Wear ear protection.
VIBRATION INFORMATION
Vibration total values (triax vector sum) determined
according to EN 60745:
Typical
weighted
vibration
Vibration emission value ah= 9,457m/s2
Uncertainty K = 1.5m/s²
The declared vibration total value may be used for
comparing one tool with another, and may also be
used in a preliminary assessment of exposure.
WARNING: The vibration emission value
during actual use of the power tool can differ
from the declared value depending on the ways in
which the tool is used dependant on the following
examples and other variations on how the tool is
used:
How the tool is used and the materials being cut or
drilled.
The tool being in good condition and well
maintained
The use the correct accessory for the tool and
ensuring it is sharp and in good condition.
The tightness of the grip on the handles and if any
anti vibration accessories are used.
And the tool is being used as intended by its design
and these instructions.
This tool may cause hand-arm vibration
syndrome if its use is not adequately
managed.
WARNING: To be accurate, an estimation of
exposure level in the actual conditions of use
should also take account of all parts of the
operating cycle such as the times when the tool is
switched off and when it is running idle but not
actually doing the job.This may significantly reduce
the exposure level over the total working period.
Helping to minimise your vibration exposure risk.
Always use sharp chisels, drills and blades
Maintain this tool in accordance with these
instructions and keep well lubricated (where
appropriate)
If the tool is to be used regularly then invest in anti
vibration accessories.
Avoid using tools in temperatures of 10°C or less
Plan your work schedule to spread any high
vibration tool use across a number of days.

IMPACT WRENCH SAFETY
WARNING
1. Hold power tool by insulated gripping
surfaces, when performing an operation
where the fastener may contact hidden
wiring. Fasteners contacting a “live” wire may
make exposed metal parts of the power tool
“live” and could give the operator an electric
shock.
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.
e) In the event of battery leaking, do not
allow the liquid to come into contact
with the skin or eyes. If contact has been
made, wash the affected area with copious
amounts of water and seek medical advice.
f) Seek medical advice immediately if a cell
or battery pack has been swallowed.
g) Keep battery pack clean and dry.
h) Wipe the battery pack terminals with a
clean dry cloth if they become dirty.
i) Battery pack needs to be charged before
use. Always refer to this instruction and
use the correct charging procedure.
j) Do not maintain battery pack on charge
when not in use.
k) After extended periods of storage, it may
be necessary to charge and discharge
the battery pack several times to obtain
maximum performance.
l) Battery pack gives its best performance
when it is operated at normal room
temperature (20°C±5°C).
m) When disposing of battery packs, keep
battery packs of different electrochemical
systems separate from each other.
n) Recharge only with the charger specified
by WORX. Do not use any charger other
than that specifically provided for use with
the equipment. A charger that is suitable for
one type of battery pack may create a risk of fire
when used with another battery pack.
o) Do not use any battery pack which is not
designed for use with the equipment.
p) Keep battery pack out of the reach of
children.
q) Retain the original product literature for
future reference.
r) Remove the battery from the equipment
when not in use.
s) Dispose of properly.

Operating the On/Off Switch
WARNING: Do not operate

speed because excess heat will
be produced internally.
See Fig. F
Using The LED Light
Before operation, the LED light
will be activated when the On/Off
switch is slightly depressed, 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 flashing 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 theTrigger Switch
on the tool and stop the application
that caused the tool to become
overloaded.Then pull theTrigger
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 theTool and Battery
cool before pulling theTrigger 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.

TROUBLE SHOOTING
1. 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.
2. 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 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
30oC as this will affect performance.
MAINTENANCE
Remove the battery pack from the machine
before carrying out any adjustment,
servicing or maintenance.
Your power tool requires no additional lubrication
or maintenance.
Your power tool requires no additional lubrication
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. Occasionally you may see sparks through
the ventilation slots. This is normal and will not
damage your power tool.
ENVIRONMENTAL
PROTECTION
Waste electrical products should not be
disposed of with household waste. Please
recycle where facilities exist. Check with your
Local Authority or retailer for recycling advice.
