How to Guide

GB
Intended Use
• Battery operated impact driver suitable for medium duty tasks driving nuts
and bolts
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 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 and battery
charger checked by an electrician or a power tool technician
Charging the battery
1. Depress the Battery Release Button (4) and remove the battery from the
tool
2. Insert the battery into the T20 Battery Charger (8). Do not use excessive
force when inserting the battery. 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 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. 2.0Ah battery: Please note the full
charging time will be approximately 30 minutes
• Normal battery charging time is approximately 1hour for a recently fully
discharged 4Ah battery at normal temperature. Charging times will vary
outside these conditions
• 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 (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
