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 (SDS PLUS) against stop�
When removing, extract the borer (chisel) from the
chuck 1 (SDS PLUS)�
• Release fixing bush 3�
• Test the borer (chisel) fixing by trying to remove it
from chuck 1 (SDS PLUS)�
Gloves are to be used when removing the
borer (chisel) from chuck 1 (SDS PLUS),
as the borer (chisel) may be dangerously
hot after long drilling.
Adapter for chuck SDS PLUS
• SDS PLUS adapter 17 and screw 18 enable using
gear rim chuck 16�
• Never use SDS PLUS adapter 17 in the impact
drilling or chiselling operation modes�
• Drills that don't belong to the SDS PLUS system are
not allowed for the percussion drilling�
Mounting / dismounting of the gear rim chuck (see
fig. 5-6)
• Screw the gear rim chuck 16 onto the adapter 17
(SDS PLUS) and lock it in with the screw 18 (see fig. 5).
