Maintenance; Optional Accessories - Makita HR2470 Instruction Manual

For Model HR2470T/HR2470FT
Use the quick change drill chuck as standard equipment.
When installing it, refer to "Changing the quick change
chuck for SDS-plus" described on the previous page.
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far as
it will go. Hold the ring firmly and turn the sleeve
clockwise to tighten the chuck. To remove the bit, hold
the ring and turn the sleeve counterclockwise.
Set the action mode changing knob to the m symbol.
You can drill up to 13 mm diameter in metal and up to
32 mm diameter in wood.
CAUTION:
• Never use "rotation with hammering" when the quick
change drill chuck is installed on the tool. The quick
change 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 differ from
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).
