3. OPERATION
SWITCHES
Your Drill is equipped with a variable
speed switch that lets you run the
tool at the proper speed for each job.
To turn the tool ON, depress the trig¬
ger switch (A) shown in Figure 1. The
farther you depress the trigger, the
faster the drill will run. To turn the
tool OFF, release the trigger.
NOTE: Use lower speeds for STARTING HOLES WITHOUT A CENTER
PUNCH, DRILLING IN METAL OR PLASTICS, DRIVING OR REMOVING
SCREWS, DRILLING CERAMICS. OR MIXING PAINT. Higher speeds are
better for DRILLING WOODS AND COMPOSITION BOARDS, AND FOR
USING ABRASIVE AND POLISHING ACCESSORIES.
REVERSING SWITCH
For removing screws or easing drill bits out of tight holes, slide the Reversing
Switch, Figure 2, toward "R" to reverse the drill motor. The trigger switch
must be released to the "OFF" position before moving the reversing switch.
After any reversing operations, return switch to the forward "F" position.
CHUCK
TURN OFF AND UNPLUG DRILL
Open chuck jaws by turning collar with fingers and
insert shank of bit about 3/4" into chuck, lighten
the chuck collar by hand. Place the chuck key into
one of the three holes and tighten securely as shown
in the figure. Repeat the process for the two remain¬
ing holes. It's important to tighten the chuck in all
three holes. To release the bit after drilling, loosen
the chuck in one hole only and then continue loosen¬
ing by hand.
CHUCK KEY
To prevent loss, the chuck key for your drill has been especially designed to clip on¬
to the power cord. The key need not be removed from the cord in order to use it.
In fact, it's a good idea to clip it to the cord near the plug and leave it there. That
way you will be sure to unplug the drill when using the chuck key.
In those instances where it may be desirable to remove the key from the power cord,
simply grasp the key firmly and pull it off. When you've finished with it clip it back
to the cord as shown.
Do not lubricate the inside of the chuck or the three jaws. A light film of oil can be
applied to the outside of the chuck to prevent rust from forming.
