is not less than 30 to 45 minutes.
When charging a battery that has been discharged during
heavy use allow the battery to cool down before charging. It is
recommended that the cooling down period is not less than 30
to 45 minutes.
NiCad charging & chargers
NiCad batteries need to be recharged with a reasonable amount
of care, largely because they can be damaged by overcharging.
Overcharging can result in the battery temperature and internal
pressure to rise rapidly. This can cause the cells to distort
and lose electrolyte, and in extreme cases where the internal
pressure is extremely high they can even explode.
This situation can also arise when an overcharged battery is
fitted to the product and is being used.
In order to avoid this extreme situation it is of vital importance
that NiCad batteries are fully discharged before charging and
that the charge time is not exceeded except when “Conditioning”
a new battery. Repeated charging of partially discharged
batteries could cause failure of one or more of the cells.
Self discharge
A NiCad battery can self discharge and lose its stored charge due
to internal chemical action. Typically it can lose approximately
10% of its charge in the first 24 hours after fully charging, and
then loses it by a further 10% per month.
Battery Charging Indoors
This charger is designed to be used indoors. We do not
recommend that it is used inside your home. Ideally batteries
should be charged on a bench in a workshop, garage or shed.
If the charging operation is to be carried out in your home the
area must be well ventilated and the charger must be placed
on a non combustible surface ensuring that the ventilation slots
are not blocked. Never exceed the charging time except when
“Conditioning” a new battery, as this could damage the battery
and charger.
Battery disposal
When the battery fails to charge or maintain its charge, its
usable life is exhausted. To preserve natural resources, please
recycle or dispose of the battery pack properly. This battery
pack contains nickel-cadmium cells. Before disposal ensure that
the battery pack is fully discharged by operating your cordless
product then remove the battery pack from the drill housing and
cover the battery pack connections with heavy duty tape, to
prevent short circuit and energy discharge which could result in
a fire. Do not attempt to open or remove any of the components.
Consult your local waste authority for information regarding
available recycling and / or disposal options.
SPECIFIC SAFETY INSTRUCTIONS
Re-chargeable batteries.
Batteries may leak or explode if not charged or handled
correctly. Always observe the following precautions when
handling batteries.

Do not short out, or attempt to dismantle the battery.
Do not expose the battery to flames or excessive heat.
Do not immerse in or expose the battery to water.
Do not store or transport the battery with loose metal objects
such drill and driver bits.
Batteries are prone to leakage when discharged. To avoid
damage to the product, remove or re-charge the battery when
no charge remains.
Store the battery in a cool place when not in use.
After prolonged use the battery may become hot. Before
removing the battery, switch the machine off and allow the
battery to cool down.
Do not use the battery if you notice any discoloration or distortion
of the battery casing.
CHARGING THE BATTERY
Note: During charging the battery will become warm as it is
being charged.
The battery supplied with this power tool contains a test charge
only and must be fully charged before use.
First read the safety instructions then follow the charging
instructions.
1. Connect the charger transformer lead into the charger
base.
2. Plug the charger into a standard 230V~50Hz mains socket
outlet.
3. Do not allow the cable to become knotted or kinked.
4. This charger and battery pack are specifically designed to
work together. DO NOT attempt to charge any other brand
of cordless tool or battery pack with this charger.
5. Note the battery has a keyway which allows it to fit into the
charger only one way.
6. Place the battery pack into the charger base.
7. Time the charge for 3 (5-7) hours only.
8. Unplug the charger when not in use and store it in a suitable
storage cabinet.
9. Avoid charging your battery in freezing conditions as
charging power will not be sufficient.
10. When charging more than one battery pack in succession
allow at least 30 minutes for the charger to cool down before
charging the additional battery.
Always remove the battery pack and store it safely when the
cordless drill is not in use.
ADDITIONAL OR REPLACEMENT BATTERIES
Additional or replacement batteries specifically designed to
work with this drill and charger are available from your service
centre.
