Insert the bit into the tool. Turn the bit and push it in until it
engages.
After installing, always make sure that the bit is securely
held in place by trying to pull it out.

To remove the bit, pull the chuck cover down all the way
and pull the bit out.
Depth gauge

012286
The depth gauge is convenient for drilling holes of
uniform depth. Loosen the thumb screw and adjust the
depth gauge to the desired depth. After adjusting, tighten
the thumb screw firmly.
NOTE:
•
The depth gauge cannot be used at the position
where the depth gauge strikes against the gear
housing/motor housing.
OPERATION
Always use the side grip (auxiliary handle) and firmly
hold the tool by both side grip and switch handle during
operations.
Hammer drilling operation
012292
Set the action mode changing knob 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
repeating this several times, the hole will be cleaned out
and normal drilling may be resumed.
Set the action mode changing knob to the
symbol.
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.
NOTE:
Eccentricity in the bit rotation may occur while operating
the tool with no load. The tool automatically centers itself
during operation. This does not affect the drilling
precision.

Use the optional drill chuck assembly. When installing it,
refer to the section "Installing or removing the bit".
CAUTION:
•
Never use "rotation with hammering" when the drill
chuck is installed on the tool. The drill chuck may
be damaged.
Also, the drill chuck will come off when reversing
the tool.
•
Pressing excessively on the tool will not speed up
the drilling. In fact, this excessive pressure will only
serve to damage the tip of your bit, decrease the
tool performance and shorten the service life of the
tool.
•
There is a tremendous twisting force exerted on the
tool/bit at the time of hole breakthrough. Hold the
tool firmly and exert care when the bit begins to
break through the workpiece.
