Depth gauge (Fig. 8)
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 (Fig. 9)
Set the action mode changing knob 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 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.
CAUTION:
• There is 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.
Drilling in wood or metal (Fig. 10)
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.
• A stuck bit can be removed simply by setting the
reversing switch to reverse rotation in order to back
out. However, the tool may back out abruptly if you do
not hold it firmly.
• Always secure small workpieces in a vise or similar
hold-down device.

Diamond core drilling
When performing diamond core drilling operations,
always set the change lever to the m position to use
"rotation only" action.
CAUTION:
• If performing diamond core drilling operations using
"rotation with hammering" action, the diamond core bit
may be damaged.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.

To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized Service Centers, always using Makita
replacement parts.
Noise
The typical A-weighted noise level determined according
to EN62841-2-6:
Sound pressure level (L
Sound power level (L
Uncertainty (K): 3 dB (A)
NOTE:
• The declared noise emission value(s) has been
measured in accordance with a standard test method
and may be used for comparing one tool with another.
• The declared noise emission value(s) may also be
used in a preliminary assessment of exposure.
WARNING:
• Wear ear protection.
• The noise emission during actual use of the power
tool can
depending on the ways in which the tool is used
especially what kind of workpiece is processed.
• Be sure to identify safety measures to protect the
operator that are based on an estimation of
exposure in the actual conditions of use (taking
account of all parts of the operating cycle such as
the times when the tool is switched off and when it
is running idle in addition to the trigger time).
Vibration
The vibration total value (tri-axial vector sum) determined
according to EN62841-2-6:
Work mode: hammer drilling into concrete
Vibration emission (a
Uncertainty (K): 1.5 m/s
NOTE:
• The declared vibration total value(s) has been
measured in accordance with a standard test method
and may be used for comparing one tool with another.
• The declared vibration total value(s) may also be used
in a preliminary assessment of exposure.
