BATTERY PACKS
Important Safety Instructions for
Battery Packs.
Your tool uses a 24.0 Volt DEWALT battery
pack. When ordering replacement battery
packs, be sure to include catalogue number
and voltage which is clearly marked on the
battery label (i.e., 24V DE0240).
The battery pack is not fully charged out of the kitbox. First read the safety
instructions below. Then follow charging notes and procedures.
• Do not incinerate the battery pack even if it is severely damaged or is
completely worn out. The battery pack can explode in a fire.
• A small leakage of liquid from the battery pack cells may occur under extreme
usage or temperature conditions. This does not indicate a failure. However, if
the outer seal is broken and this leakage gets on your skin:
a. Wash quickly with soap and water.
b. Neutralise with a mild acid such as lemon juice or vinegar.
c. If battery liquid gets into your eyes, flush them with clean water for a
minimum of 10 minutes and seek immediate medical attention. (Medical
note: The liquid is 25-35% solution of potassium hydroxide.)
• Never attempt to open the battery pack for any reason. If the plastic housing of
the battery pack breaks or cracks, immediately discontinue use and do not
recharge.
• Do not carry extra battery packs in aprons, pockets, or tool boxes along with
other metal objects. Battery pack could be short circuited causing damage to
the battery pack and possibly causing severe burns or fire.
• Charge the battery packs only in DeWALT chargers.
• NOTE: Review and observe all the safety instructions in the charger
instruction section of this manual.
• NOTE: The battery cells in your battery pack are the nickel-cadmium (NiCad)
type. Cadmium is considered to be a toxic material by the Environmental
Protection Agency. Before disposing of damaged or worn out NiCad battery
packs, check with your government Environmental Protection Agency to find
out about special restrictions on the disposal of these battery packs or return
them to a DeWALT authorised repair centre for recycling.
• The battery pack should not be subjected to wet conditions. Where a battery
pack has become wet the exterior of the battery pack should be dried with a
dry cloth prior to storage or use. If the battery pack has been fully submerged
the pack should be taken to a service centre to be opened and dried. The
battery pack should not be subjected to any external heating (ie heater or oven)
to dry the battery pack. Under no circumstances should a wet or damp
battery pack be placed in the battery charger as there is line
voltage present at the battery charger terminals.
• The battery pack should be handled with a degree of care and should not be
dropped or be subjected to severe impacts. A cracked or fractured battery
case should NEVER be placed in a charger to be recharged. In some cases
high voltage can be measured at the outside of a cracked battery pack and
electrocution is then a possibility.
• FAILURE TO OBSERVE THE CARE GUIDELINES OUTLINED
ABOVE CAN BE CONSIDERED ABUSE AND MAY VOID ANY
WARRANTY CLAIM
Important Information on Battery Packs
The battery cells contained in the battery packs supplied with this tool are NiCad
cells and their life will greatly depend on how they are cared for by you the operator.
The following details will assist you to obtain the maximum life from your battery
packs.
Temperature
• Battery packs should be kept as cool as is practicable whilst in use, charging
and also when in storage. Battery packs should not be left in areas where high
temperatures are experienced, including cars on hot days, small sheds in
summer, or work areas with ambient temperatures above 35°C.
Usage
• During use, do not overload the tool. If the battery pack is getting hot then
generally the tool is being overloaded. Overloading can be prevented by
ensuring the cutting tool is sharp, by ensuring the cutting tool is not too large for
the powertool and by not forcing the tool into the work piece.
• Where a battery pack has become hot in the tool, remove the battery pack from
the tool and allow the battery to cool as quickly as possible and then re-charge,
unless the battery pack is a fan-cooled unit. If your battery pack is a fan cooled
unit the fastest and best way to cool it down is to immediately put it into the
matching charger and turn it on.
• Never run a battery down to the point where the tool stops. DeWALT power tool
battery packs do not suffer from battery memory effect so there is no
