Fastening by means of quick action bracing unit
In order to brace the drill rig by means of the quick action bracing
unit, the distance to the opposite wall must be between 1.7 m and 3 m.
Position the drill rig. Position the quick action bracing
unit as close as possible behind the support on the base
of the rig. Fix the drill rig by turning the crank (G)
clockwise. Secure in position by means of the
appropriate bolt (H).
Attention! It is important that the drill rig is firmly connected to the
surface. If not fixed correctly, injuries to the operator or damages to
the drilling unit may be caused. Uncontrolled movements during
drilling will cause the drill bit to hit the surface to be drilled which may
lead to a chipping of the segments. The drill bit might also tilt in the
bore hole which consequently will damage it.
Overload Protection
To protect the user, motor and drill bit, the
PLD 160
is equipped with a
mechanical, electrical and thermal overload protection.
Mechanical:
In case of sudden jamming of the drill bit, the drilling spindle
is unclutched from the motor by means of a slip clutch.
Electrical:
To warn the user against overstressing the tool by applying
to high an advance force, the handle includes a LED. It
does not light during idle run or at normal load. At overload,
it lights red. In that case the tool most be stress-relieved. In
