VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
Your tool is equipped with a variable speed
trigger switch. The tool can be turned "ON" or
"OFF" by squeezing or releasing the trigger.
The speed can be adjusted from the minimum
to maximum nameplate RPM by the pressure
you apply to the trigger. Apply more pressure
to increase the speed and release pressure to
decrease speed (Fig. 1).
REVERSING SWITCH LEVER
The reversing switch lever is located above the
trigger switch and is used to reverse rotation of
the bit. The reversing switch should only be
activated when the motor is "OFF" and when bit
is at a complete standstill (Fig. 1).
To use tool in "Forward" rotation move lever to
left side of tool, to "Reverse" the rotation of the
bit move the lever to the right side of the tool.
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.
To tighten, hold the chuck collar firmly with one
hand and securely tighten the chuck sleeve
with the other hand (Fig. 2).
To prevent friction burns, or
W RNING
possible hand injury, do not
loosen or tighten the chuck by using the power
of the drill.
REMOVING CHUCK
Open the chuck all the way, remove left-hand
thread screw inside chuck by turning it
clockwise (Fig. 3).
Insert the short arm of a 3/8" hex key wrench
and close jaws on flats of wrench (Fig. 4).
Strike long arm of wrench sharply counter-
clockwise, remove wrench and unthread chuck
from spindle.
INSTALLING CHUCK
Always keep the spindle threads, the threads
of the chuck and securing screw free of debris.
To install a chuck, reverse "removing the
chuck" procedure.
