Diamond core drilling
CAUTION:
• If performing diamond core drilling operations using
“rotation with hammering” action, the diamond core bit
may be damaged.
When performing diamond core drilling operations,
always set the change lever to the
m
position to use
“rotation only” action.
Operation when using the dust cup (optional
accessory) (Fig. 38)
Operate the tool with the dust cup against the ceiling
surface.
NOTE:
• The dust cup (optional accessory) is intended only for
drilling in the ceramic workpiece such as concrete and
mortar. Do not use the tool with the dust cup when
drilling in metal or similar. Using the dust cup for drilling
in the metal may damage the dust cup due to the heat
produced by small metal dust or similar.
• Empty the dust cup before removing a drill bit.
• When using the dust cup, make sure that the dust cap
is mounted on it securely.
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.

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 differ from the declared value(s)
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).
