DESCRIPTION and SPECIFICATIONS
Description
The Oliver models 908-N, 918-N, and 938-N bread slicers are based on a compact, sturdy, time
tested reciprocating blade design paired with a powered bread pusher. These machines are
easy to operate and follow a top to bottom angled bread path. They are capable of slicing either
hard crusted breads or soft-textured loaves with ease and precision. After slicing, the bread can
be easily packaged with the use of a convenient front mounted bagging platform (908-N, 918-N)
or a bagging platform that deploys as the front outfeed cover is opened (938-N). These
machines will provide years of efficient and reliable operation requiring little maintenance.
The bread slicers are fabricated from stainless and painted steel construction for easy cleaning
and maintenance. As with other Oliver slicers, blade changing is easily done so many operators
feel comfortable enough to do it themselves when the need arises, eliminating a service call.
The first two model numbers represent counter top (908-N) and stand-mounted (0918-N)
configurations of the machine intended for professional use (ProServe). The third configuration
(0938-N) is a self-service version, stand-mounted with a front cover.
Oliver Packaging and Equipment Company, with a history of serving the baking industry for over
70 years, manufactures and supports these slicers.

INSTALLATION INSTRUCTIONS
Slicer Installation:
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 THE SIDE COVERS.
FOR STAND MOUNTED SLICERS, USE THE TOP FRONT OF THE STAND AND THE
OPENINGS IN THE BACK OF THE STAND TO LIFT THE SLICER.
FOR COUNTER-TOP SLICERS, USE THE BASE PLATE UNDER THE FRONT AND
REAR TO LIFT THE SLICER.
Stand Mounted Slicers:
Select a location with a level and solid floor with access to electrical service capable of
supplying the rated current for the machine. Avoid placing the machine in an aisle or
trafficked area where the bagging platform or outfeed cover maybe encountered by
persons or equipment.
Position the machine while it is still in its packaging as close as possible to the desired
location. Remove the outer packaging and strapping. Use at least four people or a fork
lift (place forks carefully under the stand) lift the slicer from the pallet surface and set the
machine onto the floor. Make final location adjustments by rolling the machine to its
desired location and lock the front casters.
Counter-Top Slicers:
Select a location for your slicer with a clean, level, and solid counter top capable of
handling the weight of the slicer with access to electrical service capable of supplying
the rated current for the machine.
Position the machine while it is still in its packaging as close as possible to the desired
location. Remove the outer packaging and strapping. It is advisable to place pieces
paper or cardboard as slip sheets on the counter surface to temporarily place the slicer
on to facilitate sliding the slicer into location, since the rubber feet grip surfaces. Use at
least three people to lift the slicer to counter height and slide it into position. Remove the
slip sheets after positioning.

button should illuminate if the machine has power. (Twist the knob to release the
button after checking.)
1.2. Verify that the machine is plugged in.
1.3. Verify there is 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.)
1.4. If the machine does not respond after the above verification steps, call Oliver
service.
2. The machine does not indicate “ready” (the green square around the start button
does not illuminate).
2.1. Check the display panel for any illuminated red symbols.
2.1.1. The cover open symbol is illuminated:
Close any open covers and replace any missing guards. See “Cover
open symbol is illuminated” topic.
2.1.2. The Emergency Stop button is pressed down and the ring is illuminated.
Twist the Red button in the direction of the arrow on the button to
release it.
2.1.3. The error symbol is illuminated.

3. The machine attempts to run but the blades do not move and a humming sound
is heard.
IMPORTANT! PRESS THE E-STOP BUTTON WITHIN SECONDS, OR THE MOTOR
WILL OVERHEAT AND DAMAGE MAY OCCUR.
3.1. The blades may be jammed on a partially cut loaf or foreign object.
Clear the machine by resetting the machine (ref. step 2.2) to get the pusher
out of the way, remove power to the machine, and pull the bread out of the
blades carefully, avoiding the sharp blade edges. Use a fork or other
instrument to distance hands from the sharp blades.
3.2. The blade drive mechanism may be jammed on a buildup of crumbs or foreign
material.
Empty the crumb tray and remove the outfeed table and inspect the crumb
chute area. Clear any material found.
3.3. The drive system is binding. (Have a qualified service agent check for defective
bearings or other restrictions to free movement.)
4. The error symbol is illuminated.
Note: This occurs when the pusher does not complete its full travel (either up or down)
within 30 seconds. Also see “bread is cutting slowly” topic.
4.1. If the pusher move has timed out because a loaf was difficult to cut and the bread
is partially cut and still in the blades:
4.1.1. Reset the machine by pressing and releasing the E-stop. Run the cutting
cycle again (push the green button) to clear the partially cut loaf.
If the bread does not clear after repeated attempts to cut it, the loaf may have been

908-N, 918-N, 938-N SIMPLE SLICE BREAD SLICERS
4.2. If the pusher move has timed out because the pusher had difficulty moving:
4.2.1. Examine it to determine if any material has jammed under it, behind it, or in
the slots along the side walls of the machine. If so, remove the jammed
material. If necessary, temporarily remove the pusher by loosening the two
hand knobs, clear the obstruction, and replace the pusher.
4.2.2. The drive system is binding. (Have a qualified service agent check for
defective bearings or other restrictions to free movement.)
4.3. The pusher move may have timed out because a switch may have been damaged
or needs adjustment. (Have a qualified service agent or electrician examine the
switches.)
4.4. The pusher move may have timed out because the blades have been damaged or
worn and no longer cut efficiently. Replace the blades.
5. The cover open symbol is illuminated.
5.1. The top cover (infeed cover) is not closed.

