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 re-sharpen the existing drill bit and reduce the amount
of force placed on the drill.
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.
