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.

Always keep your hands and face away from
vibrating head when operating. 

2.

Switch off the tool immediately if you notice
abnormal noise or something faulty during oper-
ation. 

3.

Inspect the tool carefully for breakage, cracks or
deformation if you accidentally drop it or strike it
against something. 

4.

Do not charge the battery cartridge in locations
where lacquer, paint, benzene, thinner, gasoline,
gas or adhesive are stored/used. 

5.

Do not charge on cardboard or paper, cloth or
bedding, straw mats, carpeting, vinyl or the like. 

6.

Do not charge in a dusty place or where lint
accumulates. 

7.

Do not allow pieces of metal, water or other for-
eign objects to get into the charger port where
the charging terminals are located. 

8.

Do not carry the tool with finger on switch. 

9.

Do not set the tool down and switch it on. The
vibrating head may whip around out of control
and cause an accident. 

10. Be careful not to allow water, wet concrete or the

like to get into the tool. Do not let the tool fall
into wet concrete. 

11. Insert the vibrating head carefully between iron/

steel frames or reinforcing rods not to come in
contact with them. 

12. Do not crush or twist the fexible hose. 
13. Do not overly bend the flexible hose. 
14. Use a wet cloth or the like to carefully wipe off

any wet concrete left on the tool after use. Extra
care should be given to thorough cleaning of the
vents, switch area, cover openings, etc.
