Battery maintenance
Battery connector
In addition to the automatic main switch, also
disconnect the battery if the loader will not be used
for a longer period of time, or when servicing the
machine. The battery pack can be disconnected
manually from the loader by disconnecting the main
battery cable.
Pull the connectors apart from each other fully
disconnect battery. Disconnect battery in at least the
following cases:
before you do any maintenance that requires
access near electric motors or other main electric
parts
before maintenance of any electric component
before you disconnect any electric cable
there is a risk of fire
when loader is being transported
there is visible mechanical damage on battery
you plan to store the loader for long storage
period.
1. Recharge daily
Recharge battery after each time loader is used. Also
partially drained battery must be recharged. This
ensures maximum life of the battery.
Check battery water level after each charge cycle
and add water if necessary. See page See page 63
for charge and water instructions.
2. Refill battery water level
After each charge cycle, check the level of electrolyte
in battery cells from the float caps. Add battery water
as described in page See page 63.
3. Ensure full charge
To balance the charge between all individual battery
cells, do a full charge at least weekly. Allow the
charger to be plugged in until the green indicator light
is lit. The balancing charge is made at the end of
charge cycle. It is recommended to do the full charge
as often as possible.
4. Cleaning of battery
The battery should always be kept clean and dry to
prevent so called leakage currents between battery
cells. Any dirt or liquid on the battery can cause
current to flow between battery cells. This will cause
discharge of individual cells and poor overall
performance of the battery pack.
Any liquid on the battery or in the battery tray must
be considered as acid and necessary precautions
must be taken. Wear safety gloves that protect from
contact with acids. Use preferably a suction system
to remove any liquid on battery. Dispose materials
use for cleaning in appropriate manner.
During battery recharge, small quantities of
electrolyte particles escape and form a weakly
conductive layer on the cell covers. Leakage current
flows through this layer then, leading to increased
and varying self-discharging. If suspecting that
battery capacity is weakened after weekend storage,
this dirt can be the cause.
Risk of sparks, fire, and
explosion - Dirt on battery can
cause current to flow between
battery cells. Dirty battery can
cause short-circuit of battery cells
and sparks. This can be a source
of ignition for gases produced
during charge. Clean the top of the
battery before recharge. Never
clean during recharge to avoid
sparks caused by static electricity.
Risk of battery damage and acid
spill - Never use pressure
washer to clean the battery.
Pressure washer can damage the
battery cells or the caps on top of
the battery, allowing water to enter
battery. This will result in battery
damage, and can also cause
battery electrolyte (acid) to spill
from battery. Clean battery as
instructed in this manual.
