INSTALLATION INSTRUCTIONS CAUTION THE SLICER IS HEAVY, USE PROPER TECHNIQUE WHEN LIFTING. KEEP BACK STRAIGHT, KNEES BENT, AND LIFT WITH LEGS. USE GLOVES TO PROTECT HANDS. Removing the Slicer from the Shipping Platform Lift the slicer off the shipping platform with one person on each side of the slicer. Set the slicer down on a level floor. Using the shipping platform or other blocks, carefully lower the slicer to its side as shown below.
HAVE BEEN ORDERED WITH THE MACHINE. Installing the Rubber Feet Remove the rubber feet from the accessory package and insert the plugs into the holes in the leg bottoms, see below.

OPERATING INSTRUCTIONS CAUTION ALWAYS USE CARE WHENEVER WORKING NEAR THE CUTTING KNIVES. To operate the slicer, stand on the discharge side, grasp the lever with the right hand, see below, pull it down as far as it will go and hold it there. With the left hand place the loaf of bread in front of the pusher. While continuing to hold the lever down with the right hand move the left hand to the discharge side of the machine and pull the motor starting knob, see next illustration.
CAUTION THE KNIVES ARE EXTREMELY SHARP. DO NOT TOUCH MOVING OR STATIONARY KNIVES. The motor and slicer knives will stop automatically when the pusher comes to its full forward position. Remove the loaf from the table and bag or wrap the product. Use the same procedure for each loaf.
TROUBLESHOOTING WARNING ALWAYS DISCONNECT THE SLICER FROM THE POWER SUPPLY BEFORE ATTEMPTING ANY TYPE OF MAINTENANCE TASK, INCLUDING TROUBLESHOOTING. The Slicer Will Not Start (Motor Is Not Humming) • The machine is not plugged in. • There is no power at the outlet. (Check by plugging in a small working appliance, like a lamp. Check to see if a circuit breaker has tripped. If the circuit breaker has not tripped and the circuit is still not working have a qualified electrician check the circuit.
• The upper limit switch is not being made. (Adjust the limit switch screws as required to correct the problem, see above illustration.) The Slicer Will Not Start (Motor Is Humming) CAUTION DO NOT ALLOW THE MOTOR TO HUM WITHOUT STARTING. THE MOTOR CAN BE PERMANENTLY DAMAGED BY OVERHEATING. • The motor has failed. (Have it checked by a qualified electrician.) NOTE A SPECIAL NON-VENTILATED MOTOR MUST BE USED WITH THIS SLICER. • The drive system is binding.
Bread Slices Vary in Thickness • The blade frames are out of adjustment. (See the “Maintenance” section of this manual under “Adjusting the Blade Frames When Slices Vary in Thickness” on how to perform this adjustment.) The Blade Frames Are Knocking • The blade frames are out of adjustment. (See the “Maintenance” section of this manual under “Adjusting the Clearance Between the Blade Frames” on how to perform this adjustment.
MAINTENANCE WARNING ALWAYS DISCONNECT THE SLICER FROM THE POWER SUPPLY BEFORE ATTEMPTING ANY TYPE OF MAINTENANCE TASK. Cleaning Use a mild detergent solution to clean all exterior surfaces and empty the crumb tray daily or more often if necessary. Periodically remove both tables and the crumb chute and then brush, blow, (if compressed air is available), or wipe all foreign material from all surfaces, especially from moving parts.
Removing the Blade Frames (Continued) Always start by removing the discharge side blade frame first. Both blade frames should be removed from the discharge side of the machine. You should remove the discharge side blade frame completely from the machine before starting on the infeed side blade frame. However each is removed using similar procedures. NOTE NEVER LOOSEN THE NUTS ON THE ECCENTRIC PINS OR ATTEMPT TO REMOVE THEM TO AID IN REMOVING THE BLADE FRAMES.
CAUTION THE BLADES ARE EXTREMELY SHARP. ALWAYS HANDLE BLADE FRAMES WITH CARE. The blade frame can now be carefully lifted from the slicer. See below. The remaining blade frame can be removed in the same manner.
Replacing the Blade Frames Replacement of the blade frames is done by reversing the removal procedures. Ensure That the feet of the blade frames rest snuggly on the swing shafts and that you have included the belleville washers with the eye bolts. NOTE WHEN INSTALLING THE BELLEVILLE WASHERS, THEY MUST BE PLACED SO THAT THE CROWN IS UP AS SHOWN IN THE ILLUSTRATION BELOW.
When replacing the eye bolts turn them clockwise until moderate pressure is required to close the cam. If the cam is to easy to close rotate the eye bolt a half turn more in the clockwise direction and try to reinstall the cam. Repeat these partial rotations until moderate pressure is required to close the cam. If the cams are either difficult or impossible to close, rotate the eye bolt a half turn in the counter clockwise direction. Repeat until the cams can be closed using moderate pressure.
NOTE WHEN CHAINGING BLADES FIRST NOTE THE DIRECTION THE SHARPENED EDGES ARE FACING ON THE BLADE FRAME. THEY ARE FACING UP ON ONE FRAME AND DOWN ON THE OTHER. DO NOT CHANGE THIS DIRECTION. Place the blade frame on a flat surface. You may use the special knife tool, shown in the illustration below, or use a common set of pliers to depress the spring-loaded pin holding each knife. This will reduce the tension on the knife so that it may be easily removed.
WHEN REPLACING ALL THE KNIVES, ALWAYS REMOVE THE CENTER KNIVES FIRST AND WORK TOWARD THE ENDS. INSTALL THE NEW KNIVES AT THE ENDS FIRST AND WORK ALTERNATELY TOWARD THE CENTER. CAUTION NEVER PUT BLADE FRAMES IN THE SLICER WITHOUT KNIVES. Tightening the Belt CAUTION OVER-TIGHTENING THE DRIVE BELT MAY CAUSE BEARING OR MOTOR FAILURE.
Remove the crumb tray from the slicer. Locate the adjustment nut at the lower end of the motor mounting plate, see below. Turn the adjustment nut clockwise with a wrench to increase tension on the drive belt. To reduce tension, turn the adjusting nut counterclockwise. The drive belt should be just tight enough, using moderate finger pressure, to allow a 3/8 inch deflection halfway between the motor drive pulley and the driven pulley.
infeed and discharge tables are held in place by friction so pull the infeed table straight out and hard to separate them. Turn the adjustment nut, at the lower end of the motor mounting plate, counterclockwise with a wrench to loosen the drive belt, see “Tightening the Belt” above. Disconnect the end of the connecting rod at the rocker by removing the two cap screws and cap as shown below. The drive belt may now be removed from the pulleys The new belt can be installed by reversing the removal procedure.
Remove the discharge table from the slicer. Loosen, but, do not remove the two locking cams which secure the blade frame to the swing shaft. Remove the plastic plug over the set screw in the fixed collar, see below. Using an allen wrench, loosen, do not remove the set screw in the fixed collar. Using a ruler, (15” maximum), measure the distance between the blades. Gently tap the collar with a small mallet either to the right or left until the distances between the blades are equal.
To adjust the eccentric, once the lock nut is loosened, rotate the pin using the wrench used to hold the pin. Rotate the pin, (it is possible that both pins will need adjustment at the same time), until the knives of the machine are in line within a 1/32 of an inch, (alternating blades should not appear be in front of or behind each other when viewed from the side).
