LITHIUM ION BATTERY AND CHARGER SAFETY FEATURES
!!
f)
Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these
instructions and in the manner intended for the particular type of power tool,
taking into account the working conditions and the work to be performed.
Use of the power tool for operations different from those intended could result in
a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified repair person using only
identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
b) If the supply cord is damaged,
it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
Over Charging Protection
This feature ensures that the battery is never overcharged. When the battery has
reached it’s full charge capacity the charger will shut off protecting the internal
components of the battery from being damaged.
Over Discharge Protection
An internal component of the battery pack is an over discharge protector. This feature
will stop the battery from discharging beyond the recommended lowest safety voltage.
Over Heat Protection
The battery has an internal Thermister cut off sensor which will cease the charging
cycle if the battery becomes hot during the charging process. This Thermister sensor
will also stop the battery from operating should the battery become too hot during
the operation of the tool. This can happen when the tool is overloaded or being used
for extended periods of time .
Up to 30min in cooling time may be required depending on ambient temperature and
operation being performed.
Over Current Protection
Should the battery be overloaded and the maximum current draw be exceeded the
battery will temporarily stop working to protect the internal components. The battery
will resume to normal operation once the excessive current draw has returned to
normal safe level. This may take a few seconds.
Short Circuit Protection
If the battery pack was to short circuit the short circuit protector would immediately
stop the battery pack from operating.
This will ensure that no further internal components of the battery or the tools are
damaged.
