GENERAL POWER TOOL SAFETY WARNINGS

WARNING Read all safety warnings and instructions.

Failure to follow the

warnings and instructions may result in electr ic 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.
b) Do not operate power tools in explosive atmospheres, such as in the presence

of flammable liquids, gases or dust.

Cluttered or dark areas invite accidents.

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.

f) If operating a power tool in a damp location is unavoidable, use a residual

current device (RCD) protected supply.

Use of a cord suitable for outdoor use reduces the risk of electric shock.

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 protec tion
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

3

tool.

Carrying power tools with your finger on t he 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.

better control of the power tool in unexpected situations.

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.

Such preventive safety measures reduce the risk of star ting the power

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 tools
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 shar p

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 and in the manner intended for the particular type of power tool,
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.

SAFETY INSTRUCTIONS FOR ALL OPERATIONS 
Safety warnings common for grinding, sanding, wire brushing, polishing, carving or
abrasive cutting-off operations:

a) This power tool is intended to function as a grinder, sander, wire brush,

polisher, carving or cut-off tool. Read all safety warnings, instructions,
illustrations and specifications provided with this power tool.

This will ensure that the safety of the power tool is maintained.

Liquid ejected from the batter y may cause irritation

Failure to follow all

instructions listed below may result in electric shock, fire and/or serious injury.

b) Do not use accessories which are not specifically designed and recommended

by the tool manufacturer.

Just because the accessory can be attached to your power

tool, it does not assure safe operation.

c) The rated speed of the accessories must be at least equal to the maximum

speed setting marked on the power tool.

Grinding accessories running faster than

their rated speed can break and fly apart.

d) The outside diameter and the thickness of your accessory must be within

the capacity rating of your power tool.

Incorrectly sized accessories cannot be

adequately controlled.

e) The arbour size of wheels, sanding drums or any other accessory must properly

fit the spindle or collet of the power tool.

Accessories that do not match the
mounting hardware of the power tool will run out of balance, vibrate excessively and
may cause loss of control.

f) Mandrel mounted wheels, sanding drums, cutters or other accessories must

be fully inserted into the collet or chuck.

If the mandrel is insufficiently held and/
or the overhang of the wheel is too long, the mounted wheel may become loose and be
ejected at high velocity.

g) Do not use a damaged accessory. Before each use inspect the accessory such

as abrasive wheels for chips and cracks, sanding drum for cracks, tear or
excess wear, wire brush for loose or cracked wires. If power tool or accessory
is dropped, inspect for damage or install an undamaged accessory. After
inspecting and installing an accessory, position yourself and bystanders away
from the plane of the rotating accessory and run the power tool at maximum
no-load speed for one minute.

Damaged accessories will normally break apart during

this test time.

5

h) Wear personal protective equipment. Depending on application, use face

shield, safety goggles or safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron capable of stopping small
abrasive or workpiece fragments.

The eye protection must be capable of stopping
flying debris generated by various operations. The dust mask or respirator must be
capable of filtrating particles generated by your operation. Prolonged exposure to high
intensity noise may cause hearing loss.

i) Keep bystanders a safe distance away from work area. Anyone entering the

work area must wear personal protective equipment.

Fragments of workpiece
or of a broken accessory may fly away and cause injury beyond immediate area of
operation.

j) Hold power tool by insulated gripping surfaces only, when performing an

operation where the cutting accessory may contact hidden wiring.

accessory contacting a “live” wire may make exposed metal parts of the power tool
“live” and could give the operator an electric shock.

k) Always hold the tool firmly in your hand(s) during the start-up.

The reaction

torque of the motor, as it accelerates to full speed, can cause the tool to twist.

l) Use clamps to support workpiece whenever practical. Never hold a small

workpiece in one hand and the tool in the other hand while in use.

Clamping a
small workpiece allows you to use your hand(s) to control the tool. Round material such
as dowel rods, pipes or tubing have a tendency to roll while being cut, and may cause
the bit to bind or jump toward you.

m) Position the cord clear of the spinning accessory.

