Selecting the action mode

For Models HR2300, HR2600, HR2601

Fig.6

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

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 halfway between the mode symbols, the
tool may be damaged.

•

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

symbol. Use a

twist drill bit or wood bit.

Hammering only

Fig.9

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

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 positions.

•

When changing from the

symbol mode to the

symbol 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.
