General Power Tool Safety
Warnings

WARNING Read all safety warnings and all

instructions. Failure to follow the warnings and

instructions may result in electric shock, fire and/or
serious injury.

Save all warnings and
instructions for future reference.

The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.

Work area safety

1. Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

2. Do not operate power tools in explosive

atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools

create sparks which may ignite the dust or fumes.

3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.

Electrical safety

4. Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will

reduce risk of electric shock.

5. Avoid body contact with earthed or grounded

surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of

electric shock if your body is earthed or grounded.

6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.

7. Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords

increase the risk of electric shock.

8. When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of
a cord suitable for outdoor use reduces the risk of
electric shock.

9. If operating a power tool in a damp location is

unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of an

GFCI reduces the risk of electric shock.

Personal safety

10.

Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the influence of drugs, alcohol or medication.

the risk of starting the power tool accidentally.

20. Store idle power tools out of the reach of

children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are

dangerous in the hands of untrained users.

21. Maintain power tools. Check for misalignment

or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents

are caused by poorly maintained power tools.

22. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.

23. Use the power tool, accessories and tool bits

etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the power

tool for operations different from those intended

OPERATION

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.

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
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 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. 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. 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.

• Never use gasoline, benzine, thinner, alcohol or

the like. Discoloration, deformation or cracks may

result.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
