NOTE:

•

Blows at no load per minute becomes smaller than

those on load in order to reduce vibration under no

load, but this does not show trouble. Once

operation starts with a bit against concrete, blows

per minute increase and get to the numbers as

shown in the table. When temperature is low and

there is less fluidity in grease, the tool may not

have this function even with the motor rotating.

CAUTION:

•

If the tool is operated continuously at low speeds

for a long time, the motor may 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

CAUTION:

•

Do not rotate the change lever when the tool is

running. The tool will be damaged.

To avoid rapid wear on the mode change

mechanism, be sure that the change lever is

positions.
