BLADES ARE EXTREMELY SHARP. ALWAYS HANDLE WITH CARE.
NOTE
When replacing all the blades, always remove the center blades first and
work towards the ends. Remove and install one blade at a time, NEVER
remove all the blades at once and then attempt to replace them all at once.
Place the upper blade frame on a flat surface. Insert the special knife tool into the
blade frame. See the illustration below. Lifting up on the knife tool will deflect the
upper blade mount, reducing tension on the cutting knife. Carefully remove the cutting
knife from the blade mount.

MODEL 711 COUNTER TOP SLICER
0711S20005-5
CHANGING THE BLADES (Continued)
The blades can be removed from the lower blade frame while it is still in the machine.
This is done by using a second special blade changing tool. Insert the tool into the
blade frame. Push the handle, toward the feet of the blade frame, deflecting the upper
blade mount reducing the tension on the cutting knife, allowing its careful removal. See
below.
Reverse the procedure to install replacement blades. A paper clip can be used to hold
the blade in position on a lower blade mount during blade installation. See the
illustration below.
CAUTION
NEVER PUT THE BLADE FRAMES IN A SLICER WITHOUT BLADES.

TIGHTENING THE BELT
CAUTION
OVER-TIGHTENING THE DRIVE BELT MAY CAUSE BEARING OR
MOTOR FAILURE.
Remove the top guard and rear inspection plate from the slicer. See the next
illustration. Locate the four motor mounting nuts and loosen slightly using a wrench.
CAUTION
DO NOT REMOVE THE MOTOR NUTS COMPLETELY.
Manually lift the motor upward to tighten the belt using care to keep the centerline of
the motor perpendicular to the centerline of the belt. The belt can be loosened by
carefully moving the motor downward. The drive belt should be just tight enough, using
moderate finger pressure, to allow a 3/8” deflection halfway between the motor drive
pulley and the driven pulley. When desired belt tension is achieved, re-tighten the
motor mounting bolts securely and replace the top guard and rear inspection plate.

MODEL 711 COUNTER TOP SLICER
0711S20005-7
REPLACING THE BELT
Remove the top guard and rear inspection plate from the slicer, as described under
“Tightening the Belt”. Loosen the motor mounting bolt nuts slightly (see Belt Tightening
section), and lower the motor as far as it will go. Disconnect the end of the connecting
rod at the rocker frame by removing the two capscrews and cap. See the drawing
below. You should now be able to remove the drive belt from the pulleys.
Install a new belt by reversing the removal procedure. Refer to the “Belt Tightening”
section for advice on how to adjust the drive belt tension.
REPLACING THE GAS SPRING
Remove the handle by loosening the setscrew in the hub. The handle side cover can
now be removed by removing the six slotted head screws holding it in position. See the
next illustration.

0711S20005-8
REPLACING THE GAS SPRING (Continued)
WARNING
THE GAS SPRING IS IN A COMPRESSED STATE, USE CARE WHEN
REMOVING IF FROM THE MACHINE.
To remove the gas spring, remove the push-on clip at the top of the gas spring by
prying it off with a screwdriver.
NOTE
The clips are not re-usable; a new one will be required.
After the clip is removed, the gas spring can then be pried off with a screwdriver, use
care noting the above warning. See the next illustration for additional information. At
this point, the shoulder screw securing the opposite end of the spring can be removed
freeing the spring.

0711S20005-9
REPLACING THE GAS SPRING (Continued)
To replace the gas spring, start by re-attaching the lower end of the spring with the
shoulder screw.
CAUTION
USE A LOCKING FLUID, SUCH AS LOC-TITE , TO PREVENT THE
SCREW FROM LOOSENING BECAUSE OF VIBRATION.
Using two people, grasp the spring as shown in the next illustration and slide the spring
back over the pin on the frame. Reverse the remaining removal steps to complete
assembly.
CAUTION
CARE MUST BE USED WHEN WORKING WITH THE GAS SPRING.
ALWAYS PUSH STRAIGHT DOWN OR SPRING DAMAGE MAY OCCUR.

LUBRICATION
Once a month put a drop of a food approved lubricant on the plastic links at the top of
the blade frames. Also add a drop or two to each bushing on the pusher drive cross
shaft and lever shaft. All other bearings are greased packed or sealed and seldom
need attention.
NOTE
Never oil or grease the motor.
CLEANING
Use a mild detergent solution to clean the exterior surfaces and empty the crumb tray
daily or as necessary. Periodically remove all guards and covers and brush or blow, if
compressed air is available, all foreign material from all surfaces, especially moving
parts.

MODEL 711 COUNTER TOP SLICER
0711S20006-1
ADJUSTMENTS
SLICES VARY IN THICKNESS
Remove rear inspection plate from the slicer. With a wrench loosen, but do not remove,
the hex head capscrews in the feet of each of the top and bottom blade frames.
Loosen the setscrews in the rocker frame fixed collars. See illustration below.
Gently tap the collar with a small mallet to the right or left until the blades are centered
in
the slots in the top guard. Tighten the setscrew and capscrews in the blade frame feet
securely. Replace the rear inpsection plate.
ADJUSTING THE GAS SPRING
CAUTION
FREQUENT ADJUSTMENT OF THE GAS SPRING IS NOT RECOMMENDED.
The gas spring must be removed and relocated to adjust its force. To remove the gas
spring, see “Replacing the Gas Spring” in the maintenance section. There are two gas
spring pins welded into the frame. The pin furthest from the front of the machine, (the
standard position), should be used whenever possible. The standard position gives a
gentle force at the beginning of the slicing operation, (when it is most needed), which
will allow the knives to start cutting and to prevent damage to the product. It also
provides the most force at the end of the stroke to allow the cradle to finish its upward
travel.
