Charge the battery cartridge before completelydischarged.Always stop tool operation and charge the bat-tery 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 tempera-ture at 10°C – 40°C (50°F – 104°F). Let a hot bat-tery cartridge cool down before charging it.FUNCTIONAL DESCRIPTIONCAUTION:• Always be sure that the tool is switched off and the bat-tery cartridge is removed before adjusting or checkingfunction on the tool.Installing or removing battery cartridge(Fig. 1 & 2)• Always switch off the tool before insertion or removal ofthe battery cartridge.• To remove the battery cartridge, first open the batterycartridge cover.

Release theswitch lever to stop.Switch lever can be pulled from either top or back side ofthe tool.OPERATIONHold the tool straight when inserting/operating. Use thetool within the effective vibration range at equidistantintervals. The effective air bubble removal range is aboutten times the diameter of the vibrating head, or around250 mm.Do not use this tool to move concrete within a form. Themortar will just move away and the coarse aggregate willremain, causing segregation. (Fig. 4)Effective leveling and removal of air bubblesRemoval of the air bubbles is complete after you haveworked the tool throughout each effective range, the con-crete stops shrinking, and the mortar has risen evenly tothe surface, giving off a light appearance. Gently removethe operating tool not to leave holes.NOTE:• Vibrating too long in a single place causes concretesegregation.• When the coarse aggregate segregates when placingconcrete, shovel out the coarse aggregate and put itwhere there is plenty of mortar. Then use the tool on it.Don’t leave coarse aggregate in the segregated condi-tion.When concreting a slope site, always pour from the bot-tom at the beginning. This way the weight of the freshlypoured concrete and vibration will lead to effectiveremoval of air bubbles. Conversely, if the pouring is donefirst from above, the mortar will separate and eventuallyslide to the bottom.
