Tips for maintaining maximum battery
life
1. Charge the battery cartridge before completely
discharged.
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.
4. Charge the Nickel Metal Hydride battery car-
tridge when you do not use it for more than six
months.

• Always switch off the tool before insertion or
removal of the battery cartridge.
• To remove the battery cartridge, open the cover
and withdraw it from the tool while pressing the but-
tons on both sides 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 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 car-
tridge. If the cartridge does not slide in easily, it is
not being inserted correctly.
Switch action
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released.
To start the tool, simply pull the switch trigger. Release
the switch trigger to stop.
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.
