PRODUCT SAFETY
GENERAL POWER TOOL
SAFETY WARNINGS
WARNING Read all safety warnings,
instructions, illustrations and
specifications provided with this power tool.
Failure to follow all instructions listed below 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 or
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. 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, non-skid 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 and clothing
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.
h) Do not let familiarity gained from
frequent use of tools allow you to become
complacent and ignore tool safety
principles. A careless action can cause severe
injury within a fraction of a second.
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 remove the battery pack,
if detachable, 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

4

KUC35 KUC35.9 KUC35.91
untrained users.
e) Maintain power tools and accessories.
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.
h) Keep handles and grasping surfaces
dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do not
allow for safe handling and control of the tool in
unexpected situations.
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.
e) Do not use a battery pack or tool that is
damaged or modified. Damaged or modified
batteries may exhibit unpredictable behaviour
resulting in fire, explosion or risk of injury.
f) Do not expose a battery pack or tool to fire
or excessive temperature. Exposure to fire or
temperature above 130 °C may cause explosion.
g) Follow all charging instructions and
do not charge the battery pack or tool
outside the temperature range specified
in the instructions. Charging improperly or
at temperatures outside the specified range may
damage the battery and increase the risk of fire.
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.
b) Never service damaged battery packs.
Service of battery packs should only be performed
by the manufacturer or authorized service
providers.
DRILL SAFETY
WARNINGS
1) Safety instructions for all operations
a) Hold the power tool by insulated gripping
surfaces, when performing an operation
where the cutting accessory or fasteners
may contact hidden wiring or its own cord.
Cutting accessory or fasteners contacting a "live"
wire may make exposed metal parts of the power
tool "live" and could give the operator an electric
shock.
2) 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.
SAFETY WARNINGS FOR
BATTERY PACK
a) Do not dismantle, open or shred cells or
battery pack.
b) Do not short-circuit a battery pack. Do
not store battery packs haphazardly in
a box or drawer where they may short-
circuit each other or be short-circuited by
conductive materials. 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.
c) Do not expose battery pack to heat or fire.
Avoid storage in direct sunlight.
d) Do not subject battery pack to mechanical
shock.

LED light indicator
Before operation, the LED light
will be activated when the On/Off
switch is slightly pressed, and will
automatically turn off 20 seconds
after the On/Off switch is released.
The tool and battery are equipped
with a protection system. When
the LED Light is quickly ashing 3
seconds and turn off, the system will
automatically cut off power to the tool
to extend battery life. The tool will
automatically stop during operation
if the tool and/or battery are placed
under one of the following conditions:
• Overloaded: The tool is
operated in a manner that causes
it to draw an abnormally high
current. In this situation, release
the Trigger Switch on the tool and
stop the application that caused
the tool to become overloaded.
Then pull the Trigger Switch again
to restart.
• Overheated: Under the
condition above, if the tool does
not start, the Tool and Battery are
overheated. In this situation, let
the Tool and Battery cool before
pulling the Trigger Switch again.
• Low battery voltage: The
remaining Battery capacity is too
low and the tool will not operate.
In this situation, remove and
recharge the Battery.
Warning: To turn on the light,
press the On/Off switch and
make sure the Forward/Reverse
Rotation Control is on right/left
position.
ASSEMBLY
Note: Always power off the tool and remove the
battery pack before performing any assembly
operations on the tool.
Be sure to use the side handle (auxiliary
handle) for safe operations.
1. Install the side handle (auxiliary handle) (see
fig. G)
Firstly, rotate the handle counterclockwise relative to the
outer jaw ①to separate the jaws ②, then hold the outer
jaw ①, stick the jaws ②in the grooves ③on the left and
right sides of the reducer, hold the outer jaw ①with one
hand, and rotate the handle clockwise relative to the outer
jaw ①to tighten it until the jaws ①②are xed with the
grooves ③ tightly.
2. Remove the side handle (auxiliary handle)
(see fig. H)
Place the tool on the workbench, hold the outer jaw ①
with one hand, rotate the handle counterclockwise rela-
tive to the outer jaw ①until the jaws ②are loose, and
then remove them from the reducer grooves ③.
ANTI-SPRAIN FUNCTION
The power tool will shut down quickly, when drill body
suddenly rotates around the bit due to blockage dur-
ing drilling. When the quick shutdown function is in
effect, the LED light will rst ash twice slowly and then
ash every 1.5s circularly. Once the On/Off Switch is
released, the LED light stops ashing.
Press the On/Off Switch again to restart the tool.
PROBLEM SOLUTION
1. WHY DOES THE DRILL NOT TURN ON WHEN
YOU PRESS THE SWITCH?
The Forward and Reverse Switch, which is on top of
the trigger, is positioned in the lock function. Unlock the
Forward and Reverse Switch putting it into the required
rotation position. Push the trigger and the drill will start
to rotate.
2. THE DRILL STOPS BEFORE THE SCREW IS
COMPLETELY TIGHTENED. WHY?
Verify the torque position of the Torque Adjustment
Ring, you can nd the Torque Adjustment Ring between
the Chuck and the drill body. Position 1 is the lowest
torque (screw driving force) and position 20 is the
highest torque (screw driving force). Position is for
drill operation. Position is for hammer drill operation.
Regulate the Torque Adjustment Ring to a higher
position to reach the best result.
3. I CAN NOT FIT THE BATTERY INTO THE
BATTERY CHARGER. WHY?
The battery can be inserted into the charger only in one
direction. Turn the battery around until it can be inserted
into the slot, the red LED Light should turn on when the
battery is charging.
4. REASONS FOR DIFFERENT BATTERY PACK
WORKING TIMES
Charging time problems, as above, and having not used
a Battery Pack for a prolonged time will reduce the
Battery Pack working time. This can be corrected after

13
Lithium-Ion brushless hammer drill
KUC35 KUC35.9 KUC35.91
several charge and discharge operations by charging &
working with your drill. Heavy working conditions such
as large screws into hard wood will use up the Battery
Pack energy faster than lighter working conditions. Do
not re-charge your Battery Pack below 0oC and above
40oC as this will affect performance.
MAINTENANCE
Remove the battery pack from the tool before
carrying out any adjustment, servicing or
maintenance.
There are no user serviceable parts in your power
tool. Never use water or chemical cleaners to clean
your power tool. Wipe clean with a dry cloth. Always
store your power tool in a dry place. Keep the motor
ventilation slots clean. Keep all working controls free
of dust.
FOR BATTERY TOOLS
The ambient temperature range for tool and battery use
and storage is 0oC -45oC.
The recommended ambient temperature range for the
charging system during charging is 0oC -40oC.
