CORDLESS COMBI DRILL SAFETY
WARNINGS
Safety instructions for all operations
a) Wear ear protectors when impact drilling.
Exposure to noise can cause hearing loss.
b) Hold the power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring.
Cutting accessory contacting a "live" wire may make
exposed metal parts of the power tool "live" and could
give the operator an electric shock.
Safety instructions when using long drill bits
a) Never operate at higher speed than the maximum
speed rating of the drill bit.
At higher speeds, the bit is likely to bend if allowed to
rotate freely without contacting the workpiece, resulting
in personal injury.
b) Always start drilling at low speed and with the bit tip
in contact with the workpiece.
At higher speeds, the bit is likely to bend if allowed to
rotate freely without contacting the workpiece, resulting
in personal injury.
c) Apply pressure only in direct line with the bit and do
not apply excessive pressure.
Bits can bend causing breakage or loss of control,
resulting in personal injury.
ADDITIONAL SAFETY WARNINGS
1. Make sure that the area to be drilled is absolutely free
of any hidden obstructions including electrical wiring,
water, or gas pipes. Drilling into the aforementioned may
result in electric shock or short circuit, gas leak or other
hazards that can cause serious accidents or injuries.
2. Make sure to securely hold the tool during operation.

7. Disconnect the charger’s power cord from the
receptacle.
8. Hold the charger firmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after use,
and then keep it.
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.
CAUTION
○If the battery is charged while it is heated because
it has been left for a long time in a location subject to
direct sunlight or because the battery has just been
used, the charge indicator lamp of the charger lights for
0.3 seconds, does not light for 0.3 seconds (offfor 0.3
seconds). In such a case, first let the battery cool, then
start charging.
○When the charge indicator lamp flickers (at 0.2-second
intervals), check for and take out any foreign objects in
the charger’s battery connector. If there are no foreign
objects, it is probable that the battery or charger is
malfunctioning. Take it to your authorized Service
Center.
○Since the built-in micro computer takes about
3 seconds to confirm that the battery being charged with
UC18YSL3 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 may not be
properly charged.

(Fig. 18)
This product features functions that are designed to protect
the tool itself as well as the battery. While the switch is
pulled, if any of the safeguard functions are triggered
during operation, the LED light will blink as described in
Table 5. When any of the safeguard functions are triggered,
immediately remove your finger from the switch and follow
the instructions described under corrective action.

Safeguard Function LED Light Display Corrective Action
Overburden Protection On 0.1 second/off0.1 second If the operating with the shift knob set on
HIGH, adjust to LOW and continue operation.
Remove the cause of the overburdening.
Temperature Protection On 0.5 second/off0.5 second Allow the tool and battery to thoroughly cool.
MAINTENANCE AND INSPECTION
1. Inspecting the tool
Since use of as dull tool will degrade efficiency and
cause possible motor malfunction, sharpen or replace
the tool as soon as abrasion is noted.
2. Inspecting the mounting screws
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.
3. Maintenance of the motor
The motor unit winding is the very “heart” of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
5. Cleaning on the outside
When the power tool 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.
6. Storage
Store the power tool and the battery in a place in which
the temperature is less than 40°C and out of reach of
children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
significantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However, significantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to five times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
