YOUR COFFEE GRINDER N° 4
• The N° 4 coffee grinder is designed especially for hotels, restaurants, community
catering, for the drawer version, and for coffee roasters and roasted coffee outlets for
the "bag grip" version.
• The robust frame of the appliance is made of cast aluminum and painted metal. The
transparent hopper is made of transparent polycarbonate transparent and contains 1
kg beans. The appliance is delivered with a "bag grip" system as standard (maximum
bag height: 280 mm), but on request there is also a model with a drawer to collect
the ground coffee (capacity 800 g).
• A button for adjusting the fineness of the grind caters for all types of coffee grind (fine
grind, espresso, filter coffee, medium or coarse grind).
• The special hardened steel grinding wheels (Ø 63.5 mm) guarantee a fine and even
grind.
ELECTRICAL CONNECTION
The appliance’s power supply is available in two voltages:
• 220-240V 50 Hz single phase
• 220-240V 60 Hz single phase
• 100-120V 50/60 Hz single phase
Line protection: the appliance should be connected to a standard 2-pole + earth electric
socket. The installation should be fitted with an RCD and a fuse rated
at 16A.
TAKE CARE:
• Before plugging the appliance in, check that its operating voltage matches your
power supply and the value featured on the warranty sheet supplied with the
appliance or on the rating plate underneath the appliance.
• If the power cable is damaged, it should be replaced with a special unit available
from SANTOS or a SANTOS-approved dealer.
Note: You will find it easier to understand the next few paragraphs if you
refer to the diagrams at the end of this manual.

Using the COFFEE GRINDER N° 4 (fig. A)
ADJUSTING THE GRIND
• Turn the grinding-wheel gap adjuster button (6) clockwise for a coarser grind and
anticlockwise for a finer grind. The factory setting is for the finest grind, with the
grinding wheels nearly touching each other.
SERVICING
• Clean the coffee outlet, the coffee-bean holder and the grinding mechanism from
time to time. Always turn the appliance off, i.e. switch (13) on position 0, and unplug
it.
• Cleaning in a jet of water or a high pressure spray is prohibited.
• The base (11) must not be immersed in water.
REPLACING THE GRINDING WHEELS
IMPORTANT: always change both grinding wheels (17) at the same time.
The 2 grinding wheels are identical and can be fitted equally either on the moving plate
(18) (moving grinding wheel) or on the cast metal adjustment block (19) (fixed grinding
wheel).
1. Stop the machine by putting the switch (13) to "0" and disconnect the power supply
cord.
2. Close the shutter (3) on the bean hopper (2). Take off the bean hopper (2).
3. Turn the grinding wheel gap adjuster button (6) clockwise until it comes to a halt at
the “COARSE” setting."
4. Unscrew the nuts (16) and remove the whole grinding unit (15), to gain access to the
grinding wheels.
5. Change the grinding wheels (3 fastening screws) after carefully cleaning the
supporting surfaces.
TAKE CARE: The slightest small coffee particle under the grinding wheel may
prevent the machine from operating correctly. It is recommended that the grinder
body is cleaned with a compressed air jet or a dry brush.
6. Reassemble the grinding unit (15) and adjust the grinding gap to its minimum setting.
TAKE CARE
• Before tightening the fastening nuts (16) on the grinding unit (15), check that the dial
(4) of the grinding wheel adjuster button (6) is set to “COARSE”"
This precaution is essential to prevent any risk of the grinding wheels being brought
too close to each other, which could cause damage to the grinding unit.

4 FR 1.0 - 04 2004 5/14
ADJUSTING THE MINIMUM GAP BETWEEN THE GRINDING WHEELS
This should be done after replacing the grinding wheels.
1. Plug the appliance in and run it empty.
2. Unscrew hexagon socket screw (7) on the dial (4) using a 2-mm Allen wrench.
Check that the dial (4) is free to rotate without turning button (6).
3. Turn button (6) anticlockwise until the grinding wheels come into contact (a slight
sound of friction will be heard) then back one notch in the reverse direction.
ATTENTION
This is a delicate operation, and prolonged contact between the grinding wheels
should be avoided, since this could damage them.
4. Turn the appliance off by placing switch (13) on "0".
5. Without moving the button (6), place the dial (4) on the "FINE" position then tighten
the hexagon socket screw (7) fully home.
6. Run the machine empty to check that the grinding wheels rotate without touching
each other on the finest setting. If this is not the case, repeat the above procedure.

Safety / Maintenance / Spare Parts
MOTOR OVERLOAD SAFETY FEATURE:
If the motor is blocked (foreign body, something too hard), the excess current protection
device (14), located under the appliance will be triggered automatically and cut off the
electrical power to the motor.
• Set the On / Off switch (13) to "0" position, disconnect the appliance.
• Correct the fault, then press the excess current protection button (14)
• Press the On/Off switch (13) (position I).
If the problem persists, switch off the power supply to the machine (unplug the cord from
the mains socket) and call in the maintenance service or contact a SANTOS approved
dealer.
MAINTENANCE
Before carrying out any work on the appliance, it must in all cases be unplugged from the
mains power supply and the motor start capacitor discharged.
Discharging the capacitor:
Use a screwdriver with insulated handle to touch the 2 connectors on the capacitor
(13). An electric arc should be produced, showing that the capacitor has discharged.
SPARE PARTS
IMPORTANT: It is prohibited to use spare parts other than those certified made by
SANTOS
This machine requires no particular maintenance because the bearings are lubricated for
life.
If servicing is necessary to replace any parts such as the electrical components, seals or
any others, refer to the list of components (see the exploded view at the end of the
manual).
For any orders for spare parts (see the references on the exploded view at the end of
the manual), quote:
1. the type,
2. the appliance serial number
3. and the electrical specifications noted underneath the appliance.
WARNING
1. Never use this machine to grind anything other than roasted coffee beans.
2. Remove from the coffee beans any foreign bodies which may damage the
grindstones (metal staples, stones, etc.).

Troubleshooting
Identify the exact reason the appliance stopped.
In every case: If the problem persists, switch off the power supply to the machine
(unplug the cord from the mains socket) and call in the maintenance service or
contact a SANTOS approved dealer.
The machine will not start:
• Check: the mains power supply and the condition of the power supply cord,
• Note: the switch should be lit when on the "1" position.
• Check that there are no foreign bodies stuck between the grinding wheels.
The machine stops because the motor has overheated:
(the metal casing around the motor unit is hot)
Models110-120V 50/60Hz only
In the event of overheating, the motor stops.
The overheating protection system resets automatically; wait for the motor to cool (15 to
30 minutes), before restarting the machine.
The machine stops because of an overload:
If the motor is blocked (foreign body, something too hard), the excess current protection
system (14), located under the appliance will be triggered automatically and cut off the
electrical power to the motor.
• Set the On / Off switch (13) to "0" position, disconnect the appliance.
• Correct the fault then press the excess current protection button (14)
• Press the On/Off switch (13) (position I).
If the problem persists, check the following points:
• Check that the grinding wheels do not touch each other.
• Check the state of wear of the grinding wheels (grinding too fine with worn grinding
wheels can result in a motor overload like this)
• If there are no foreign bodies preventing the appliance from working, then check
and replace the motor starter relay then the capacitor.
