MECHANICAL PADDLE
Introduction:
The La Marzocco Paddle is an innovative device which controls coffee brewing through an
external lever, activated by the barista to pre-infuse the coffee ground on one or more groups
simultaneously.
The lever lifts a shaft into the inner valve from the off position to the pre-infusion position and
ends with extraction.
With the La Marzocco mechanical Paddle, the barista has a direct impact on every espresso he
prepares, by manually profiling each extraction.
Thanks to the La Marzocco Paddle, it is now possible to:
? pre-infuse at main pressure shifting the mechanical valve inside the group head
? pre-infuse at main pressure on all groups at the same time, even when the pump is
running
? manually adjust the water flow on the coffee puck
This technical document is specific to those machines that are equipped with the Paddle. It is
to be used in addition to the manual you already have on hand in regards to each of our
machines, including the Linea, FB/70, GB/5, FB/80, Mistral and GS/3.
We would like to highlight our warning about the machine's technological system, which is
half electrical and half mechanical, reminding experts to proceed caution and work carefully.

How to maintain the O-rings of the body valve:
There are three O-rings inside the Paddle, separeted by two spacers, all
securely kept in position by a cylindrical cap (fig. 1).
It could happen that after a long period of intense operation, the Paddle
become gradually stiff. In this case, it is necessary to lubricate (fig. 3) the
shaft, part# A.5.003, using a small brush and the grease provided with the
spare parts kit. This will make the shaft glide more smoothly on part#
A.1.014.

The O-rings, which are employed in many mechanical applications, are
commonly used as seals. Substitution is rarely necessary and is most likely
required only when dismantling all spare parts for the eventual cleaning of
mineral deposits.
fig.1
Since its wear is relatively limited, after an extended period of time it may be
necessary to change the O-ring part# H.1.011 strictly following the
instructions here below and using the adequate remover “complete O-ring
remover assembly”(fig. 2), part# Ut004.

Instructions to substitute the O-rings H.1.011:
Dismantle all spare parts as described below:
Before any maintenance and/or cleaning operations, turn the main switch, which is located on the front
left of the machine, to the “0” or OFF position, and disconnect the machine from the electrical supply by
unplugging the cord or by switching off the relative circuit breaker. For any cleaning operation, follow only
those instructions from the standard manual which come with the coffee machine.
Close the water valve that supplies the machine and move the “Paddle” lever to the brewing position, with
the paddle placed all the way to the left until boiler pressure drops to 0 atm.
Dismantle all spare parts as described below:

1.
Remove the handle and the lever.
2.
Loosen (without removing the nut) item
A.4.003 (fig. 4).
3.
Remove F.3.020 by unscrewing the bolts,
placed on the side of the bracket, L120/2 (fig. 5 )
and
remove together with items A.1.014
and A.4.003.
4.
Remove in order: F.4.008,
F.4.009, A.5.003, A.1.010, F.4.010.
5.
At this point, item A.1.015 is visible and
removable (fig. 6).

The remover (fig. 8) works as follows:
While holding item “3” still carefully rotate (tighten) item “4” in a clockwise fashion. Item “2” will push against the
4 wings of the tip at the end of item “3”, and “spread them out”. In turn, the tip will grasp the bushing – O-rings and
spacers. To facilitate the “release” of these latter parts, it is necessary to close the tip by “unscrewing” item “4”
while holding “3” still.

Tighten the first nut at the top of the shaft of the remover to push the pin (fig. 9, 10).

8.
Bring the weight of the remover towards the
upper part with a firm, yet not too strong of a j o l t
(fig. 11).
9.
Remove the remover together with the bushing
O-ring and spacers.
10.
To replace the new O-rings, it is enough to
insert the components on the shaft, item
A.5.003, in the following sequence:
bushing (B.2.015)– O-ring (H.1.011) – spacer
(B.2.014) – O-ring (H.1.011)- spacer ( B.2.014) –
O-ring (H.1.011), lubricate with silicone grease
and reassemble the shaft in its place (fig. 12).
NOTE: before inserting the O-rings check if the
inside of the body valve is free of dirt.
11.
Put the thumb on the top the bushing and pull
out all the O-ring and spacers togheter.
12.
Reassemble, beginning with cap A.1.015
(fig. 13).

