– Manually rotate the auger until a click is heard, indicating automatic locking.
To remove the auger: turn the emergency lever, manually rotate and remove the auger from the spindle.
4.1.2) Assemble the guard PRM-U (See Fig. 1)
To fi t the detachable guard PRM-U (21), complete with end piece (32), proceed as follows:
– Unscrew the guard knob (22) from each shaft (24).
– Slide the shafts (24) into the brass bushes on the detachable guard (21): until they protrude suf-
fi ciently, to enable the guard nuts (22) to be fi tted.
Tighten the guard nuts (22) by hand.
The SD-15P-ECO drill is supplied complete with TPM 200-26 end piece; should it need to be replaced,
simply unscrew it by hand and screw on the new end piece suitable for the centring required.
