SAFETY
GENERAL SAFETY RULES – FOR ALL BATTERY OPERATED TOOLS
WARNING: Read and understand all instructions.
Failure to follow all instructions listed below, may result in electric shock,
fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
1. Work Area
(1) Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
(2) Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power tools create sparks which may ignite the
dust of fumes.
(3) Keep bystanders children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
2. Electrical Safety
(1) A battery operated tool with integral batteries or a separate battery pack must be
recharged only with the specified charger for the battery.
A charger that may be suitable for one type of battery may create a risk of fire when
used with another battery.
(2) Use battery operated tool only with specifically designed battery pack.
Use of any other batteries may create a risk of fire.
3. Personal Safety
(1) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use tool while tired or under the influence of drugs, alcohol, or
medication. A moment of inattention while operating power tools may result in
serious personal injury.
(2) Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your
hair, clothing and gloves away from moving parts. Loose clothes, jewelry, or long hair
can be caught in moving parts.
(3) Avoid accidental starting. Be sure switch is off position before inserting battery.
Carrying tools with your finger on the switch or inserting the battery pack into a tool
with the switch on invites accidents.
(4) Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that
is left attached to a rotating part of the tool may result in personal injury.
(5) Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enable better control of the tool in unexpected situations.
(6) Use safety equipment. Always wear eye protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must be used for appropriate conditions.
4. Tool Use and Care
(1) Use clamps or other practical way to secure and support the workpiece to a stable
platform. Holding the work by hand or against your body is unstable and may lead to
loss of control.
English
5
(2) Do not force tool. Use the correct tool for your application. The correct tool will do
the job better and safer at the rate for which it is designed.
(3) Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled
with the switch is dangerous and must be repaired.
(4) Disconnect battery pack from tool or place the switch in the locked or off position
before making any adjustments, changing accessories, or storing the tools. Such
preventive safety measures reduce the risk of starting the tool accidentally.
(5) Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
(6) When battery pack is not in use, keep it away from other metal objects like: paper
clips, coins, keys, nails, screws, or other small metal objects that can make a
connection from one terminal to another.
Shorting the battery terminals together may cause sparks, burns, or a fire.
(7) Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained
tools, with sharp cutting edges are less likely to bind and are easier to control.
(8) Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the tools operation. If damaged, have the tool serviced
before using. Many accidents are caused by poorly maintained tools.
(9) Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool, may become hazardous when used on
another tool.
5. Service
(1) Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
(2) When servicing a tool, use only identical replacement parts. Follow instructions in
the Maintenance section of this manual. Use of unauthorized parts or failure to follow
Maintenance Instruction may create a risk of electric shock or injury.
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities contains chemicals known to the State of California to cause cancer, birth defects
or other reproductive harm. Some examples of these chemicals are:
● Lead from lead-based paints,
● Crystalline silica from bricks and cement and other masonry products, and
● Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work.
To reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to filter
out microscopic particles.

(2) Regarding the temperature of the rechargeable battery.
The temperatures for rechargeable batteries are as shown in the table below, and
batteries that have become hot should be cooled for a while before being recharged.
(3) Regarding recharging time (At 68°F (20°C))
In approx. 60 minutes.
NOTE: The charging time may vary according to temperature and power source voltage.
4. Disconnect battery charger from the receptacle.
CAUTION:
Do not pull the plug out of the receptacle by pulling on the cord.
Make sure to grasp the plug when removing from receptacle to avoid damaging cord.
5. Remove the battery from the battery charger.
Supporting the battery charger with hand, pull out the battery from the battery charger.
CAUTION:
● When the battery charger has been continuosly used, the battery charger will be heated,
thus constituting the cause of the failures. Once the charging has been completed, give
15 minutes rest until the next charging.
● If the battery is rechraged when it is warm due to battery use or exposure to sunlight,
the pilot lamp may light in green.
The battery will not be recharged. In such a case, let the battery cool before charging.
● When the pilot lamp blinks rapidly 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.
● Since the built-in micro computer takes about 3 seconds to confirm that the battery
being charged with UC 14YF2 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.
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.
BEFORE USE
Check the work area to make sure that it is clear of debris and clutter.
Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.

(1) When using this unit as a screwdriver, line up the one
of the numbers “1 – 5” on the cap, or the white dot,
with the triangle mark on the outer body.
(2) When using this unit as a drill, line up the cap drill mark
“
” with the triangle mark on the outer body.
(3) When using this unit as a hammer drill, line up the cap
hammer mark “
” with the triangle mark on the
outer body.
CAUTION:
䢇 The cap cannot be set between the numerals “1 – 5”.
䢇 Do not use with the cap drill mark and the point at the
middle of the hammer mark. Doing so may cause
damage.
䢇 To make holes in the metal, wood or plastic, switch
to “Rotation (Rotation only)”, and holes in bricks or
concrete blocks, switch to “Impact (Impact + Rota-
tion)”. If an operation which is normally performed at
the “Rotation” setting is performed at “Impact” set-
ting. the effect of marking holes does not only in-
crease but it may also damage the bit or other parts.
6. Tightening torque adjustment
(1) Tightening torque
Tightening torque should correspond in its intensity to the screw diameter. When too
strong power is used, the screw head may be broken or be injured.
Be sure to adjust the cap position according to the screw diameter.
(2) Tightening torque indication (See Fig. 9)
The tightening torque differs depending on the type of screw and the material being
tightened.
The unit indicates the tightening torque with the numbers “1 – 5” on the cap. The
tightening torque at position “1” is the weakest and the torque is strongest at the highest
number.
(3) Adjusting the tightening torque (See Fig. 9)
Rotate the cap and line up the numbers “1 – 5” on the cap, with the triangle mark on the
outer body. Adjust the cap in the weak or the strong torque direction according to the
torque you need.
CAUTION:
䢇 The motor rotation may be locked to cease while the unit is used as drill. While operating
the hammer drill, take care not to lock the motor.
䢇 When setting the shift knob to “HIGH” (high speed) and the position of the cap is “4”
or “5”, it may happen that the clutch does not engaged and that the motor is locked. In
such a case, please set the shift knob to “LOW” (low speed).

䢇 If the motor is locked, immediately turn the power off. If the motor is locked for a while,
the motor or battery may be burnt.
䢇 Too long hammering may cause the screw broken due to excessive tightening.
䢇 A buzzing noise is produced when the motor is about to rotate; This is only a noise, not
a machine failure.
7. For drilling into brick
CAUTION:
䢇 When drilling brick continuously, the number of holes to be drilled should be less than
specified in Table 4.
䢇 When the hammer drill is used continuously, the body may be heated if this happens,
leave the hammer drill to cool.
䢇 If the hammer drill is used continuously to drill more holes than specified in Table 4, the
motor will be burnt.
䢇 Excessive pressing force never increases drilling speed. It will not only damage the drill
tip or reduce working efficiency, but could also shorten the service life of drill bit.
Operate the hammer drill within 10-25 kg pressing force while drilling into brick.
