Borers SDS PLUS , due to the design
peculiarities of chucks SDS PLUS , can move
freely within a certain range� This is why a
radial run-out appears at no-load idle running,
which is automatically centred at drilling� It does not
influence hole-drilling accuracy.
•
Before installing the borer (chisel), clean it and apply
a thin oil layer�
• Move fixing bush 3
back and hold it in this position
(see fig. 4).
•
When mounting, insert (slightly twisting) the borer
(chisel) into the chuck
1

chuck

(SDS PLUS) �
• Release fixing bush 3

Gloves are to be used when removing the

as the borer (chisel) may be dangerously
hot after long drilling.
