Makita HR2310T, Instruction Manual

Hammering only (Fig. 9)

For chipping, scaling or demolition operations, rotate the
action mode changing knob to the 

g

 symbol. Use a bull

point, cold chisel, scaling chisel, etc.

CAUTION:

• Do not rotate the action mode changing knob when the

tool is running under load. The tool will be damaged.

• To avoid rapid wear on the mode change mechanism,

be sure that the action mode changing knob is always
positively located in one of the three action mode posi-
tions.

• When changing from the 

g

 symbol mode to the 

m

 sym-

bol mode, the action mode changing knob may no
longer move in the 

symbol position. At this time,

turn the tool on or turn the chuck by hand in the 
symbol position and then rotate the action mode
changing knob. Forcing the action mode changing knob
may cause tool damage.

Torque limiter

The torque limiter will actuate when a certain torque level
is reached. The motor will disengage from the output
shaft. When this happens, the bit will stop turning. 

CAUTION: 

• As soon as the torque limiter actuates, switch off the

tool immediately. This will help prevent premature wear
of the tool.

• Bits such as hole saw, which tend to pinch or catch

easily in the hole, are not appropriate for this tool. This
is because they will cause the torque limiter to actuate
too frequently.

ASSEMBLY

CAUTION:

• Always be sure that the tool is switched off and

unplugged before carrying out any work on the tool.

Side grip (auxiliary handle) (Fig. 10) 

CAUTION:

• Always use the side grip to ensure operating safety. 

Install the side grip so that the protrusions on the grip fit
in between the grooves on the tool barrel. Then tighten
the grip by turning clockwise at the desired position. It
may be swung 360° so as to be secured at any position. 

Bit grease

Coat the bit shank head beforehand with a small amount
of  bit  grease  (about  0.5 – 1 g).
This chuck lubrication assures smooth action and longer
service life. 

Installing or removing the bit

Clean the bit shank and apply bit grease before installing
the bit. 

(Fig. 11)

Insert the bit into the tool. Turn the bit and push it in until
it engages. 

(Fig. 12)

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.

Bit angle (when chipping, scaling or demolishing)

For Models HR2310T, HR2610, HR2610T, HR2611F,
HR2611FT

The bit can be secured at the desired angle. To change
the bit angle, rotate the action mode changing knob to
the O symbol. Turn the bit to the desired angle.

 (Fig. 14)

Rotate the action mode changing knob to the 

g

 symbol.

(Fig. 15)

Then make sure that the bit is securely held in place by
turning it slightly.

Depth gauge 

The depth gauge is convenient for drilling holes of uni-
form depth. 

(Fig. 16)

Press the lock button on the grip base in the direction of
arrow shown in the figure and with the lock button being
pressed insert the depth gauge into the hex. hole in the
grip base. 

(Fig. 17)

At this time, the depth gauge needs to be inserted so that
its toothed side is directed to the toothed side of hex hole
marking on the grip base as shown in 

Fig. 18

.

Adjust the depth gauge to the desired depth by moving it
back and forth while pressing the lock button. After the
adjustment, release the lock button to lock the depth
gauge. 

(Fig. 19)

NOTE:

• Inserting the depth gauge with its toothed side not

directed to the toothed side of hex hole marking on the
grip base as shown in the figure does not allow the
depth gauge to be locked.

Dust cup (Fig. 20)

Use the dust cup to prevent dust from falling over the tool
and on yourself when performing overhead drilling
operations. Attach the dust cup to the bit as shown in

Fig. 20

. The size of bits which the dust cup can be

attached to is as follows.

There is another type of dust cup (accessory) which
helps you prevent dust from falling over the tool and on
yourself when performing overhead drilling operations.

Installing or removing the dust cup

Before installing the dust cup, remove the bit from the
tool if installed on the tool. Install the dust cup (acces-
sory) on the tool so that the 

△

 symbol on the dust cup is

aligned with the grooves in the tool. 

(Fig. 21)

To remove the dust cup, pull the chuck cover in the direc-
tion as shown in 

Fig. 22

 and with the chuck cover pulled

take the bit out of the tool.
And then grab the attachment at the foot of dust cup and
take it out. 

(Fig. 23)

NOTE:

• When installing or removing the dust cup, the cap may

come off the dust cup. At that time, proceed as follows.
Remove the bellows from the attachment and fit the
cap with its carved side facing upward so that the
groove in the cap fits in the inside periphery of the
attachment. Finally, mount the bellows that has been
removed.
