Intended Use
• Battery operated drill with screwdriver, drill and hammer drill functions suitable for
medium duty drilling and driving tasks
Unpacking Your Tool
• Carefully unpack and inspect your tool. Fully familiarise yourself with all its features and
functions
• Ensure that all parts of the tool are present and in good condition. If any parts are missing
or damaged, have such parts replaced before attempting to use this tool
Before Use
• This cordless impact driver has been shipped in a low charge condition. Charge the
battery before use
Battery charger operation
• The charger and battery pack may become warm while charging. This is normal and does
not indicate a problem
• Use the charger at normal room temperatures whenever possible. To prevent overheating,
do not cover the charger and do not charge the battery in direct sunlight or near sources
of heat
If the battery does not charge properly:
• Check current at power outlet by plugging in a lamp or other appliance
• If charging problems persist, have the impact driver, battery pack and battery charger
checked by an electrician or a power tool technician
Charging the battery pack
1. Depress the Battery Release Button (7) and remove the battery from the tool
2. Insert the battery pack into the T20 Battery Charger (11). Do not use excessive force
when inserting the battery pack. If it does not slide into place easily, it is not being
inserted correctly
3. Initially only the green LED may flash as it evaluates the status of the battery. When
charging the red LED will illuminate and the green LED will be OFF
4. When the battery is fully charged the red LED will be OFF and the green LED will
illuminate
5. The battery charger will constantly monitor the condition of the battery when charging
6. Remove the battery pack as soon as possible when completely charged
7. Disconnect the charger from the power supply and store in a clean, dry environment out of
the reach of children
• Normal battery charging time is approximately 1hour for a recently fully discharged 4Ah
battery at normal temperature. Charging times will vary outside these conditions. 2.0Ah
battery: Please note the full charging time will be approximately 30 minutes
• You do not need to fully discharge the battery before recharging but you should not
attempt to recharge a battery that is already fully charged
• You can interrupt charging at any point to use the battery. Under normal conditions the
charger charges at a higher rate but reduces the charging rate as the battery becomes
fully charged. An 80% charge is achieved after 1/2hr of charging

Note
: If the lights on the battery charger fail to illuminate according to the chart above or
indicate a fault condition:
• Check the battery is firmly seated in the battery charger
• Check all connections and that mains power is switched on
Initial charge
• The initial charge will vary depending on the existing charge in the battery. Allow the
battery to reach full charge as indicated on the charger
• After discharging, recharge the battery completely, as indicated by the LED on the battery
charger, for the next 4 to 5 uses. This will ensure that the battery is performing to its
highest capacity
• Subsequent full charges will take approximately 1 hour (T20HCB: 4Ah battery), however
the battery can be recharged when the battery is only partially discharged
Re-charging the battery
• After use, a lithium-ion battery must be allowed to cool down before charging
• If a hot battery is inserted into the charger both LEDs will illuminate. The charger will
begin to charge when the battery has cooled sufficiently (this may take several minutes)
Installing the battery
• The battery should fit easily into the battery charger or drill unit. If the battery is difficult
to fit, check the condition of the battery and contacts
Battery - length of service
• The length of service from each charging cycle will depend on the type of workload. The
battery charger and battery for this impact driver have been designed to provide a long
trouble-free working life. The charger intelligently monitors the condition of the battery
and selects the ideal charging rate for the condition of the battery. It protects the battery
from over-charging or charging at too high a rate. However, like all batteries, performance
will be reduced over time
To maximise battery life:
• Store and charge the battery in a cool area. Temperatures above or below normal room
temperature will reduce battery life
• Never store lithium-ion batteries in a discharged condition. Recharge them immediately
after they are discharged. For storing long term, store fully charged
• All batteries gradually lose their charge, even lithium-ion batteries, but the discharge rate
is very low. If the impact driver is stored for long periods of time without use, recharge
the battery every three to four months and disconnect the battery from the power tool
before it is stored. This practice will prevent the lithium-ion battery being damaged when
stored
