INSTALLATION INSTRUCTIONS Removing the Slicer from the Shipping Skid After removing the carton you should find the basic slicer completely assembled and strapped to the shipping skid. Cut both straps to free the slicer from the skid. CAUTION THE SLICER IS HEAVY, USE PROPER TECHNIQUE WHEN LIFTING. KEEP BACK STRAIGHT, KNEES BENT, AND LIFT WITH LEGS.
Page 10
CASTER INSTALLATION INSTRUCTIONS Place blocks on the floor approximately (8) and (38) inches from the discharge side of the slicer, see the illustration below. Lower the holddown to its lowest position and tighten the adjustment knob to prevent the outfeed table from swinging out. With one person on each side of the slicer, gently lower the slicer onto the blocks.
Page 11
On all slicers equipped with either the Power Belt infeed chute option, or a Model 1179S bagger, a counter weight must be attached to the caster brackets on the right hand side of the machine, (as viewed from the outfeed side of the slicer). See the above illustration.
OPERATING INSTRUCTIONS CAUTION ALWAYS USE CARE WHENEVER WORKING NEAR THE CUTTING KNIVES. Adjusting the Gravity Feed Slicer’s Holddown Loosen the holddown adjustment knob. Adjust the holddown so that the product just clears the bottom edge of the holddown as it passes through the cutting knives. Tighten the holddown adjustment knob when the holddown is in the desired location.
Adjusting the Slicer for Product Length Using a typical product, adjust the infeed chute side guides by applying hand pressure. See the next illustration. Set the side guides approximately 1/8 inch wider than the longest expected product. 0797S20067...
Adjusting the Outfeed Side Guides on a Standard Outfeed Table Adjust the side guide extensions so that they are approximately 1/4 inch from the cutting knives. Loosen the outfeed guide adjustment knobs. Adjust the outfeed side guides to align with the infeed guides. See the illustration, which follows. Once satisfied with the location re-tighten the side guide adjustment knobs.
Operating a Gravity Feed Slicer Once the slicer has been properly adjusted for product clearance, the infeed chute may be loaded with the product to be sliced. Flipping the starting switch to the ON position will begin operation. Remove each sliced product from the discharge table as it is sliced. NOTE THE GRAVITY FEED SLICER’S OPTIMUM OPERATING EFFICIENCY WILL BE MAINTAINED BY ENSURING THAT THE INFEED CHUTE IS KEPT...

Operating the Gravity Feed’s Lever Actuated Last Loaf Pusher (continued) CAUTION THE KNIVES ARE EXTREMELY SHARP. DO NOT TOUCH MOVING OR STATIONARY KNIVES. Once the last loaf pusher has fed the product into the cutting knives as far as it can, it may be necessary to pull the product the rest of the way through the knives by hand.
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.
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 correct this problem.) The Blade Frames Are Knocking •...
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 swing out the discharge table to allow access to the drive area of the machine, then brush, blow, (if compressed air is available), or wipe all foreign material from all surfaces, especially from moving parts.
Removing the Blade Frames WARNING ALWAYS DISCONNECT THE SLICER FROM THE POWER SUPPLY BEFORE ATTEMPTING ANY TYPE OF MAINTENANCE TASK. Swing out the discharge table from the slicer. See the next illustration. Always start by removing the discharge side blade frame first. Both blade frames should be removed from the discharge side of the machine, (see the note below).
Page 21
Removing the Blade Frames (Continued) NOTE NEVER LOOSEN THE NUTS ON THE ECCENTRIC PINS OR ATTEMPT TO REMOVE THEM TO AID IN REMOVING THE BLADE FRAMES. Start by pulling the hairpin clip from the eccentric pin, located at the top of each blade frame, see illustration below, then slide the top link toward the eccentric pin’s mounting plate.
Page 22
Removing the Blade Frames (Continued) 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. Removal of the infeed side blade frame is accomplished in a similar fashion. However the chute guard must first be removed by removing the four knobs which hold it in place this will allow access to the locking cams.
Changing the Blades WARNING ALWAYS DISCONNECT THE SLICER FROM THE POWER SUPPLY BEFORE ATTEMPTING ANY TYPE OF MAINTENANCE TASK. CAUTION THE BLADES ARE EXTREMELY SHARP. ALWAYS HANDLE THEM WITH CARE. NOTE DO NOT INTERCHANGE THE TWO BLADE FRAMES. REPLACE THE BLADE FRAME TO THE SAME SIDE OF THE MACHINE AS IT WAS TAKEN FROM NOTE WHEN CHANGING BLADES FIRST NOTE THE DIRECTION THE SHARPENED...
Page 24
Changing the Blades (Continued) The new knife can be installed by reversing the removal procedure. A paper clip can be used to hold the knife in position on the lower pin to ease installation. See the illustration below. NOTE WHEN REPLACING ALL THE KNIVES, ALWAYS REMOVE THE CENTER KNIVES FIRST AND WORK TOWARD THE ENDS.
Tightening the Belt WARNING ALWAYS DISCONNECT THE SLICER FROM THE POWER SUPPLY BEFORE ATTEMPTING ANY TYPE OF MAINTENANCE TASK. CAUTION OVER-TIGHTENING THE DRIVE BELT MAY CAUSE BEARING OR MOTOR FAILURE. Remove the crumb tray from the slicer and swing out the discharge table. See the illustration below.
Page 26
Tightening the Belt (Continued) Loosen the lockbolt located below the belt adjustment mechanism. See the next illustration. Locate the adjustment bolt below the belt and turn it counter clockwise with a wrench to increase tension on the belt or clockwise to reduce tension on the belt. The drive belt should be just tight enough that, using moderate finger pressure, it would deflect about 3/8 of an inch when pressed midway between the motor drive pulley and the driven pulley.
Replacing the Belt WARNING ALWAYS DISCONNECT THE SLICER FROM THE POWER SUPPLY BEFORE ATTEMPTING ANY TYPE OF MAINTENANCE TASK. Referring to the “Tightening the Belt” section above, remove the crumb tray, swing out the discharge table, and reduce the tension on the belt by turning the adjusting bolt on the tightening mechanism clockwise until the belt can be slipped off from the motor pulley.
Adjusting the Blade Frames When Slices Vary in Thickness WARNING ALWAYS DISCONNECT THE SLICER FROM THE POWER SUPPLY BEFORE ATTEMPTING ANY TYPE OF MAINTENANCE TASK. Swing out the discharge table of the slicer. Loosen, but do not remove the two capscrews which secure the blade frame to the swing shaft, (see below).
Adjusting the Clearance Between the Blade Frames WARNING ALWAYS DISCONNECT THE SLICER FROM THE POWER SUPPLY BEFORE ATTEMPTING ANY TYPE OF MAINTENANCE TASK. The distance between the blade frames is adjusted by rotating the eccentric pins located above the blade frames. Two wrenches are used to do this. One wrench is used to keep the eccentric pin from rotating while the second is used to loosen the lock nut on the end of the pin.
