IMPORTANT SAFETY INSTRUCTIONS FOR
CHARGER & BATTERY CARTRIDGE
ENC004-1
1. Before using battery cartridge, read all instruc-
tions and cautionary markings on (1) battery
charger, (2) battery, and (3) product using bat-
tery.
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.
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. Always cover the battery terminals with the bat-
tery cover when the battery cartridge is not
used.
6. 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.
7. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).
8. Do not incinerate the battery cartridge even if it
is severely damaged or is completely worn out.
The battery cartridge can explode in a fire.
9. Be careful not to drop or strike 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 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 bat-
tery cartridge cool down before charging it.
4. Charge the Nickel Metal Hydride battery car-
tridge when you do not use it for more than six
months.
ADDITIONAL SAFETY RULES
FOR TOOL
1. Be aware that this is always in an operating con-
dition, because it does not have to be plugged
into an electrical outlet.
2. Check the wheel carefully for cracks or damage
before operation. Replace cracked or damaged
wheel immediately.
3. Use only flanges specified for this tool.
4. Be careful not to damage the spindle, flanges
(especially the installing surface) or bolt. Dam-
age to these parts could result in wheel break-
age.
5. Hold the tool firmly.
6. Keep hands away from rotating parts.
7. Make sure the wheel is not contacting the work-
piece before the switch is turned on.
8. Wait until the wheel attains full speed before cut-
ting.
9. Stop operation immediately if you notice any-
thing abnormal.
10. Do not attempt to lock the trigger in the “ON”
position.
