Depth gauge

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.
Dust cup
001300
Use the dust cup to prevent dust from falling over the tool and on yourself
when performing overhead drilling operations. Attach the dust cup to the bit as
shown in the figure. The size of bits which the dust cup can be attached to is
1
as follows.
Dust cup 5
Dust cup 9
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

Set the change lever to the
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 posi-
tion 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 repeating this several times, the hole will be cleaned out and normal
drilling may be resumed.
CAUTION:
• There is a tremendous and sudden twisting force exerted on the tool/bit
at the time of hole break-through, when the hole becomes clogged with
chips and particles, or when striking reinforcing rods embedded in the
concrete. Always use the side grip (auxiliary handle) and firmly hold the
tool by both side grip and switch handle during operations. Failure to do
so may result in the loss of control of the tool and potentially severe
injury.
