4. Disconnect the charger's power cord from the
receptacle.
5. Hold the charger firmly and pull out the battery.
Regarding electric discharge in case of new batteries,
etc.
As the internal chemical substance of new batteries
and batteries that have not been used for an
extended period is not activated, the electric
discharge might be low when using them the first
and second time. This is a temporary phenomenon,
and normal time required for recharging will be
restored by recharging the batteries 2 – 3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become
completely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery.
If you continue to use the tool and exhaust the
electric current, the battery may be damaged and
its life will become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after
use. If such a battery is recharged immediately after
use, its internal chemical substance will deteriorate,
and the battery life will be shortened. Leave the
battery and recharge it after it has cooled for a
while.
CAUTIONS
If the battery has been heated (due to sunlight, etc.)
right after operation, the charger's pilot lamp may
not light in red. In such a case, first let the battery
cool, then start charging.
When the pilot lamp flickers in red (at 0.2 – second
intervals), check for and take out any foreign objects
in the charger's battery installation hole. If there are
no foreign objects, it is probable that the battery
or charger is malfunctioning. Take it to your
authorized Service Center.
Do not use UC24YF to charge the battery at a
temperature lower than 0°C. Rapid charging at low

PRIOR TO OPERATION

1. Setting up and checking the work environment
Check that the working environment is suitable by
following the precautions.
2. Prepare a wooden work bench (Fig. 3)
Since the saw blade will extend beyond the lower
surface of the lumber, place the lumber on a work
bench when cutting. If a square block is utilized as
a work bench, select level ground to ensure it is
properly stabilized. An unstable work bench will
result in hazardous operation.
CAUTION:
To avoid possible accident, always ensure that the
portion of lumber remaining after cutting is securely
anchored or held in position.
