Perform the operations described above as well as the following operations.
C1 - Battery electrolyte density
CHECK
- There are two types of batteries: refillable and non-refillable (sealed).
- To use batteries of the refillable type, follow the instructions below.
- Do not use or charge the battery if the level of fluid in it is below the Low mark.
Otherwise, there is the risk of damaging the elements in the battery and shortening
the battery’s service life or causing an explosion. Add distilled water immediately until
the fluid level in the battery is between the High and Low marks.
- Ensure that the level of fluid in each cell is at the bottom of the ventilation well (Fig. C1-
1): the density of the electrolyte varies according to the temperature but a minimum
level of 1270 at 16°C must be maintained.
- In the hatched area (Fig. C1-2), the battery has a normal charge level. Above this area,
the battery must be recharged. The density must not vary by 0.0025 units from one
battery element to another.
- Recharge the battery and wait 1 hour before checking the electrolyte density in each
battery element with an acidometer.
- Never check just after adding distilled water.
Manipulating and maintaining a battery can be dangerous; take the
following precautions:
- Wear protective goggles.
- Wear gloves
- Keep the battery horizontal when manipulating it.
- Never smoke or work close to a naked flame.
- Work in a sufficiently well-ventilated area.
- If any electrolyte splashes onto your skin, thoroughly rinse the area
with cold water for 15 minutes and call a doctor.
C2 - Overload sensors
CHECK
The pressure sensor (Fig. C2-1, ref 1) located on the lifting cylinder, is used to
determine the overload pressure.
The maximum height limit switch (Fig. C2-1, ref. 2), located in the middle of the chassis,
is used to put the scissors lifting coil out of service.
Lifting platforms 78 SEC 2 - 100 SEC 2:
- Set a load of 250 kg in the basket.
- Raise the basket. When the lifting platform is 1.50m from the ground, an alarm should
sound and the screen should display OVERLOAD (Fig. C2-2).
- If the alarm does not sound, please refer to the sensor settings in the repairs manual.
Lifting platform 120 SE 2:
- Set a load of 360 kg in the basket.
- Raise the basket. When the lifting platform is 1.50m from the ground, an alarm should
sound and the screen should display OVERLOAD (Fig. C2-2).
- If the alarm does not sound, please refer to the sensor settings in the repairs manual.
