SOFT START FEATURE
The soft start feature allows you to build up speed slowly, thus
preventing the drill bit from walking off the intended hole position
when starting. The soft start feature also reduces the immediate
torque reaction transmitted to the gearing and the operator if the
hammer is started with the drill bit in an existing hole.
