DESCRIPTION/SPECIFICATIONS

Description
The Oliver Model 732-R Counter Top Bread Slicer is of a compact, sturdy, time tested

design, which has been used in bakeries worldwide for many years. The machine is
easy to operate and can be loaded and unloaded from the front of the machine. It is
capable of slicing either hard crusted breads or soft-textured sandwich loaves with ease
and precision. After slicing, the bread can be easily packaged with the use of its
convenient front mounted bagging scoop. Its design will provide years of efficient,
trouble-free operation requiring a minimum of maintenance.

The Model 732-R Bread Slicer is of stainless, plated, and painted steel construction for
easy cleaning and maintenance. As with other Oliver slicers it is so easy to change the
blades, when that becomes necessary, that most operators will feel comfortable enough
to do it themselves eliminating the need of a service call.

Oliver Products Company, who has a reputation of serving the Baking Industry for over
70 years, backs this slicer.

INSTALLATION INSTRUCTIONS

Slicer Installation:
Before starting the Installation process make sure you observe the following three

caution notes.

CAUTION

THE SLICER IS HEAVY, USE PROPER TECHNIQUE WHEN LIFTING.

KEEP BACK STRAIGHT, KNEES BENT, AND LIFT WITH LEGS.

USE GLOVES TO PROTECT HANDS.

CAUTION

NEVER LIFT THE SLICER BY ITS SIDE COVERS.

CAUTION

BEFORE PLACING THE SLICER ON THE TABLE OR COUNTER MAKE SURE THAT

IT CAN SUPPORT THE SLICER’S WEIGHT WHICH IS APPROX. 250 POUNDS.

Select a location for your slicer which has a substantial mounting surface, (see the
caution note above), and which has electrical service compatible with the load the
machine will place on it as indicated on the electrical data plate of the machine.

Position the machine while it is still in its packaging as close as possible to the desired
end location. Expose the machine by removing the outer packaging and remove its
crumb tray. Using at least two people, (one in the front and one at the back of the
machine), lift the slicer from the resting surface of the packaging and set the machine
onto the counter or table as close as possible to the desired end location. Make final
location adjustments by sliding the machine to its desired location.

stopped, remove the product from the cradle. Use of the standard front mounted
bagging scoop will ease packaging of your product.

The bagging scoop’s bread stop is adjustable to accommodate various size loaves. To
adjust, apply pressure to the outside edges of the bread stop and slide it along the scoop
to the desired position.

TROUBLE SHOOTING

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 Emergency “Stop” button has been pushed. Twist the Red button in the
direction of the arrow on the button to release it to its run position.

• The lever is not being HELD

• There are bread crumbs beneath the cradle bracket or in the cradle guide tracks at

each side of the cradle bracket preventing it from going all the way down, which it
must do before the lower limit switch can be tripped.

• The lower limit switch is not adjusted properly. (Have a qualified service agent
adjust the switch.)

• The lower limit switch is defective. (Have a qualified electrician check and replace
the switch if required.)

• The problem is somewhere else in the electrical system of the machine. (Have a
qualified electrician find and repair the problem.)

Trouble Shooting (Continued)

The Slicer Will Not Start (Motor Is Humming)

CAUTION

DO NOT ALLOW THE MOTOR TO HUM WITHOUT STARTING.
OVERHEATING CAN PERMANENTLY DAMAGE THE MOTOR.

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 motor has failed. (Have it checked by a qualified electrician.)

The Slicer Stops Before Slicing is Complete

• The upper limit switch is not adjusted properly. (Have a qualified service agent
adjust the switch.)

The Slicer Does Not Automatically Stop Upon Completion of Slicing

• The upper limit switch is not adjusted properly. (Have a qualified service agent
adjust the switch.)

• The upper limit switch is defective. (Have a qualified electrician check and replace
the switch if required.)

• A bread crust or other foreign object is preventing the cradle from returning to the top
of its travel.

Trouble Shooting (Continued)

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

• 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.)

The Slicer Vibrates Excessively

• The drive belt is loose or worn. (See the “Maintenance” section of this manual under
“Tightening the Belt” or “Replacing the Belt” on how to make these corrections.)

• One or more of the bearings on the machine are failing. (Have a qualified service
agent check for defective bearings and replace them as required.)

• The pins, (two eccentrics and two regular), and links at the top of the blade frames
are worn. We suggest that these be replaced together. Mixing worn parts with new
will shorten the life of the replacement parts. Remember, after replacing the pins
and links the clearance between the blade frames must be re-adjusted. (See the
“Maintenance” section of this manual under “Adjusting the Clearance Between the
Blade Frames” on how to perform this adjustment.)

The Hand Lever Pulls Hard

• Check the Cradle guide tracks at each end of the cradle bracket for a build-up of
foreign material.

Trouble Shooting (Continued)

The Bread is Cutting Slowly or is Being Damaged

• The product you are attempting to slice is below the minimum height capacity of the
machine.

• You are pushing the lever of the machine in an attempt to speed slicing. This may
not only damage the product but may also damage the machine.

• If only certain products are cutting slowly the cutting speed you are experiencing may
be normal for that particular product.

• The knives of the machine have become worn, (dull). (See the “Maintenance” section
of this manual under “Changing the Cutting Knives”). Most owners can perform this
item of maintenance without calling a service company.

• The blades are not aligned properly. (See the “Maintenance” section of this manual
under “Adjusting the Clearance Between the Blade Frames” on how to perform this
adjustment.)

• The Gas spring may require adjustment or replacement. (See the Maintenance
section of this manual under “Gas Spring Replacement” on how to perform this task.)
