Using the drill
Trigger switch
Use the forward/reverse switch (4) to select the direction of rotation, then pull the trigger (3). This trigger switch is an electronic variable speed control which enables the user to vary the speed continuously. The speed varies according to how far the trigger switch is depressed. The further it is depressed the faster the chuck will rotate and the lighter it is depressed, the slower it will rotate.
To stop the drill, release the trigger switch.
Note. The variable Speed control fitted to this drill is NOT intended to be used for long periods of time during the operation of the task being performed. Use the variable speed to start drilling and screwing tasks, and then fully depress the trigger once the task has started.
CAUTION. Extended use of the variable speed under load will overload and then permanently damage the speed control.
Drill Overload
This drill is fitted with an overload protection. If the drill is excessively forced, or the task being performed is too great for the drill, the drill will automatically go into an overload mode. When the drill goes into overload, the drill will automatically and suddenly STOP. To reset the overload, simply release the trigger. When the trigger is pressed again, the drill will restart. Resume work after the overload has been reset, but reduce the load by using a smaller drill bit or
CAUTION. Do not continue to overload the drill and constantly reset the overload. Doing this will cause the battery cells to over heat.
Temperature Cut Out
If the drill is constantly overloaded, or the drill is used constantly at maximum rating in high ambient conditions, the battery cells may over heat causing the battery pack to shut down.
The yellow indicator on the battery pack will stay illuminated in this condition. When this occurs you will need to immediately stop drilling and allow the battery cells to reduce the temperature.
To reduce the temperature of the cells remove the battery pack from the drill and place the battery pack in a free air environment, out of direct sunlight or any other heat source.
DO NOT force cool the pack in any way. Do not place in refrigerators or freezers.
When the battery pack has cooled down it can again be used to operate the drill, as long as the load or the conditions causing the original excessive temperature has been corrected.
Low voltage cut out
The battery pack used on this tool is fitted with a low voltage cut out feature within the circuitry.
The low voltage cut out feature operates when the voltage drops below a pre set value. This feature automatically stops the drill from operating (similar to that of the over load condition). When this condition occurs you will need to either insert another battery into the drill or recharge the existing battery.
The low voltage cut out feature has been added to maximise the tools life. When this occurs, recharge the battery pack by following the battery charging section in this manual.
Note: Attempting to restart the tool without either recharging the battery or installing another battery (with charge) will lead to drill restarting and then stopping again, after only a few seconds of operation.
