CLEANING

This machine must be thoroughly cleaned and sanitized after each day’s operation or after being idle

for an extended period of time.

WARNING: THE SLICER KNIFE IS VERY SHARP.

EXERCISE EXTREME CAUTION WHEN WORKING

NEAR THE KNIFE.

WARNING: UNPLUG MACHINE POWER CORD

AND TURN THE INDEX KNOB FULLY CLOCKWISE

BEFORE CLEANING THE SLICER.

Use a clean cloth soaked in 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 or

aluminum.

To clean the Carriage Tray, close the gauge plate and pull the Carriage all the way to the front. Unscrew

the Knob on the Carriage Tray / Support Arm (Fig. 4). Tilt the Carriage Tray / Support Arm to the right

until almost horizontal (Fig. 4). 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. NOTE: The last three digits of the slicer serial

number are etched on the Key (Fig. 8) so you can make sure the Carriage Tray stays with its own slicer.

Remove the Top Knife Cover by rotating the Latch Knob (Fig. 4) counterclockwise and lifting it free of

the guide pins. Remove the Deflector (Fig. 1) from its mount below the slicer knife by rotating

downward. Clean both Top Knife Cover and Deflector with warm soapy water in a sink. Rinse with

clean water.

Fig. 5 Fig. 6

Remove the sharpener by pushing the Lock Lever to the left (Fig. 5). 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. 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 rotate the knife and the

towel will wipe the Ring Guard and the edge of the Gauge Plate as it follows the knife (Fig. 6).

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

Fig. 4

2912 Slicer Technical Manual Page 12 of 72

– 7 –

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 concentrations 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. 7). 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 to the left while lowering the Top Knife Cover;

then, release the Latch Knob and turn it to the right until

snug.

Replace the Deflector below the slicer knife:

Guide

bottom of socket onto mount and rotate upwards.

Make sure the digits etched on the Key (Fig. 8) match

the last three digits of the slicer serial number. To

reinstall the Carriage Tray / Support Arm: Hold it with

both hands and lower it so the Key at the bottom of the

Support Arm fits into the slot of the Carriage Pivot

(Fig. 8). The Carriage Tray should rest almost horizontal

(Fig. 4). Return the Carriage Tray to the Gauge Plate by

tilting to the left. Turn the Knob on the Carriage Tray /

Support Arm clockwise until snug.

The model 2812 slicer has a Cleaning Leg underneath

the machine. To engage the Cleaning Leg, raise the

front of the slicer by lifting the front of the slicer base.

The Cleaning Leg will swing straight down. Pull the

Cleaning Leg all the way to the front so the slicer is

completely supported before cleaning underneath

(Fig. 9).

To clean under the model 2912 slicer, raise the Lift

Lever past center to its stop (Fig. 10). After cleaning,

return the slicer to its normal position by slowly retracting

the Lift Lever.

DO NOT wash any slicer components in a dishwasher.

DO NOT immerse slicer base or motor in water.

If using a chlorinated sanitizing solution, dilute per manufacturer’s guidelines. Rinse with fresh water.

NOTE: Failure to follow use, care, and maintenance instructions may void your Hobart warranty.

MAINTENANCE

KNIFE SHARPENING

The Hobart cast stainless steel knife will provide long service in normal food retail or commercial

kitchen use. However, in high volume applications where it is a practice to sharpen the knife frequently

or even daily, the knife will be expended in a shorter time.

Sharpen only when necessary; prolonged or too frequent sharpening results in unnecessary

knife wear.

WARNING: UNPLUG MACHINE POWER CORD.

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 fully forward, start the slicer with your right

hand by pulling the start switch forward and holding

it out. If the sharpener handle is the type that does

not hang downwards, pull it fully forward for 5 seconds

(Fig. 11). If the sharpener handle does hang

downwards, lift it with your left hand until horizontal

and pull forward for 5 seconds (Fig. 11). Slowly

release the sharpener handle. Release the switch

knob to turn the slicer off. If necessary, repeat

sharpening for another 5 seconds.

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

Lubricate the Carriage Slide Rod with Lubriplate

FMO-200-AW oil (supplied). Either squirt 8 – 10

drops every 2 – 3 months (depending on usage) in

the Wick Hole on the Carriage Transport (Fig.12).

Or, once monthly, apply 4 – 5 drops directly on the

Carriage Slide Rod on each side of the Carriage

Transport (Fig.12).

To apply oil, pull out the telescoping tube on the oil

bottle, aim the tube, and squeeze gently on the

sides of the bottle. After applying oil, move the

Carriage Tray back and forth a few times so the oil

spreads over the entire length of the slide rod.

OVERLOAD RESET BUTTON — MODEL 2912

Push the reset button underneath the slicer near the right-front foot if the carriage motor overloads.
