instructions.
IMPORTANT SAFETY INSTRUCTIONS FOR
CHARGER & 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.
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 breakdown.
7. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).
ENC004-1
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 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 temperature at 10°C – 40°C (50°F – 104°F). Let a hot battery cartridge cool down before charging it.
4. Charge the Nickel Metal Hydride battery cartridge 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 operation.
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 foreign 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.
SAVE THESE INSTRUCTIONS.

OPERATING INSTRUCTIONS
Installing or removing battery cartridge (Fig. 1)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, open the cover and
withdraw the battery cartridge from the tool while
pressing the buttons on both sides of the cartridge.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If not, it may accidentally fall out
of the tool, causing injury to you or someone around
you.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Switch action (Fig. 2)
CAUTION:
Before inserting the battery cartridge into the tool, always
check to see that the switch trigger actuates properly and
returns to the “OFF” position when released.
To start the tool, simply pull the trigger. Release the trigger to stop.
Operation (Fig. 3)
Hold the tool straight when inserting/operating. Use the
tool within the effective vibration range at equidistant
intervals. The effective air bubble removal range is about
ten times the diameter of the vibrating head, or around
250 mm with this tool.
Do not use this tool to move concrete within a form. The
mortar will just move away and the coarse aggregate will
remain, causing segregation.
Effective leveling and removal of air bubbles
Removal of the air bubbles is complete after you have
worked the tool throughout each effective range, the concrete stops shrinking, and the mortar has risen evenly to
the surface, giving off a light appearance. Gently remove
the operating tool not to leave holes.
NOTE:
• Vibrating too long in a single place causes concrete
segregation.
• When the coarse aggregate segregates when placing
concrete, shovel out the coarse aggregate and put it
where there is plenty of mortar. Then use the tool on it.
Don’t leave coarse aggregate in the segregated condition.
When concreting a slope site, always pour from the bottom at the beginning. This way the weight of the freshly
poured concrete and vibration will lead to effective
removal of air bubbles. (Fig.4)
Conversely, if the pouring is done first from above, the
mortar will separate and eventually slide to the bottom.
MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on
the tool.
To maintain product safety and reliability, repairs, maintenance or adjustment should be carried out by a Makita
Authorized Service Center.
