GENERAL POWER TOOL
SAFETY WARNINGS

WARNING: Read all safety warnings
and all 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 battery­operated (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, clothing and
gloves away from moving parts. Loose

clothes, jewellery or long hair can be caught in
moving parts.

If devices are provided for the connection

g)

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.

WX386 WX386.1 WX386.2 WX386.4 WX386.9

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

4

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.

DRILL SAFETY WARNINGS

1. Wear ear protectors when impact drilling.

Exposure to noise can cause hearing loss.

2. Use auxiliary handle(s), if supplied with the

tool. Loss of control can cause personal injury.

3. Hold 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.

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.

Battery pack needs to be charged before use.

i)

Always refer to this instruction and use the

correct charging procedure.
j) Do not maintain battery pack on charge

when not in use.

After extended periods of storage, it may

k)

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.

VIBRATION INFORMATION

Vibration total values (triax vector sum) determined
according to EN 60745:

Impact drilling
into concrete

Drilling into metal

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 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 minimize 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.
Plan your work schedule to spread any high vibration
tool use across a number of days.

LED LIGHT INDICATOR (See Fig. F)

To turn on the light, press the on/off switch and make
sure the forward/reverse rotation control is on right/
left position. When you release the on/off switch, the
light will be off.
LED lighting increases visibility-great for dark or
enclosed area. LED is also a battery capacity indicator.
It will flash when power gets low.
The tool and battery pack are equipped with a
protection system. When the LED Light is quickly
flashing 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 pack 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 Pack are
overheated. In this situation, let the Tool and Battery
Pack 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 Pack.

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

Cordless Hammer Drill

WX386 WX386.1 WX386.2 WX386.4 WX386.9

the Forward and Reverse Switch putting it into the
required rotation position. Push the trigger and the
drill will start to rotate (See Fig. C1, C2, C3)

2. THE DRILL STOPS BEFORE THE SCREW IS
COMPLETELY TIGHTENED. WHY?

Verify the torque position of the Torque Adjustment
Ring, you can find the Torque Adjustment Ring
between the Chuck and the drill body. Position
1 is the lowest torque (screw driving force) and
position 18 is the highest torque (screw driving
force). Position
is for hammer drill operation. Regulate the Torque
Adjustment Ring to a higher position to reach the
best result. (See Fig. E1, E2, E3)

3. I CAN NOT FIT THE BATTERY PACK INTO
THE BATTERY CHARGER. WHY?

The battery pack can be inserted into the charger
only in one direction. Turn the battery pack around
until it can be inserted into the slot. The charger LED
indicator should turn on when the battery pack 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 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 0
