Drill safety features

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 overload

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 tool's 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 the drill restarting and then stopping again after only

a few seconds of operation.
