injury, or may cause machine damage.
NOTE emphasizes essential information.
SAFETY
GENERAL POWER TOOL SAFETY WARNINGS
WARNING:
Read all safety warnings and instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated
(cordless) power tool.
1)Work area safety
a)Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
b)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.
c)Keep children and bystanders away while
operating a power tool.
Distractions can cause you to lose control.
2)Electrical safety
a)Power tool plugs must match the outlet.
Never modify the plug in any way.
Do not use any adapter plugs with earthed
(grounded) power tools.
Unmodified plugs and matching outlets will
reduce risk of electric shock.
b)Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators.
There is an increased risk of electric shock if
your body is earthed or grounded.
c)Do not expose power tools to rain or wet
conditions.
Water entering a power tool will increase the
risk of electric shock.
d)Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges
or moving parts.
Damaged or entangled cords increase the risk
of electric shock.
e)When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
f)If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply.
Use of an RCD reduces the risk of electric shock.
3)Personal safety
a)Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired
or under the influence of drugs, alcohol or
medication.
3
English
A moment of inattention while operating
power tools may result in serious personal
injury.
b)Use personal protective equipment. Always
wear eye protection.
Protective equipment such as dust mask, nonskid safety shoes, hard hat, or hearing
protection used for appropriate conditions
will reduce personal injuries.
c)Prevent unintentional starting. Ensure the
switch is in the off-position before connecting
to power source and/or battery pack, picking
up or carrying the tool.
Carrying power tools with your finger on the
switch or energising power tools that have
the switch on invites accidents.
d)Remove any adjusting key or wrench before
turning the power tool on.
A wrench or a key left attached to a rotating
part of the power tool may result in personal
injury.
e)Do not overreach. Keep proper footing and
balance at all times.
This enables better control of the power tool
in unexpected situations.
f)Dress properly. Do not wear loose clothing
or jewellery. Keep your hair, clothing and
gloves away from moving parts.
Loose clothes, jewellery or long hair can be
caught in moving parts.
g)If devices are provided for the connection of
dust extraction and collection facilities,
ensure these are connected and properly
used.
Use of dust collection can reduce dust-related
hazards.
4)Power tool use and care
a)Do not force the power tool. Use the correct
power tool for your application.
The correct power tool will do the job better
and safer at the rate for which it was designed.
b)Do not use the power tool if the switch does
not turn it on and off.
Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
c)Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools.
Such preventive safety measures reduce the
risk of starting the power tool accidentally.
d)Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e)Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation.
If damaged, have the power tool repaired
before use.
Many accidents are caused by poorly
maintained power tools.
f)Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
g)Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed.
Use of the power tool for operations different
from those intended could result in a
hazardous situation.
5)Battery tool use and care
a)Recharge only with the charger specified by
the manufacturer.
A charger that is suitable for one type of
battery pack may create a risk of fire when
used with another battery pack.
b)Use power tools only with specifically
designated battery packs.
Use of any other battery packs may create a
risk of injury and fire.
c)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 burns or a fire.
d)Under abusive conditions, liquid may be
ejected from the battery; avoid contact. If
contact accidentally occurs, flush with water.
If liquid contacts eyes, additionally seek
medical help.
Liquid ejected from the battery may cause
irritation or burns.
6)Service
a)Have your power tool serviced by a qualified
repair person using only identical
replacement parts.
This will ensure that the safety of the power
tool is maintained.

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
●
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 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 pilot lamp of the charger lights for
1 second, does not light for 0.5 seconds (off for
0.5 seconds). In such a case, first let the battery
cool, then start charging.
●
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC18YGSL 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.

it.
Push the impact driver just enough to keep the bit
fitting the head of the screw.
CAUTION:
Applying the impact driver for too long tightens the
●
screw too much and can break it.
●
Tightening a screw with the impact driver at an
angle to that screw can damage the head of the
screw and the proper force will not be transmitted
to the screw.
Tighten with this impact driver lined up straight
with the screw.
7. Tightening and loosening bolts
A hex. socket matching the bolt or nut must first be
selected. Then mount the socket on the anvil, and
grip the nut to be tightened with the hex. socket.
Holding the wrench in line with the bolt, press the
power switch to impact the nut for several seconds.
If the nut is only loosely fitted to the bolt, the bolt
may turn with the nut, therefore mistaking proper
tightening. In this case, stop impact on the nut and
hold the bolt head with a wrench before restarting

After use for continuous bolt-tightening work, rest
the unit for 15 minutes or so when replacing the
battery. The temperature of the motor, switch, etc.
will rise if the work is started again immediately after
battery replacement, eventually resulting in burnout.
CAUTION:
Do not touch the metal parts, as it gets very hot
during continuous work.
This switch has a built-in, electronic circuit which
steplessly varies the rotation speed. Consequently,
when the switch trigger is pulled only slightly (low
speed rotation) and the motor is stopped while
continuously driving in screws, the components of
the electronic circuit parts may overheat and be
damaged.
The appropriate torque for a screw differs according
to the material and size of the screw, and the material
being screwed etc., so please use a tightening time
suitable for the screw. In particular, if a long
tightening time is used in the case of screws smaller
than 5/16” (8 mm), there is a danger of the screw
breaking, so please confirm the tightening time and
the tightening torque beforehand.
under impact
The optimum tightening torque for nuts or bolts
differs with material and size of the nuts or bolts.
An excessively large tightening torque for a small
bolt may stretch or break the bolt. The tightening
torque increases in proportionate to the operation
time. Use the correct operating time for the bolt.
The following factors contribute to a reduction of
the tightening torque. So confirm the actual
tightening torque needed by screwing up some bolts
before the job with a hand torque wrench. Factors
affecting the tightening torque are as follows.
When the discharge margin is reached, voltage
decreases and tightening torque is lowered.
The tightening torque increases when the operating
time increases. But the tightening torque does not
increase above a certain value even if the tool is
driven for a long time.
The tightening torque differs with the diameter of
the bolt. Generally a larger diameter bolt requires
larger tightening torque.
(4) Tightening conditions
The tightening torque differs according to the torque
ratio, class, and length of bolts even when bolts with
the same size threads are used. The tightening
torque also differs according to the condition of the
surface of workpiece through which the bolts are to
be tightened. When the bolt and nut turn together,
torque is greatly reduced.
MAINTENANCE AND INSPECTION
English
CAUTION:
1. Checking the condition of the bit
The bits should be checked regularly. If worn or
broken bits can slip or decrease the efficiency of the
motor and burn it out.
Replace worn bits with new ones.
CAUTION:
If you use a driver bit of which point is worn or
broken, it will be dangerous since it slips. So
replace it with a new one.
2. Check the Screws
Loose screws are dangerous. Regularly inspect them
and make sure they are tight.
CAUTION:
Using this power tool with loosened, screws is
extremely dangerous.
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. Check for Dust
Dust may be removed with a soft cloth or a cloth
dampened with soapy water.
Do not use bleach, chlorine, gasoline or thinner, for
they may damage the plastics.
