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
6
of overheating, possible burns and even an explo-
sion.
4. If electrolyte gets into your eyes, rinse them out
with clear water and seek medical attention 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 conduc-
tive material.
(2) Avoid storing battery cartridge in a container
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 flow,
overheating, possible burns and even a break-
down.
6. Do not store the tool and battery cartridge in loca-
tions where the temperature may reach or exceed
50°C (122°F).
7. Do not incinerate the battery cartridge even if it is

Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the battery
cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room tempera-
ture at 10°C - 40°C (50°F - 104°F). Let a hot battery
cartridge cool down before charging it.
SAVE THESE INSTRUCTIONS.
