Comparison of Vibration level* and Time to reach
ELV (Exposure Limit of Vibration)**
*It is known as the tri-axial value and value at Directive of A(8).
**It means the maximum amount of vibration that an operator may be exposed to on any single day.

Longer life of Carbon brushes
features twice as long as that of Predecessor
model by employing large carbon brush.
Auto Cut-Out
Carbon Brush
protects commutator and
indicates time for
maintenance.
Rubberized Soft Grip
provides more control and
comfort while minimizing
hand fatigue and pain.