Place the entire “paddle”, including the central shaft A.5.003 as follows:
F.4.010, A.1.010, A.5.003, F.4.009, H.1.016, F.4.008, A.1.014, F.3.020, A.4.003 but tighten
it lightly, L120/2, A.4.005.
14.
Reassemble bracket C.1.067, complete with its micro-switch.
15.
Reassemble lever F.3.023 and its related handle.
16.
Reassemble lever F.3.023 above A.1.010 – push the shaft A.5.003 downwards and, while
holding it pressed downwards, move the lever F.3.023 to the right, to the resting position
the Paddle (drain position).
17.
Tighten nut A.4.003.
18.
In this configuration, the micro-switch, which activates the pump, is placed on the cap,
item L103/P, the back,
with bracket C.1.067 , thereby making possible both
horizontal and vertical regulation so that pin A.5.005, which is attached to item A.1.010, can
activate the pump during the brewing phase.

Instructions to disassemble and reassemble the body valve and restrictor:
The following procedure is useful for substuiting the gaskets
of the body valve or cleaning or replacing the flow restrictor
1.
Remove all parts of the mechanical valve placed
onto the cap, L103/P (fig. 14), L120/2 and L120/2A.
2.
Remove the banjo bolt which holds the cap
and the bajonet ring (fig. 15).
3.
Loosen, but do not remove, the fitting of the
valve inlet tube T.1.101(fig. 16), while holding with
the cutted cap the body valve.
4.
Loosen and disconnect the fitting of the valve
exhaust tube T.1.100
5.
Carefully slide the body valve out of the group
6.
Now it is possible to regenerate the body valve
and replace the O-ring gaskets as described in the
previous section, “Instructions to substitute 0-rings
H.1.011” and H1.010.
fig. 14
fig. 15
fig. 17
fig. 16
Notice: It is very important to keep the valve inlet tube fitting linked to the body valve to avoid its falling into the
coffee boiler. On the contrary, the exhaust valve tube is connected to the side of the group by the nut, L100/5,
besides the other end tight to the body valve.
We suggest a cap sectioned to firmly hold the body valve while you tighten the inlet valve tube and exhaust tube
fitting.

7.
Inside the group there is an adaptor, A.5.008, (fig. 16
which connects and seals together the body valve to
the group.
At the bottom, there is an O-ring, H.1.010, to seal
the adaptor to the group which we suggest you
replace each time you open the group.
8.
With the body valve in your hand, it is possible to
clean or replace the synthetic ruby restrictor (fig. 17).

Instructions to adjust the valve position:
1.
Loosen the nut A.4.003, (fig. 18).
2.
Push down the shaft and keep the lever on the off
position and then tighten the nut (fig. 19).
fig. 18
fig. 19
3.
fig. 20
Check all posistions: when the lever is in the off position,
there is no leaking from the screen diffuser or through the
drain box where the drain tube is connected. When the
lever is in the middle position, water flow from the screen
diffuser is very weak. When positioned to the left, the
motor pump
is on and the pressure for brewing
coffee is at 9 bar.
Notice: The angular position of A.1.014 determines where the lever begins to lift the shaft, therefore when
nut A.4.003 is loosened, it is possible to calibrate the three Paddle positions as described above (fig. 20).

Instructions to adjust the position of the microswitch:
G
1.
Loosen the two screws placed on the back of the
group which hold the microswitch support, C.1.067 (fig.
21)and/or the two screws which hold the microswitch to
the support.
2.
Turn the support either to the left or right, up or down so
that the microswitch activates the pump before the lever
will be half way to the extraction position (fig. 22).
3.
Tighten the screws.
