SECTION 8 - CONTROL COMPONENTS
Battery Cleaning:
• Regularly clean and dry battery top.
• Ensure all connections are clean and correctly tight.
• Coat terminals with a silicone dielectric compound.
• Drain the water that can accumulate at the bottom of
the batteries container using a bulb as follow:
T8E/T20E
T10E/T26E
Figure 8-4. Draining the water
Filling Circuit Inspection and Servicing:
Battery filling circuit must be serviced once a year. Clean-
ing frequency must be increased in case of premature
clogging of the filter or a reduction of water flow.
• Disconnect and clean the filter (5) (See Figure 8-2) by
reversing the water flow from the normal direction.
• Check hoses for flexibility. In case of hardening in the
connections area, replace the hose.
• Check every fittings and connections for leakage.
• Check the caps individually. Ensure perfect mobility of
the floats. In case of clogging, replace the cap.
• In any case, it is recommended to replace the caps
every 2 or 3 years.
NOTE: The filling circuit includes a check valve that pre-
vents remaining water in the can from flowing in bat-
tery cells by gravity. Never remove this check valve.
Doing so will cause excessive electrolyte level in the
cells and electrolyte overflow.

Battery Container Maintenance:
Keep the metallic container clean. In case of corrosion,
clean, neutralize corrosion and apply anti-acid paint on
the affected area.
Battery Voltage and Electrolyte Specific Gravity
Recording:
NOTE: Voltage and specific gravity measures should not be
performed after battery cells have been filled. These
measures must be done after a complete charge,
once the charger has been unplugged and after the
battery has been standing for at least 15 minutes.
Figure 8-5. Measuring Electrolyte Specific Gravity
• Open the filling cap of the cell where the red cable is
connected (B+).
• Using an hydrometer, take a quantity of electrolyte suf-
ficient so that the float emerges. Ensure that the float
top does not touch the rubber bulb or that the float
does not stick by capillarity to the glass wall.
• Read the value as indicated in the previous figure.
• Return electrolyte in the cell and record the value in the
battery service log.
• Measure the cell voltage and record the value in the
battery service log.
• Repeat operation for each cell in sequence from B+
(Red cable) to B- (Black cable).
Use of a Battery in a Cold Chamber or in a Cold Cli-
mate:
Low temperatures decrease battery capacity. The battery
must be fully charged when the machine is operated in a
cold chamber or in cold weather condition.
Battery Not Working Continuously or Inactive Battery:
A battery that is not used or used intermittently must be
stored charged in a dry area away from freezing tempera-
tures. A charge must be performed once a month.
• Disconnect the battery to insulate it electrically.
• Keep the top of the battery clean and dry to prevent
self-discharge.
