Depth gauge
003180
3 The depth gauge is convenient for drilling holes of uniform
depth. Insert the depth gauge into the hole in the grip base.
Adjust the depth gauge to the desired depth and then tighten
the clamp screw to secure the depth gauge.
NOTE:
• The depth gauge cannot be used at the position where
the depth gauge strikes against the tool body.
Dust cup (optional accessory)
003186
Use the dust cup to prevent dust from falling over the tool
and on yourself when performing overhead drilling opera-
1
tions. 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 as
follows.
Hammer drilling operation
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 slip-
ping 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 sev-
eral 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.
