FORWARD/REVERSING LEVER &
TRIGGER LOCK
Your tool is equipped with a forward/reversing
lever and trigger lock located above the trigger
(Fig. 1). This lever was designed for changing
rotation of the chuck, and for locking the
trigger in an"OFF" position to help prevent
accidental starts. For forward rotation, (with
the chuck pointed away from you) move lever
to the far left. For reverse rotation move the
lever to the far right. To activate trigger lock
move lever to the center off position.
INSERTING BIT
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.
KEYED MODELS
To tighten chuck, insert key into each of the
three key holes in succession and tighten
firmly. The chuck can be released by using one
hole only (Fig. 3).
KEYLESS MODELS
To tighten, hold the chuck collar firmly with
one hand and securely tighten the chuck
sleeve with the other hand (Fig. 4).
