Warning! Not to enter the space beneath a raised work platform and extending structure
during maintenance unless the chock is in place.
Note: When the work platform of a MEWP needs to
be raised for routine servicing purposes, a captive
chock shall be used to enable the extending structure
to be held in the required position to prevent work
platform from falling down unexpectedly.
8.1 Battery charging
Chapter 8 Battery
8.1.1 Turn the key and switch on, when the display indicated voltage is below 11 volt,
please charge up the battery.
8.1.2 The rated specification of the battery charger supplied:
Input: 220V AC50/60Hz
Output: 12V DC 15A
8.1.3 When start charging, insert the output plug of the charger to the charging socket
of the chassis first, then the input plug of the charger to the socket of AC power supply.
Turn on the charger switch; battery charging is started with indicator (red lamp) lights
up. Normal recharging lasts about 10 hours. When charging is terminated check that
all cells have reached a density between
1.260~1.280kg/l at 30°C.
When charge is finished, the AC supply should be cut off.
8.1.4 Battery charging should be done in a well-ventilated place and there are no
naked flames, no sparks and no heat radiation sources nearby.
8.1.5 Make sure the level of the electrolyte is above the lower line. If the elements
are not covered, top up with distilled water. Under normal conditions topping up can be
generally done once a month.
8.2 Battery maintenance
The acid level must be checked at least once a week. Refilling must not take place until
charging has been finished, as the acid expands during charging.
Only distilled water can be used for refilling. The battery surface must be kept clean
and dry, as dirt and wet will cause leakage of current and consequently reduced battery
capacity, Acid spill can be neutralized with soda solution or diluted ammonia, which is
to be washed off with water.
The terminal connections must be firmly tightened and greased with acid-free grease,
which prevents sulphate formations. Sulphate coating reduces the contact surface,
resulting in a considerable voltage
