2. Insert the Depth Gauge (12) in the hole at the top of the
Auxilary Handle (8) (Fig. B).
3. The Auxiliary Handle (8) can be swivelled around 360°
to find the position that offers most support and the
easiest operation.
4. The Depth Gauge (12) helps keep an accurate depth
when drilling holes to a set depth.
5. To change the position of the Depth Gauge (12), turn the
grip of the Auxilary handle (8) anti-clockwise until the depth
gauge is loose enough to slide in the hole.
6. Set the depth, checking the depth with a steel rule for
most accurate measurement (Fig. C).
7. Then turn the handle grip clockwise to tighten both
the depth stop and the auxiliary handle in the required
position (Fig. D).

Installing and removing bits

NOTE: The fitted chuck is only suitable for SDS-Plus fitment
accessories. The SDS-Plus bit enables easy and safe bit
replacement.
CAUTION. Always ensure that the drill is switched off and
B
plug is removed from the power socket before installing or
removing drill bits.
Before inserting an SDS-Plus bit always ensure that the bit
end is clean and greased.
1. Pull back the Locking Sleeve (10) and insert the bit into
the chuck opening taking care that the splines on the
shaft of the bit locate properly within the chuck (Fig. E).
2. Test for proper location by releasing the Locking Sleeve
(10) and giving the bit a sharp pull. If the bit can be
removed, again pull back the locking sleeve, rotate the bit
a fraction of a turn and re-insert it into the chuck (Fig. F).
Note: This sometimes requires that you slightly twist the bit
D
to locate the fitment slots.
3. Release the locking sleeve and again test for proper
location. Repeat if necessary until you are sure that the
bit is properly secured.
4. To remove the bit, pull back
the Locking Sleeve (10),
remove the bit, and release
the locking sleeve (Fig. G).
Note. Hammer action drilling is
only possible with the drill set for
forward rotation.
