INSTRUCTIONS
This manual contains critical safety and operating
instructions for the tool, battery charger, and batteries.
2. Before using battery charger, read all instructions and
cautionary markings on (1) battery charger, (2) battery,
and (3) product using battery.
3. CAUTION - To reduce risk of injury, charge only MATCO
rechargeable batteries marked on the charger label.
Other types of batteries may burst causing personal
injury and damage.
4. Do not expose charger to rain or snow.
5. Use of an attachment not recommended or sold by the
battery charger manufacturer may result in a risk of fire,
electric shock, or injury to persons.
6. To reduce risk of damage to electric plug and cord, pull by
plug rather than cord when disconnecting charger.
7. Make sure cord is located so that it will not be stepped on,
tripped over, or otherwise subjected to damage or stress.
8. An extension cord should not be used unless absolutely
necessary. Use of improper extension cord could result in
a risk of fire and electric shock. If extension cord must be
used, make sure:
a. That pins on plug of extension cord are the same number
size, and shape as those of plug on charger;
b. That extension cord is properly wired and in good
electrical condition;

been dropped, or otherwise damaged in any way;
take it to a MATCO AUTHORIZED service facility.
11. Do not disassemble charger or battery cartridge;
take it to your MATCO AUTHORIZED distributor service
facility. Incorrect reassembly may result in a risk
of electric shock or fire.
12. To reduce risk of electric shock, unplug charger from
outlet before attempting any maintenance or cleaning.
Turning off controls will not reduce this risk.
