HOW TO USE THE DRILL
GENERAL DRILLING
1.Be sure drill bit is securely gripped in chuck. (See INSTALLING AND REMOVING DRILL BIT).
2.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.
3.Locate exact center for hole to be drilled and using a center punch, make a small dent in work.
4.Place tip of drill bit in dent made by center punch, hold drill square with work, and start the motor.
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 overheat resulting in bodily injury or damaged drill bits.
CAUTION: BE ALERT and brace yourself against the twisting action of the drill, should the bit jam in the work.
5.If drill stalls or becomes jammed in the hole, release trigger immediately, remove 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. The direction of rotation may be reversed to help free a jammed bit.
6.Reduce the pressure on the drill just before the bit cuts through the work to avoid splintering wood or stalling in metal.
7.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 DRlLLlNG, 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1.When using twist drills in wood, they should be withdrawn from the hole frequently to clear chips built up in flutes to avoid overheating and burning work.
2.If a backing block is used to keep back of work from splintering, it should be clamped securely in place. If a backing block is not used with spade bits or auger bits, ease up pressure as soon as bit point breaks through work, and complete the hole from the opposite side.
DRILLING METAL
In addition to the instructions listed under GENERAL DRILLING, the following also apply:
CAUTION: When drilling metal, jamming of bit is more likely than when drilling other materials.
1.Use only good quality sharp high speed steel twist bits when drilling metal.
2.Start drilling with slow speed and gradually increase speed as drill cuts.
