Insert the battery so that it is
properly seated in the charger.
Use a cotton swab or other tool to

Allow the battery to properly cool

When a storage battery with little
power left is not used for an
extended period of time, battery
power may drop so low that it
cannot turn on the battery level
warning lamp. Charge the battery.
Remove the storage battery from the
battery compartment in the tool and
check for foreign matter. Also check
the battery electrodes for soiling.
Make sure that the battery is pressed
in until it clicks into place.
If the blade does not move but the
motor is turning, the blade has
probably been incorrectly installed.
Make sure that the crank holder and
crank cam has been installed.
When there is foreign matter in the
blade, remove the battery and use
a pair of tongs or similar tool to
remove it.
Take great care since the tool may
start operating when the foreign
matter has been removed.
Sap or rust may also prevent the
blade from operating. Use a wire
brush or similar tool to remove sap
or rust.
This is the effect of a function that
protects the battery by turning off
the motor when the tool is exposed
to an excessive load. Release the
switch and remove what caused
the excessive load and pull back
the switch to resume work.
To prevent accidents from
incorrect operation, the Lock Off
switch must be pressed while the
switch is pulled back to start the
motor.
