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 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 eff ect 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.
