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.
• 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.
• 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
"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.

(Fig. 28)
Rest the tool on the table with the bit end pointing
upwards. This will allow the old grease to collect inside
the crank housing.
Wipe out the old grease inside and replace with a fresh
grease (30 g). Use only Makita genuine hammer grease
(optional accessory). Filling with more than the specified
amount of grease (approx. 30 g) can cause faulty
hammering action or tool failure. Fill only with the
specified amount of grease.
CAUTION:
• Be careful not to damage the connector or lead wires
especially when wiping out the old grease.
To reassemble the tool, follow the disassembling
procedure in reverse.
CAUTION:
• Do not tighten the crank cap excessively. It is made of
resin and is subject to breakage. (Fig. 29)
Connect the connector firmly and then reinstall the
handle.
CAUTION:
• Be careful not to damage the connector or lead wires
especially when installing the handle.
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.
