Speed adjusting dial
The blows per minute can be adjusted by turning the

CAUTION:
Do not turn the adjusting dial when
the tool is running. Failure to do so may result in
the loss of control of the tool and cause an injury.
NOTICE:
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.
NOTE:
Soft no-load rotation function
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 reach the numbers as
shown in the table.
When temperature is low, the tool may not have this
function even with the motor rotating.
