For preparation of the item being shipped, consulting an expert for hazardous material is required. Please also observe possibly more detailed national regulations. Tape or mask off open contacts and pack up the battery in such a manner that it cannot move around in the packaging.
11. Follow your local regulations relating to disposal of battery.

SAVE THESE INSTRUCTIONS.

CAUTION: Only use genuine Makita batteries.

• Use of non-genuine Makita batteries, or batteries that have been altered, may result in the battery bursting causing fires, personal injury and amage. It will also void the Makita warranty for the Makita tool and charger.

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 battery cartridge if you do not use it for a long period (more than six months).

FUNCTIONAL DESCRIPTION

CAUTION:

• Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool.

Installing or removing battery cartridge (Fig. 1 & 2)

• Always switch off the tool before insertion or removal of the battery cartridge.
• To remove the battery cartridge, first open the battery cartridge cover. To open the cover, press its recessed part and pivot it with the recessed part depressed. And then withdraw it from the tool while sliding the button on the front 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 you can see the red part on the upper side of the button, it is not locked completely. Insert it fully until the red part cannot be seen. 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.

Indicating the remaining battery capacity (Fig. 3)

Only for battery cartridges with the indicator
Press the check button on the battery cartridge to indicate the remaining battery capacity. The indicator lamps light up for few seconds.

015658

NOTE:

• Depending on the conditions of use and the ambient temperature, the indication may differ slightly from the actual capacity.

Switch action (Fig. 4)
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 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.
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. (Fig. 5)

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. Conversely, if the pouring is done first from above, the mortar will separate and eventually slide to the bottom. (Fig. 6)

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 Service Centers, always using Makita replacement parts.
