Installing or removing battery cartridge
(Fig. 3)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while pressing the button on the side of the
cartridge as shown in the figure. (Fig. 4)
• To insert the battery cartridge, hold it so that the battery
cartridge front shape fits to that of the battery
installment opening 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 cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
