1 General Information
1.1 Safety – Notes on the Warranty
The semi-automatic models HA 800 and HA 810 are equipped with safety devices. They
have been tested for safety.
Nevertheless, hazards cannot be entirely excluded if the machine is used improperly or
not as intended.
These hazards may endanger:
• 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 are excluded from our area of liability.
Important!
The installation and instruction must be confirmed by your authorised
GRAEF dealer.
The slicing machines weigh approx. 56 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.
!
General Information
6
x Secure the carriage by inserting paper or cardboard between the thumb guard and
the stop plate.
x Set the slicing thickness below “0” by turning the slicing thickness control to the limit
position.
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 Data).
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.
!
General Information
7
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 (Association of German Electricians)
regulations.
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 HA 800 / HA 810 semi-automatic slicers are exclusively intended
for slicing only the following types of food:
sausage / meat / ham / cheese.
Do not attempt to slice frozen foods.
Do not attempt to slice vegetables or food with 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.
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.
General Information
9
Caution!
Risk of injury.
In the area of the food holder, there is a risk of injury posed by the spikes an the food
holder suddenly dropping when inserting the product.
Caution!
Risk of injury.
When mounting parts which can be removed for cleaning.
1.1.5 Workplace
Only operate the machine if you are in a 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
who have been instructed thoroughly by the operator
who have been instructed on the dangers of the machine and the hygiene regulations.
The machine may only be serviced and repaired by authorised 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 Programs
You can either work in the standard mode or access specially defined placing programs
using PLU. The standard mode makes it possible to combine basic functions such as
stacking, long-fanning, cross-fanning or circular fanning with the following parameters:
number of slices and number rows/stacks.
3.2.1 Slicing in the Standard Mode (PLU 0000)
3.2.1.1 Stacking
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 +/- 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 only HA 800: the machine then uses the calibre recognition option to calculate
the best placing point.)
Other Operating Controls
Slice thickness control
x Sets the slice thickness.
x Sets the limit stop lock (carriage removable)
x Sets the sharpening mode (completely opened)
Last slice clamp
x Clamps and feeds the food to be sliced to the blade.
Guide rail
x Fixes food product on the carriage.
x Calibre scanning
x Optimum use of placing surface

3.2.1.2 Long Fanning
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 program. 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
only HA 800: the machine then uses the calibre recognition option to calculate the best
placing point.)