908-N, 918-N, 938-N SIMPLE SLICE BREAD SLICERS
6. The slicer damages the bread.
6.1. The top crust is ripped.
6.1.1. The loaf maybe too tall and drags on the hold downs or blade frames during
cutting. Consider orienting the loaf differently.
6.1.2. The hold downs may be coated with residue and drag on the loaf. Clean the
hold downs and blades (See “Cleaning and Maintenance” section of this
manual).
6.1.3. The hold downs may be bent or jammed with bread material, preventing
them from pivoting upwards freely. Inspect, straighten and clean as
necessary (See “Cleaning and Maintenance” section of this manual).
6.1.4. The hold downs drag on the loaf during removal. Consider using a pivoting
backwards rolling motion while removing the loaf to minimize the amount or
rubbing the top of the loaf does on the hold downs.
6.2. The bread rips apart when pulling it out of the slicer.
6.2.1. The loaf is not completely cut through.
6.2.1.1. The slicer may have timed out (see “error symbol is illuminated”
topic).
6.2.1.2. The loaf is too warm or soft and has been crushed and wrapped over
the top of the pusher resulting in the back top corner from being fully
pushed through the blades. Consider allowing the bread to cool and/or
orienting the loaf differently.
6.2.2. The loaf is too large or tall and drags on the hold downs. Consider orienting
the loaf differently.
6.2.3. The hold downs drag on the loaf during removal. Consider using a pivoting
backwards rolling motion while removing the loaf to minimize the amount or
rubbing the top of the loaf does on the hold downs.
6.3. The product being sliced is below the minimum height capacity of the machine and
is getting pinched under the pusher.
6.4. The loaf is crushed by the pusher.
6.4.1. The bread maybe too soft and warm. Consider allowing it too cool before
slicing.
6.4.2. The bread maybe too large or tall for the slicer opening. Consider orienting
the loaf differently.
6.4.3. Verify the hold down is free to pivot upwards and can fall back down freely
by lifting it from the front (outfeed) side of the slicer and releasing it. If not it
does not move freely it may be bent or contaminated. Straighten or clean as
necessary (See “Cleaning and Maintenance” section of this manual).
0908S20026
5-4
908-N, 918-N, 938-N SIMPLE SLICE BREAD SLICERS
7. 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.)
8. 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.)
9. The slicer vibrates excessively.
9.1. The blades may be coated with residue causing the loaf to stick to the blades.
Clean or replace the blades.
9.2. The drive belt is loose or worn. (See the “Maintenance” section of this manual).
9.3. 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.)
9.4. The pins, (four eccentrics and four regular), and links at the top of the blade frames
are worn. (See the “Maintenance” section of this manual).
10. The bread is cutting slowly.
Also see “the error symbol is illuminated” topic.
10.1. If only certain products are cutting slowly, the cutting speed may be normal for
those particular products. The bread may have an unusually high density, hard
crust, or weight that causes the slow cutting and may result in a time-out error.
10.2. The knives of the machine have become worn, (dull) or coated with sugar,
raisins, or other contaminants. (See the “Maintenance” section of this manual
under “Changing the Cutting Knives”). Many owners can perform this item of
maintenance without calling a service company.
10.3. 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.)
10.4.
The pusher force may be too low and needs to be adjusted.
10.5.
The bread is jammed (loaf is too large, or not loaded properly).
10.6. The pusher guide slides are contaminated and prevent it from moving smoothly
and evenly. (Clean and re-lube the slides).

Adjusting the Clearance between the Blade Frames
1. Open the top assembly and make sure the strut is safely in position (see topic).
2. Remove the side panels (see topic).
3. Turn the slicer motor over by hand and observe the behavior of the blade frames
to determine a course of action for adjustments. The blade frames should
appear centered in the side plate cutouts when they are at mid stroke (the tops of
the blades are even with each other). This position is also the location the blade
frames are the closest to each other and the best place to do adjustments.
4. The distance between the tops of the blade frames is adjusted by rotating the
eccentric pins at the ends of the blade frames. Two wrenches are used: 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. This nut secures the pin in position
once its proper location is determined.
Figure 7-17 Blade Frame Clearance Adjustment
0908S20027
6-18
908-N, 918-N, 938-N SIMPLE SLICE BREAD SLICERS
5. To adjust the eccentrics (with the lock nuts loosened), rotate the pins (it is
possible that both pins will need adjustment at the same time), until the blade
frames appear centered in the opening in the side plate and the knives of the
machine are in line (alternating blades should not appear to be in front of or
behind each other when viewed from the side). A straight edge may be used
from the dull side of the knives to aid in determining if the knives are in line.
6. Verify the blade frames are parallel with each other and the machine frame
members. When the eccentric pins are in the desired position tighten each of the
locknuts to secure the position of the eccentrics.
7. Check the blade frame clearance by turning the motor by hand. If the knives are
not inline, the blade frames may hit each other causing a knocking noise or the
cutting efficiency of the machine may be greatly reduced. Continue adjusting as
necessary.
8. Reverse steps 2 through 1 to return the slicer to working order.
