Makita HR2310T, Instruction Manual

8

7.

In cold weather or when the tool has not been
used for a long time, let the tool warm up for a
while by operating it under no load. This will
loosen up the lubrication. Without proper warm
up, hammering operation is difficult.

8.

Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.

9.

Hold the tool firmly with both hands.

10. Keep hands away from moving parts.
11. Do not leave the tool running. Operate the tool

only when hand-held.

12. Do not point the tool at any one in the area when

operating. The bit could fly out and injure some-
one seriously.

13. Do not touch the bit or parts close to the bit

immediately after operation; they may be
extremely hot and could burn your skin.

14. Some material contains chemicals which may be

toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.

SAVE THESE INSTRUCTIONS.

WARNING:

DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to safety rules for the subject product. MISUSE or
failure to follow the safety rules stated in this instruc-
tion manual may cause serious personal injury.

FUNCTIONAL DESCRIPTION

CAUTION:

• Always be sure that the tool is switched off and

unplugged before adjusting or checking function on the
tool.

Switch action (Fig. 1)

CAUTION:

• Before plugging in the tool, always check to see that

the switch trigger actuates properly and returns to the
“OFF” position when released.

To start the tool, simply pull the switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop. For continuous opera-
tion, pull the switch trigger and then push in the lock but-
ton and then release the switch trigger. To stop the tool
from the locked position, pull the switch trigger fully, then
release it. 

Lighting up the lamps (Fig. 2)

For models HR2611F, HR2611FT

CAUTION:

• Do not look in the light or see the source of light

directly.

To turn on the lamp, pull the trigger. Release the trigger
to turn it off.

NOTE:

• Use a dry cloth to wipe the dirt off the lens of lamp. Be

careful not to scratch the lens of lamp, or it may lower
the illumination.

• Do not use thinner or gasoline to clean the lamp. Such

solvents may damage it.

Reversing switch action (Fig. 3)

CAUTION: 

• Always check the direction of rotation before operation. 
• Use the reversing switch only after the tool comes to a

complete stop. Changing the direction of rotation
before the tool stops may damage the tool.

• If the switch trigger can not be depressed, check to see

that the reversing switch is fully set to position 

 (A

side) or 

 (B side).

This tool has a reversing switch to change the direction of
rotation. Move the reversing switch lever to the 

 posi-

tion (A side) for clockwise rotation or to the 

 position (B

side) for counterclockwise rotation.

Changing the quick change chuck for SDS-plus

For Models HR2310T, HR2610T, HR2611FT

The quick change chuck for SDS-plus can be easily
exchanged for the quick change drill chuck.

Removing the quick change chuck for SDS-plus
(Fig. 4)

CAUTION:

• Before removing the quick change chuck for SDS-plus,

always remove the bit.

Grasp the change cover of the quick change chuck for
SDS-plus and turn in the direction of the arrow until the
change cover line moves from the 

 symbol to the 

symbol. Pull forcefully in the direction of the arrow.

Attaching the quick change drill chuck (Fig. 5)

Check the line of the quick change drill chuck shows the

 symbol. Grasp the change cover of the quick change

drill chuck and set the line to the 

 symbol.

Place the quick change drill chuck on the spindle of the
tool.
Grasp the change cover of the quick change drill chuck
and turn the change cover line to the 

 symbol until a

click can clearly be heard.

Selection action mode (Fig. 6)

For Models HR2300, HR2600, HR2601

This tool employs an action mode changing knob. Select
one of the two modes suitable for your work needs by
using this knob. 
For rotation only, turn the knob so that the arrow on the
knob points toward the 

m

 symbol on the tool body. 

For rotation with hammering, turn the knob so that the
arrow on the knob points toward the 

 symbol on the

tool body.

CAUTION:

• Always set the knob fully to your desired mode symbol.

If you operate the tool with the knob positioned half-
way between the mode symbols, the tool may be dam-
aged.

• Use the knob after the tool comes to a complete stop.

For Models HR2310T, HR2610, HR2610T, HR2611F,
HR2611FT

Rotation with hammering (Fig. 7)

For drilling in concrete, masonry, etc., rotate the action
mode changing knob to the 

 symbol. Use a tungsten-

carbide tipped bit.

Rotation only (Fig. 8)

For drilling in wood, metal or plastic materials, rotate the
action mode changing knob to the 

m

 symbol. Use a twist

drill bit or wood bit.
