Remedy
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.
Use a wire brush or other tool to
remove sap and rust and use a fi le
or whetstone to sharpen the blade.
If these eff orts fail to make the blade
sharper, the blade has reached the end
of its service life. Replace the blade
with a new one.
Some garden trees have wood that
is very hard and may be beyond the
capacity of the tool even if it is of a
width that is within normal capacity.
Use a pair of pruning shear to remove
thick branches before starting work.
An oblique cut may also exceed the
capacity of the tool since the length of
the cut increases. Be sure to trim thick
branches at right angles.
