4. Disconnect the charger's power cord from the
receptacle.
5. Hold the charger fi rmly and pull out the battery or
adaptor of back pack power supply.
NOTE
○ Be sure to pull out the battery from the charger after
use, and then keep it.
○ When the back pack power supply is not in use, switch
it OFF.
Regarding electric discharge in case of new
batteries or back pack power supplies, etc.
As the internal chemical substance of new batteries
or back pock power supplies and batteries or back
pack power supplies that have not been used for
an extended period is not activated, the electric
discharge might be low when using them the fi rst and
second time. This is a temporary phenomenon, and
normal time required for recharging will be restored by
recharging the batteries or back pack power supplies
2 – 3 times.
How to make the batteries and back pack power
supplies perform longer.
(1) Recharge the batteries and back pack power supplies
before they become completely exhausted.
When you feel that the power of the tool becomes
weaker, stop using the tool and recharge its battery
and back pack power supplies. If you continue to use
the tool and exhaust the electric current, the battery
and back pack power supplies may be damaged and
its life will become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery and back pack power
supplies will be hot immediately after use. If such a
battery and back pack power supplies are recharged
immediately after use, its internal chemical substance
will deteriorate, and the battery and back pack power
supplies life will be shortened. Leave the battery and
back pack power supplies for a while, and recharge
them after they have cooled.
CAUTION
○ If the battery and back pack power supplies are
charged while it is heated because it has been left
for a long time in a location subject to direct sunlight

seconds to confi rm that the battery and back pack
power supply being charged with UC36YSL is
taken out, wait for a minimum of 3 seconds before
reinserting it to continue charging. If the battery is
reinserted within 3 seconds, the battery and back

materials while charging.
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Failure to do so
could result in serious hazard.
When the charger is stained, wipe with a soft dry cloth
or a cloth moistened with soapy water. Do not use
chloric solvents, gasoline or paint thinner, for they melt
plastics.
When not in use, the charger should be stored in dry,
high or locked-up place — out of reach of children.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
