Always switch off the tool before insertion or

To remove the battery cartridge, 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

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.
