WARNING: THE SLICER KNIFE IS VERY SHARP.
EXERCISE EXTREME CAUTION WHEN WORKING
NEAR THE KNIFE.
WARNING: DISCONNECT THE ELECTRICAL
POWER TO THE MACHINE AND FOLLOW
LOCKOUT / TAGOUT PROCEDURES.
Fig. 3
Use a clean cloth soaked in a solution of mild detergent and warm water to wipe all surfaces of the
machine. Rinse using a fresh cloth and clean water. Use only products formulated to be safe on
stainless steel and aluminum.
To clean the Carriage Tray, close the Gauge Plate and pull the Carriage all the way toward the
operator. Unscrew the Knob on the Carriage Tray Support Arm (Fig. 3). Tilt the Carriage Tray
to the right until almost horizontal (Fig. 3). The Carriage Tray Support Arm can be cleaned while
in this horizontal position, or it can be removed by grasping with both hands and lifting straight
up. Once removed, the Carriage Tray Support Arm can be cleaned in a sink.
To re-assemble the Carriage Tray Support Arm, refer to page 7.
Remove the Top Knife Cover by rotating the Latch Knob (Fig. 3) counterclockwise and lifting it
free of the guide pins. Remove the Deflector (Fig. 1) from its mount below the slicer knife by
rotating it outward, away from the knife. Clean both Top Knife Cover and Deflector with warm
soapy water in a sink. Rinse with clean water.

Remove the Sharpener by pushing the Lock Lever to the left (Fig. 4). Tilt the right side up, clearing the
right guide pin, then lift the Sharpener up, clearing the left guide pin. Wipe out any residue remaining
inside the sharpener housing and clean the Sharpener in a sink. Do not soak. Rinse with fresh water.
Clean completely around the Ring Guard by working a moistened, folded paper towel between the Ring
Guard and Knife. Insert the towel at the base of the Ring Guard. Manually rotating the knife will allow
the towel to wipe the Ring Guard and the edge of the Gauge Plate as it follows the knife (Fig. 5).
Wash and rinse both sides of the knife by wiping outward from the center. Use a mild detergent or
sanitizer solution only. Never clean any part of the slicer with steel pads.

Do not exceed chemical manufacturer’s recommended
concentrations for detergent or sanitizer. Do not exceed
200 parts per million concentration of available chlorine.
For example, mixing 1 tablespoon of 5.25% sodium
hypochlorite bleach with 1 gallon of water yields a solution
containing 200 ppm of available chlorine. Solution with
concentration greater than 200 ppm will accelerate
corrosion of metals. Maximum exposure to sanitation
solution varies with temperature and concentration.
Rinse with clean water.
Reassemble the Sharpener to the mounting bracket by
sliding the left slot on the Sharpener over the left guide
pin on the bracket while tilting slightly (Fig. 6). Then,
press down on the right side of the Sharpener so the
locking hole fits over the right guide pin on the bracket.
Slide the Lock Lever to the right to lock the Sharpener in
position. Make sure the Sharpener is securely engaged
to the pins on the bracket.
Carefully reassemble the Top Knife Cover by putting it
in position (three guide pins). Lock by turning the Latch
Knob counterclockwise while lowering the Top Knife
Cover; then release the Latch Knob and turn it clockwise
until snug.
Replace the Deflector below the slicer knife:
Guide bottom of socket onto mount and rotate inward,
towards the knife.
NOTE: The last three digits of the slicer serial number
are etched on the Key (Fig. 7). Make sure the Carriage
Tray Support Arm stays with its own slicer, otherwise
proper clearances may not be maintained.

MAINTENANCE
KNIFE SHARPENING
TM
The Hobart Clean Cut
However, in high volume applications where it is a practice to sharpen the knife frequently, the knife
will be expended in a shorter time.
Sharpen only when necessary, usually when slice quality starts to degrade; prolonged or too
frequent sharpening results in unnecessary knife wear.
WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND FOLLOW
LOCKOUT / TAGOUT PROCEDURES.
Turn the Index Knob fully clockwise to close the Gauge Plate. Remove the Top Knife Cover by rotating
the Latch Knob counterclockwise and lifting it off the slicer. Thoroughly wash the area around the knife,
the exposed knife surfaces and the knife edge. Fat from meat or cheese should not be allowed to
transfer from the knife to the Sharpener.
Plug in machine power cord. With the carriage tray pulled all
the way toward the operator end of the machine, start the
slicer with your right hand by pulling the Start/Pause Knob
until the slicer starts and hold it out (do not release it). Pull the
Sharpener Handle fully toward the operator for 5 seconds
(Fig. 9). Slowly release the Sharpener Handle. Push the
Start/Pause Knob to turn the slicer off. If necessary, repeat
sharpening for another 5 seconds.
knife will provide long service in normal food retail or commercial kitchen use.
Unplug machine power cord. Wipe the slicer with a clean
damp cloth to remove any grinding particles. Replace the Top
Knife Cover.
LUBRICATION — Carriage Slide Rod and Sharpener
Use only Lubriplate FMO-200-AW food-safe lubricant,
supplied with the slicer. To apply oil, pull out the telescoping
tube on the oil bottle, aim the tube and squeeze gently on the
sides of the bottle. Apply 5 drops every month (depending on
usage) in the Wick Hole on the Carriage Transport; or, apply
5 drops directly on the Carriage Slide Rod on each side of the
Carriage Transport (Fig.10) once each month. After applying
the oil, move the Carriage Tray back and forth so the oil
spreads over the entire length of the slide rod. Also, apply 1
drop on both slots of the sharpener plunger and on the
sharpener shaft (Fig.
11).
OVERLOAD RESET BUTTON — MODEL 2912B
Push the reset button underneath the slicer near the rightfront foot if the carriage motor overloads.
