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

CAUTION:

•

Before inserting the battery cartridge into the tool, always check to see that the switch lever actuates properly and returns to the "OFF" position when released.

To start the tool, simply pull the switch lever. Release the switch lever to stop. Switch lever can be pulled from either top or back side of the tool.

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.

OPTIONAL ACCESSORIES

CAUTION:
