7. MAINTENANCE AND ADJUSTMENT
WARNING:
Remember that all main-
tenance operations are dangerous if
you do not
first disconnect the
power supply plug from the power
mains.
The machine parts requiring maintenance
are the following: the upright push-bearing
support (
Fig. 41
), the movable mixer sup-
port (
Fig. 39
) and the sliding chain
(
Fig. 41
).
Carry out the first maintenance job after the
first 100 hours of operation and subsequen-
tly every 500 hours.
Remove the rear panel to gain access to the
chain (
Fig. 38
) and the bearing support
(
Fig. 41
).
Use food-grade grease compliant with
USDA-H1 regulations for
the mixer sup-
port
(
Fig. 39
); (if necessary, contact your
local dealer). Use SAE MR3 type grease for
the thrust bearing support
(
Fig. 41
)
and the chain
(
Fig. 41
).
When doing a yearly check-up, lubricate the
chain (
Fig. 41
) using smaller amounts of
grease.
7.1 BELT TIGHTENING
When performing the abovementioned
maintenance or when the machine is not
working properly, (loss of rounds) check the
correct stretching of the transmission belt.
For this reason, disassemble the rear panel
from the machine and make sure that the
belt (
Fig. 38 - 40 - 42
) is tight enough.
If necessary, use the regulating system
(
Fig. 38
-
40
-
42
), by moving the
motor and therefore, tightening the belt,
without of course exaggerating.
When finished, fit the panel back.
Never use the machine with any mis-
sing, disassembled or open guards
and shields.
