ABOUT THE BATTERY
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 advice.
WARNING: To reduce risk of injury, charge only WEN batteries with this charger. Other types
of batteries may burst causing personal injury and damage.
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 frequently.
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 battery 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 batteries. Stop working as soon as the performance of the battery falls noticeably or the electronic protection 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.

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 advice.
WARNING: To reduce risk of injury, charge only WEN batteries with this charger. Other types
of batteries may burst causing personal injury and damage.
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 (exhaustive 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.)

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.
GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
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
25 ft. 50 ft. 100 ft. 150 ft.
2.5A 18 gauge 16 gauge 14 gauge 12 gauge
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 disconnect by pulling on plug. Disconnect the extension cord from the receptacle before disconnecting the product 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.
