and symbol modes.

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

the switch trigger to stop.

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 MODEL HR4501C AND HR4510 (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 HR4501C

AND HR4510C 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.

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

positions.

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.
