OPERATION
Electronic Feedback Control Circuit
These hammers have an Electronic Feedback Con-
trol Circuit (EFCC) which helps improve the operation
and life of the tool.
Feedback Control
The electronic speed control circuit allows the tool to
maintain constant speed and torque between no-load
and load conditions.
The Soft-Start feature reduces the amount of torque
reaction to the tool and the user. This feature gradu-
ally increases the motor speed up from zero to the
speed set by the speed control dial.

use an OSHA compliant dust extraction solution
when working in dusty situations.
To reduce the risk of injury, keep hands and cord
away from the bit and all moving parts.
To reduce the risk of injury, always use a side
handle when using this tool. Always brace or
hold securely.
