Electronic function

The tool is equipped with the electronic functions for
easy operation.
• Soft no-load rotation function
(For Model HM1512 only)
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.
When temperature is low, the tool may not have
this function even with the motor rotating.
• Soft start
The soft-start function minimizes start-up shock,
and makes the machine start smoothly.

Always be sure that the tool is
