Porter-Cable 619 - How to Use the Drill

HOW TO HOLD THE DRILL
WARNING: The front end of drill may be made live if the tool drills
into live wiring in a wall, TO PREVENT ACCIDENTAL ELECTRICAL
SHOCK, DRILL MUST BE HELD AS SHOWN ON PAGE 8.
HOW TO USE THE DRILL
GENERAL DRILLING
1. Be sure drill bit is scurely gripped in chuck. (See INSTALLING
AND REMOVING DRILL BIT).
2. On reversing models only, set REVERSING SWITCH for
clockwise rotation.
3. Make sure work is held securely in vise or clamped in place prior
to starting drilling operation.
CAUTION - Loose work may spin and cause bodily injury.
4. Locate exact center for hole to be drilled and using a center
punch, make a small dent in work.
5. Place tip of drill bit in dent made by center punch, hold drill
square with work, and start the motor.
6. Apply steady, even pressure to keep drill bit cutting. Too little
pressure will keep the bit from cutting and dull the edges due to
excessive friction created by sliding over the surface.
CAUTION - Too much pressure may cause the bit to break or over
heat resulting in bodily injury or damaged drill bits.
CAUTION - Be ALERT and brace yourself against the twisting action
of the drill.
7. If drill stalls or becomes jammed in the hole, release trigger
immediately, removing drill bit from work and determine cause of
stalling or jamming. DO NOT SQUEEZE TRIGGER ON AND OFF IN
AN ATTEMPT TO FREE A STALLED OR JAMMED DRILL - THIS
WILL DAMAGE THE MOTOR. On reversing models only, the
direction of rotation may be reversed to help free a jammed bit. Be
sure direction of rotation is RESET before attempting to continue
drilling.
8. Reduce the pressure on the drill just before the bit cuts through
the work to avoid splintering wood or stalling in metal.
9. When bit has completely penetrated work and is spinning freely,
withdraw it from the work while the motor is still running, then turn off
drill.
DRILLING WOOD
In addition to the instructions listed under GENERAL DRILLING, the
following also apply:
1 . When using twist drills in wood, they should be withdrawn from
the hole frequently to clear chips built up in flutes to avoid
overheating and burning work.
