Batteries (Figs. 59 and 60)
Check the battery(ies) every 250
hours
Warning
The battery contains a sulphuric acid
electrolyte which is a corrosive substance
and must be treated with great care:
1. Corrosive substance.
2. Irritating to eyes and skin.
3. Keep out of the reach of children.
4. Avoid contact with skin and eyes.
5. Wear suitable protective clothing,
gloves and eye protection.
6. In case of contact with eyes rinse
immediately with plenty of water
and seek medical attention.
7. If swallowed seek medical advice
immediately and show label.
8. When charging the battery, charge
in a well ventilated place and AL-
WAYS switch off at the mains be-
fore disconnecting the terminals.
Check the condition of the battery(ies)
ensuring that the electrolyte is up to level.
Clean the top of the battery, check that the
terminals are tight and smear them with
petroleum jelly.
Under normal use, maintenance free
batteries will not require topping up. In the
event of an alternator failure always check
the electrolyte levels. The height above the
plates should be 15 mm (5/8 in). If low,
adjust to the correct height by the addition
of distilled or de-ionised water.
In the event of an accidental discharge
it is strongly recommended that the bat-
tery is fully recharged in the workshop.
The recharge should be carried out by a
mains charger at 7 amps.
