▼ INSTALLING AND REMOVING
ACCESSORIES WHEN USING 3-JAW
CHUCK
For small bits, open jaws enough to
insert the bit up to the flutes. For large
bits, insert the bit as far as it will go.
Center the bit as you close the jaws by
hand. This positions the bit properly,
giving maximum contact between the
chuck jaws and the bit shank (Fig. 6).
To tighten chuck, insert key into each of
the three key holes in succession and
tighten clockwise firmly.
The chuck can be released by using one
hole only.
Note: The 3-Jaw Chuck is for use only in
"Drill only" mode. The 3-Jaw Chuck is
not for use when drilling with
hammering action.
▶ Auxiliary Handle

auxiliary handle, which can be swiveled
360˚.
To reposition and/or swivel the handle,
loosen the hand grip, move the handle
to the desired position along the barrel
and securely retighten the hand grip
(Fig. 7).
▶ Depth Gauge
Your drilling depth can be pre-set and/or
repeated by using the depth gauge.
Setting depth: After the auxiliary handle
is installed, make sure the accessory has
