IMPORTANT SAFETY
INSTRUCTIONS
FOR BATTERY CARTRIDGE
1. Before using battery cartridge, read all instruc-
tions and cautionary markings on (1) battery
charger, (2) battery, and (3) product using
battery.
2. Do not disassemble battery cartridge.
3. If operating time has become excessively
shorter, stop operating immediately. It may
result in a risk of overheating, possible burns
and even an explosion.
If electrolyte gets into your eyes, rinse them
out with clear water and seek medical atten-
tion right away. It may result in loss of your
eyesight.
5. Do not short the battery cartridge:
(1) Do not touch the terminals with any con-
ductive material.
(2) Avoid storing battery cartridge in a con-
tainer with other metal objects such as
nails, coins, etc.
(3) Do not expose battery cartridge to water
or rain.
A battery short can cause a large current
breakdown.
6. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).
Do not incinerate the battery cartridge even if
it is severely damaged or is completely worn
8. Be careful not to drop or strike battery.
9. Do not use a damaged battery.
10. Follow your local regulations relating to dis-
posal of battery.
SAVE THESE INSTRUCTIONS.
Tips for maintaining maximum
battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the bat-
tery cartridge when you notice less tool power.
2. Never recharge a fully charged battery car-
tridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room tem-
perature at 10°C - 40°C (50°F - 104°F). Let a hot
battery cartridge cool down before charging it.
Charge the battery cartridge once in every six
months if you do not use it for a long period of
time.
