General Power Tool Safety Warnings
WARNING! Read all safety warnings
and 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.
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.
PERSONAL SAFETY
a)
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.
b)
Do not overreach. Keep proper
footing and balance at all times.
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)
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.
BATTERY TOOL USE AND CARE
a)
Recharge only with the charger specified
by the manufacturer.
b)
Use power tools only with specifically
designated battery packs.
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
water. If liquid contacts eyes, additionally
seek medical help.
Liquid ejected from the
battery may cause irritation or burns.
Important Safety Instructions for All
Battery Chargers
WARNING:
Shock hazard. Do not allow
any liquid to get inside charger. Electric
shock may result.
CAUTION:
Burn hazard. To reduce
the risk of injury, charge only D
E
WALT
rechargeable batteries. Other types of
batteries may burst causing personal
injury and damage.
CAUTION:
Under certain conditions,
with the charger plugged in to the
power supply, the exposed charging
contacts inside the charger can be
shorted by foreign material.
• DO NOT attempt to charge the battery pack
with any chargers other than the ones in
this manual.
The charger and battery pack are
specifically designed to work together.
• These chargers are not intended for
any uses other than charging D
E
WALT
rechargeable batteries.
Any other uses
may result in risk of fire, electric shock or
electrocution.
• Do not expose charger to rain or snow.
• Pull by plug rather than cord when
disconnecting charger.
• Do not use an extension cord unless it
is absolutely necessary.
• Do not place any object on top of charger
or place the charger on a soft surface that
might block the ventilation slots and result
in excessive internal heat.
• Do not operate charger with damaged cord
or plug
•
Do not operate charger if it has received
a sharp blow, been dropped, or otherwise
damaged in any way.
• Do not disassemble charger; take it to an
authorized service center when service or
repair is required.
• Disconnect the charger from the outlet
before attempting any cleaning. This will
reduce the risk of electric shock.
Removing
the battery pack will not reduce this risk.
• NEVER
attempt to connect 2 chargers together.
Charging Procedure
1. Plug the charger (j) into an appropriate outlet
before inserting battery pack.
2. Insert the battery pack (h) into the charger.

capacity. Battery packs should be refreshed weekly
or whenever the pack no longer delivers the same
amount of work.
To refresh your battery pack, place the battery in the
charger as usual. Leave the battery pack for at least
8 hours in the charger.
Hot/Cold Pack Delay
When the charger detects a battery that is too hot
or too cold, it automatically starts a Hot/Cold Pack
Delay, suspending charging until the battery has
reached an appropriate temperature. The charger
