General Information
1 General Information
1.1 Safety – Notes on the Warranty
Fully automatic models VA 802, VA 804 and VA 806 are fitted with safety equipment.
They have been tested for safety.
Nevertheless, if the machine is used improperly or not as intended, there can be
hazards to.
• The health of the user
• The machine and other property of the operator
All persons charged with installing, operating, servicing and repairing the machine must
• Be trained/instructed for the task.
• Follow these operating instructions to the letter.
1.1.1. Set-up and Instruction
Store and transport machines in their original packaging until they are set up.
The GRAEF dealer is responsible for set-up and start-up as well as for providing
instructions on how to operate, clean and service the machine.
Customer installation and start-up, incorrect operation, modifications
and removal of the safety equipment will invalidate our liability.
Important!
The installation and instruction must be confirmed by your authorised
GRAEF dealer.
!
Depending on the design, the slicing machines weigh more than 68 kg.
Two adults are required to lift and carry the machine.
The centre of gravity is in the rear third of the machine, where the motor is located.
Always lift and carry the machine by the machine housing.
x For longer company-internal transport routes.
Use a suitable handcart.
x Take off removable parts such as chain frame, tray and beater before transport
x Fasten the carriage by inserting paper or cardboard between the thumb and the
stop plate
x Set the slicing thickness below “0“ before transport by turning the slicing
thickness
5
General Information
1.1.1.1. Set-up site requirements
The base must fulfil the following requirements:
x It must be sufficiently stable, strong, level, flat and non-slip.
x It must be of sufficient height to allow slicing while standing.
x It must meet the space requirements listed in “Workspace“ (see Technical
Dimensions).
x It must be located away from busy corridors.
x It must not be close to any doors.
x It may not be in the swinging area of a door, nor in the entrance area of a door.
x When using Nirosta tables, Resopal supports or similar materials: Ensure that there is
no oil or grease on the surface.
x Ensure sufficient lighting of at least 300 lux
1.1.1.2. Unpacking the machine
Caution!
The machine may only be unpacked and set up by authorised customer service / sales
personnel. Check the required working space (with the machine switched off!):
!
• Hold the last slice clamp by the handle.
• Lift up the last slice clamp
• Move the carriage all the way forward and back
If the carriage or last slice clamp comes into contact with other objects, you must provide
a larger work space.
1.1.1.3. Electrical connection
x Check if the local supply voltage conforms to the specifications indicated on the
rating plate. If it does not, you may not connect the machine.
x The electrical socket must comply with the VDE regulations (Association of German
Electricians).
6
General Information
x For rotary current models (400 V), check that
the running direction of the blade is correct.
x The blade must move downwards in direction
of the carriage as shown in the illustration.
x If the running direction is incorrect, use a
screwdriver to turn the phase change in the
network adapter plug by 180°.
x Moisture: Degree of protection IP 33! High humidity or condensation can damage the
machine.
x Lay and connect the power supply cord so that no-one can fall or trip over it.
x The machine is designed for use in sales rooms.
1.1.2. Proper Use
The fully automatic slicers VA 802/804/806 are designed
to slice only the following types of food:
Sausage / meat / ham / slicing cheese
Do not attempt to slice frozen foods.
Do not attempt to slice vegetables or food that has bones.
Remove any metal braces on the goods to be sliced.
Unauthorised modifications to the machine are prohibited for safety reasons.
The operating, maintenance and service instructions
described in this instruction manual must be strictly observed.
1.1.3. Natural Wear
Natural wear is not covered by our warranty or liability.
7
General Information
1.1.4. Potential Sources of Danger
Caution!
Danger of injury!
Never reach into the area of the moving carriage.
Caution!
Danger of injury!
The blade is sharp and can sever body parts.
Your fingers, and especially your thumb, are at risk. For this reason, never reach into the
space between the last slice clamp and the blade or the limit stop if the limit stop plate is
not completely closed. When the machine is not in use, the stop plate must always be set
to the zero position.
Caution!
Injury through electric shock.
The machine operates with a mains voltage of 230 V or 400 V and must therefore not be
opened. The protective earth conductor system must be connected in any case, otherwise
there is a risk of severe electric shocks.
Caution!
Hazards posed by the chain frame.
Never put your hands near the chain frame during operation. The spikes can cause
serious injury.
The placing arm that removes the sliced food moves very quickly and can injure hands or
other parts of the body in case of contact.
Caution!
Risk of injury.
In the area of the food holder, there is a risk of injury posed by the spikes and the food
holder suddenly dropping when inserting the product.
Caution!
Risk of injury.
When mounting parts which can be removed for cleaning.

General Information
1.1.5. Workplace
Only operate the machine if you are standing in a secure position.
Stand in front of the machine so that the power on/off button is facing you.
Keep your workplace clean at all times.
The machine must be positioned on a solid, even and stable base that can support the
weight of the machine and the dynamic forces of the moving parts.
1.1.6. Authorised Users
The machine may only be operated by people who:
Have read and understood the operating instructions
Have been instructed thoroughly by the operator
Have been instructed on the dangers of the machine and the hygiene regulations
The machine may only be serviced and repaired by specialists.
Take precautions to prevent unauthorised persons from using, cleaning or servicing the
machine.
1.1.7. Protective Clothing and Equipment
Wear close-fitting clothes when operating the machine. Please also observe the hygiene
regulations.
When executing cleaning or maintenance work in the area of the knife, be sure to wear
cut-resistant gloves with pulse protection.
When transporting the machine, be sure to always wear steel-toe boots.

3.2. Programmes
You can either work in the standard mode or access specially defined placing
programmes through PLU. The standard mode makes it possible to combine basic
functions such as stacking, long-shingling, cross-shingling or circular shingling with the
following parameters: number of slices, stroke speed and number rows/stacks.
3.2.1. Slicing in the Standard Mode (PLU=0000)
3.2.1.1. Stackinging
The stacking function enables stack heights of up to 60 mm.
This function is selected by simply pressing the stack button. The display shows the
symbol for stacking. You can preset the number of slices using the plus/minus buttons.
If multiple stacks are desired, you can increase the number of stacks with the “X“ button.
Up to 4 stacks are possible.
When making preparations, it is recommended to set the slice counter to “000”.
In this way, the maximum stack height is always achieved.
If stacks are to be generated on portioning units (foils, PE trays, foam trays, trays etc.),
you can enter the outer dimensions of the portioning units L x W for central placing.
(Option: the machine then uses the calibre recognition option to calculate the best
placing point).

Example:

Select function
“Stacking”

= 4 stacks
3.2.1.2. Long shingling
The long fanning function is for placing the individual slices in rows parallel to the stop.
The number of rows can be set using the “X“ button. Up to 4 rows are possible with the
standard programme. When making preparations, it is recommended to set the slice
counter to “000”. The machine then fans multiple layers on top of each other.
If rows are to be generated on portioning units (foils, PE trays, foam trays, trays etc.), you
can enter the outer dimensions of the portioning units L x W for central placing. (Option:
the machine then uses the calibre recognition option to calculate the best placing point).
