The depth gauge is convenient for drilling holes of
uniform depth. Loosen the clamp screw and adjust the
depth gauge to the desired depth. After adjusting, tighten
the clamp screw firmly.
NOTE:
• The depth gauge cannot be used at the position
where the depth gauge strikes against the gear
housing/motor housing.

OPERATION
CAUTION:
• Always insert the battery cartridge all the way until it
locks in place. 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.
• When operating overhead, always make sure the
battery cartridge is locked securely so that it will not
be fallen out of the tool. If not, it may accidentally
fall out of the tool, causing injury to you or someone
around you.
Hammer drilling operation
003197
Set the change lever to the symbol.
Position the bit at the desired location for the hole, then
pull the switch trigger. Do not force the tool. Light
pressure gives best results. Keep the tool in position and
prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes
clogged with chips or particles. Instead, run the tool at an
idle, then remove the bit partially from the hole. By
