FUNCTIONAL DESCRIPTION

CAUTION:

• Always be sure that the tool is switched off and

unplugged before adjusting or checking function on the

tool.

Switch action

FOR MODEL HR4011C

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. Release

the switch trigger to stop. (Fig. 1)

FOR MODELS HR4010C AND HR4001C

Trigger switch

CAUTION:

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

the switch trigger actuates properly and returns to the

“OFF” position when released.

• This switch functions when setting the tool in sym-

bol and symbol modes.

To start the tool, simply pull the switch trigger. Release

the switch trigger to stop. (Fig. 1)

Slide switch

CAUTION:

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

the tool is switched off.

• This switch functions only when setting the tool in

symbol action mode.

When using the tool in the hammering mode for a long

time, the slide switch is available. To start the tool, push

the “I (ON)” side of the switch lever. To stop the tool, push

the “O (OFF)” side of the switch lever. (Fig. 2)

Speed change (Fig. 3)

The revolutions and blows per minute can be adjusted

just by turning the adjusting dial. The dial is marked 1

(lowest speed) to 5 (full speed).

Refer to the table below for the relationship between the

number settings on the adjusting dial and the revolutions/

blows per minute.

CAUTION:

• If the tool is operated continuously at low speeds for a

long time, the motor will get overloaded, resulting in

tool malfunction.

• The speed adjusting dial can be turned only as far as 5

and back to 1. Do not force it past 5 or 1, or the speed

adjusting function may no longer work.

Selecting the action mode

Rotation with hammering (Fig. 4 & 5)

For drilling in concrete, masonry, etc., depress the lock

button and rotate the change lever so that the pointer

points to the symbol. Use a tungsten-carbide tipped

bit.

Hammering only

FOR MODELS HR4001C AND HR4010C (Fig. 6)

For chipping, scaling or demolition operations, depress

the lock button and rotate the change lever so that the

pointer points to the symbol. Use a bull point, cold

chisel, scaling chisel, etc.

For long time hammering (FOR MODELS HR4001C

AND HR4010C ONLY) (Fig. 7)

For chipping, scaling or demolition operations, depress

the lock button and rotate the change lever so that the

pointer points to the symbol. Use a bull point, cold

chisel, scaling chisel, etc.

CAUTION:

• When using the tool in the symbol mode, the switch

trigger does not work and only the slide switch works.

FOR MODEL HR4011C (Fig. 8)

For chipping, scaling or demolition operations, depress

the lock button and rotate the change lever so that the

pointer points to the symbol. Use a bull point, cold

chisel, scaling chisel, etc.

CAUTION:

• Do not rotate the change lever 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 change lever is always positively

located in one of the two or three action mode posi-

tions.

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.

Indicator lamp (Fig. 9)

The green power-ON indicator lamp lights up when the

tool is plugged. If the indicator lamp does not light up, the

mains cord or the controller may be defective. The indica-

tor lamp is lit but the tool does not start even if the tool is

switched on, the carbon brushes may be worn out, or the

controller, the motor or the ON/OFF switch may be defec-

tive.

The red service indicator lamp lights up when the carbon

brushes are nearly worn out to indicate that the tool

needs servicing. After approx. 8 hours of use, the motor

will automatically be shut off.
