DESCRIPTION/SPECIFICATIONS
Description The Oliver Variety Slicer is a compact, sturdy, time tested design, which has been used
in bakeries world wide for many years. It is easy to operate and allows the slicing of virtually all varieties of bread, quickly and cleanly, with a spring fed pusher that gently moves the product through the knives followed by a automatic shut off. Its design will provide years of efficient, trouble-free operation requiring a minimum of maintenance.
The Variety Slicer is of stainless steel, plated, and painted construction for easy cleaning and maintenance. The knives can be replaced, by most operators, without the need of a service call.

INSTALLATION INSTRUCTIONS
CAUTION

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.
NOTE
PERFORM THE FOLLOWING DEPENDING ON WHICH OPTIONS
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. Carefully restore the machine to the upright position.
Installing Optional Casters
Remove the casters, caster brackets and hardware from the accessory package. Insert the studs of the brackets, see figure below, through the holes provided on the base of the slicer. Secure the brackets with the lock washers and hex acorn nuts. Press fit the casters into the brackets as shown below. Carefully restore the machine to the upright position.
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. Allow the right hand to raise slowly with the lever until the loaf contacts the slicer blades. After the knives have pierced the crust remove your right hand from the lever allowing the pusher to move the loaf through the knives.
CAUTION
NEVER PUSH THE HAND LEVER.
DOING SO MAY RESULT IN DAMAGE TO THE MACHINE’S COMPONENTS.
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 motor switch overload has tripped. (To reset push firmly in the direction shown on the switch nameplate.)
• There are bread crumbs in the motor starting switch. (Have a qualified electrician disassemble the switch and clean it.)
• The switch arm on the Switch Trip Mechanism is bent. (A qualified service agent can bend the arm to correct the problem, see the illustration below.)
• The switch trip mechanism is binding. (Clean the mechanism and lubricate its pivot point, see above illustration.)
• 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. (Have a qualified service agent check for defective bearings or other restrictions to free movement.)
• There is mechanical interference between other parts of the slicer. (Have a qualified service agent evaluate the machine for adjustment or replacement of defective parts.)
The Slicer Starts Without Pulling the Knob
• The switch arm on the Switch Trip Mechanism is bent. (A qualified service agent can bend the arm to correct the problem, see the illustration in the “The Slicer Will Not Start” section above.)
The Slicer Does Not Stop When Slicing is Complete
• Either one or both of the upper and lower limit switch screws on the limit switch trip mechanism are out of adjustment. (Adjust the limit switch screws as required to correct the problem, see the illustration in the “The Slicer Will Not Start”, section above.)
The Slicer Stops Before Slicing Starts or is Complete
• The lower limit switch screw on the limit switch trip mechanism is out of adjustment. (Adjust the screw as required to correct the problem, see the illustration in the “The Slicer Will Not Start”, section above.)
• The switch trip mechanism is binding. (Clean the mechanism and lubricate its pivot point, see the illustration in the “The Slicer Will Not Start”, section above.)
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.
Lubrication
Once a month, more often during heavy use, put a drop of food approved lubricant on each of the pivot points of the plastic links at the top to the blade frames. Also add a drop or two of the same food approved lubricant to the switch trip mechanism pivot point, pusher lever and yoke pivots. All other bearings are either grease packed or sealed and seldom need attention.
NOTE
NEVER OIL OR GREASE THE MOTOR.
Removing the Blade Frames
To remove the blade frames you must first remove the infeed table, crumb chute, and discharge table. First remove the four black knobs securing the tables, (see the illustration below). In addition to the knobs the infeed and discharge tables are held in place by friction so pull the infeed table straight out and hard to separate them.
