Always switch off the tool before installation or
•
removal of the battery cartridge.
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 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.
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.
