READ AND UNDERSTAND ALL INSTRUCTIONS.
Failure to follow the safety rules listed below may result in
electric shock, fire, and/or personal injury:
• Do not abuse the cord. Never use the cord to carry the
tool. Never pull on the cord in order to disconnect it from
the outlet. Keep the cord away from heat, oil, sharp
edges, and moving parts. Replace a damaged cord
immediately. A damaged cord may create a fire.
• Do not place the charger where the power cord can be
stepped on, tripped over, or subjected to damage.
• A battery-operated tool that uses internal batteries or a
separate battery pack must be recharged only with the
specific charger that is designed for that battery. A charger
that may be suitable for one type of battery may create a
risk of fire if it is used with another battery.
• Only use a battery-operated tool with the specific battery
pack that is designed for that tool. The use of any other
battery may create a risk of fire.
In the event of a malfunction or breakdown, grounding
provides the path of least resistance for an electric
current, and reduces the risk of electric shock.
This battery charger is double insulated, and has a
two-pronged polarized plug (one blade is wider than the
other). This plug will only fit into a polarized outlet one
way. If the plug does not fit in the outlet properly, reverse
the plug. If it still does not fit, contact a qualified electri-
cian to install the proper type of outlet.
DO NOT alter the plug in any way.
IN ALL cases, verify that the outlet is properly grounded.
If you are not sure, have the outlet checked by a certified
electrician.
Do not use an extension cord for the charger unless it is
absolutely necessary. If an extension cord is required, verify
that the cord is in good condition.
Use an extension cord that is heavy enough to carry the
current that the charger will draw. An undersized extension
cord will cause a drop in line voltage, which will result in loss
of power and overheating.
The table below shows the correct size of extension cord to
use, depending on the length of the cord and the amperage
rating that is listed on the charger's nameplate. When in
doubt, use the next heavier gauge. The smaller the gauge
number is, the heavier the cord.
Verify that extension cord is properly wired and in good
condition. Always replace a damaged cord or have it
repaired by a qualified electrician. Keep extension cords
away from sharp objects, excessive heat, and damp or wet
areas.
Use a separate electrical circuit for power tools. Do not use
any other voltage or power source than common household
120 V electrical power. The circuit must be equipped with not
less than #12 wiring, and should be protected with a 15 A
time-delayed fuse. Before connecting the charger to the
power line, verify that the electrical current is rated the same
as the current that is stamped on the charger's nameplate.
To reduce the risk of the charger cord disconnecting from the
extension cord during operation, tie them together in a knot.