FURTHER SAFETY INSTRUCTIONS FOR ALL OPERATIONS
Kickback and related warnings

Kickback is a sudden reaction to a pinched or snagged rotating wheel, sanding band, brush
or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory

which in turn causes the uncontrolled power tool to be forced in the direction opposite of the
accessory’s rotation.
For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the
wheel that is entering into the pinch point can dig into the surface of the material causing the
wheel to climb out or kick out. The wheel may either jump toward or away from the operator,
depending on direction of the wheel’s movement at the point of pinching. Abrasive wheels
may also break under these conditions.
Kickback is the result of power tool misuse and/or incorrect operating procedures or
conditions and can be avoided by taking proper precautions as given below.

a) Maintain a firm grip on the power tool and position your body and arm to allow

you to resist kickback forces.

The operator can control kickback forces, if proper

precautions are taken.

b) Use special care when working corners, sharp edges etc. Avoid bouncing and

snagging the accessory.

Corners, sharp edges or bouncing have a tendency to snag

the rotating accessory and cause loss of control or kickback.

c) Do not attach a toothed saw blade.

Such blades create frequent kickback and loss of

control.

d) Always feed the bit into the material in the same direction as the cutting

edge is exiting from the material (which is the same direction as the chips are
thrown).

Feeding the tool in the wrong direction causes the cutting edge of the bit to

climb out of the work and pull the tool in the direction of this feed.

e) When using rotary files, cut-off wheels, high-speed cutters or tungsten carbide

cutters, always have the work securely clamped.

These wheels will grab if they
become slightly canted in the groove, and can kickback. When a cut-off wheel grabs,
the wheel itself usually breaks. When a rotary file, high-speed cutter or tungsten carbide
cutter grabs, it may jump from the groove and you could lose control of the tool .

SAFETY WARNINGS SPECIFIC FOR GRINDING AND ABRASIVE CUTTINGOFF OPERATIONS
a) Use only wheel types that are recommended for your power tool and only for

recommended applications. For example: do not grind with the side of a cut-off
wheel.

Abrasive cut-off wheels are intended for peripheral grinding, side forces applied

to these wheels may cause them to shatter.

b) For threaded abrasive cones and plugs use only undamaged wheel mandrels

with an unrelieved shoulder flange that are of correct size and length.

Proper

mandrels will reduce the possibility of breakage.

c) Do not “jam” a cut-off wheel or apply excessive pressure. Do not attempt to

make an excessive depth of cut.

Overstressing the wheel increases the loading
and susceptibility to twisting or snagging of the wheel in the cut and the possibility of
kickback or wheel breakage.

d) Do not position your hand in line with and behind the rotating wheel.

When the
wheel, at the point of operation, is moving away from your hand, the possible kickback
may propel the spinning wheel and the power tool directly at you.

e) When wheel is pinched, snagged or when interrupting a cut for any reason,

switch off the power tool and hold the power tool motionless until the wheel

7

comes to a complete stop. Never attempt to remove the cut-off wheel from the
cut while the wheel is in motion otherwise kickback may occur.

Investigate and

take corrective action to eliminate the cause of wheel pinching or snagging.

f) Do not restart the cutting operation in the workpiece. Let the wheel reach full

speed and carefully re-enter the cut.

The wheel may bind, walk up or kickback if the

power tool is restarted in the workpiece.

g) Support panels or any oversized workpiece to minimize the risk of wheel

pinching and kickback.

Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near the line of cut and near the edge of
the workpiece on both sides of the wheel.

h) Use extra caution when making a “pocket cut” into existing walls or other blind

areas.

The protruding wheel may cut gas or water pipes, electrical wiring or objects that

can cause kickback.

SAFETY WARNINGS SPECIFIC FOR WIRE BRUSHING OPERATIONS
a) Be aware that wire bristles are thrown by the brush even during ordinary

operation. Do not overstress the wires by applying excessive load to the brush.

The wire bristles can easily penetrate light clothing and/or skin.

b) Allow brushes to run at operating speed for at least one minute before using

them. During this time no one is to stand in front or in line with the brush.

bristles or wires will be discharged during the run-in time.

8

c) Direct the discharge of the spinning wire brush away from you.

Small particles
and tiny wire fragments may be discharged at high velocity during the use of these
brushes and may become imbedded in your skin.

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 toget her 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.

Loose

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) Recharge only with the charger specified by Worx. Do not use

CHARGING PROCEDURE

NOTE: Before using the tool, read the

instruction book carefully.

CHARGING INSTRUCTIONS

1. CHARGING YOUR BATTERY PACK
WARNING The charger and battery pack are

specifically designed to work together so do

not attempt to use any other devices. Never insert
or allow metallic objects into your charger or battery
pack connections because an electrical failure and
hazard will occur.

