Safety features incorporated with tools using
this battery pack
Product overload
These tools are fitted with an overload protection system. If
the tool is excessively forced, or the task being performed
is too great for the tool, the tool will automatically go into
an overload mode. When the tool goes into overload, the
tool will automatically and suddenly STOP. To reset the
overload, simply release the trigger. When the trigger is
pressed again, the tool will restart. Resume work after the
overload has been reset, but reduce the size of the cut or
reduce the force on the tool to make the cut.
CAUTION.
Do not continue to overload the tool and
constantly reset the overload. Doing this will cause the
battery cells to overheat.
Temperature cut out
If the tool is constantly overloaded, or the tool is used
constantly at maximum rating in high ambient conditions,
the battery cells may over heat causing the battery pack to
shut down. The tool will not re-start until the battery pack has
cooled.
If this occurs you will need to immediately stop working and
allow the battery cells to cool down.
To reduce the temperature of the cells remove the battery
pack from the tool 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 tool, 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 preset value. This feature automatically
stops the tool from operating (similar to that of the over
load condition). When this condition occurs you will need
to either insert another battery into the tool 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 tool restarting and then stopping again, after only
a few seconds of operation.
Using the line trimmer
Before starting
Before use, check that the tool is in good working
order and that the length of the trimmer line is correct, as
follows:
1. Ensure the switch is in the off position and the battery
pack is removed.
2. Examine the general condition of the tool. Inspect the
guard, switch and battery. Check for loose screws,
misalignment, binding of moving parts, improper
mounting, broken parts and any other condition that may
affect its safe operation.
If abnormal noise or vibration occurs during operation,
turn the line trimmer off immediately and have the
problem corrected.
3. Ensure that you are on a flat surface and have
secure footing.
4. Check that the line touches or goes beyond the edge
of the guard.
