GENERAL SAFETY RULES
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable liq-
uids, gases or dust. Power tools create sparks which
may ignite the dust or fumes.
3. Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never mod-
ify 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.
2. Avoid body contact with earthed or grounded surfac-
es such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body
is earthed or grounded.
3. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
4. Do not abuse the cord. Never use the cord for car-
rying, 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.
5. When operating a power tool outdoors, use an ex-
tension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric
shock.
6. If operating a power tool in a damp location is un-
avoidable, use a ground fault circuit interrupter (GFCI)
protected supply. Use of a GFCI reduces the risk of elec-
tric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use com-
mon 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 inatten-
tion while operating power tools may result in serious
personal injury.
2. Use personal protective equipment. Always wear
eye protection. Protective equipment such as a respira-
tory mask, non-skid safety shoes and hearing protection
used for appropriate conditions will reduce the risk of
personal injury.
3. 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
energizing power tools that have the switch on invites
accidents.
4. 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.
5. Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jew-
elry. Keep your hair and clothing away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
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.

GENERAL SAFETY RULES
7. 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.
POWER TOOL USE AND CARE
1. 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.
2. 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.
3. 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.
4. 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 us-
ers.
5. 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 opera-
tion. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained
power tools.
6. Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits, etc.
in accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situa-
tion.
8. Use clamps to secure your workpiece to a stable
surface. Holding a workpiece by hand or using your
body to support it may lead to loss of control.
9. KEEP GUARDS IN PLACE and in working order.

ABOUT THE BATTERY
ABOUT THE BATTERY
1. The battery pack supplied with your cordless tool is only partially charged. The battery pack has to
be charged completely before you use the tool for the first time.
2. For optimum battery performance, avoid low discharge cycles by charging the battery pack fre-
quently.
3. Lithium-ion batteries are subject to a natural aging process. The battery pack must be replaced at the
latest when its capacity falls to just 80% of its capacity when new. Weakened cells in an aged battery
pack are no longer capable of meeting the high power requirements needed for the proper operation of
your tool, and therefore pose a safety risk.
4. Do not throw battery packs into an open fire as this poses a risk of explosion. Do not ignite the bat-
tery pack or expose it to fire.
5. Do not exhaustively discharge batteries. Exhaustive discharge will damage the battery cells. The
most common cause of exhaustive discharge is lengthy storage or non-use of partially discharged bat-
teries. Stop working as soon as the performance of the battery falls noticeably or the electronic protec-
tion system triggers. Place the battery pack in storage only after it has been fully charged.
6. Protect batteries and the tool from overloads. Overloads will quickly result in overheating and cell
damage inside the battery housing even if this overheating is not apparent externally.
7. Avoid damage and shocks. Immediately replace batteries that have been dropped from a height of
more than one meter or those that have been exposed to violent shocks, even if the housing of the
battery pack appears to be undamaged. The battery cells inside the battery may have suffered serious
damage. In such instances, please read the waste disposal information for proper battery disposal.
8. If the battery pack suffers overloading and overheating, the integrated protective cutoff will switch
off the equipment for safety reasons.
9. Use only original battery packs. The use of other batteries poses a fire risk and may result in injuries
or an explosion.
10. You must fully charge the battery every 3 months. See the tables on pages 13 & 14 to understand
what the LED lights on your battery and charger indicate.
WARNING: 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 ad-
vice.
WARNING: To reduce risk of injury, charge only WEN batteries with this charger. Other types
of batteries may burst causing personal injury and damage.

11
ABOUT THE CHARGER
Protect the battery charger and its cord from damage. Keep the charger and its cord away from heat,
oil and sharp edges. Electrical plugs must match the outlet. Never modify the plug in any way. Do not
use any adapter plugs with grounded appliances. Unmodified plugs and matching outlets will reduce
the risk of electric shock.
Keep the battery charger, battery pack(s) and the cordless tool out of the reach of children. Do not use
the supplied battery charger to charge other cordless tools. During periods of heavy use, the battery
pack will become warm. Allow the battery pack to cool to room temperature before inserting it into the
charger to recharge.
Do not overcharge batteries. Do not exceed the maximum charging times. These charging times only
apply to discharged batteries. Frequent insertion of a charged or partially charged battery pack will
result in overcharging and cell damage. Do not leave battery in the charger for days on end. Never use
or charge a battery if you suspect that it has been more than 12 months since the last time they were
charged. There is a high probability that the battery pack has already suffered dangerous damage (ex-
haustive discharge). Do not use battery that have been exposed to heat during the charging process, as
the battery cells may have suffered dangerous damage. Do not use battery that have suffered curvature
or deformation during the charging process or those that exhibit other atypical symptoms (gassing,
hissing, cracking, etc.)
ABOUT THE CHARGER
WARNING: 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 ad-
vice.
WARNING: To reduce risk of injury, charge only WEN batteries with this charger. Other types
of batteries may burst causing personal injury and damage.

12
1. EXAMINE EXTENSION CORD BEFORE USE. Make sure your extension cord is properly wired and in
good condition. Always replace a damaged extension cord or have it repaired by a qualified person before
using it.
2. DO NOT ABUSE EXTENSION CORD. Do not pull on cord to disconnect from receptacle; always discon-
nect by pulling on plug. Disconnect the extension cord from the receptacle before disconnecting the prod-
uct from the extension cord. Protect your extension cords from sharp objects, excessive heat and damp/
wet areas.
3. USE A SEPARATE ELECTRICAL CIRCUIT FOR YOUR TOOL. This circuit must not be less than a
12-gauge wire and should be protected with a 15A time-delayed fuse. Before connecting the motor to the
power line, make sure the switch is in the OFF position and the electric current is rated the same as the
current stamped on the motor nameplate. Running at a lower voltage will damage the motor.
When using an extension cord, be sure to use one heavy enough to carry the current your product will
draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The
table below shows the correct size to be used according to cord length and ampere rating. When in doubt,
use a heavier cord. The smaller the gauge number, the heavier the cord.
AMPERAGE REQUIRED GAUGE FOR EXTENSION CORDS
25 ft. 50 ft. 100 ft. 150 ft.
2.5A 18 gauge 16 gauge 14 gauge 12 gauge
GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
ELECTRICAL INFORMATION
1. POLARIZED PLUGS. To reduce the risk of electric shock, this equipment has a polarized plug (one blade
is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in
the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a proper outlet. Do
not modify the machine plug or the extension cord in any way.
2. GROUND FAULT CIRCUIT INTERRUPTER PROTECTION (GFCI) should be provided on the circuit or outlet
used for this power tool to reduce the risk of electric shock.
3. SERVICE AND REPAIR. To avoid danger, electrical appliances must only be repaired by qualified service
technician using original replacement parts.
