Electrical Safety  
Tool Use and Care  
4. A battery operated tool with integral bat-  
teries or a separate battery pack must be  
recharged only with the specified charger  
for the battery. A charger that may be suit-  
able for one type of battery may create a risk  
of fire when used with another battery.  
12. Use clamps or other practical way to  
secure and support the workpiece to a  
stable platform. Holding the work by hand or  
against your body is unstable and may lead  
to loss of control.  
13. Do not force tool. Use the correct tool for  
your application. The correct tool will do the  
job better and safer at the rate for which it is  
designed.  
5. Use battery operated tool only with specif-  
ically designated battery pack. Use of any  
other batteries may create a risk of fire.  
14. Do not use tool if switch does not turn it  
on or off. A tool that cannot be controlled  
with the switch is dangerous and must be  
repaired.  
Personal Safety  
6. Stay alert, watch what you are doing, and  
use common sense when operating a  
power tool. Do not use tool while tired or  
under the influence of drugs, alcohol, or  
medication. A moment of inattention while  
operating power tools may result in serious  
personal injury.  
15. Disconnect battery pack from tool or  
place the switch in the locked or off posi-  
tion before making any adjustments,  
changing accessories, or storing the tool.  
Such preventive safety measures reduce the  
risk of starting the tool accidentally.  
7. Dress properly. Do not wear loose cloth-  
ing or jewelry. Contain long hair. Keep  
your hair, clothing, and gloves away from  
moving parts. Loose clothes, jewelry, or long  
hair can be caught in moving parts.  
16. Store idle tools out of reach of children  
and other untrained persons. Tools are  
dangerous in the hands of untrained users.  
17. When battery pack is not in use, keep it  
away from other metal objects like: paper  
clips, coins, keys, nails, screws, or other  
small metal objects that can make a con-  
nection from one terminal to another.  
Shorting the battery terminals together may  
cause sparks, burns, or a fire.  
8. Avoid accidental starting. Be sure switch  
is in the locked or off position before  
inserting battery pack. Carrying tools with  
your finger on the switch or inserting the bat-  
tery pack into a tool with the switch on invites  
accidents.  
9. Remove adjusting keys or wrenches  
before turning the tool on. A wrench or a  
key that is left attached to a rotating part of  
the tool may result in personal injury.  
18. Maintain tools with care. Keep cutting  
tools sharp and clean. Properly maintained  
tools with sharp cutting edge are less likely to  
bind and are easier to control.  
10. Do not overreach. Keep proper footing  
and balance at all times. Proper footing and  
balance enable better control of the tool in  
unexpected situations.  
19. Check for misalignment or binding of  
moving parts, breakage of parts, and any  
other condition that may affect the tool’s  
operation. If damaged, have the tool ser-  
viced before using. Many accidents are  
caused by poorly maintained tools.  
11. Use safety equipment. Always wear eye  
protection. Dust mask, non-skid safety  
shoes, hard hat, or hearing protection must  
be used for appropriate conditions.  
20. Use only accessories that are recom-  
mended by the manufacturer for your  
model. Accessories that may be suitable for  
one tool may create a risk of injury when  
used on another tool.  
3
 
22. When servicing a tool, use only identical  
replacement parts. Follow instructions in  
the Maintenance section of this manual.  
Use of unauthorized parts or failure to follow  
Maintenance instructions may create a risk of  
shock or injury.  
SERVICE  
21. Tool service must be performed only by  
qualified repair personnel. Service or main-  
tenance performed by unqualified personnel  
may result in a risk of injury.

charging.  
4. When the charging light color changes from red to  
green, the charging cycle is complete.  
5. If you leave the battery cartridge in the charger after the  
charging cycle is complete, the charger will switch into  
its trickle charge (maintenance charge)mode.  
6. After charging, unplug the charger from the power

NOTE:  
The battery charger is for charging Makita battery  
cartridge. Never use it for other purposes or for other  
manufacturers batteries.  
When you charge a new battery cartridge or a battery  
cartridge which has not been used for a long period of  
time, it may not accept a full charge. This is a normal  
condition and does not indicate a problem. You can  
recharge the battery cartridge fully after discharging it  
completely and recharging a couple of times.  
If you charge a battery cartridge from a just operated  
tool or a battery cartridge which has been left in a  
location exposed to direct sunlight or heat for a long  
time, the charging light may flash in red color. If this  
occurs, wait for a while. Charging will begin after the  
battery cartridge cools. The battery cartridge will cool  
faster if you remove the battery cartridge from the high  
capacity battery charger.  
If the charging light flashes alternately in green and red  
color, a problem exists and charging is not possible. The  
terminals on the charger or battery cartridge are clogged  
with dust or the battery cartridge is worn out or  
damaged.  
Trickle charge (Maintenance charge)  
If you leave the battery cartridge in the charger to prevent  
spontaneous discharging after full charge, the charger will  
switch into its trickle charge (maintenance charge)mode  
and keep the battery cartridge fresh and fully charged.  
Tips for maintaining maximum battery life  
1. Charge the battery cartridge before completely dis-  
charged.  
Always stop tool operation and charge the battery car-  
tridge 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.

Switch action  
CAUTION:  
1
Before inserting the battery cartridge into the tool,  
always check to see that the switch trigger actuates  
properly and returns to the OFFposition when  
released.  
To start the tool, simply pull the switch trigger. Release the  
switch trigger to stop.  
1. Switch trigger  
Hold the tool straight when inserting/operating. Use the tool  
within the effective vibrations range at equidistant intervals.  
The effective air bubble removal range is about ten times  
diameter of the vibrating head, or around 250 mm (9-27/32).  
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.  
OPERATION  
001960  
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 con-  
crete 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.  
001961  
When the coarse aggregates segregates when placing  
concrete, shovel out the coarse aggregate and put it  
where there is plenty of mortar. Then use the tool on it.  
Dont leave coarse aggregate in the segregated  
condition.  
10  
 
When concreting a slope site, always pour from the bottom at  
the beginning. This way the weight of the freshly poured con-  
crete and vibration will lead to effective removal of air bub-  
bles. 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 attempting to  
perform inspection or maintenance.  
EN0001-1