2. BEFORE USING YOUR CORDLESS TOOL

Your battery pack is UNCHARGED and you must
charge once before use.

3. HOW TO CHARGE YOUR BATTERY

CHARGING PROCEDURE

1) Plug the charger into an appropriate outlet.

2) Slide the battery pack into the charger. The

LIGHT (3) will become green and flash to show
charging has started.

3) After charging approx 1-2 hours, the light will stay

green without flashing, which means the battery
is full, and charging is completed.

WARNING When battery charge runs out
after continuous use or exposure to direct

sunlight or heat, allow time for the battery to
cool down before re-charging to achieve the full
charge.

CHARGING INDICATOR

This charger is designed to detect some problems
that can arise with batter y packs. Indicator lights
indicate problems (see table below). If this occurs,
insert a new battery pack to determine if the charger
is OK. If the new battery charges correctly, then the
original pack is defective and should be returned
to a service center or recycling service center. If the
new battery pack displays the same problem as the
original Battery Pack, have the charger tested at an
authorized service center.

BATTERY TEMPERATURE PROTECTION

This charger has a battery temperature protection
feature. When the charger detects a battery pack
that is too hot or cold (the light will be red and flash),
it automatically activates the protection circuit , and
suspends charging until the battery pack has reached
the correct temperature. The charging process will
then automatically begin (the light will be green and
flash). This feature ensures maximum battery life.

LEAVING THE BATTERY PACK IN THE CHARGER

If a fully charged battery pack is left in the charger,
the Light will remain green. The battery pack will
remain charging with a maintenance trickle current .

DEFECTIVE BATTERY PACKS

This charger will detect a defective batter y pack.
When a defective battery pack is inserted into the
charger, the charger will try to repair it. This process
will last about 30mins (the light will be green and
flash). If the repair is successful, the charger will
automatically begin to charge the battery pack to the
highest capacity possible (the light will be green and
flash). If the light becomes solid red, the battery pack
is dead.
NOTE: Repaired battery packs are still usable but
should not be expected to perform as much work as
new battery packs.

IMPORTANT CHARGING NOTES:

1. For a new battery or a batter y that has been
in storage for sometime, please recharge the
battery before use. If you want to store the
battery for a long time, please fully charge the
battery pack to ensure maximum batter y life.

2.

Longer life and better performance can be
obtained if the battery pack is charged when the
air temperature is between (180C-240C). Do not
charge the battery pack in air temperatures below
00C, or above 400C. This is important as it can
prevent serious damage to the battery pack.

3. Never freeze your charger or immerse charger in
water or any other liquid.

4. When the batter y pack fails to produce sufficient
power on jobs that were previously done easily,
please recharge your battery, do not continue
to use under this condition. You may charge a
partially used pack whenever you desire with no
adverse affect on the batter y pack.

5. When charging it is normal that the charger and

battery pack may become warm to touch.

6. If the batter y pack does not charge properly:
a. Check current at power outlet by plugging in

another appliance.

b. Plug and unplug to check whether the charger is

ok
c. Check whether the battery has been damaged
d. Move the charger and batter y pack to a location

where the surrounding air temperature is

approximately 180-240C.
e. If the charging problem persists, take the tool,

battery pack and charger to an authorized

service center.
f. Under certain conditions, when the charger is

plugged into the power supply, the exposed

charging contacts inside the charger can be

shorted by foreign material. Foreign materials of

a conductive nature such as metallic particles

should be kept away from charger cavities.

Always unplug the charger from the power

supply when there is no battery pack in the

charger or before attempting to clean.

PROBLEM SOLUTION

I CANNOT FIT THE BATTERY INTO THE BATTERY
CHARGER. WHY?

a) Check if the charger and the batter y pack are

10

specifically designed for working together.
b) 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 indicator light

should be green and flash when the battery is

charging.

REASONS FOR DIFFERENT
CHARGING TIMES

The charging time can be affected by many reasons
which are not defects in your product.
a) If the battery pack is only partly discharged it

may be re-charged in less than rated charging

time.
b) If the batter y pack and ambient temperature are

very cold/ hot, it may take longer to re-charge.

Please find an appropriate environment with

proper air temperature to start charging.
c) If the battery pack is ver y hot, remove battery

pack from the charger and allow battery pack

to cool first to ambient temperature and then

recharging can be started.
